explain how it is possible that all proportional relationships are linear functions but not all linear functions are proportiona

OLEGan [10]

Proportional and linear functions are almost identical in form. The only difference is the addition of the “b” constant to the linear function. Indeed, a proportional relationship is just a linear relationship where b = 0, or to put it another way, where the line passes through the origin (0,0).

The following is the formula for finding the area (A) of a trapezoid with height (h) and bases (b1) and (b2). A = 1/2h(b1 + b2)

charle [14.2K]

Answer:

Correct choice: B

Step-by-step explanation:

Equation Solving

The area of a trapezoid with height h and bases b1 and b2 is given by:

$\displaystyle A=\frac{1}{2}h(b_1+b_2)$

We must solve this formula for h.

First, multiply by 2 to eliminate denominators:

$\displaystyle 2A=h(b_1+b_2)$

Now, divide by b1+b2:

$\displaystyle \frac{2A}{b_1+b_2}=h$

Swapping sides:

$\displaystyle h=\frac{2A}{b_1+b_2}$

Correct choice: B

Solve for each of the following proportions: a. 5/x=30/42 b. x/8=-12/32

andreev551 [17]

Answer:

A. x = 7

B. x = -3

Step-by-step explanation:

A. 5/x = 30/42

5/x = 5/7

5 = 5/7 x

5= 5x/7

5 x 7 = 5x

35 = 5x

35/5 = x

7 = x

x = 7

B. x/8 = -12/32

x/8 = -3/8

x = - 3/8 x 8

x = - 24/8

x = -3

Hope this helps you have a gr8 day :3
