Nancy borrowed $150 from her parents to buy a video game system. She has agreed to pay them back $25 each week Which equation re

Zinaida [17]

Answer:

P = 150 - 25w

Step-by-step explanation:

Amount borrowed = $150

Repayment amount = $25 each week

P = amount Nancy owes

w = number of weeks

Amount Nancy owes = amount borrowed - repayment plan per week

P = 150 - 25w

During the first week of repayment: when w = 1

P = 150 - 25w

P = 150 - 25(1)

= 150 - 25

= 125

P = $125

Solve 2x^2 − 8x = −7

kenny6666 [7]

Answer:

The answer to your question is below

Step-by-step explanation:

2x² - 8x = - 7

Divide by 2

$\frac{2}{2} x^{2} - \frac{8}{2} x = \frac{-7}{2}$

Complete the trinomial

$x^{2} - 4x + (2)^{2} = \frac{-7}{2} + (2)^{2}$

Simplify

$x^{2} - 4x + (2)^{2} = \frac{- 7 + 4}{2}$

$x^{2} - 4x + 4 = \frac{-3}{2}$

Factor

(x - 2)² = $\frac{-3}{2}$

Get the square root

$\sqrt{(x - 2)^{2}} = \sqrt{\frac{-3}{2}}$

Simplification

x - 2 =± $\sqrt{\frac{3}{2}} i$

x₁ = 2 + $\sqrt{\frac{3}{2}} i$

x₂ = 2 - $\sqrt{\frac{3}{2}}$
