Answer:
0
Step-by-step explanation:
So we have the expression:

And we want to evaluate it for x=-4 and y=8.
So, substitute:

Multiply:

Add:

Evaluate:

So, our answer is 0.
And we're done!
Answer:
The equation of the line would be y = 1/5x + 6
Step-by-step explanation:
First, to find the slope of a perpendicular line, you need to find the opposite and reciprocal of the original slope. Since the original is -5, we first change the sign (which makes it just 5). Now we take that 5 and flip it to get 1/5.
Now that we have the slope as 1/5, we can use that and the intercept in slope-intercept form to get the equation.
y = mx + b
y = 1/5x + 6
Answer:
77cm
Step-by-step explanation:
Area of a rectangle=L×B
So
7×11=77cm
Volume=length X breadth X height
hence, volume= 9.6 X 5 X 7 cubic millimeters
which is equal to 336 cubic mm
