2X^2+22x+318=1270
2x^2+22x-952=0
x^2+11x-476=0
(x+28)(x-17)=0
x=17
Solution:
we are given that
A student has some $1 and $5 bills in his wallet.
Let there x $1 bills and y number of $5 bills.
He has a total of 14 bills that are worth $34.
So we can write


Now solve these two equations together using substitution as follows

Hence there are 9 $1 bills and 5 bills are of $5.
Answer: D
Explanation: I am not completely sure but the angles would be the same because they are right next to eachother
Hope this helps ;)
Answer:
(-3,2)
Step-by-step explanation:
Eliminate the equal sides of each equation and combine
5x + 17 = -2x - 4
Solve
x = -3
Evaluate y when x = −
3
.
y = 2
(-3,2)
