What is the ratio of the total coins in Andrew's coin jar to the total coins in Staci's coin jar?

sammy [17]

Answer:the answer is D. 25:44

Step-by-step explanation: the first step is to do the cumulative total of Andrew's number of coins(100).

Then you do the cumulative total of Staci's coins(176).

After you find the cumulative total of them both, since it is Andrew:Staci, you will ratio Andrew's total to Staci's.

Which is 100:176 .

Then from here you reduce this to the lowest term

Which graph represents the linear function below?

Luba_88 [7]

Answer:

The correct option is C.

Step-by-step explanation:

The given function is

$y-4=\frac{4}{3}(x-2)$ ..... (1)

The point slope form of a linear function is

$y-y_1=m(x-x_1)$ ..... (2)

Where, m is slope and the graph passing through the point $(x_1,y_1)$ .

From (1) and (2), we get

$m=\frac{4}{3},x_1=2,y_1=4$

It means the slope of the line is positive and the graph passing though the point (2,4).

Put x=0 in the given function, to find the y-intercept.

$y-4=\frac{4}{3}(0-2)$

$y-4=\frac{-8}{3}$

$y=\frac{-8}{3}+4$

$y=\frac{-8+12}{3}$

$y=1.333$

The y-intercept is 1.333.

Put y=0 in the given function, to find the x-intercept.

$0-4=\frac{4}{3}(x-2)$

$-12=4x-8$

$-4=4x$

$x=-1$

The x-intercept is -1.

Therefore option C is correct.
