<span>f(x)=4x²-15x-25
</span><span>f(x)=(4x + 5)(x - 5)

</span><span>zero-product property 
let </span>f(x)=(4x + 5)(x - 5) = 0
so
(4x + 5)(x - 5) = 0
4x +5 = 0
4x = -5
  x = -5/4
  x = -1.25

x - 5 =0
x = 5

answer
factor: (4x + 5)(x - 5)
x = 5 and x = -1.25

Given that 2(-x + 4)=3 prove that x=5/2
user100 [1]

Answer:

x = 5/2

Step-by-step explanation:

So firstly, you want to distribute. It'll make your life much easier.

-2x + 8 = 3

-2x = -5 (subtracting 8 from both sides)

x = 5/2 (dividing both sides by -2 to obtain x)

Hope this helps :)

A sofa is on sale for 73% off. The sale price is $172.80. What is the regular price?
Lapatulllka [165]
To get the answer you have to divide the sale price $172.80 by 73%.
So first you turn 73% into a decimal by moving the decimal two places to the left turning it into .73 

$172.80 divided by .73 = $236.71

You can check by then multiplying $236.71 with .73

Consider the following figure:
Solnce55 [7]

Answer:

x=90

y=148

Step-by-step explanation:

Since we know a line is 180 degrees, and we know that angle Q is 90, x must be a 90-degree angle as well.

With our given information we can add up the two given angles in the triangle which are 90 and 58

90+58=148

To find what R is, we must subtract 148 from 180 because all the angles in a triangle sum up to 180.

180-148=32

Now that we know that R is 32, because we know that a line is 180 degrees, we can subtract 32 from 180 to get our final answer for y as 148.

180-32=148
