At a restaurant, diners eam 1 point for every $2 they spend, plus 25 bonus points on their first meal. Function f represents the number of polnts
earned as a function of the total amount spent x. Which function represents the total amount spent as a function of the number of points
earned?

Step-by-step explanation:

We know it can't be the first two because they don't get 2 points for every $1 spent, so it has to be f(x) = 0.5x + something. That something has to be 25 because they get 25 bonus points on their first meal, so the answer has to be f(x) = 0.5x + 25. Hope this helps!

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
