Answer:
Step-by-step explanation:
We can do this a couple of ways. We can graph it -- see below. Or we can do the math.
Math
y = x^2 - 2x - 15
This trinomial factors into
y = (x - 5)(x + 3)
from which
x - 5= 0
x = 5
and
x + 3 = 0
x = - 3
The y intercept is the value obtained when all the xs on the right = 0
y = 0^2 - 2*0 - 15
y = - 15
<em>Answer</em>
- x intercepts: (-3,0),(5,0)
- y intercept: (0,-15)
The graph is below.
Answer:
$169.96 dollars
Step-by-step explanation:
Given the following questions:
8.25% of 22.55 and 134.45
In order to find the answer, we will have to add the initial costs of the items together, then we will calculate using the formula for percentages to find the tax rate.
<u>Calculate the percentage:
</u>
<u>Add the sales tax:</u>
Which means the two items along with an 8.25% sales tax costs "$169.96 dollars."
Hope this helps.
