To set the equation,we can first find how much price would be raised within a year:

=500×(1+7%)

=500×1.07

As the years go by the increase would accumulate,and the equation would be:

$500 \times {1.07}^{t}$

Find the midpoint between (4,-1) and (3,2)

zepelin [54]

Midpoint has form of,

$M(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})$

We can insert the data,

$M(\dfrac{4+3}{2},\dfrac{-1+2}{2})$

Which simplifies to,

$\boxed{M(3.5, 0.5)}$

Hope this helps.

Hi this is for texaschic101 mainly but anyone else is fine too.

Makovka662 [10]

Because the two angles on the right add to 180 degrees, we can create this system:

$(2x + 25) + y = 180$

We can also prove that $3x = 2x + 25$ , which, when solved, shows that $x = 25$ .

When plugged in to the original equation, we find that y = 105 degrees.
