X represents nickels
y represents dimes
x+y=29
5x+10y=210
multiply the first equation by -5 (elimination method)
-5x-5y=-145
then add the two equations together
5y=65
divide 5 from both sides
y=13
13 dimes

The answer is <span>A.) F(x) = 10(2.5)^x</span><span>.
</span>Since our base (2.5) is greater than 1, our graph would be increasing, hence it matches the given graph (it increases to the right, or towards quadrant I). Now all we need to do is solve for the y-intercept:
F(x) = 10(2.5)^x
F(0) = 10(2.5)^0 [substitute 0 in for x]
F(0) = 10(1) [any number raised to 0 would always equal 1]
y-intercept: 10
Now does it match the graph? <span><em>Yes, it does.</em>
</span>
Thus, our exponential function for this graph would be F(x) = 10(2.5)^x.
<em /><u>Tip for life</u>: When solving for the y-intercept of exponential functions, our y-intercept is always the number in front of the base (in this case, <u /><u><em>10</em></u>(2.5)^x).

Reflection and dilation is the transformation which will occur to map triangle ABC triangle to A^ * B^ n C^ prime.
<h3>What is a Triangle?</h3>
This refers to a plane figure which has features such as three angles and three sides.
Reflection and dilation involves flipping and enlargement/reduction respectively which gives rise to the sides being changed.
