Answer:

-18

Step-by-step explanation:

$3-3(6-(3-7))+3(7-4)\\\\=3-3(6-(-4))+3(7-4)\\\\=3-3(6+4)+3(7-4)\\\\=3-3(10)+3(7-4)\\\\=3-3(10)+3(3)\\\\=3-30+3(3)\\\\=3-30+9\\\\=-27+9\\\\=-18$

A) Every T is worth 7 points, and every F is worth 3 points. So if we let T = 7 and F = 3, we can count how many T's and F's each team scored and write it as an expression.

So for the East Side Bulldogs, they have 7 touchdowns and 6 field goals, thus the expression for them is:

7T + 6F

For the West Side Bulldogs, they have 5 touchdowns and 5 field goals, thus the expression for them is:

5T + 5F

B) The difference would be written as:
7T + 6F - (5T + 5F) = 2T + F

C) To determine how many more points the winning team has than the losing team, calculate the scores of the two teams. Then subtract the smaller number from the larger number to determine the score differential.

Define the domain of the following

devlian [24]

The domain of the function or relation on the graph is { -2, -1, 0, 2 and 5}

<h3>What is the domain of a function?</h3>

The domain of the function is the set of input values of the graph

<h3>How to determine the domain of the function?</h3>

The function is represented by the set of relation or ordered pairs on the graph

The graph is given as an attachment

The ordered pairs in the relation on the graph are:

(x, y) = (-2, -3), (-1, -1), (0, 3), (2, 1) and (5, 2)

Remove the y values in the above domain

x = -2, -1, 0, 2 and 5

The x values represent the domain of the function

And the domain of the function is the set of input values of the graph

Hence, the domain of the function or relation on the graph is { -2, -1, 0, 2 and 5}

The table below compares the cost of living in New York and Los Angles, with the number representing percentages of national ave

Galina-37 [17]

Answer:

The correct option for the answer is C.) $3.29 / $2.96

Step-by-step explanation:

i) national average for a gallon of gas = $2.74

ii) for transportation New York is 1.2 times the National average

therefore one gallon of gas in New York will cost = 1.2 $\times$ $2.74 = $3.29

iii)for transportation Los Angeles is 1.08 times the National average

therefore one gallon of gas in New York will cost = 1.08 $\times$ $2.74 = $2.96

Therefore you should expect to pay for gas in New York versus Los Angeles C.) $3.29 / $2.96

a gardener uses a tray of 6 conical pots to plant seeds. each conical pot has a radius of 3 centimeters and a depth of 8 centime

lubasha [3.4K]

The volume of a cone is one-third of the product of the area of the base times the height, i.e.

(1/3)π(r^2)*h = (1/3)π(3cm)^2 *(8cm) = 75.40 cm^3

Now multiply that by the number of cones: 6 * 75.40 cm^3 = 452.40 cm^3.

Then the answer is 452 cm^3
