Answer:

(-78/29, -619/29)

Step-by-step explanation:

Since both equations are equal to y we can set them equal to each other

15x+19 = 1/2x - 20

Subtract 1/2x from each side

15x -1/2x +19 = -20

Subtract 19 from each side

14 1/2 x +19-19 = -20-19

Changing to an improper fraction

29/2 x = -38

Multiply each side by 2/29

x = 2/29 * -38

x = -78/29

Now find y

y = 1/2x - 20

y = 1/2 (-78/29) -20

y = -39/29 - 20

Get a common denominator

 =-39/20 - 580/29

 = -619/29

  -39/29 -580/29

B. 40 is 160% of what number?
Anton [14]

Answer:

25

Step-by-step explanation:

the question basically translates to

160% x n =40  

a little trick with percents I use is that the word "of" always means multiplication.

n=40/160%=25

Write the standard equation for each circle:<br> Center at (-1,6) with radius 1/3
Sunny_sXe [5.5K]
The answer is:
(X-(-1))^2 + (Y-(6))^2 = (1/3)^2

this can be simplified into the following
(X+1)^2 + (Y-6)^2 = 1/9
