Y - y₁ = m(x - x₁)
y - 3 = -2¹/₄(x - 4)
y - 3 = -2¹/₄(x) + 2¹/₄(4)
y - 3 = -2¹/₄x - 9
+ 3 + 3
y = -2¹/₄x - 6
Answer:
the number would be 11
Step-by-step explanation:
8 · x - 3 = 64
________ _ (divide both sides by 8)
8 8
x - 3 = 8
+ 3 + 3
x = 11
(check:
11 - 3 = 8
8 x 8 = 64 )
Answer:
(4x+3)^2 = 18
16x+9=18
16x=9
<u>x=9/16</u>
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
h(t) = (t + 3)² + 5, -5 ≤ t ≤ -1
The average rate of change is the change in h over the change in t.
(h(-1) − h(-5)) / (-1 − (-5))
= ((-1 + 3)² + 5 − ((-5 + 3)² + 5)) / (-1 + 5)
= (4 + 5 − 4 − 5)) / 4
= 0
