The equation of this line is y - (-3) = (1/2)( x - 6 ), <span>which is equivalent to y + 3</span> = (1/2)( x - 6 );
Given a function f(x), the value of x is the x-coordinate on the x-axis. Therefore, if we wanted to find f(3) given the graph of f(x), we look for the point on the graph where x = 3, then find its y-value. That y-value is the answer to f(3).
This also applies for any other value of x.
Answer:
17 quarters, 37 nickels
Step-by-step explanation:
We just have to set up a system of equations
quarters are x
and nickels are y
x+y=54
0.25x+0.05y=6.10
now we can get ready to substitute
x=54-y
substitute it in
0.25(54-y)+0.05y=6.10
simplify/evaluate
13.5-0.25y+0.05y=6.10
-0.2y=-7.4
y=37
plug it back in
x+37=54
x=17
Answer:
125x125
125=5x5x5
125x125=5x5x5x5x5x5=5 to the power of 6
