Answer:
he has 5 quarters, 4 dimes and 6 nickles
Step-by-step explanation:
you can find this by adding the amount of coins he counted in total (19 coins) and the total amount of coins he had (15), the subtract 15 from 19 which will give you 4, this means that in both times he counted coins, only 4 of those coins in both counts were the same, and if you see, they mention dimes twice in both counts, this means the 4 coins that are shared between both counts are dimes, then dubstract 4 from 9, that's 5 so it's the 5 quarters, and substract 4 from 10 which will give you the 6 nickles
An equation, in slope-intercept form, that shows the relationship between the number of apples purchased and the total price is
y = 1.25x + 0.25.
the slope of this equation is 1.25
The relation with the slope is that each apple has a cost of 1.25 + 0.25 $.
the y-intercept of this equation is 0.25
The interception with the y axis means that the cost of production of the apple is 0.25, since, if you buy 0 apples the price is 0.25 $.
The relationship between both quantities is linear.

Undistribute -1
(-1)(y^2-9y+20)
what multiplies to 20 and adds to -9
-5 and -4
(-1)(x-5)(x-4) or
(5-x)(x-4) or
(x-5)(4+x)
