Answer:
S(0, 2)
Step-by-step explanation:
Midpoint Formula: ![(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )](https://tex.z-dn.net/?f=%28%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%20%2C%5Cfrac%7By_1%2By_2%7D%7B2%7D%20%29)
Step 1: Plug in known variables
5 = (10 + x)/2
-8 = (18 + y)/2
Step 2: Solve
10 = 10 + x
x = 0
-16 = 18 + y
y = 2
Step 3: Write coordinates
(0, 2)
Answer:
y = 16
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 48 when x = 6, thus
k =
=
= 8
y = 8x ← equation of variation
When x = 2, then
y = 8 × 2 = 16
Answer: 15 + 2x
Step-by-step explanation:
5b + 2x
5 (3) + 2x
15 + 2x
I think I'm right so I hope it helped!!
Step-by-step explanation:
If x + 7 is a factor of f(x), then f(-7) = 0.
f(-7) = (-7)³ − 3(-7)² + 2(-7) − 8
f(-7) = -343 − 147 − 14 − 8
f(-7) = -512
x + 7 is not a factor of f(x).
Answer:
48 Greater than the sum
