Answer: The equation for the line is “y = 6x - 4”
Step-by-step explanation: To find this answer we will put it in slope-intercept form which is y = mx +b. To first find m which is the slope you subtract the the second y by the first y over the second x by the first x. It looks like this y2 - y1/ x2 - x1. After we find the slope which is 6, to find the y-intercept which is b we just plug a point we used to find the slope into the equation we have. It looks like this y = 6x + b —> 2 = 6(1) + b... I used (1,2). Then you solve for b by multiplying 1 by 6 and then subtracting 6 to both sides to get b by itself. So it goes from 2 = 6(1) + b into -4 = b. Then you just put -4 into b and you get the answer y = 6x - 4.
Have a nice day!
The area of a circle is 161 in. What is the radius?
Answer:
Approximately 7.16 in
Step-by-step explanation:
Hi there!
Area of a circle equation: [tex]A=\pi r^2[/tex] where r is the radius
Plug in the given area 161 in.²
[tex]161=\pi r^2[/tex]
Divide both sides by π to isolate r²
[tex]\frac{161}{\pi} =\frac{\pi r^2}{\pi} \\\frac{161}{\pi} =r^2[/tex]
Take the square root of both sides to isolate r
[tex]=r^2\\\sqrt{\frac{161}{\pi}} =r\\7.16=r[/tex]
Therefore, the radius of the circle is approximately 7.16 in.

whats this picture's eqeuation
Answer:
y = 2x + 3
Step-by-step explanation:
The slope can be found by taking two points, for instance: (0,3) and (3,9) which lie on the graph. Find the slope between the two, remember rise over run:
(9-3)/(3-0) = 6/3 = 2
The y-intercept is (0,3)
So b in the y= mx + b equation is 3.
m is the slope, so it is 2.
y = 2x + 3

Estimate the area of this figure below
Answer:
its 6 square units
Step-by-step explanation:
count how many boxes the that contain blue and devide by 2
Answer:
6
Step-by-step explanation:
There are 3 parts to each side. All three of them are the same so we only have to find the area of one different parts
Area of One Side
Triangle
The side of a square is 1 square unit.
each leg of the triangle is 1 unit
The area of 1 triangle = 1/2 * 1 * 1 = 1/2
Area of 1 side
There are 3 equal parts (3 triangles) that make up a side.
Area of the three triangles = 3 * 1/2 = 3/2 = 1.5
Area of all 4 sides
4 * 1.5 = 6
The area of the blue colored figure is 6 units.

In the design shown below, four semicircles are attached to a square whose area is 36 square centimeters. Which of the following is closest to the total area of the shaded semicircles, measured in square centimeters?
Answer:
56.549 cm (choice 1)
Step-by-step explanation:
If the area of the square if 36 cm, then each side is 6 cm.
That means the diameter for each semi circle is also 6 cm.
Formula for a semi circle is 1/2(πr²)
We need the radius, which is half the diameter. So the radius is 6÷2= 3
Now plug in to the formula.
A= 1/2(π3²)
A= 14.137 (nearest hundredths)
Now multiply that by 4, because there are 4 semi circles
4(14.137)= 56.549 cm (nearest hundredths)

what is the y-intercept for 3x^2 + 2x - 1
Answer:
y- intercept = - 1
Step-by-step explanation:
To find the y- intercept , let x = 0 in the equation and evaluate for y
y = 3(0)² + 2(0) - 1 = 0 + 0 - 1 = - 1
y- intercept = - 1 or (0, - 1) in coordinate form
Answer:
Plug x=0 into the equation and solve the resulting equation
The y-intercept:
3x^2 + 2x - 1
3(0)^2 + 2x(0)- 1
0+0-1
-1
y=−1 is intercept for y

