Need help solving this problem down below.​
Veronika [31]

Answer:

1 / We have the area of a rectangle ABCD = 8 x 16 = 128 ft²

2 / Find the area of an isosceles Δ DEF:

The base of the isosceles ΔDEF => DF = DC- FC = 16 -12 = 4 ft

So the area of Δ DEF = 1/2 (DF x EH) = 1/2 (4 x 6) = 12 ft²

3 / Area of the irregular shape = area ABCB + Area DEF = 128 + 12 = 140 ft²

What is the point-slope form of the equation for the line with a slope of -2 that passes through the point (4,-6)
LUCKY_DIMON [66]

Answer:

y + 6 = -2 (x-4)

Step-by-step explanation:

Point-slope formula is represented by the equation y-y_1 = m (x-x_1). When knowing a point a line crosses through and its slope, you can write an equation in this form. Substitute the m, x_1, and y_1 for real values.

The m represents the slope of the line. Since we know the slope is -2, substitute -2 for m. The x_1 and y_1 represent the x and y values of the point the line passes through. Since the line passes through (4, -6), substitute 4 for x_1 and -6 for y_1. This gives the following answer and equation:

y-(-6) = -2 (x - (4))\\y + 6 = -2 (x-4)
