Answer:

Step-by-step explanation:

A graph that represents a proportional relationship usually has the line cutting through the line of origin (0, 0).

The graph in option A does not have the line passing through the point of origin (0, 0), therefore, it does not represent a proportional relationship.

For an equation that represents a proportional relationship, it is written in the form of y = kx

Where, k is the constant of proportionality.

Therefore, the two equations given represents a proportional relationship.

(Please Help!) Find the radius of a circle so that its area and circumference have the same value.

Lapatulllka [165]

Answer:

the radius must equal 2

Step-by-step explanation:

A = pi * r^2 C = 2 * pi *r

set them equal

pi * r^2 = 2 * pi *r

divide both sides by pi

r^2 = 2 * r

divide both sides by r

r^2 /r = 2r/r

r = 2

Answer and Step-by-step explanation:

$Greetings!$

$Let's~solve~your~question!$

$To~find~the~length~of~equal~sides~of~an~isosceles~triangle,~we~use~the~following\\formula.$

$\boxed{~P=2a+b~}$

$Now,~solving~for~``a":$

$P=\frac{P}{2} -\frac{b}{2}$

$=\frac{10}{2}-\frac{2}{2}$

$=5-1$

$=4$

$Thus,~each~equal~sides~of~an~isosceles~triangle~is~4cm.$

$Hope~my~answer~helps~and~have~a~blessed~day~ahead!$

PLEASE HELP ASAP 25 POINTS

Elena L [17]

Answer: B

Step-by-step explanation:

2x - 3y = -7 → 2(2x - 3y = -7) → 4x - 6y = -14

-4x + 6y = -10 → 1(-4x + 6y = -10) → -4x + 6y = -10

0 = -24

FALSE

Since this makes a false statement, there are no solutions
