(-2,10) is the correct answer

Use substitution
Plug in -5x for y in the second equation
x + 3(-5x) = 28
x - 15x = 28
-14x = 28, x = -2
Now plug in -2 for x in first equation
Y = -5(-2) = 10

Solution: D. (-2, 10)

The company started with 2 employees. With the information that the amount of employees grew at a steady rate per month, we could simply solve this equation by multiplying 2 by 6 to get the number of employees the company now has. The company now has 12 employees.

Given y = 2x2 - 10x. Find all real values of x for which y = -3.
Stella [2.4K]
First, plug in -3 for the y value.
-3=2x²-10x
Then, add 3 to both sides.
0=2x²-10x+3
Use the quadratic equation to solve
(-b+-√b²-4ac)/2a
You get 4.68 or 0.32
You still have to check your answer to see if there is an excluded value.
Both values check.
