Through ( 3,2) parallel to y=5/2x-5 . What is the slope intercept form of the equation

babymother [125]

Answer:

y=(5/2)x+(-11/2)

Problem: What is the slope-intercept form for a line going through (3,2) and is parallel to y=(5/2)x-5?

Step-by-step explanation:

Parallel lines have the same slope.

The slope-intercept form of a line is y=mx+b where m is the slope and b is the y-intercept. So we see that m=5/2 since that is the slope of y=5/2 x-5.

y=(5/2)x+b

We know (x,y)=(3,2) is a point on the line so replacing x with 3 and y with 2 gives:

2=(5/2)(3)+b

2=(15/2)+b

Subtract 15/2 on both sides:

2-(15/2)=b

Simplify:

(4-15)/2=b

(-11/2)=b

So the equation is:

y=(5/2)x+(-11/2)

I need help solving this for pre calc

Katarina [22]

Starting with:

$\frac{2p}{p+1} + \frac{3}{p-1} = \frac{15-p}{p^{2}-1}$

First, the difference of 2 squares shows that $p^{2} - 1 = (p+1)(p-1)$

Sub that in and multiply both sides by $(p-1)(p+1)$ :

$\frac{2p(p+1)(p-1)}{p+1} + \frac{3(p-1)(p+1)}{p-1} = \frac{(15-p)(p-1)(p+1)}{(p-1)(p+1)}$

This easily simplifies to $2p(p-1) + 3(p+1) = 15 - p$

See if you can continue from here. If not, leave a comment and I or someone else can show you the rest.

What is the value of y if 6y -2 = 34

julia-pushkina [17]

Answer:

y = 6

Step-by-step explanation:

Given

6y - 2 = 34 ( add 2 to both sides )

6y = 36 ( divide both sides by 6 )

y = 6

Given that 2x+7=27 and 3x+1=28, does 2x+7=3x+1? explain.

Anastasy [175]

No, for thing 2x and 3x have different slopes. moreover they have different y and x intercepts. you can set them equal to find an intersection since they don't have the same slope but yea
