Step-by-step explanation:
Answer:
64
Step-by-step explanation:
-4(m-n)^2
when m=3 and n=-1
-4(3-(-1))^2=
-4(3+1)^2=
-4(4)^2=
-4(16)=-64
correct answer is -64
Answer:
y=(1/2)x+13/2
Step-by-step explanation:
2x+y=3
y=-2x+3 so the slope is -2
if another line is perpendicular to y=-2x+3, it's slope m is -(1/-2)=1/2
The line is : y-9=(1/2)(x-5)
y=(1/2)x+13/2
EXPLANATION
When x=6 and y=13 x+y = 6 + 13 = 19
x + y = 19
2.5*60 = 150 if bust travel at 60 mile per hrs his friend live 150 miles far
2.5* 63=157.5 . if bus travel 63 miles per hours friend live 157.5 miles away
