Please help! i’m struggling in math so much!

Answer 1

Answer:

Question 2 ⇒ 95 calories

Question 3 ⇒ 40,933 logins

Step-by-step explanation:

Question 2.

Given:

The given equation is

$y=30x+5$-----------------------(1)

Where x = number of laps

And y = calories burned

The student walked 3 laps.

The calories would be burn after they walked 3 laps, so we substitute $x = 3$ in equation 1.

$y=30\times 3+5$

$y=90+5$

$y=95$

Therefore 95 calories would be burn if walked 3 laps.

Question 3.

The given equation is

$y=-1067x+58005$---------------------(1)

Where x = temperature

And y = number of logins

temperature is given, so we put x = 16 in equation 1.

$y=-1067\times 16+58005$

$y=-17072+58005$

$y=40933$

Therefore the outside temperature is 16° after 40,933 logins.
