Showing the table of x's and y's should be present in order to get the range of the function. The range can be acquired through the y values.
A=-2;b=9;c=9;
delta=b^2-4*a*c
root1=(-b+(delta^(0.5)))/(2*a)
<span>root2=(-b-(delta^(0.5)))/(2*a)
delta =153
root1 = -0.8423
root2 =<span> 5.3423
Correct Answer is D</span></span>
Answer:
Yaritza will have to pay $83.50 dollars to go to the movies.
It will cost $31.50 for 7 snacks for her family to share.
Step-by-step explanation:
2x + y = 8
x - y = 10
--------------add
3x = 18
x = 6
x - y = 10
6 - y = 10
-y = 10 - 6
-y = 4
y = -4
solution is : (6,-4)
