Are the following figures similar? Rectangles ABCD and EFGH are shown. AB equals 5. BC equals 25. EF equals 3. FG equals 15. Yes
Tatiana [17]

Answer:

Yes; the corresponding sides are proportional

Step-by-step explanation:

If two figures are similar, the lengths of their sides are proportional.  This means if we set up a proportion with the sides we are given and cross-multiply, we get a true statement at the end of it.

Using the similarity statement ABCD~EFGH, we will compare AB to EF and BC to FG:

5/3 = 25/15

Cross multiply:

5(15) = 3(25)

75 = 75

We got a true statement, so the sides are proportional.

What is an equation for the linear function whose graph contains the points (−1, −2) and (3, 10)
sladkih [1.3K]
The equation of a line starting from two points is:
y-y_1=\frac{y_2-y_1}{x_2-x_1} \cdot (x-x_1)

From the first point you get: x1 = -1, y1 = -2
From the second point you get: x2 = 3, y2 = 10

Replace x1, y1, x2, y2 in the equation of the line and you get:
y+2=\frac{10+2}{3+1} \cdot (x+1)
y+2=\frac{12}{4} \cdot (x+1)
y+2=3 \cdot (x+1)

From this you get the equation of your line:
y(x)=3x+1
