Answer:
Slope of the line that passes through the points (1, 7) and (3, 3) = -2
Step-by-step explanation:
Given in the question two co-ordinates,
(1, 7)
(3, 3)
here x1 = 1
x2 = 3
y1 = 7
y2 = 3
Formula to use
m = ![\frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D)
= ![\frac{3-7}{3-1}](https://tex.z-dn.net/?f=%5Cfrac%7B3-7%7D%7B3-1%7D)
= -4/2
= -2
Plug in -2 for x.
f(-2) = 2(-2)^3 - 4(-2)
f(-2) = 2(8) + 8
f(-2) = 16 + 8
f(-2) = 24
Answer:
1,3,5,6
Step-by-step explanation:
Answer:
b = 17.55
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + b^2 = 18^2
16 + b^2 = 324
<u>-16 -16</u>
b^2 = 308
square root them
<u>b = 17.55</u>
let me know if it is correct!
