X^2 - 3x + 2 =
(x - 1)(x - 2) <==
Answer: x=90
Step-by-step explanation: Okay let's see! Let's solve your equation step-by-step.
x
42
=
15
7
Step 1: Cross-multiply.
x
42
=
15
7
x*(7)=(15)*(42)
7x=630
Step 2: Divide both sides by 7.
7x
7
=
630
7
x=90
Answer:
the answer is bc you go over negative two and up five (-2,5)
3x + 4y = 5
2x - 5y = 8
To answer this question, we need to put both of these equations into Slope-Intercept form, or in other words, solve for y.
3x + 4y = 5 Subtract 3x from both sides
4y = -3x + 5 Divide both sides by 4
y =
![-\frac{3}{4}](https://tex.z-dn.net/?f=%20-%5Cfrac%7B3%7D%7B4%7D%20)
+
![\frac{5}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B4%7D%20)
2x - 5y = 8 Subtract 2x from both sides
-5y = -2x + 8 Divide both sides by -5
y =
![\frac{2}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B5%7D%20)
-
![\frac{8}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%7D%7B5%7D%20)
When you look at the two equations, you can see that their slopes are completely different, so they aren't parallel, or inconsistent. Since
![\frac{2}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B5%7D%20)
is not the same as<span>
![-\frac{3}{4}](https://tex.z-dn.net/?f=%20-%5Cfrac%7B3%7D%7B4%7D%20)
, they aren't the same line, or dependent. So, the only option left is that they are
consistent and independent.</span>
It's simple, just add 124 to 11. 124 + 11 = 135 degrees.
