eplace f(x) with y

swtich x and y

solve for y

replace y with f⁻¹(x)

f(x)=4x+8

y=4x+8

x=4y+8

x-8=4y

1/4x-2=y

y=1/4x-2

f⁻¹(x)=1/4x-2

none of the above

Drake wants to save $750 so that he can take a class on computer analysis for cars. The class is being held on various dates ove
STatiana [176]
C. Both options A and B will allow him to meet his goal.



Looking at Drake's situation after 4 weeks, he only has $470 saved. By his original plan, he should have had $500 saved. So he's $30 short of his goal and has 2 weeks until his originally planned class. If he goes with option A and takes the later class, he will save an additional $125 which is more than enough to make up the $30 short fall. So option A will work for him to save enough money for his class. With option B, he will save $140 for the last 2 weeks of his plan giving him a savings of $280 for the last 2 weeks. Adding the $470 he's already saved will give him a total savings of $470 + $280 = $750 which is enough for him to attend his class. So option B will also allow Drake to attend his desired class. Both options A and B allow him to meet his goal. Hence, the answer is "c".

Pls answer if u know :) <br><br> This is a very important homework and i was gone for days so idk
aliya0001 [1]

Answer:

Option B

Step-by-step explanation:

Slope of the line is calculated by the formula:

m=\frac{y_2-y_1}{x_2-x_1}\\\\

We have the points ( -2 , 4) and (3 , -5) so plug in the values in the formula:

m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{-5-4}{3-(-2)}\\\\m=\frac{-9}{5}\\

so the slope(m) equals -9/5
