Graph the line with slope
1/2 and y-intercept -9
Answer:
Step-by-step explanation:
slope is the x axis and y intercept is the y axis
so 1/2 will go on the x axis and -9 will go on the y axis
1/2 uses the rise over run method
Answer:
Answer is in the screenshot. The equation for the line is y=1/2 x - 9
Step-by-step explanation:
To graph a line when you know the slope and y intercept, you make a point on the y intercept. Your y intercept iIs -9 so you would make a point on (0,-9).
After you have the point on (0,-9) you use the slope to create the rest of your line. Slope is just Rise
Run
Your slope is 1/2. That means your next point on the line is up 1 unit and right 2 units. The next point on the line is (2,-8).

2r+8-r=-7 solve the equation
Answer:
r = -15
Step-by-step explanation:
2r + 8 - r = -7
~Combine like terms
r + 8 = -7
~Subtract 8 to both sides
r = -15
Best of Luck!
Answer:
hii
Step-by-step explanation:
Group Like Terms
2r-r+8=-7
Add smiliar elements
r+8=-7
Subtract 8 form both sides
r+8-8=-7-8

B jada writes this equation for the sum of the ages (x)+(x+3) +3(x+3)-1=87 explain the meaning of the variable and each term of the equation.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
[tex](x)+(x+3) +3(x+3)-1=87[/tex]
simplifying the equation
[tex]x+x+3+3x+9-1=87[/tex]
adding similar elements
[tex](x+x+3x)+(3+9-1-87)=0[/tex]
[tex]5x-76=0[/tex]
Thus, the equation is a linear equation in one variable 'x'.
A term is a single mathematical expression, so the simplified expression has two terms which are:
5x-76The term 5x has the variable 'x' of power 1.
The term -76 does not involve any variable, Hence, -76 is a constant term.

The domain of 0 ≤ x ≤ 6 is x ∈ [0, 1, 2, 3, 4, 5, 6], and the range of the 0 ≤ y ≤ 6 is y ∈ [0, 1, 2, 3, 4, 5, 6].
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
0 ≤ y ≤ 72
The range will be y ∈ [0, 72]
0 ≤ x ≤ 72
The domain will be x ∈ [0, 72]
0 ≤ x ≤ 6
The domain will be x ∈ [0, 1, 2, 3, 4, 5, 6]
0 ≤ y ≤ 6
The range will be y ∈ [0, 1, 2, 3, 4, 5, 6]
Thus, the domain of 0 ≤ x ≤ 6 is x ∈ [0, 1, 2, 3, 4, 5, 6], and the range of the 0 ≤ y ≤ 6 is y ∈ [0, 1, 2, 3, 4, 5, 6].

In a scale drawing of a house, 2 inches : 5 feet. The actual kitchen of the house will be 17 feet long. How long will the drawing of the kitchen be?
A. 5.2
B. 6.8
C. 7.5
D. 8
Answer:
B, 6.8
Step-by-step explanation:
Let's first find how many feet it is per 1 inch. We can do this by dividing 5 by 2
5/2= 2.5
Now it is 1 inch : 2.5 feet
17/2.5 = 6.8
1 x 6.8 = 6.8
6.8 inches : 17 feet
You could also solve this by doing
17/5 =3.4
3.4 x 2 = 6.8
6.8 inches : 17 feet

hi its me addison ray
Nicholas has 22 nickels, dimes, and quarters. There are 3
less dimes than quarters and 2 more dimes than nickels.
How much money does he have?
Nickels: 22
Dimes: 24
Quarters: 27
2 more dimes than nickels, we already know that there are 22 nickles so...
Dimes= 24
3 less dimes that quarters ^(we already know how many dimes).
All we have to do is add 3 to the amount of dimes!
Quarters 27
____________________________________________________________
Now to find the amount of money you have to find out what each coin equals and multiply the number of coins by the cost of each coin, and then by 100 because there are 100 cents in 1 dollar.
22 nickels*5/100= $1.10
24 dimes*10/100= $2.40
27 quarters*25/100= $6.75
1.10+2.40+6.75= $10.25
The amount of money he has in $10.25
A: x = 3

If the sides to a triangle are 20, 40, and 80 cem, is it Right triangle?
Answer: no
because using Pytago theorem, we have:
20² + 40² ≠ 80²
80² + 20² ≠ 40²
80² + 40 ² ≠ 20²
Step-by-step explanation:
Answer:
No, it does not follow the Pythagorean Theorem.
Step-by-step explanation:
A right triangle must follow the equation a^2 + b^2 = c^2 for its sides to be true. 20^2 + 40^2 = 2000.
the square root of 2000 equals about 44.7213595.
Thus, a triangle with sides 20, 40, and 80 is not a right triangle.

if [tex]f(x)=\frac{1}{2}x-2[/tex] then what is [tex]f^-1(x)[/tex] (the inverse of f(x)? let's find out[tex]f(x)=\frac{1}{2}x-2\\y=\frac{1}{2}x-2[/tex] make f(x) into yThen make y into x and make x into y so [tex]x=\frac{1}{2}y-2[/tex][tex]x=\frac{1}{2}y-2[/tex] now get the new y on the left and everything else on the right[tex]x=\frac{1}{2}y-2\\x+2=\frac{1}{2}y\\2(x+2)=(2)\frac{1}{2}y\\y=2x+4[/tex] now make y = g(x)[tex]g(x)=2x+4[/tex] So you found the inverse of f(x) and it is the same as g(x), so the functions are inverses of each otherFor every 1 litre of water used to make a medicine, 150 ml of sucrose and 600ml of saline solution are used.
