Answer:
34 nickels, 39 dimes, 78 quarters
Step-by-step explanation:
q = quarters, d = dimes, n = nickels
n = d - 5
q = 2d
.25q + .10d + .05n = 7.55
<em>Plug in the first 2 equations into the third one</em>
.5d + .10d + .05(d - 5) = 7.55
<em>Open up the Parenthesis</em>
.5d + .10d + .5d - .25 = 7.55
<em>Combine Like Terms</em>
.2d - .25 = 7.55-->
.2d = 7.8 -->
d = 39 -->
n = 39 - 5 = 34
q = 2(39) = 78
3 is the max number of games she could buy
75-28 leaves 47 left divide by 15 per game
Answer:
you find the slope by putting the equation in slope intercept form y=mx+b
so you would subtract 2x and have 2y=-2x+8
then you would divide by 2 to get y be itself so
y=-x+8
So your slope is -1/1
Step-by-step explanation:
The question is incomplete. If its asking you to find the value of f(x) relative to the value of x they give you, just replace x for the value, do the math and that'll give you the value for f(x)
