Answer:
C. y = 2 (x + 3)³ − 4
Step-by-step explanation:
y = x³
Stretch vertically by 2.
y = 2x³
Shift horizontally 3 units to the left.
y = 2 (x + 3)³
Shift vertically 4 units down.
y = 2 (x + 3)³ − 4
Option C:
Solution:
Given expression is
Note:
To find the correct expression for the above simplified expression.
Option A:
5 can be written as .
It is not the given simplified expression.
Option B:
Cancel the common factor in both numerator and denominator.
It is not the given simplified expression.
Option C:
Cancel the common factor in both numerator and denominator.
It is the given simplified expression.
Option D:
It is not the given simplified expression.
Hence Option C is the correct answer.
Answer:
Option B. 7.6
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
where
k is the constant of proportionality
The slope of the linear equation is the same that the constant of proportionality
In this problem we have
so
the slope is
therefore
The constant of proportionality k is
Y = 1.55x + 3.70
1.55 x 150 = 232.5
232.5 + 3.70 = 236.2
The answer is C 236.20 hope that helped.
