Answer:
The equation of line is y = -4x -4.
Step-by-step explanation:
Given that:
Slope of the line = -4
Line passes through the point ( -3, 8)
The general equation of line is given by;
y - y1 =m(x-x1)
Putting the point and slope in equation
y - 8 = -4(x - (-3))
y - 8 = -4(x+3)
y - 8 = -4x - 12
y = -4x - 12 + 8
y = -4x -4
Hence,
The equation of line is y = -4x -4.
Answer:
it is D
Step-by-step explanation:
just reflect by y=-1 its easy
Step-by-step explanation:
A = (1/2)bh ---> h = 2A/b = 2(12 cm^2)/(5 cm) = 4.80 cm
---> x^2 = h^2 + (b/2)^2
= (4.8 cm)^2 + (2.5)^2
= 23.04 cm^2 + 6.25 cm^2
or x = 5.41 cm
Therefore, the perimeter P is
P = 2x + b = 2(5.41 cm) + 5 cm = 15.8 cm
Answer:
A: 48in2
Step-by-step explanation:
Area of a rectangle = Length x Width
The complete figure is rectangular in shape with:
Length = 11 in
Width = 5 in
Area = 11 x 5
Area = 55 in2
The pink part is triangular in shape with:
height = 4in
Base = 3.5 in
Area of a triangle = 0.5 x base x height
Area of the pink portion = 0.5 x 3.5 x 4
Area of the pink portion = 7 in2
Area of the blue portion = (total Area) - (Area of the pink portion)
Area of the blue portion = 55 in2 - 7 in2
Area of the blue portion = 48 in 2
Hope this help you!
