Answer:

C

Step-by-step explanation:

The rate of change of a function in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [ a, b } = [ 0, 4 ]

From the graph

f(b) = f(4) = 75 and f(a) = f(0) = 15, thus

average rate of change = $\frac{75-15}{4-0}$ = $\frac{60}{4}$ = 15

Answer:

$\frac{180}{147}$

Step-by-step explanation:

Simplify $(\frac{3}{-7} - \frac{11}{21} )$

$=> \frac{(-3 \times 3) - 11}{21}$

$=> \frac{-9 - 11}{21}$

$=> \frac{-20}{21}$

Find the additive inverse of $\frac{-20}{21}$ by using its property - <em>"Sum of a number & its additive inverse is always zero". </em>Assume that 'x' is an additive inverse of $\frac{-20}{21}$ .

$=> x + \frac{-20}{21} = 0$

$=> x = 0 - (-\frac{20}{21}) = \frac{20}{21}$

Simplify $(\frac{9}{5} \div \frac{7}{5} )$

$=> \frac{9}{5} \times \frac{1}{\frac{7}{5} }$

$=> \frac{9}{5} \times \frac{5}{7}$

$=> \frac{9}{7}$

Now, find the product of $\frac{9}{7}$ & $\frac{20}{21}$

$=> \frac{9}{7} \times \frac{20}{21}$

$=> \frac{180}{147}$

Find the difference. Enter your answer in simplest terms, using the slash (/) as the fraction bar.

Kitty [74]

So, difference as in subtract? so, if it is, it would be 15. if it means percent difference, it's about 60%.

Find the value of x in the proportion. Check your answer.<br> 35/x=7/13<br> x=?

maks197457 [2]

This is super simple. Begin with cross multiplying

35/x=7/13 becomes (35)*(13)=(7) *(x)

Then multiply my love muffin, you get...

455=7x

divide both sides by 7

65=x
-or-
x=65

hope that helped :)
