when you are solving these sometimes you have to get a,x,orc or any letters by itself and this case you dont
Answer:
$22,050
Step-by-step explanation:
$20,000+5%=$21,000
$21,000+5%=$22,050
-1/5 (x - 4) = -2
(-1/5)x + (4/5) = -2
-2 can be turned into -10/5
(-1/5)x = (-10/5) - (4/5)
(-1/5)x = -14/5
multiply by -5 on both sides
x = 14
hope this helps :)
Answer:
y = (x + 6)² - 1
Step-by-step explanation:
So there are two ways of doing it, completing the square or partial factoring (which is what i prefer and will show)
so we will get x first:
x^2+12x
We are factoring x
x(x+12)
Now you do x=-12/2
x=-6
Now that you have x, you plg that back into the equation to get y
y= -6^2 +12(-6) +35
= 36-36+35
=-1
Put into vertex form
y = (x + 6)² - 1

Substitute the given value of y into the equation y=7x+15

Move the variable to the left-hand side and change its sign

Collect like terms

Divide both sides of the equation by -5

Substitute the given value of x into the equation y=2x

Solve the equation for y

The possible solution of the system is the ordered pair (x,y)
