Answer:
h = 5
Step-by-step explanation:
So when you are trying to find the solution to the system of equations make sure that you have it where y= -4/5x-6 and y= -30 are written like this:
-30=-4/5x-6
And then solve for x:
Add 6 on both sides.
-24=-4/5x
Then multiply by the reciprocal of -4/5.
-5/4*-24=-5/4*-4/5x
x=30
But then you are gonna want to plug 30 in for x in y=-4/5x-6 to make sure that it is the same as y=-30.
Answer:B
Step-by-step explanation:
B because 3 is still x answers are just flipped
Answer: F
Step-by-step explanation:
This is basically like 2 rectangles. Find the area of both and add them together.
Remember that the area is 
x 
.
Area of Rectangle 1: = 7, = 14
14 x 7 = 98
Area of Rectangle 2: = 5, = 14
14 x 5 = 70
Add the areas together: 98 + 70 = 168
9n is the answer to this question
