Answer:

__X__l__Y_

1 l 3

5 l 6

9 l 9

13 l 12

17 l 15

21 l 18

On the right side, the numbers get larger by adding three each time. On the left side, the numbers get larger by adding 4 each time. It would be the same for any other pair of numbers when you add 4 to the left, and 3 to the right. For instance, the next pair would be (25 , 21). 25 would be the X value, and 21 would be the Y value.

Given that (–2, y) and (4, 6) are points on a line whose slope is-4/3 , find y.

bulgar [2K]

Answer:

The value of y is 14

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have the points

$(-2, y)\ and\ (4, 6)$

$m=-\frac{4}{3}$

substitute in the formula the given values

$-\frac{4}{3}=\frac{6-y}{4+2}$

solve for y

$-\frac{4}{3}=\frac{6-y}{6}$

Multiply by 6 both sides

$-8=6-y$

$y=6+8=14$

For #8 and #9, fill in the missing information for the following trapezoids. SHOW YOUR WORK to solve for the missing value.

garik1379 [7]

Applying the equation for the area of the trapezoid, it is found that the height is of 10 cm.

The area of a trapezoid is half the multiplication of the sum of the bases and the height, that is:

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