Sergio wants to write equations in the form y = mx + b for the lines passing through
point P that are parallel and perpendicular to line h. First he finds the slopes of these 2
lines. What could he do next to find the y-intercepts?

A. Multiply the slope by the x-coordinate and add the y-coordinate to the product.

B. Multiply the slope by the y-coordinate and subtract the result from the x-coordinate

C. Solve the proportion m/b = y/z for b.

D. Substitute the slope and the coordinates of point P in y = mx + b and then solve for b for each equation.

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.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
