f(x) = 10x + 2
f(2) = 10(2) + 2
Simplify the parentheses by multiplying.
f(2) = 20 + 2
Add.
f(2) = 22

If one of the roots of the equation x²- 4x + k=0exceeds the other by 2, then find the roots and determine the value of k
Answers
Answer:
roots: 1 and 3
k = 3
Step-by-step explanation:
2 roots: p and p+2
(x-p) (x-p-2) = x² - 4x + k
x² -2px -2x + p² + 2p = x² - 2 (p+1)x + (p² + 2p) = x² -4x + k
-2 (p+1) = -4
p+1 = 2
p = 1 ... root 1
p' = 1+2 = 3 ... root 2
k = p² + 2p = 3
check: (x-1) (x-3) = x² - 4x + 3 = x² - 4x + k

pls help?
Answers
Answer:
X = -4
Step-by-step explanation:
91x + 637 =273
First subtract 637 from both sides: 91x = -364
Then, divide both sides by 91 to get X by itself: X = -4
Answer: -4
91x= 273- 637
91x= -364
X= -364/91
X= -4
