Answer:

3. 200

4. 9

Step-by-step explanation:

3. 300 divided by 1.5 is 200 which means 200 was the original price

4. 65 times .4 is 26 so 65 plus 26 is 91 and 100-91 is 9 so she had 9 left over

The illustration below shows the graph of yyy as a function of xxx.

Alisiya [41]

The slope of the graph of the function is equal to 0 for x between x = -3 and x = -2.
The slope of the graph of the function is equal to 0 for x between x = 3 and x = 4.
The greatest value of y is y = 4.
The smallest value of y is y = -3.

<h3>How to complete the sentences?</h3>

By critically observing the graph shown in the image attached below, we can logically deduce that the slope of the graph of this function is equal to 0 for x, between x = -3 and x = -2.

Similarly, the slope of the graph of this function is also equal to 0 for x, between x = 3 and x = 4.

Based on the graph (see attachment), the greatest value of y is 4 while the smallest value of y is -3.

What is the inverse of the function g(x) = x^3/8 + 16 ?

lesya692 [45]

Answer:

$\hookrightarrow \: { \rm{f(x) = \frac{ {x}^{3} }{8} + 16}} \\$

• let f(x) be m:

${ \rm{m = \frac{ {x}^{3} }{8} + 16}} \\$

• make x the subject of the function:

${ \rm{8m = {x}^{3} + 128}} \\ \\ { \rm{ {x}^{3} = 8m - 128 }} \\ \\ { \rm{ {x}^{3} = 8(m - 16) }} \\ \\ { \rm{x = \sqrt[3]{8} \times \sqrt[3]{(m - 16)} }} \\ \\ { \rm{x = 2 \sqrt[3]{(m - 16)} }}$

• therefore:

${ \boxed{ \rm{ {f}^{ - 1} (x) = 2 {(m - 16)}^{ \frac{1}{3} } }} }\\$

Triangle ABC has a perimeter of 22cm

Bumek [7]

Answer:

triangle ABC is "not" a right-angled triangle

Step-by-step explanation:

AB=8cm

BC=5cm

perimeter = 22cm

CA = 22 - 8 - 5 = 9

8² + 5² = 89

9² = 81

AB² + BC² ≠ CA²
