=-6
Answer is -6
Answer:
This product is 6.2(3c + 8)
Step-by-step explanation:
This product is 6.2(3c + 8). The factors are 6 and (3c + 8).
Answer:
A. y=-2x + 8
Step-by-step explanation:
The slope-intercept formula is written as y=mx+b, where m is the slope and b is the y-intercept.
b can be easily found on the graph, as the point (0,8) is where the line crosses the y-axis, so b=8.
The slope can be found using the slope formula:
![\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
We can take either points as the first, and we'll reach this result.
![\frac{-4-8}{6-0} = \frac{-12}{6} = \frac{-2}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B-4-8%7D%7B6-0%7D%20%3D%20%5Cfrac%7B-12%7D%7B6%7D%20%3D%20%5Cfrac%7B-2%7D%7B1%7D)
This means that the slope is -2 and the y-intercept is 8
So the final equation is choice (a.)
Answer:
6
Step-by-step explanation:
24 = 2L + 2(6), multiply...
24 = 2L + 12, subtract 12 to both sides...
12 = 2L, divide 2 to both sides to isolate the varibale L
6 = L
Therefroe, L = 6
We use solid boundary lines when we have
![\geq](https://tex.z-dn.net/?f=%20%5Cgeq%20)
or
![\leq](https://tex.z-dn.net/?f=%20%5Cleq%20)
.
Final answer: <span>d. x − y ≤ 5</span>
