Answer:

Step-by-step explanation:

58 + (x+9) + (2x-8) = 90

(x+9) + (2x-8) = 32

3x + 1 = 32

3x = 31

x = 31/3

What is the slope intercept equation of the line below

shtirl [24]

Answer:

y = 2x - 3

Step-by-step explanation:

Step 1: Remember the equation

The slope intercept form is y = mx + b where m is the slope and b is the y-intercept

Step 2: Solve

We can see the y-intercept(where the line crosses the y axis) is at y = -3

We know slope is $\frac{rise}{run}$ so we can see for every 1 square it moves right it moves 2 up so the slope would be $\frac{2}{1}$ or 2

Plug what we know into the equation

y=2x-3

Step 3: Therefore Statement

Therefore the equation of the line shown below is y = 2x - 3

Prove that if m + n and n + p are even integers, where m, n, and p are integers, then m + p is even. what kind of proof did you

scoray [572]

Prove that if m + n and n + p are even integers, where m, n, and p are integers, then m + p is even.
m=2k-n, p=2l-n

Let m+n and n+p be even integers, thus m+n=2k and n+p=2l by definition of even
m+p= 2k-n + 2l-n substitution
= 2k+2l-2n
=2 (k+l-n)
=2x, where x=k+l-n ∈Z (integers)
Hence, m+p is even by direct proof.

I forgot how to do this n they didn’t put an example help me lol

lyudmila [28]

Answer:

60 $m^2$

Step-by-step explanation:

First, find the area of the square as it the missing piece wasn't missing.

8 x 9 = 72 $m^2$

Then, find the area of the missing section.

3 x 4 = 12 $m^2$

Finally, subtract 12 $m^2$ from 72 $m^2$ and you get 60 $m^2$
