Answer:
See below.
Step-by-step explanation:
Multiplying terms with exponents make the exponents add together.
13.) x² · x⁵ = x⁷
14.) b⁵ · b³ = b⁸
15.) y⁴ · y⁷ = y¹¹
16.) m⁴ · m¹ = m⁵
Answer:
D
Step-by-step explanation:
If f(x) = 4x ^ 2 - 3 and g(x) = x + 1 , find (f - g)(x)
A. 4x ^ 2 - x - 2
B. x - 4x ^ 2 - 2
C. 4x ^ 3 - 3
D. 4x ^ 2 - x - 4
(f - g)(x) = f(x) - g(x)
4x ^ 2 - 3 - (x + 1 ) Multiply the brackets by the negative.
4x ^ 2 - 3 -x - 1 Add like terms.
4x ^ 2 - x - 4 Final Answer
Answer:
y=70x+12
Step-by-step explanation:
y= amount of total money spent
x= amount of hours
%increase = (increase / original number ) x100
increase = 3,24 - 2?85 = 0,39
