15x = 500-50
15x = 450
x = 450/15
x =30
Thus, x is equal to 30.
Answer:
She has enough a $26 dinner with a 20% tax
Step-by-step explanation:
Which factors can be multiplied together to make the trinomial 5x2 + 8x – 4? Check all that apply.
(x + 1)
(2x + 1)
(x + 2)
(5x + 1)
<span>(5x – 2)
Solution :
By multiplying (5x - 2) and (x + 2), the given trinomial will be obtain as follow.
</span>(5x - 2) * (x + 2) = (5x * x) + (5x * 2) - (2 * x) - (2 * 2)
= <span>5x^2 + 10x - 2x - 4
= </span>5x^2 + 8x - 4
The graph of a quadratic function does not cross the x-axis if the discriminant has negative value.
Answers:
C ) -25
D ) -7
To begin with, we have to multiply 16 by 5, to determine how many ounces are in the bags. we get 80, no? we then divide 1680 by 80 to receive 21. your answer is 21.
