Answer:
a. y = -x² + 2x - 8
b. y = 
c. y = x³+ 3
Step-by-step explanation:
Track 1, Track 3, Track 2, Track 4
Since angles A and C are equivalent, then angles B and D must also be equivalent. So if
angle B = angle D then...
7x + 15 = 8x
Now we just solve for x
7x + 15 = 8x
15 = 8x - 7x
15 = x
We Can check to see if it is correct by substituting 15 in for x in the equation..
7x + 15 = 8x
7 (15)+15 = 8 (15)
105 +15 = 120
120 = 120
It checks! angles B and D = 120 degrees
Answer:
188
Step-by-step explanation:
Very easy and simple division problem. All we need to do is divide the total number (2256) by the amount that they paid (12). This will give us how many people they payed for. The equation looks like this:
2256 ÷ 12 = 188.
If you need to prove this you can do 188 x 12 to find out for yourself. (It also equals 2256 proving the point.)
188 is your answer.
<u>Hope this helps and have a nice day!</u>
