For the first one I got X=5
and for the second one I got X=6
It is a negative graph and if you take the peak- the y intercept, it gives you the value of b. make that value negative and you should get your answer. i also put my answer in the comments if you wanted it, but you said you didn’t so..
Answer:
170
Step-by-step explanation:
10 x 15 = 150
2.5 x 4 = 10
10 x 2 = 20
150 + 20 = 170
Let p, n, d represent the number of pennies, nickels, and dimes respectively. The problem statement tells us
.. p +n +d = 150
.. 2p -n = 14
.. 3p -d = 22
Add these three equations to find the number of pennies.
.. (p +n +d) +(2p -n) +(3p -d) = 150 +14 +22
.. 6p = 186
.. p = 31
.. n = 2*31 -14 = 48
.. d = 3*31 -22 = 71
Maria has 31 pennies, 48 nickels, and 71 dimes.
