$2x+4=0\\
y=5-3x\\\\
2x=-4\\
y=5-3x\\\\
x=-2\\
y=5-3x\\\\
y=5-3\cdot(-2)\\
y=5+6\\
y=11\\\\
x=-2,y=11$

how do I do this? I think I solved for z=24 but i'm not totally sure. I'm confused on how to solve for x and y mostly. We are us

The answer would be 21 because its the same length as the other side.

Complete the point-slope equation of the line through ( − 5 , 4 ) (−5,4)left parenthesis, minus, 5, comma, 4, right parenthesis

Tanzania [10]

The point slope form of equation through given points is:

$y-6=\frac{1}{3}(x-1)$

Step-by-step explanation:

Given points are:

(x1,y1) = (-5,4)

(x2,y2) = ((1,6)

First of all we have to find the slope of line

So,

$m=\frac{y_2-y_1}{x_2-x_1}\\=\frac{6-4}{1+5}\\=\frac{2}{6}\\=\frac{1}{3}$

Point-slope form is given by:

$y-y_1=m(x-x_1)$

Putting m=1/3

$y-y_1=\frac{1}{3}(x-x_1)$

Putting (1,6) in the equation

$y-6=\frac{1}{3}(x-1)$

The point slope form of equation through given points is:

$y-6=\frac{1}{3}(x-1)$

On Wednesday, a local hamburger shop sold a combined total of 512 hamburgers and cheeseburgers. The number of

Mazyrski [523]

Hey there! I'm happy to help!

Let's call our hamburgers h and our cheeseburgers c and set up a system of equations to solve.

c+h=512

c=3h

Let's plug this value of c into the first equation to solve for h.

3h+h=512

4h=512

Divide both sides by 4.

h=128

Therefore, 128 hamburgers were sold on Wednesday.

Have a wonderful day! :D

-2x-9y=-25 -4x-9y=-23

goldfiish [28.3K]

So to start this off you would add 9y to both sides of the equation and then you regroup it which gives you −2x=−25+9y and then you regroup the terms and get -2x=9y-25 and then you dived both sides by -2 and get x=9y-25/-2 then you simplify and so on

but at the end you should get x=-1 and y =3
