Answer:

(22, 5)

Step-by-step explanation:

Given the 2 equations

x = y + 17 → (1)

x = 4y + 2 → (2)

Substitute x = 4y + 2 into (1)

4y + 2 = y + 17 ( subtract y from both sides )

3y + 2 = 17 ( subtract 2 from both sides )

3y = 15 ( divide both sides by 3 )

y = 5

Substitute y = 5 into either (1) or (2) and solve for x

(1) : x = 5 + 17 = 22

Solution is (22, 5)

A family uses 1,303 kWh of electric energy in a month. If the power company charges $0.08 per kilowatt hour, what is the total e

prisoha [69]

The total electric energy bill for the month is $\$104.24$

Solution: 

Given that

Electric energy consumed by family in a month = 1303 kWh

Power Company charges $\$0.08$ per kilowatt hour

Need to calculate total electric energy bill for the month.

Price of 1 kilowatt hour = $\$0.08$

$\text { Price of } 1303 \text { kilowatt hour }=1303 \text { x Price of } 1 \text { kilowatt hour }=1303 \times 0.08=\$ 104.24$

Total electric energy bill for the month = Price of Electric energy consumed by family in a month = Price of 1303 kilowatt hour = $\$104.24$

Y=2x-4 What is the five ordered pairs and completing the input/output table

kati45 [8]

Answer:

{(0, -4), (1, -2), (2, 0), (3, 2), (4, 4)}

Input values (x) = {0, 1, 2, 3, 4}

Output values (y) = {-4, -2, 0, 2, 4}

Step-by-step explanation:

Given the linear equation, y = 2x - 4, you could practically choose any input value (for x), to have an output value (for y).

If x = 0:

y = 2(0) - 4

y = 0 - 4

y = -4

First ordered pair: y-intercept = (0, -4)

If x = 1:

y = 2(1) - 4

y= 2 - 4

y = -2

Second ordered pair: (1, -2).

If x = 2:

y = 2(2) - 4

y= 4 - 4

y = 0

Third ordered pair: x-intercept = (2, 0).

If x = 3:

y = 2(3) - 4

y = 6 - 4

y = 2

Fourth ordered pair: (3, 2).

If x = 4:

y = 2(4) - 4

y = 8 - 4

y = 4

Fifth ordered pair: (4, 4).

Your input values (x) = {0, 1, 2, 3, 4}

Your output values (y) = {-4, -2, 0, 2, 4}
