2
Step-by-step explanation:
If you square -4 it equals 16 and if you take that number and divibe it by 8 you get 2.
Answer:
37.7 ft²
Step-by-step explanation:
2×3.14×r=30.77
<em>Divide both sides by 2</em>
3.14×r=15.385
<em>Divide both sides by 3.14</em>
r≈4.9
3.14×r²
3.14×4.9²=
24.01×3.14≈
75.4
75.4÷2=
37.7
Answer:
(2b+3) (b+7)
Step-by-step explanation:
2b²+17b+21
2b²+14b+3b+21
2b(b+7) + 3(b+7)
(2b+3) (b+7)
You can take any 2 points from the table and calculate the slope, as follows:
-2-(-4) 2
m = slope = ---------- = ------ = -1/5
-5 - 5 -10
The slope-intercept form is y = mx + b. You already know m (which is -1/5), and have several points from which to choose to obtain x and y. Let's use the given point (-2, -1).
Then -1 = (-1/5)(-2) + b, or -1 = 2/5 + b. Solve for b.
-5 = 2 + 5b, so 5b = -7, and b = -7/5.
The desired equation is y = (-1/5)x - 7/5.
