A number is equal to twice a smaller number plus 3. The same number is equal to twice the sum of the smaller number and 1. How many solutions are possible for this situation? Answer Options:

.Infinitely many solutions exist because the two situations describe the same line.
.Exactly one solution exists because the situation describes two lines that have different slopes and different y-intercepts.

.No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.

.Exactly one solution exists because the situation describes two lines with different slopes and the same y-intercept.

No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.

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.
