Mr. maddox asked four students to create a number line to find the sum of the fractions. -7/10+4/10

Hi there!

There are 3 simple steps to adding fractions:

1. Always make sure that the bottom numbers (the denominators) are the same. → In this case both denominators are 10 so we are good to go!

2. Add the top numbers (the numerators), put that answer over the denominator.

-7 + 4 = -3 →

3. Simplify the fraction (if needed). → In this case, the fraction is already simplified!

There you go! I really hope this helped, if there's anything just let me know! :)

Answer with explanation:

We have to find the sum of

, with the help of number line.

These two are rational numbers, one is negative and other is positive.

Represent these rational numbers, on the number line.

Denominator contains 10,so there are 10 divisions between 0 and 1.

Take Additive inverse of larger rational number

Mark it on the Number line.

As, the two have same denominator, Count number of lines or points  in between these two rational numbers.

Start counting points from ,.

There are three line segments or three marks to reach at .

So,

,

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2

28
