Step-by-step explanation:

Step 1: Define

Identify

y = -23(x + 9) + 4

y = 0

Step 2: Solve for x

Substitute in y: 0 = -23(x + 9) + 4
[Subtraction Property of Equality] Subtract 4 on both sides: -4 = -23(x + 9)
[Division Property of Equality] Divide -23 on both sides: 4/23 = x + 9
[Subtraction Property of Equality] Subtract 9 on both sides: -203/23 = x
Rewrite: x = -203/23

To do these, always convert the percents to decimals, so you can subtract it from 1. Remember, 1 is the whole. When you subtract the part that's taken off, you are left with what you have to pay. If you have 20% off of $100, then you are paying for 80% of $100. **of means to multiply** so you would multiply: 0.8X100, which would be $80.

First, multiply 125x0.8

Multiply that answer by 0.7

You should get B. $70

3) multiple 22.90x0.93

You should get D

X2 + 3x - 108 = 0 What is the answer?

worty [1.4K]

Answer:

The answer is x=9 and/or x = -12

Step-by-step explanation:

This is a quadratic formula meaning that you must take the a value (1) b value (3) and the c value (108) and plug it into the quadratic formula.

$\frac{-3±\sqrt{9+4*1*-108} }{2}$

which simplifies to -3 add or subtract the sqrt of 441 divided by two.
