the slope of the line that passes through the point (2 4) and (3 8) is
Answer:
y - 4 = 4(x - 2)
Step-by-step explanation:
Please write these points as (2, 4) and (3, 8) (use commas and parentheses).
As we move from (2, 4) to (3, 8), x increases by 1 and y increases by 4. Thus, the slope is m = rise/run = 4/1 = 4
and the equation of the line through these two points (in point-slope form) is
y - 4 = 4(x - 2)
The slope of the line that passes through the point (2 4) and (3 8) is 4
The formula for calculating the equation of a line passing through the point (x1, y1) and (x2, y2) is expressed using the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Given the coordinate points (2 4) and (3 8), the slope is expressed as:
[tex]m=\frac{8-4}{3-2}\\m=\frac{4}{1}\\m = 4[/tex]
Hence the slope of the line that passes through the point (2 4) and (3 8) is 4

Many farmers use the height of their corn on July 4th as an indication of the entire crop. In a random sample of corn-stalk heights on July 4th in Columbia County, x⎯⎯⎯x = 25.6, s = 0.9 inch, and a histogram of the observations was bell-shaped.
Fill in the blank. (Give your answer to two decimal places.)
The approximate proportion of observations that lies between 23.8 and 27.4 is __
Answer:
0.9544
Step-by-step explanation:
Given that, his bell shapes and hence follows a normal distribution.
Mean (x) = 25.6 ; standard deviation (s) = 0.9
Approximate proportion of observation that lies between 23.8 and 27.4
Taking the Zscores of both values :
X - mean / standard deviation
(23.8 - 25. 6) / 0.9 = - 1.8/0.9 = - 2
P(Z < - 2) = 0.0228
Also;
(27.4 - 25.6) / 0.9 = 1.8 / 0.9 = 2
P(Z> 2) = 0.9772
0.9772 - 0.0228 = 0.9544
It is known that 1.4< square root of 2 <1.5. Find all possible values of the expression 2-square root of 2. How do I find out the second inequality?
Answer:
0.5<2-√2<0.6
Step-by-step explanation:
The original inequality states that 1.4<√2<1.5
For the second inequality, you can think of 2-√2 as 2+(-√2).
Because of the "properties of inequalities", we know that when a positive inequality is being turned into a negative, the numbers need to swap and become negative. So, the original inequality becomes -1.5<-√2<-1.4. (Notice how the √2 becomes negative, too). This makes sense because -1.5 is less than -1.4.
Using our new inequality, we can solve the problem. Instead of 2+(-√2), we are going to switch "-√2" with both possibilities of -1.5 and -1.6. For -1.5, we would get 2+(-1.5), or 0.5. For -1.4, we would get 2+(-1.4), or 0.6.
Now, we insert the new numbers into the equation _<2-√2<_. The 0.5 would take the original equation's "1.4" place, and 0.6 would take 1.5's. In the end, you'd get 0.5<2-√2<0.6. All possible values of 2-√2 would be between 0.5 and 0.6.
Hope this helped!
The possible values of 2-√2 will be in the range is 0.6 > 2 -√2 > 0.5.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
We have the given statement that 1.4 < √2 < 1.5
We have to determine the possible values of 2-√2 as 2+(-√2).
According to the question,
⇒ 1.4 < √2 < 1.5
Multiply by a minus sign (-) in the inequality
⇒ -1.4 > -√2 > -1.5
Adding 2 in the inequality
⇒ 2-1.4 > 2 -√2 > 2-1.5
⇒ 0.6 > 2 -√2 > 0.5
Hence, the possible values of 2-√2 will be in the range is 0.6 > 2 -√2 > 0.5.

If two lines have slopes of -2/9 and 9/2 are they perpendicular?
Answer:
[tex]\huge\boxed{\mathrm{Yes.}}[/tex]
Step-by-step explanation:
If the two lines are perpendicular, Multiplying their slopes must give the result of -1.
So, Let's Multiply these slopes.=> [tex]\sf -\frac{2}{9} * \frac{9}{2}[/tex]
=> -1
Since, the result of multiplying these slopes give -1, So, the two lines are perpendicular.
if ef bisects aed, aef=4x+3 and fed=7x-33 find m
Answer:
aef = fed = 51 degrees,
and the full angle aed = 102 degrees
Step-by-step explanation:
If ef bisects the angle aed, then the two angles it defines: aef and fed, must measure the same.
Therefore we can asume that aef = fed which numerically means:
4 x + 3 = 7 x - 33
so we solve for x:
33 + 3 = 7 x - 4 x
36 = 3 x
x = 36/3
x = 12 degrees
That means that the half angle aef measures:
aef = 4 x + 3 = 4 (12) + 3 = 48 + 3 = 51 degrees
Then we have that aef = fed = 51 degrees,
and the full angle aed = 51 + 51 = 102 degrees

