<h3><u>(2x - 5)(4x - 3)</u></h3>
The AC method, also known as splitting the middle, can be shown like this:
8x^2 - 26x + 15
<em><u>Check factors of 120.</u></em>
1 * 120
-1 * -120
2 * 60
-2 * -60
3 * 40
-3 * -40
5 * 24
-5 * -24
6 * 20
-6 * -20 (these factors, when added together, are equal to the middle term, and thus splitting the middle term is possible.)
<em><u>Split the middle term.</u></em>
8x^2 - 6x - 20x + 15
<em><u>Group in terms of 2.</u></em>
(8x^2 - 6x) - (20x + 15)
<em><u>Factor each binomial.</u></em>
2x(4x - 3) - 5(4x - 3)
<em><u>Rearrange the terms.</u></em>
(2x - 5)(4x - 3)
Well what you want is y = mx + b
m = slope
b = intercept for y
with that just substitute in the slope and the intercept, but leave the x and y as it is. So later on you can put in a x coordinate and get the y coordinate through that, hope this helps!
Answer:
a. y= 4 + 0.50x b. y= 1.00x

Answer:
9 cm
Step-by-step explanation:
![\sqrt{117} ^{2} - 6^{2} = x^{2}](https://tex.z-dn.net/?f=%5Csqrt%7B117%7D%20%5E%7B2%7D%20-%206%5E%7B2%7D%20%20%3D%20x%5E%7B2%7D)
![81 =x^{2}](https://tex.z-dn.net/?f=81%20%3Dx%5E%7B2%7D)
![\sqrt{81} = x](https://tex.z-dn.net/?f=%5Csqrt%7B81%7D%20%3D%20x)
9 cm = x
