Through: (-3,-5), parallel to y = 2x + 2​
Archy [21]

Answer:

y = 2x + 1

Step-by-step explanation:

Since you have an equation and a point, all you need to do is substitute the coordinates into the equation and then solve for the y-intercept (or "b"):

y = mx + b

y = 2x + 2

(-3, -5)

-5 = 2(-3) + b

-5 = -6 + b

-5 + 6 = b

b = 1

Now you have your final equation:

y = 2x + 1

*Remember that parallel lines have the same slope, so finding a new slope is not needed!

1. Slope-intercept form is y=mx+b, where m=slope and b=y-intercept. To answer this question, plug in the values they have given you.

y=mx+b
y=1/4x-5

2. To write an equation in slope-intercept form when given two points, use m=y2-y1/x2-x1

Remember: in an ordered pair, x comes first then y.

Plug the y- and x-values in. So, y2=6, y1=2 and x2=-2, x1=9

6-(-)2/-2-9= - 4/11.

The slope of your next equation would be m= - 4/11

  A) intercepts: zero profit; maximum: maximum profit. increasing: x < 4; decreasing x > 4
  B) average slope: ≈50, about $50 increased profit for each $1 increase in price.

Who is 5 times 3 related to 5 / 1/3
olya-2409 [2.1K]

Answer:

5 times 3 and 5 divide by 1/3  yield the same result - see below.

Step-by-step explanation:

When we divide by a fraction we invert it and then multiply so:

5 / 1/3

= 5 * 3/1

= 5 * 3.

SA = 2\pi rh+2\pir^2

1. Find the radius.

R = 1/2D

6 x 1/2 = 3

R = 3

2. Plug them in.

SA 2(3.14)(3)(7) + 2(3.14)(3^2)

3. Solve

3 x 7 = 21

21 x 3.14 = 65.94

65.94 x 2 = 131. 88

3^2 = 9

9 x 3.14 = 28.26

28.26 x 2 = 56.52

4. Add them together.

131.88 + 56.52 = 188.4

Answer: 188.4 square millimeters
