D. Ten and eight tenths
Step-by-step explanation:
5.4*2
= 10.8
Answer:
10x - 13.
Step-by-step explanation:
−3(6x+ 7) + 4(7x + 2)
= -18x - 21 + 28x + 8
= 10x - 13.
We need to find m and b to find in the equation of a line:
y = mx + b
↑ <span>↑
slope y-intercept
To find m, the slope, we need to find the rise over the run of the line. You pick two points and use the y values finding the difference of them and do the same for the x values and put them on the bottom. Let's use the points (0, -2) and (4, 0):
</span>↑ ↑<span>
(x₁, y₁) (x₂, y₂)
m = (y</span>₂ - y₁)/(x₂ - x₁)
m = (-2 - 0)/(0 - 4)
m = (-2)/(-4)
m = 1/2
The slope is positive since the line is going upward from left to right.
Now we need b, the y intercept, where the line intersects with the y axis, simply by looking at the graph. b is -2.
Thus, the answer is C. y = 1/2x - 2.
Firstly, round 63 and you get 60, then, round 42 and you get 40. Finally, add 60 and 40. Your answer will be 100.
