What is the rate of change of this function?
Fittoniya [83]

Answer:

21/4

Step-by-step explanation:

Rate of change also means slope.

Pick any two points, for example (8,167) and (12, 188)

Now use the formula y2-y1/x2 - x1 to find slope

188 - 167/ 12 - 8

21/4

The rate of change is 21/4, <em>note you would NOT convert the fraction into to a decimal until your teacher specifies you to.</em>

Quadrilaterals ABCD and PQRS shown below are two similar figures.<br>Find the values of x and y.​
nadezda [96]

Answer:

x = 12, y = 16

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

\frac{AD}{PS} = \frac{DC}{SR} , substitute values

\frac{20}{2x+6} = \frac{18}{27} ( cross- multiply )

18(2x + 6) = 540 ( divide both sides by 18 )

2x + 6 = 30 ( subtract 6 from both sides )

2x = 24 ( divide both sides by 2 )

x = 12

-------------------------------------------

and

\frac{AB}{PQ} = \frac{DC}{SR} , substitute values

\frac{y}{24} = \frac{18}{27} ( cross- multiply )

27y = 432 ( divide both sides by 27 )

y = 16
