Use the substitution method
h(x) = −2x −10
h(-4)= -2(-4)-10
Multiply first then do -10
8-10
h(-4)= -2
Answer : h(-4)= -2 : first choice

Step-by-step explanation:
How many boxes must she buy to cover the floor?
A. 1 box
B. 2 boxes
C. 3 boxes
D. 4 boxes
Answer:
B. 2 boxes.
Step-by-step explanation:
Area of the floor = 7 1/2 * 8 5/6
= 15/2 * 53/6
= 265/4 feet^2.
Now we divide this are by 1 square foot giving a total of 265/4
= 66.25 tiles
so she needs 2 * 45 tiles boxes (answer).
B:The base is 5 units and the height is 7 units
C:The base is 5 units and the height is 9 units
D:The base is 9 units and the height is 3 units.
To find the area of a rectangle you need to multiply the base and the height of the rectangle. In this case, for A it's 36 square units, for B it's 35 square units, for C it's 45 square units and for D it's 27 square units.
The question is asking to find the area of a rectangle for four different measurements. In Mathematics, the area of a rectangle is calculated by multiplying the base and the height. So for A the area is 4 units * 9 units = 36 square units, for B the area is 5 units * 7 units = 35 square units, for C the area is 5 units * 9 units = 45 square units, and for D the area is 9 units * 3 units = 27 square units.

Answer:
is the equation of perpendicular line.
Step-by-step explanation:
We are given , the equation of a line is
We can deduce that the slope of the given line is
The slope of its perpendicular line would be ,
Now using the point slope form,
Use the given point substituing these.
Therefore the required equation of a line that is perpendicular to y=-0.3x. +6 and that passes through the point (3,-8) is y=\frac{x}{0.3} -18[/tex]