angle c = ___ degrees
Angle D = ABC arc / 2
x + 100 = ABC arc / 2
ABC arc = 2 × ( x + 100 )
ABC arc = 2x + 200 ( ♡ )
_________________________________
Angle B = ADC arc / 2
3x = ADC arc / 2
ADC arc = 2 × 3x
ADC arc = 6x ( ☆ )
_________________________________
ABC arc + ADC arc = 360
( ♡ ) , ( ☆ ) :
( 2x + 200 ) + ( 6x ) = 360
8x + 200 = 360
8x = 360 - 200
8x = 160
x = 160/8
x = 20
____________________________
Thus :
Angle A = 5(20) - 3 = 97 degrees
Angle B = 3(20) = 60 degrees
Angle D = 20 + 100 = 120 degrees
____________________________
Sum of the interior angles of any four-sides figures are equal 360 degrees ,
Thus :
Angle A+Angle B+Angle C+Angle D = 360
97 + 60 + Angle C + 120 = 360
Angle C + 120 + 157 = 360
Angle C + 277 = 360
Angle C = 360 - 270 - 7
Angle C = 90 - 7
Angle C = 83 degrees
Need urgent help please, honest answers will get brainliest
Answer: Refer to the screenshot below
I've filled in the boxes with the proper answers
====================================================
Explanation for problem 1
In line 1, I used the distributive rule a*(b+c) = a*b+a*c. On the left side the 3(n+2) becomes 3n+6. On the right side, the 9(6-n) becomes 54-9n
On the next line, I added 9n to both sides. The 3n on the left side updates to 3n+9n = 12n.
For the third line, I subtracted 6 from both sides. Then the last line involves dividing both sides by 12 to fully isolate n. To confirm the solution n = 4, plug it back into the original equation. You should get the same thing on both sides after simplifying.
------------------------------------
Explanation for problem 2
The steps here are similar as problem 1, but this time we're involving fractions. Unfortunately, these steps don't involve clearing out the fractions which is often a handy trick to use.
We use the distributive rule on line 1
For line 2, we subtract 2m/9 from both sides. Think of 2m/3 as 6m/9 to help combine the fractions. The denominators must be the same for you to be able to add or subtract fractions.
For line 3, we subtract 4/3 from both sides. Think of 4/3 as 12/9.
The last step is to multiply both sides by 9/4, which is the reciprocal of 4/9. Your teacher made a typo on the right hand side of the last line. It should read [tex]\frac{4}{9}m[/tex] and not [tex]\frac{2}{9}m[/tex]. Refer to the previous line.

then which set below represents the range of the function?
(Please help)
Answer:
The range is {7, 11, 15, 19}
Step-by-step explanation:
Substitute the domain values in the formula
2x + 1
2(3) + 1 = 7
2(5) + 1 = 11
2(7) + 1 = 15
2(9) + 1 = 19

Assume that y varies inversely with x. If y = 4 when x = 6, find y when x = 2
Answer:
y = 12
Step-by-step explanation:
Given y varies inversely with x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition y = 4 when x = 6, then
4 = [tex]\frac{k}{6}[/tex] ( multiply both sides by 6 )
24 = k
y = [tex]\frac{24}{x}[/tex] ← equation of variation
When x = 2 , then
y = [tex]\frac{24}{2}[/tex] = 12

Hope it is helpful....Uhm can you answer it and tell me how you did it? I'm like dead confused
Answer:
Hello! answer:
rectangle a: 8
rectangle b: 24
figure: 32
Step-by-step explanation:
Hello I'll show a demonstration, with a picture and explanation. Ok so as shown in the picture i circled the base and height those are basically what you have to multiply to find the area.
we are given the height for rectangle a but not the base so we have to find it we know the base at the bottom for the whole thing is 5 and the base for B is. 3 so we can just subtract 3 from 5 to find A's base so... 5 - 3 = 2
now we have everything we need to find the area so....
4 × 2 = 8 so rectangle a is 8
3 × 8 = 24 so rectangle b is 24
then for the whole figure we can just add those two up for the entire area so...
24 + 8 = 32 therefore the figures area is 32 Hope that helps!

there are 2 ways to solve this promblem
one count on your toes and hands by 5 starting at one until u get to 10 fingers and 5 toes. soon the promblems will get harder and you cant do that
other way multiply 5 by 15 and add it to 1
t( 15 ) = t( 1 ) + [ 14 × ( Constant value ) ]
________________________________
t( 1 ) = 1
&
Constant value = t( 2 ) - t( 1 ) = t( 3 ) - t( 2 )
Constant value = 6 - 1
Constant value = 5
________________________________
Thus :
t ( 15 ) = 1 + [ 14 × 5 ]
t( 15 ) = 1 + 70
t( 15 ) = 71
hey guys i have everything caught up but in science i have a 96 but a missing project. projects a worth 80 percent of your grade will i still pass? today’s the last day
Answer:
No
Step-by-step explanation:
Technically, if you didn't turn anything in then no. If it is truly 80% of your final grade then not turning anything in would drop your grade to an F immediately. Although for a single project to be worth 80% of the entire year's grade seems off. Usually, finals and projects are a large percentage, but are more around the 25% range and not 80%. Otherwise, a student could not do anything the entire year and simply do the project and still pass with a B. That is why the grading system is not usually designed like this.
