Elena walked 20 minutes more than Lin. Jada walked twice as long as Elena. Jada walked for 90 minutes. The equation 2(x +20) = 90 describes this situation. What statement matches the (x+20) in the equation

The statement which matches "x+20" in the equation is the the time walked by Elana.

Step-by-step explanation:

According to the question.

Elena walked 20 minutes more than Lin.

Jada walked twice as long as Elena.

Jada walked for 90 minutes.

So,

Lets Lin walked for 'x' minutes.

and

Elana walked for 'x+20' minutes.

The equation can be:

⇒

⇒

⇒

⇒

⇒

⇒ minutes

So.

Lin walked for ''x'' minutes that is 25 minutes.

Elana walked for ''(x+20)'' minutes that is 45 minutes.

And Jada walked for ''2(x+20)'' that is 90 minutes.

And we see that the statement Jada walked for 90 minutes is proved in numerical way.

The statement which matches "x+20" in the equation is the the time walked by Elana.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
