Paralell means has same slope
y=mx+b
m=slope
given
y=3/4x-9
sloe is 3/4
y=3/4x+b
find b
given point (-8,-18)
sub
x=-8 and y=-18
-18=3/4(-8)+b
-18=-6+b
add 6
-12=b
y=3/4x-12 is equation
What the other person said:)))))
Its either 1.14 or 0.87 Hope this helps!
Answer:
4 hours and 7 hours
Step-by-step explanation:
Marcus = x hours
Donnell = x + 3 hours
Total = 11 hours
- x + x + 3 = 11
- 2x + 3 = 11
- 2x = 8
- x = 4
So Marcus practiced 4 hours and Donnell practiced 7 hours
