The ratio of the sides of two similar octagons is 2:5. What is the ratio of the perimeters of these octagons?

1 answer:

4 0

So we see the ratio of the sides of two similar octagons is 2:5 so let's say the first octagon has a side of 2 and the other has a side of 5. 2*8 = 16 and 5*8 = 40. 16:40 = 4:10 = and is again 2:5. So the answer is 2:5.

Convert 14x + 6y = 36 to slope intercept form.

zubka84 [21]

Answer:

y = - $\frac{7}{3}$ x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

14x + 6y = 36 ( subtract 14x from both sides )

6y = - 14x + 36 ( divide all terms by 6 )

y = - $\frac{14}{6}$ x + 6, that is

y = - $\frac{7}{3}$ x + 6 ← in slope- intercept form

On a coordinate plane, 2 right triangles are shown. The first triangle has points A (negative 1, 3), B (negative 1, 1), C (3, 1)

drek231 [11]

Answer:

B and E

Step-by-step explanation:

<u>Given</u>

ΔABC ⇒ A(- 1, 3), B(- 1, 1), C(3, 1)
ΔA'B'C' ⇒ A'(2, - 2), B'(2, - 4), C'(6, - 4)

<u>Comparing the coordinates of the corresponding vertices, we see the difference:</u>

x → x + 3, y → y - 5

It means the ΔABC has been translated 3 units right and 5 units down

Correct answer choices are B and E
