She earns 32.40 for working 4 hrs.....32.40/4 = 8.10 per hr
y = 8.10h...where y is the amount of money earned and h is the number of hrs worked
Answer: D
Step-by-step explanation:
<u><em>When a coordinate is reflected over the y-axis, it changes from (x, y) to (-x, y)</em></u>
<em>The three coordinates of ΔCDE are</em>
- C = (-8, -1)
- D = (-6, -5)
- E = (-2, -4)
<em>After the y-axis reflection, they'll become:</em>
- C' = (-(-8), -1) = (8, -1)
- D' = (-(-6), -5) = (6, -5)
- E' = (-(-2), -4) = (2, -4)
<em>I hope this is correct :\</em>
Step-by-step explanation:
A
because degree is power.. so the expression with power of 8 is A
for B, the power is 6
for C the power is 9
and D the power is 2
Answer:
no
Step-by-step explanation:
y = 2x
Substitute the points into the equation
3 = 2(6)
3 = 12
This is false
The point does not make the equation true
Answer:
f⁻¹(x) = 
+ 7
Step-by-step explanation:
The inverse of a function reverses the operations performed by the function in the question such if f(x) = y, then we have, f⁻¹(y) = x, which reverses the operation of the first function.
The inverse of a function f(x) = 4·㏒₂(x - 7) is found as follows;
We have;
y = 4·㏒₂(x - 7)
We substitute x for y to get;
x = 4·㏒₂(y - 7) which gives;
x/4 = ㏒₂(y - 7)
= y - 7
y = + 7
Therefore;
f⁻¹(x) = + 7.