The angle above the y is 90 degrees ( shown by the little square)
The 3 inside angles of a triangle need to equal 180.
Y = 180 - 90 - 48
Y = 42
Answer: y = 42°
Step-by-step explanation:
Triangle Sum Theorem states the sum of the angles of a triangle is 180°
y + 48° + 90° = 180°
y + 138° = 180°
y = 42°
5y + 2 + 6 + 2y 5y + 2(y + 3) + 2 combining like terms 6y − y + 2y + 10 − 4 + 2 Commutative Property Distributive Property arrowBoth arrowBoth arrowBoth
Answer:
Distributive Property
Step-by-step explanation:
5y + 2 + 6 + 2y
= 5y + 2(y + 3) + 2 This is the distributive property of multiplication w.r.t. addition
= 6y − y + 2y + 10 − 4 + 2
The distributive property of multiplication with respect to addition is the one which separates each term by using multiplication and then addition.
So we see that 2 is multiplied with y and 3 and then added with the like terms. If there was a minus sign the property would be distributive over subtraction.
Briyana has $150, and she needs to save at least $560 for a spring break trip. If she can save $45 per week, how long will it take her to save enough money? Let w= weeks saving money. Wrote an inequality to describe the situation.
Answer:
9.1 or 10 weeks
Step-by-step explanation:
First you need to create an equation: 150 + 45w = 560
You need to get the w by itself. To do this we need to take 150 from both sides: 150 (-150) + 45w = 560 (-150)
45w = 410
Now we have to divide both sides by 45:
w = 9.1
So it took Briyana just over 9 weeks to save $560 for spring break
I hope this helps
Let's work this out using the inequality it suggests.
We can use the form [tex]y=mx+b[/tex], but have the equals sign substitute out for whatever sign we need.
When you need to buy something, do you need to have more, less, or the same amount of money to buy something?
You need to have at least the same amount of money.
Which means that we'll be using the ≥ sign.
[tex]y\geq mw+b[/tex]
Now let's substitute in some values we know.
She has 150 to start off with, think of this as the y-intercept of the graph.
What variable represents the y-intercept?
You should've said b.
[tex]y\geq mw+150[/tex]
Now how much is she saving her week? $45.
Since this is how much she's saving every week, this represents the slope.
[tex]y\geq 45w+150[/tex]
Now, we can solve this plugging in 560 for [tex]y[/tex], which is how much money she needs.
[tex]560\geq 45x+150[/tex]
[tex]410\geq 45w[/tex]
[tex]\frac{82}{9}\geq w[/tex]
[tex]\frac{82}{9}[/tex] is 9.111 (repeating), but we need to round up to the nearest whole number because she probably doesn't deposit money constantly during the week, and rather all at once.
Which means that she needs to save money for 10 weeks to have enough money for the spring break trip.
Hope this helps.

Find an equation for a tangent plane z=e-x2-y2 at the point (0,0,1).
Answer: equation of the tangent plane is z = 1
Step-by-step explanation:
Given equation
z = e^(-x²-y²) at point (0,0,1)
now let z = f(x,y)
Δf(x,y) = [ fx, fy ]
= (-2xe^(-x²-y²)), (-2ye^(-x²-y²))
now
Δf (0,0) = [ 0, 0 ] = [ a, b ]
equation of the tangent plane therefore will be
z - z₀ = a(x-x₀) + b(y-y₀)
z - 1 = 0(x-0) + 0(y-0)
z - 1 = 0 + 0
z = 1
Therefore equation of the tangent plane is z = 1

1 liter is equivalent to a volume of 1000 cm3 (the same as 10 cm x 10 cm x 10 cm). If a beaker has a cross-section the size of the circle below, and a height of 10 cm, what is its volume
Answer:
[tex]Volume = \frac{220}{7}r^2[/tex]
Step-by-step explanation:
Given
Height = 10cm
See Attachment for complete question
Required
Determine the volume of the circle
The volume is calculated as thus;
[tex]Volume = \pi r^2h[/tex]
Take [tex]\pi[/tex] as [tex]\frac{22}{7}[/tex]
So; Volume becomes
[tex]Volume = \frac{22}{7} * r^2 * h[/tex]
Substitute 10 for h
[tex]Volume = \frac{22}{7} * r^2 * 10[/tex]
[tex]Volume = \frac{220}{7} * r^2[/tex]
Since, the value of the radius is not given;
The volume of the circle is:
[tex]Volume = \frac{220}{7}r^2[/tex]

3-2(x-4)= -5x-7 just the answer, also if you could can you please include the first step you would do in this equation.
Answer:
x = -4/3
Step-by-step explanation:
First, expand.
3 - 2(x - 4) = -5x - 7
Then, combine like factors.
3 - 2x + 8 = -5x + 7
11 - 2x = -5x + 7
Add 5x to both sides.
(11 - 2x) + 5x = (-5x + 7) + 5x
11 + 3x = 7
Subtract 11 from both sides.
(11 + 3x) - 11 = 7 - 11
3x = -4
Divide both sides by 3
(3x)/3 = -4/3
x = -4/3
Answer:
x = -6
Step-by-step explanation:
3-2(x-4)= -5x-7
Distribute
3 -2x +8 = -5x -7
Combine like terms
11 -2x = -5x -7
Add 5x to each side
11 -2x+5x = -5x-7+5x
11+3x = -7
Subtract 11 from each side
11+3x-11 = -7-11
3x = -18
Divide by 3
3x/3 = -18/3
x = -6
