Step-by-step explanation:
Answer:
C. Yes, 3.5.
Step-by-step explanation:
If there is a relationship of direct proportionality for every ordered pair of the table, then the constant of proportionality must the same for every ordered pair. The constant of proportionality (
) is described by the following expression:
(1)
Where:
- Input.
- Output.
If we know that
,
and
, then the constants of proportionalities of each ordered pair are, respectively:









Since
, the constant of proportionality is 3.5.
First of all, lets get y on its own side of the equation.

This is slope intercept form, y=mx+b, where m is slope.
we can see that m=2, so the slope is 2 or 
Answer:
2.8
Step-by-step explanation:
Area of wooden support is 36 square inches
<em><u>Solution:</u></em>
Given that, carpenter cut out a small trapezoid as a wooden support for the front step
<em><u>The area of trapezoid is given as:</u></em>

Where, "h" is the height
"a" and 'b" are the length of base
Here given that,
Height = h = 4 inches
a = 6 inches
b = 12 inches
Substituting the values we get,

Thus area of wooden support is 36 square inches
