My "work" is to enter the equations into a graphing calculator and let it show me the answers--just as your "work" is to copy the question to Brainly.
The solutions are
(x, y) = (-0.5, 7.5)
(x, y) = (3, 25)
_____
When you equate the expressions for y, you get the quadratic
2x² -5x -3 = 0
(2x +1)(x -3) = 0
x = -1/2 or 3
y = 5(x +2) = 15/2 or 25
Answer:
if they vary together then y would be 2
Step-by-step explanation:
since they vary together 5 multiplied by 3 is 15 so you would divide 6 by 3 to get 2 the z is irrelevant because it has no relation to x or y
Answer:
(Slope intercept form)
(Slope point form)
Step-by-step explanation:
The slope of the line can be calculated as following:

The the equation of the line in slope point form is:

Where (
,
) is a point of the line.
Then you must susbtitute the point given and the slope and you obtain:

The intercept form is:

Where b is the y-intercept.
Solve for y from the equation of the line in slope point form obtained above, then:

Answer:
9 most likely
Step-by-step explanation:
This is because 3 is one away from 4, so 8 is one away from 9.
