15. What is the solution to 3x - 52 28?
Pani-rosa [81]

Answer:

x> 30

Step-by-step explanation:

+ First, is the inequation 3x - 52 > 28.

+ If Yes, so we can solve:

3x - 52 > 28

3x - 52 + 52 > 28 +52

3x > 90

3x/3 > 90/3 (divide both sides by 3>0)

x > 30

What is an equation of the line that passes through the points (4,-1) and (8,5)?
fiasKO [112]

Answer:

y=3/2x-7

Step-by-step explanation:

the equation of the line for slope-intercept form is y=mx+b, where  m is the slope and b is the y intercept.

we are given two points: (4,-1) and (8,5)

the equation for slope is (y2-y1)/(x2-x1)

label the points:

x1=4

y1=-1

x2=8

y2=5

now substitute into the equation:

m=(5--1)/(8-4)

m=6/4

m=3/2

the slope of the line is 3/2

here is our equation so far:

y=3/2x+b

we need to find b

since the equation will pass through the points, we can substitute either one into the equation to find b

let's use (4,-1) as an example

substitute into the equation

-1=3/2(4)+b

-1=6+b

-7=b

the y intercept is -7

so the equation is y=3/2x-7

hope this helps!
