Answer:

5x - 2y = -2

Step-by-step explanation:

Slope: 5/2 and (-2,-4)

y-intercept= -4-(5/2)(-2) = 1

y = 5/2x+ 1

5/2x - y = - 1

2(5/2x - y) = -1*2

5x - 2y = - 2

If f^-1(x) is the inverse of f(x), which statement must be true?
k0ka [10]
F(f-1x)   will be equal to x

take a simple example 

f(x) = 2x

so x = f(x) / 2

 f-1(x) = x/2

f(f-1x) =  2 ( x/2)  = 2 * x/2 = x

Family has an annual income of ​$23 comma 400. Of​ this, one fourth
denis23 [38]

Amount spent for food = $5850, housing = $4680, clothing = $2340, savings = $2600, taxes = $5850, expenses = $2080.

<u>Step-by-step explanation:</u>

Step 1:

Given details are Total Income = $23,400

Step 2:

Amount spent for food, F= 1/4th of 23,400 = 1/4 \times 23400

= $5850

Step 3:

Amount spent for housing, H = 1/5th of 23,400 = 1/5 \times23400

= $4680

Step 4:

Amount spent for clothing, C = 1/10th of 23,400 = 1/10 \times 23400 = $2340

Step 5:

Amount spent for savings, S = 1/9th of 13,400 = 1/9\times 23400 = $2600

Step 6:

Amount spent for taxes, T = 1/4th of 23,400 =  1/4 \times 23400 =$5850

Step 7:

Find amount spent on other expenses by totaling all expenditures and subtracting from the annual income.

Annual Income = F + H + C + S + T + E

Amount spent on other expenses, E = 23400 - (5850 + 4680 + 2340 + 2600 + 5850)

E = 23400 - 21320

E = $2080
