Brent has a model car collection. he was given 3 cars as a gift, and he adds 4 cars per year. which of the graphs below represents brent's model car collection?

The below graph represents Brent's model car collection.

Step-by-step explanation:

Let x represents the number of years and y represents total car Brent has.

Here, Brent has a model car collection. He was given 3 cars as a gift, and he adds 4 cars per year.

Thus, the total cars Brent has,

y = 4 x + 3

Which is the equation of line that shows the given situation.

The line has x-intercept = ( -3/4, 0)

And, y-intercept = (0,3)

If x= 1 y = 7

If x=2, y=11

If x=3, y=15

If x=4, y= 19

Thus, the line has the following points,

(1,7),  (2,11),  (3,15)  and (4,19)

Hence, with the help of the above information we can draw the graph of the given situation.

c.   x=2.4cm

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.
