The linear function y = 1.2x represents Alberto’s speed, y, in meters per minute, when his stride rate is x steps per minute.Explain what the slope and y-intercept of the linear model represent in the context of the situation.

Answers

Answer with explanation:

The linear function is given by:

$y=1.2x$

where y represents Alberto's speed in meters per minutes.

when his stride rate is x steps per minute.

We know that for any linear function of the type:

$y=mx+c$

m represents the slope and c represents the y-intercept of the function.

Here m=1.2 and c=0

i.e. the slope represents the stride rate of Alberto i.e. the rate at which he is walking.

and the y-intercept represents the speed of Alberto when he took 0 steps i.e when x=0.

It represents that his speed is 0 meter per minutes when he did not took any step.

The slope is the rate in which he is moving and the y-intercept is where he started (at 0 seconds and 0 meters).

I'm having a hard time with fractions, what is the sum of 2/5 and 2/4

Answers

We will go nice and slow...

to add fractions, you have to have a common denominator.....

that being said....a common denominator of $(2)/(5)$ and $(2)/(4)$ is 20...

So change the fractions...

$(2)/(5) * (4)/(4) = (8)/(20)$
and
$(2)/(4) * (5)/(5) = (10)/(20)$

Now, you can add..

$(8)/(20)+ (10)/(20) = (18)/(20)$ ( $(9)/(10)$ simplified)

Thus, your answer.

well first you need to get the same bottom number so the bottom number is 20 and the top will be first fraction top is 8 other fraction is 10 so your answer is 18/20

jimmy has a 60 gallon limit if he already has 1/4 of it how much more does he need to fill up the entire 60 gallons of gas? why?

Answers

I think 60 - 25 = 35 because, 1/4 is equal to a quarter for example: 3/4 is 75. Think of money! Act like someone gives you 2/4’s of Quarters and how much do they give you? 50 cents.
