A system of linear equations is shown below.
5X = 3y  2
y = X + 4
What is the x coordinate of the solution?
a.) 2
b.) 4 *****
c.) 5
d.) 1
Jean needs to graph the function below.
y = 7x ^2 + 8x 6
How many times should the graph of this function intersect the xaxis?
a.) 3
b.) 2 ******
c.) 1
d.) 0

Like_A_Boss I said check not do my Homework! OK! so mind your own business!!!!

first no I get x = 5
5X = 3y  2
3y = 3X + 12
add
5 x + 3 y = 3 x + 3 y + 10
2 x = 10
x = 5 
Shut up!

y = 7x ^2 + 8x 6
we need to make sure solution is real and not repeated
look at b^24ac
64 + 168
positive so sqrt of + number,
you are right, two real zeros 
Thanks Damon for checking my answers!
