Write an equation for the line in slope-intercept form.
Answer:
y = –3x – 6
Step-by-step explanation:
We'll begin by obtaining the slope of the equation y = –3x – 2.
This can be obtained by comparing
y = –3x – 2 with y = mx + c
Thus, the slope (m) of the equation
y = –3x – 2 is –3.
Next, we shall determine the slope of the equation parallel to line with equation y = –3x – 2.
This is illustrated below:
For parallel lines, the slope are related as follow:
m1 = m2
m1 = –3
m2 = m1 = –3.
Finally, we shall determine the equation as follow:
Coordinate = (–3, –3)
x1 coordinate = –3
y1 coordinate = –3
Slope (m) = –3
y –y1 = m(x – x1)
y – (–3) = –3 (x – (–3))
y + 3 = –3 (x + 3)
y + 3 = –3x – 3
Rearrange
y = –3x – 3 – 3
y = –3x – 6
Thus, the equation parallel to the line is y = –3x – 6
endpoint-(6,-10) midpoint (-1,2)
3x3 + 9x2 - 12x
If you factor 3x from the expression, you have
So, we have
We easily have
So, one solution is x=0.
The other solutions depend on the quadratic equation:
So, the solutions are
a.-441
b.-147
c.78
d.147
The total fencing material required to surround the playground and flower bedswill be 8a + 2l + 2w.
It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The boundary of a park is shaped like a circle.
The park has a rectangular playground in the center and 2 square flower beds, one on each side of the playground.
The length of the playground is l and its width is w.
The length of each side of the flower beds is a.
The total fencing material required to surround the playground and flower bedswill be
P = 2(perimeter of square) + perimeter of rectangle
Then the perimeter of the square will be
⇒ 4a
Then the perimeter of the rectangle will be
⇒ 2(l + w)
Then we have
P = 2 × 4a + 2(l + w)
P = 8a + 2l + 2w
