Answer:
point slope form y+4 = -3(x+1)
slope intercept form y = -3x-7
Step-by-step explanation:
We have a point and a slope, we can use the point slope form for the equation
y-y1 = m(x-x1)
y--4 = -3 (x--1)
y+4 = -3(x+1)
We can also manipulate the equation into slope intercept form
Distribute
y+4 = -3x -3
Subtract 4 from each side
y+4-4 =-3x-3-4
y = -3x-7
I did it on the calculator the answer was 0.1833333333333333 i do not know if this is correct if its incorrect then srry :(
The first thing we must do in this case is to solve both inequations.
We have then:
Inequality 1:
6 -2x <12
6-12 <2x
-6 <2x
-6/2 <x
-3 <x
Inequality 2:
7 + 2x <-11
2x <-11-7
2x <-18
x <-18/2
x <-9
Answer:
(-inf, -9) U (-3, inf)
