To find the slope you have to use the equation: y2-y1 / x2-x1

The graph of y = f(x) has a maximum point at (-2, 4).

solmaris [256]

Answer:

(2,4).

Step-by-step explanation:

Graph of y = f(-x).

The values of x in f(-x) assume the values of -x in f(x).

For example, f(-2) in f(x) is f(2) in f(-x), and f(2) in f(x) is f(-2) in f(-x).

b) Write down the coordinates of the maximum point of the graph of y = f(-x).

In f(x), we have that x = -2. So in f(-x), it will be x = 2. y remains unchanged. So

(2,4).

Amy is trying to read her grocery receipt, but it’s to blurry. The sales tax rate was 7.25%. She pays tax only on the items labe

masha68 [24]

Sales tax is .30 cents because 2.39+1.59=3.98
multiply by the sales tax which would be .075 after you move the decimal. you get .2985 cents so round it up to .30 cents

A jar contains two blue and five green marbles. A marble is drawn at random and then replaced. A second marble drawn at random.

DerKrebs [107]

corrected question:A jar contains two blue and five green marbles. A marble is drawn at random and then replaced. A second marble drawn at random. For each of the following, find the probability that: a) both marbles are blue b) both marbles are the same color c)the marbles are different in color

Answer:

Step-by-step explanation:

<u><em>The probability was done with replacement.</em></u>

Probaility of an event happening $=\frac{number of required outcomes}{number of possible outcomes}$

number of blue marbles= 2

number of green marbles=5

total number of marbles=7

(a) probability that both marbles are blue = pr(first is blue)*pr(second is blue)

$=\frac{2}{7}*\frac{2}{7}$

$=\frac{4}{49}$

(b)probability that both marbles are the same color =pr(first is blue)*pr(second is blue) + Pr(first is green)*Pr(second is green)

$=\frac{4}{49} + \frac{5}{7}*\frac{5}{7}$

$=\frac{4}{49} + \frac{25}{49}$

$=\frac{29}{49}$

(c)Probability that the marbles are different in colors=pr(first is blue)*pr(second is green) + Pr(first is green)*Pr(second is blue)

$=\frac{2}{7}*\frac{5}{7}+ \frac{5}{7}*\frac{2}{7}$

$=\frac{10}{49}+\frac{10}{49}$

$=\frac{20}{49}$

The table below shows how much money Addison earns shoveling snow for

julia-pushkina [17]

Answer:

121

Step-by-step explanation:

Since the pattern is that for each 1 driveway, she makes $11, we multiply 11*11 and get 121. We determine that each driveway makes her $11 by dividing the amount earned by the driveways shoveled.

Wyatt is working two summber jobs, washing cars and tutoring. He must work no less than 12 hours altogether between both jobs in

stiv31 [10]

Answer:

$w+t\geq 12$

Step-by-step explanation:

Please consider the complete question.

Wyatt is working two summer jobs, washing cars and tutoring. He must work no less than 12 hours altogether between both jobs in a given week. Write an inequality that would represent the possible values for the number of hours washing cars, w, and the number of hours tutoring, t, that Wyatt can work in a given week.

The number of hours altogether between both jobs would be $w+t$ .

Since Wyatt must work no less than 12 hours altogether between both jobs in a given week, so hours in both jobs should be greater than or equal to 12. We can represent this information in an inequality as:

$w+t\geq 12$

Therefore, our required inequality would be $w+t\geq 12$ .
