Answer:
area = 147 sq. cm
Step-by-step explanation:
area of rectangle: length times width; since we already have the width (10), we just have to find the length. length= 6+6; 12 equation: 10 x 12 = 120
area of top triangle: 1/2 base times height; base (6), height (5)
0.5(6) x 5; equation: 3 x 5 = 15
area of bottom triangle: 1/2 base times height; base (6), height (4)
0.5(6) x 4; equation 3 x 4 = 12
120 + 15 + 12 = 147
Answer:
27
Step-by-step explanation:
72(−3/8) = (x/72)72
-3×9=x
x=-27
General formula to determine the equation of the liney - y₁ = m(x - x₁)
(x₁,y₁) is one of the points which lies n the line
m represents the slope
Find the slopeGiven:
(x₁,y₁) = (6,-6)
(x₂,y₂) = (8,8)
We could find the slope by using this formula
m =
Plug in the numbers
m =
m =
m =
m = 7
The slope is 7
Determine the line equationPlug one of the points (you could choose any of points given from the question) and the slope to the formula of line equation
y - y₁ = m(x - x₁)
y - (-6) = 7(x - 6)
y + 6 = 7x - 42
y = 7x - 42 - 6
y = 7x - 48
<em>This is the equation of the line</em>
Answer:
y = - 2x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ← m is the slope
To calculate m use the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (0, 0) ← 2 points on the line
m = = = - 2
y = - 2x ← equation of line
