Answer:
49
Step-by-step explanation:
Root is the opposite of a power of 2.
Find 7 to the power of 2 to find the number inside:

Answer:
(x + 2) is a factor of f(x)
Step-by-step explanation:
Using the remainder theorem to divide f(x) by (x - h)
Evaluate f(h) and if equal to 0 then (x - h) is a factor
f(- 3) = (- 3)³ - 7(- 3)² + 36 = - 27 - 63 + 36 ≠ 0
f(- 2) = (- 2)³ - 7(- 2)² + 36 = - 8 - 28 + 36 = 0
f(- 6) = (- 6)³ - 7(- 6)² + 36 = - 216 - 252 + 36 ≠ 0
f(2) = 2³ - 7(2)² + 36 = 8 - 28 + 36 = 16 ≠ 0
Hence (x + 2) is a factor of f(x)
Answer:
The slope is 1.
Step-by-step explanation:
Remember:
![m = \frac{y_2 - y_1 }{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%20y_1%20%7D%7Bx_2%20-%20x_1%7D)
Let's plug in!
![m = \frac{ 9 - 4}{4 - ( -1)} = \frac{ 5}{ 5} = 1](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B%209%20-%204%7D%7B4%20-%20%28%20-1%29%7D%20%3D%20%5Cfrac%7B%205%7D%7B%205%7D%20%3D%201)
The 3 is distributed to the a+b inside the brackets........
