First, let the number of skis rented by x and the number of snowboards rented by y. We can then assemble the first equation from the amount of money made from the rentals.
44x + 58y = 2232
The second equation can come from the fact that 9 more skis were rented than snowboards.
y = x - 9
Therefore our system is:
44x + 58y = 2232
y = x - 9

Answer: Choice A) y = -10x^2</h3>
Explanation:
The equation y = ax^2+bx+c has the value of 'a' determine how wide or narrow the graph is. The closer 'a' is to zero, then the wider it gets; while the further 'a' is from 0, the narrower it gets.
What we need to do is look for equations in which the 'a' value is furthest from 0. In this case, it's with y = -10x^2 since a = -10 is furthest from zero compared to a = -0.9 and a = 9. Set up a number line to help see this. You can also use absolute values to get the job as well.
Therefore, y = -10x^2 has the most narrowest graph.
x = 2
given 2 secants from an external point then
Then the product of the external part and the entire secant equals the product of the external part and the entire secant of the other secant.
3 ( 3 + 5 ) = 4 (4 + x )
3 × 8 = 4 ( 4 + x ) ⇒ 24 = 4 ( 4 + x )
divide both sides by 4
6 = 4 + x ⇒ x = 6 - 4 = 2
Answer:
4,847.2
Step-by-step explanation:
$8×30=$240
$240+3%=247.2
$4,600+247.2=4,847.2
