Simplify:<br> 2 11/12 + 5 1/2 + 3 3/8<br> Write you answer as a mixed number.

zysi [14]

Answer:

$2\frac{11}{12} +5 \frac{1}{2} + 3\frac{3}{8}$ (write them out and convert them all into mixed fractions)

$\frac{35}{12} + \frac{11}{2} + \frac{27}{8}$ (find the LCD aka least common denominator)

$\frac{70}{24} + \frac{132}{24} + \frac{81}{24}$ (add all numerators together)

$\frac{283}{24}$ (this is improper, so you need to convert back to mixed by dividing)

$11\frac{19}{24}$ (this is your answer)

The table below shows selected points from a function.

FrozenT [24]

Answer:

<em>True </em>

Step-by-step explanation:

<em>Rate Of Change Of Functions </em>

Given a function y=f(x), the rate of change of f can be computed as the slope of the tangent line in a specific point (by using derivatives), or an approximation by computing the slope of a secant line between two points (a,b) (c,d) that belong to the function. The slope can be calculated with the formula

$\displaystyle m=\frac{d-b}{c-a}$

If this value is calculated with any pair of points and it always results in the same, then the function is linear. If they are different, the function is non-linear.

Let's take the first two points from the table (1,1)(2,4)

$\displaystyle m=\frac{4-1}{2-1}=3$

Now, we use the second and the third point (2,4) (3,9)

$\displaystyle m=\frac{9-4}{3-2}=5$

This difference in values of the slope is enough to state the function is non-linear

Answer: True
