Is (−5,−8) a solution of y>3x+6

Explanation:

The point (-5,-8) means x = -5 and y = -8 pair up together.

Let's plug those values into the inequality

y > 3x+6

y > 3(-5)+6 replace x with -5

-8 > 3(-5)+6 ... replace y with -8

-8 > -15+6

-8 > -9

The last inequality is true. The value -8 is larger than -9 since -8 is to the right of -9 on a number line. Stuff on the right is larger than stuff on the left.

Since the last inequality is true, this means the first inequality is true when (x,y) = (-5,-8). Therefore (-5,-8) is a solution.

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
