Step-by-step explanation:
Answer:
y=-2/3x-13/3
Step-by-step explanation:
parralel line have the same gradient
y=mx+c is the general straight line equation
m represents the gradient
if the equation is y=-2/3x+3/2
m=-2/3
the coordinates (4,-7)
x=4
y=-7
substitute into equation
-7=-2/3×4+c
-7=-8/3+c
c=-7+8/3
c=-13/3
so the equation is :
y=-2/3x-13/3
Answer:
the answer is the 2nd one (3x-1) and (x+4)

This is how you are supposed to do in another question
Answer:
Number two: x > -9/2, x < 3/2
Number one: x is less than or equal to 3/4, x is greater than or equal to - 13/4
Step-by-step explanation:
Number one:
|4x+5| > 10-2
|4x+5| > 8
4x+5 > 8
-(4x+5) > 8
x > 3/4
x < -13/4
x > 3/4, x < -13/4
(all of these signs are greater than or equal to and less than or equal to)
Number two:
|2x+3| > -6
2x+3 > -6
-(2x+3) > -6
x > -9/2
x < 3/2
x> -9/2, x < 3/2
(all of these signs are correct and not greater than or equal to or less than or equal to)
