Answer:
15h² - 4h
Step-by-step explanation:
-3(2h + -5h²) + 2h
-3(2h - 5h²) + 2h
(-3*2h -3*-5h²) + 2h
-6h + 15h² + 2h
-4h + 15h²
-6h
Answer:
x > 12
Step-by-step explanation:
9x>108
x> 108/9
x > 12
Table A represents the function, because if you look at the other tables they are all relations as in order to be function we need to have one x- value coordinating to one y-value. but the other tables have multiple x-values corresponding to y values.
Answer:
The coordinate plane is like a cross right? Just remember if you go right the x value is going into the positive direction, if you go up the y value is also going into the positive direction. And positive direction means the value will increase.
So (3,0), would be further left than (10,0). Or (0,5) would be higher than (0,2) on the graph.
Answer:
The area of rectangle ABCD is 
Step-by-step explanation:
Plot the figure to better understand the problem
we have the vertices
A(-4, -2), B(-2, -2), C(-2, 7), D(-4, 7)
see the attached figure
The area of the rectangle is equal to
where
L is the length
W is the width
In this problem we have
---> difference of the y-coordinates
---> difference of the x-coordinates
substitute
