Answer:

Step-by-step explanation:

a93 = 93 + 2(52 − 1)

a93 = 93 + 2(52 + 1)

a93 = 52 + 2(93 + 1)

a93 = 52 + 2(93 − 1)

Originally 52 - Get rid of the first 2

a93 = 52 + 2(93 + 1)

a93 = 52 + 2(93 − 1)

2 each week. - Annoying. That doesn't help.

a93 = 52 + 2(93 + 1)

a93 = 52 + 2(93 − 1)

We're not buying any new ones in the first week, so purchases are one down.

a93 = 52 + 2(93 − 1)

I think we made it.

Virty [35]

Answer:

Step-by-step explanation:

y = - \frac{1}{4} x + 3 ( equation of line t )

y - (- 2) = - \frac{1}{4} [ x - (- 2)] ⇒ y = - \frac{1}{4} x - \frac{5}{2} ( equation of line u )

Use the substitution method to solve the system of equations. Choose the correct ordered pair.
balandron [24]
Here you have 2 linear equations and are to solve this system.  Both equations have already been solved for y, so you can set one of them = to the other one:

-2x+11 = -3x+21.

Then 3x-2x = 21 - 11, or         x = 10 (answer)

Find y by subst. x = 10 into either of the given equations.

Solution is then (10, ? )
