A + b phrase describe the variable expression y + 8
Answer:
Slope = -3
Step-by-step explanation:
8-17/0+3=-9/3=-3 : Slope Formula
Answer:
13-13x
Step-by-step explanation:
3*2=6
(6-5x+6) + (9-8x-8)
Combine Like Terms
(12-5x) + (1-8x)
Put x on one side and numbers on the other.
(12+1) + (-5x+ (-8x))
13-13x
Given the domain {-4, 0, 5}, what is the range for the relation 12x 6y = 24? a. {2, 4, 9} b. {-4, 4, 14} c. {12, 4, -6} d. {-12,
xz_007 [3.2K]
The domain of the function 12x + 6y = 24 exists {-4, 0, 5}, then the range of the function exists {12, 4, -6}.
<h3>How to determine the range of a function?</h3>
Given: 12x + 6y = 24
Here x stands for the input and y stands for the output
Replacing y with f(x)
12x + 6f(x) = 24
6f(x) = 24 - 12x
f(x) = (24 - 12x)/6
Domain = {-4, 0, 5}
Put the elements of the domain, one by one, to estimate the range
f(-4) = (24 - 12((-4))/6
= (72)/6 = 12
f(0) = (24 - 12(0)/6
= (24)/6 = 4
f(5) = (24 - 12(5)/6
= (-36)/6 = -6
The range exists {12, 4, -6}
Therefore, the correct answer is option c. {12, 4, -6}.

Step 1: Find the value of one variable in terms of the other.
![a+3b=7\\a=7-3b](https://tex.z-dn.net/?f=a%2B3b%3D7%5C%5Ca%3D7-3b)
Step 2: Substitute the value you just found for this variable in the other equation.
![3a-2b=8\\3(7-3b)-2b=8\\21-9b-2b=8\\21-11b=8\\21=8+11b\\13=11b\\\frac{13}{11}=b\\ b=1\frac{2}{11}](https://tex.z-dn.net/?f=3a-2b%3D8%5C%5C3%287-3b%29-2b%3D8%5C%5C21-9b-2b%3D8%5C%5C21-11b%3D8%5C%5C21%3D8%2B11b%5C%5C13%3D11b%5C%5C%5Cfrac%7B13%7D%7B11%7D%3Db%5C%5C%20b%3D1%5Cfrac%7B2%7D%7B11%7D)
Step 3: Use your new value for the second variable to find the first.
![a+3b=7\\a+3(1\frac{2}{11})=7\\a+3\frac{6}{11}=7\\\\a=3\frac{5}{11}](https://tex.z-dn.net/?f=a%2B3b%3D7%5C%5Ca%2B3%281%5Cfrac%7B2%7D%7B11%7D%29%3D7%5C%5Ca%2B3%5Cfrac%7B6%7D%7B11%7D%3D7%5C%5C%5C%5Ca%3D3%5Cfrac%7B5%7D%7B11%7D)
Now that we know the values for a and b we can find the value of 4a+b.
