Answer:
x=-6 y=-1
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] y = -x - 7
// Plug this in for variable y in equation [1]
[1] 3x - 2•(-x -7) = -16
[1] 5x = -30
// Solve equation [1] for the variable x
[1] 5x = - 30
[1] x = - 6
// By now we know this much :
x = -6
y = -x-7
// Use the x value to solve for y
y = -(-6)-7 = -1
Solution :
{x,y} = {-6,-1}
Answer:what is 3/4÷1/2?
3/2 also know as 1 1/2
Step-by-step explanation:
P. o. symm is at (-3, -1) it is the center of the circle.
The slope is
So, the equation is
The y-intercept is when x=0, so
The ratio is 10:14 or 5:7 which is the ratio of boys to girls!
