Ryan bought 6 apples and 9 peaches for a total of $7.86. madi bought 4 apples and 5 peaches for $4.82. how much are apples and peaches? write and solve a system of equations to answer the question. pls

Let's call:
a = price of 1 apple
p = price of 1 peach

The total cost is the price of 1 apple times the number of apples plus the price of 1 peach times the number of peaches, therefore the system can be:


Solve for a in the second equation (you can choose to solve for any of the variables in any of the equations, try to understand what is the best):
a = (4.82 - 5p) / 4

Now, substitute in the first equation:
6 · (4.82 - 5p) / 4 + 9p = 7.86
7.23 - (15/2)p + 9p = 7.86
(3/2)p = 0.63
p = 0.42

Now, substitute this value in the formula found for a:
a = (4.82 - 5·0.42) / 4
   = 0.68

Therefore, one apple costs 0.68$ and one peach costs 0.42$.

It’s going to be d. 4x^2-4x-19’

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
