Answer:
4
Step-by-step explanation:
The constant is the lone number, in this case it is 4.
Hope this helps.
x -y = 1
5x + 3y = 45
Solve the first equation for x: x = y + 1
Substitute x in the second with y + 1
5x + 3y = 45
5(y + 1) + 3y = 45
5y + 5 + 3y = 45
8y + 5 = 45
8y = 40
y = 5
Substitute 5 for y in x = y + 1
x = y + 1
x = 5 + 1
x = 6
Answer: (6, 5)

the answer is lbs i think
Hey there!
First, let's multiply each side of the equation by 3 to get rid of the fraction
.
9 + 2x = ![\frac{6}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B5%7D)
Next we can multiply each side of the equation by 5 to get rid of the fraction
.
45 + 10x = 6
There's your answer!
Hope this helps!
Answer:
y=1/2x+1
Step-by-step explanation:
First use slope formula.
![\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
Plug in the information needed.
![\frac{1-3}{0-4}=\frac{-2}{-4}=\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1-3%7D%7B0-4%7D%3D%5Cfrac%7B-2%7D%7B-4%7D%3D%5Cfrac%7B1%7D%7B2%7D)
The slope is
.
Now, use point-slope formula.
y-y1=m(x-x1)
Plug in the information needed.
y-3=1/2(x-4)
y-3=1/2x-2
y=1/2x+1
The equation of the line in slope-intercept form is y=1/2x+1.
Hope this helps!
If not, I am sorry.
