2x + y = -5
2x + y + 5 = - 5 + 5
2x + y + 5 = 0

^ These are the steps and the answer in implicit form.


2x + y + 5
y = - 5 - 2x
y = - 2x - 5

^ These are the steps and answer written in Slope intercept form.


2x + y = -5
2x + 0 = -5
2x = -5
*Divide Borge sides by 2
x = -5/2 or -2.5

^ These are the steps and the answer written to find the x- intercept/zero.


2x + y = -5
2 * 0 + y = -5
y = -5

^ These are the steps/answer written to find the y-intercept.

Answer:

y - 5 = -3(x + 3)

Step-by-step explanation:

A parallel line has the same slope but different y-intercept

So the slope of our line is -3

We also have our x1 and y1

So input that into the point-slope formula : y - y1 = m(x - x1)

  • y -y1 = m(x - x1)
  • y - 5 = -3(x - (-3))
  • y - 5 = -3(x + 3)

The equation of the line is \boxed{\text{y - 5 = -3(x + 3)}}

The surface area of a cone is 54 square inches. What is the surface area of a similar cone that is three times as large?
12345 [234]

<u>Given</u>:

Given that the surface area of the cone is 54 square inches.

We need to determine the surface area of the cone that is similar to the cone three times large.

<u>Surface area of the similar cone:</u>

Let us determine the surface area of the similar cone.

The surface area of the similar cone can be determined by multiplying the surface area of the cone by 3. Because it is given that the similar cone is three times large.

Thus, we have;

SA = 3 \times 54

SA=162

Thus, the surface area of the similar cone is 162 square inches.
