The miles per hour is 84 kilometers per 60 minutes (7:5 ratio) so if we take seven kilometers times the ratio 5/7 we get 5 minutes
Answer:
The corresponding point is (-4.-1)
Step-by-step explanation:
we know that
The point (-4,2) is on the graph of f(x)
so
For x=-4
f(x)=2
therefore
For x=-4
-(1/2)f(x)=-(1/2)*2=-1
The corresponding point is (-4.-1)
Answer: -5x-8y=-5
Step-by-step explanation:
add right sides of equation and even them with result of adding right sides of equation
4x-4y-9x-4y=-2-3
-5x-8y=-5
-15+15 - 9y =39+15
-9y=54
y= -6
