Jessica is selling books during the summer to earn money for college. She
earns a commission on each sale but has to pay for her own expenses.
After a month of driving from neighborhood to neighborhood and walking
door-to-door, she figures out that her weekly earnings are approximately a
linear function of the number of doors she knocks on.
She writes the equation of the function like this: E(x) = 10x - 30, where x is the
number of doors she knocks on during the week and E(x) is her earnings for
the week in dollars.
Which of the following are reasonable interpretations of the y-intercept of
Jessica's function?
Check all that apply.
A. She can earn $10 per week even if she does not knock on any
doors
B. Her expenses are $30 per week.
c. If she does not knock on any doors at all during the week, she will
lose $30
D. She will lose $10 per week if she does not knock on any doors.

what does 45=-3x tell me
Answers
Answer: x = -15
Hope this helps :)
Answer:
x = -15
Step-by-step explanation:
[One step multiplication problem]
When solving a one-step multiplication problem the easiest thing to do would be to divide the 'answer' (in this case, 45) by the coefficient (in this case, -3). A negative number times a negative number is a positive number, so x would be a negative number. 45 divided by -3 is -15.
So, x = 15.

Solve the proportion 40/z+1 = 15/6
Answers
Answer:
z = 15Step-by-step explanation:
[tex] \frac{40}{z + 1} = \frac{15}{6} \\ [/tex]
Cross multiply
That's
[tex]15(z + 1) = 40(6) \\ 15z + 15 = 240[/tex]
Send 15 to the right side of the equation
[tex]15z = 240 - 15 \\ 15z = 225[/tex]
Divide both sides by 15
[tex] \frac{15z}{15} = \frac{225}{15} \\ [/tex]
We have the final answer as
z = 15Hope this helps you

A = [tex]\frac{h}{2} (a + b)[/tex]
First off, we need to multiply both sides by [tex]\frac{2}{h}[/tex] to cancel out the [tex]\frac{h}{2}[/tex].
[tex]\frac{2A}{h}[/tex] = a + b
Now, we need to subtract b from both sides.
