Answer:
0
Step-by-step explanation:
When there is one x-intercept, the discriminant is zero.
__
The discriminant is used to compute the difference between the roots. When it is positive, the real roots are different, so there are two x-intercepts.
When the discriminant is zero, there is no difference between the roots, so there is one x-intercept (as here).
When the discriminant is negative, there are no x-intercepts and the two roots are complex.

(10,9): 10³+9³=1000+729=1729

Answer: 12s+27j≤450
Step-by-step explanation:
From the question, we are informed that Jackie has a maximum of $450 to spend on shirts and jeans and that the shirts she wants to buy are $12 each, including tax while the jeans she wants to buy are $27 each, including tax.
The inequality that represents all possible combinations of s, the number of shirts, and j, pairs of jeans, Jackie can buy will be:
= 12s+27j≤450
6/7, 12/14, 18,21, 24/28, 30/35, 36/42 in so on
