Hey there!

You can tell that the two angles are congruent because of the arc. So make the two angles each other.
3x-17=25-3x. Add 3x to each side. You get 6x-17=25. Add 17 to each side to get 6x=42. Divide each side by 6. You get x=7. So the value of x would be 7.

I hope this helps!

A used car has a value of 15,250 when it’s purchased in 2012. The value of the car decreases at a rate of 7.5% per year

kotegsom [21]

p=15250

r=7.5/100=0.075

y = 15250*(1 - 0.075)^x

after 8 years it would be

x = 8

y = 15250*(1 - 0.075)^8

y = $8,173.42

after 8 years the value of the car is going to be $8,173.42

Answer:

Q(-10) = 299

Step-by-step explanation:

$Q(x) = 3x^{2} - 1$ $Q(-10) = 3(-10)^{2} - 1$

$Q(-10) = 3(100) - 1$ (-10 to the second power is 100 (negative times a negative equals a positive)

$Q(-10) = 300 - 1$ 3 times 100 equal 300

$Q(-10) = 299$
