I believe the answer is D. 18
Answer: x = -5
Step-by-step explanation:
-8 (x + 5) = -3x - 7 + x - 3
First, we use distributive property
-8x - 40 = -3x - 7 + x - 3
Then, we combine like terms.
-3x + x = -2x
-7 + -3 = -10
-8x - 40 = -2x - 10
Add 10 to each side
-8x - 30 = -2x
Add 8x to each side
-30 = 6x
Divide each side by 6
-5 = x
Answer:
y = -2x + 6 and y = 1/3x - 7
Step-by-step explanation:
For A, using rise over run, you can count 2 units up and 1 unit left of any given point to get to the next point. Because left is the negative direction on a graph, the 1 unit is negative. To calculate slope, divide the rise (2) over the run (-1) and substitute the slope as m into y = mx + b. In the formula, b is the y-intercept (where the line crosses the x axis). The y-intercept of A is 6, so replace b in the formula with 6:
y = -2x + 6
The slope of B is 1/3 and the y intercept is -7, so substitute those values into the formula again to get the answer for B:
y = 1/3x - 7
Let, the width = x
length = 2x - 4
Perimeter = 2(l+w)
Substitute their values,
72 = 2(x+2x-4)
72 = 2(3x-4)
6x - 8 = 72
6x = 80
x = 80/6
x = 13.3
In short, Your Answer would be 13.33 cm
Hope this helps!
