HELP PLEASE ASAP!!! 50 points
neonofarm [45]

Answer:

(a+b,c)

Step-by-step explanation:

Note that the midpoint formula is:

(\frac{x_{1} +x_{2}}{2}, \frac{y_{1} +y_{2}}{2})

Point A (0,0) and Point C (2a+2b,2c)

It follows that:

(\frac{(2a+2b +0}{2}, \frac{2c+0}{2})\\(\frac{(2(a+b)}{2}, \frac{2c}{2})\\\\(a+b,c)

Rita makes and sells necklaces. The materials to make each necklace cost $2.75. Last week she made 8 necklaces and wants to make
Lisa [10]

9514 1404 393

Answer:

  The equation should be 8 (x minus 2.75) = 78, and she needs to sell each necklace for $12.50.

Step-by-step explanation:

The contribution margin of each necklace is the difference between its selling price (x) and its cost (2.75). Then the total profit from 8 necklaces would be ...

  8(x -2.75)

If Rita wants that profit to be $78, then she needs to solve the equation ...

  8(x -2.75) = 78 . . . . correct equation

The solution is ...

  x -2.75 = 9.75 . . . . divide by 8

  x = 12.50 . . . . . . . . add 2.75

She needs to sell each necklace for $12.50.

Determine if xy is tangent to circle z
Kisachek [45]
Hi there!

When a segment is tangent to a circle, it is perpendicular to the radius. If you're given measurements, like the image below, you can use the pythagorean theorem to determine if the triangle is a right triangle. If the triangle is right, then the segment is tangent to the circle.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

0.45(x  + 1.6) +  5x  = 18
0.45x + 0.72 + 5x = 18
5.45x = 18 - 0.72 =  17.28
x = 17.28 / 5.45
