Answer:
-129
Step-by-step explanation:
2x+5=0
x=-5/2 [By the remainder theorem]
f(-5/2)=8(-5/2)^3+4(-5/2)^2+13(-5/2)+3
=-125+25-65/2+3
=-129.
Step-by-step explanation:
We have to make x the subject:
y = x² + 4x + 4.
=> y = (x + 2)² by completing the square
=> x + 2 = ±√y
=> x = ±√y - 2
Therefore the inverse is y = ±√x - 2.
Answer:
3x-13
Step-by-step explanation:
2x+x+(-5)
Simplify
SOrry if its wrong :(
The answer is (9y)^5
The first sequence of operation asks you to take the product of 9 and y, which means that they must be multiplied together. Next, you must raise 9y to the fifth power, which means their product has an exponent of 5.
