Answer:

4\frac{1}{2} feet further.

Step-by-step explanation:

Since these are mixed numbers that are both in fourths, we can easily subtract the two numbers. However, I find it easier if we first convert both mixed numbers into improper fractions.

5\frac{1}{4} = \frac{5\cdot4+1}{4}  = \frac{21}{4}

9\frac{3}{4} = \frac{9\cdot4+3}{4}  = \frac{39}{4}

Now we can subtract the numerators:

\frac{39}{4} - \frac{21}{4} = \frac{39-21}{4} = \frac{18}{4}

\frac{18}{4} simplifies down to \frac{9}{2}.

Converting  \frac{9}{2} to a mixed number is easy - 2 goes into 9 4 times (8) with one remainder so:

4\frac{1}{2} .

Hope this helped!

The graph below shows a line of best fit for data collected on the number of dogs visiting a dog park since it first opened.
aleksandrvk [35]

Hello!

Usually in a slope intercept equation, the y-intercept is a term, and is not a coefficient of x. The slope is usually multiplied by x. This eliminates A and C as answers.

Usually the y-intercept is a starting point. Not the slope. This means that B is also incorrect.

In D, it has the correct y-intercept. It shows that 16 dogs visited the first day, and the slope shows a constant rate of more dogs.

Therefore, our answer is D.

I hope this helps!

Why is it important to keep two sides of an equation balanced when solving?
Lady_Fox [76]

Answer:

An important property of equations is one that states that you can add the same quantity to both sides of an equation and still maintain an equivalent equation.  If you think of an equation as being like a balance scale, the quantities on each side of the equation are equal, or balanced.
