Answer:
Step-by-step explanation:
Given
Required
Find AC
ABC XYZ
To solve AC, we make use of the following equivalent ratios.
This gives:
Express as fraction
Cross multiply
Solve for AC
Simplify :
12+-5x+6x=4
combine like terms :
-5x+6x=1x
12+1x=4
solving :
12+1x=4
solving for variable ‘x’
move all terms containing x to the left, all other terms to the right, add ‘-12’ to each side of the equation
12+-12+1x=4+-12
combine like terms:
then divide each side
your answer : x=-8
filling, three-dimensional, unit squares
I hope this helps ^^

Answer: Choice C: {-2, -1, 0, 3, 4}
----------------------------
Work Shown:
Plug y = -13 into the equation and solve for x
y = 5*x - 3
-13 = 5*x - 3
-13 + 3 = 5*x - 3 + 3
-10 = 5*x
5*x = -10
5*x/5 = -10/5
x = -2
------------------------------
Plug y = -8 into the equation and solve for x
y = 5*x - 3
-8 = 5*x - 3
-8 + 3 = 5*x - 3 + 3
-5 = 5*x
5*x = -5
5*x/5 = -5/5
x = -1
------------------------------
Plug y = -3 into the equation and solve for x
y = 5*x - 3
-3 = 5*x - 3
-3 + 3 = 5*x - 3 + 3
0 = 5*x
5*x = 0
5*x/5 = 0/5
x = 0
------------------------------
Plug y = 12 into the equation and solve for x
y = 5*x - 3
12 = 5*x - 3
12 + 3 = 5*x - 3 + 3
15 = 5*x
5*x = 15
5*x/5 = 15/5
x = 3
------------------------------
Plug y = 17 into the equation and solve for x
y = 5*x - 3
17 = 5*x - 3
17 + 3 = 5*x - 3 + 3
20 = 5*x
5*x = 20
5*x/5 = 20/5
x = 4
------------------------------
The domain is the set of x value results we got, so the domain is {-2, -1, 0, 3, 4}
