What is the slope of a line that is parallel to y=3/4x+2
k0ka [10]
A line that is parallel to another has exactly the same slope as the other.

so a parallel line to that line above, will have the same slope hmmm what is the slope of <span>y=3/4x+2 anyway?

well, notice, since it's already in slope-intercept form   </span>\bf y=\stackrel{slope}{\cfrac{3}{4}}x~~\stackrel{y-intercept}{+2}

Write a real-world problem that can be modeled by the equation 1.25x=0.75x+50
dimulka [17.4K]
We have such equation
1.25x=0.75x+50        /-0.75x   (subtract 0.75 both sides)
1.25x-0.75x=0.75x-0.75x+50
0.5x=50          /*2   (multiply both sides times 2)
0.5x*2=50*2
x=100 - its the answer

Which shows the given inequalities in slope-intercept form?
yanalaym [24]

Answer: Solve for X      

4x−5y<1

Step-by-step explanation:

step 1 add 5y to each side

4x−5y+5y<1+5y

4x<5y+1

Step 2: Divide both sides by 4.

4x4<5y+14

x<54y+14

Answer:

x<54y+14

Let's solve for x.

12y−x<3

Step 1: Add (-1)/2y to both sides.

−x+12y+−12y<3+−12y

−x<−12y+3

Step 2: Divide both sides by -1.

−x−1<−12y+3−1

x>12y−3

Answer:

x>12y−3

now just graph 4x-5y<1 shows the given inequalities in slope -intercep form.
