Answer:
f(6) = 28

FunctionsFunction NotationStep-by-step explanation:
Step 1: Define
f(x) = 5x - 2
f(6) is x = 6
Step 2: Evaluate
Substitute in x [Function]: f(6) = 5(6) - 2Multiplication: f(6) = 30 - 2Subtraction: f(6) = 28=========================================================
Explanation:
Everywhere you see an x, replace it with 6
f(x) = 5x - 2
f(6) = 5*6 - 2
f(6) = 30 - 2
f(6) = 28
Remember that 5x is the same as 5*x or "5 times x". So that's why 5x turned into 5*6 after replacing x with 6. After every x is replaced, you follow the order of operations PEMDAS to simplify.

A theater sells t tickets at a price of p dollars each. The theater conducts a survey and predicts that if the price of each ticket is changed by $2, the number of tickets sold will change by 15 tickets. If n is the number of times the theater changes the ticket price by $2, the expression (p+ 2n) (t-15n) can represent the theaters's total revenue, in dollars. In this expression, what does (t-15n) represent?
A. the number of tickets that the theater will sell If the ticket price is increased by $2
B. the number of tickets the theater will sell if the ticket prices increased by $2n
C.the number of tickets the theater will sell if the ticket price is decreased by $15
Answer:
B
Step-by-step explanation:
You have to look at the second term to be sure of the meaning of t - 15n
What the given term says is that the total number of tickets sold (p) will decrease by 15 times the number of increases that there are.
The other term says that the cost of 1 ticket will increase that each ticket will increase by 2 dollars for each change in the ticket prices providing that change is 2 dollars.
C is out of the question. The information talks about 2 dollars per increase which is the first term.
A is not quite correct. It implies there is exactly 1 ticket increase. The crorect answer is the ticket increases can be a number of times (n)
The answer is B

Step-by-step explanation:
A farmer plans to grow wheat and corn. Each acre of wheat requires 4 hours of labor and $20 of capital, and each acre of corn requires 16 hours of labor and $40 of capital. The farmer has at most 800 hours of labor and $2400 of capital available. If the profit from an acre of wheat is $80 and from an acre of corn is $100, how many acres of each crop should she plant to maximize her profit?
Answer:
To maximize profits, the farmer should plant 120 acres of wheat, and no acre of corn.
Step-by-step explanation:
Given that a farmer plans to grow wheat and corn, and each acre of wheat requires 4 hours of labor and $ 20 of capital, and each acre of corn requires 16 hours of labor and $ 40 of capital, and the farmer has at most 800 hours of labor and $ 2400 of capital available, if the profit from an acre of wheat is $ 80 and from an acre of corn is $ 100, to determine how many acres of each crop should she plant to maximize her profit the following calculation must be performed:
Knowing that each acre of wheat has a 50% lower capital cost, 75% lower hours and a 20% lower profit, in principle this would be the crop to be planted to obtain better yields.
2400/20 = 120
120 x 4 = 480
120 x 80 = 9,600
Thus, to maximize profits, the farmer should plant 120 acres of wheat, and no acre of corn.

Answer:
C (H. x=3)
Step-by-step explanation:
It wants a line where both sides are equal. Since the parabola is opening upward, it has to be an x= equation. That rules out F and J. Next you count out the points to the vertex on the x axis, which seems to be 3. This means that the line is x=3, or H(c)
Find the length and width of rectangle DMLG, and calculate its area.
PLZ CACULATE ITS AREA PLZ!!
Answer:240 square feet
Step-by-step explanation:length of rectangle DMLG
= DM = LG = (25 + 5) = 30 feet
width of rectangle DMLG
= ML = 8 feet
area of rectangle DMLG
= length × width
= 30 × 8
= 240 square feet
Answer: length of rectangle DMLG
= DM = LG = (25 + 5) = 30 feet
width of rectangle DMLG
= ML = 8 feet
area of rectangle DMLG
= length × width
= 30 × 8
= 240 square feet

There were 48 blue, 48 green, and 48 yellow crayons. Also there were 72 red crayons and 120 colored pictures. What is the largest number of identical sets can be made of these crayons and pictures?
Answer:
24
Step-by-step explanation:
For this problem, you need to find the greatest common factor because you need to divide all of the materials equally into identical sets.
If you factor out the numbers 48, 72, and 120, (same # of blue, green, and yellow crayons) you'll get the GCF of 24.
48 - 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
72 - 1, 2, 3, 4, 18, 6, 8, 9, 12, 24, 36, 72
120 - 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
The greatest common factor in all of these lists is 24.
Therefore, the largest number of identical sets is 24.

A rectangular prism has a length of 714 inches, a width of 612 inches, and a height of 10 inches.
Raj has another prism that has dimensions that are each double the dimensions of the first rectangular prism.
How many times greater is the volume of the larger prism than the volume of the smaller one?
Answer:
8 timesStep-by-step explanation:
The volume of the prism:
V = lwhIf each of the dimensions is doubled, then the volume becomes:
V₁ = 2l*2w*2h = 8lwh = 8VThe larger prism has 8 times greater volume
On Monday in Minneapolis,Minnesota it’s was 0°F outside. On Tuesday it’s was 15 degrees colder. What was the temperature and Tuesday?
Answer:
-15º F.
Step-by-step explanation:
Given that on Monday in Minneapolis, Minnesota it’s was 0 ° F outside, while on Tuesday it was 15 degrees colder, to determine what was the temperature on Tuesday the following calculation must be performed:
0 - 15 = X
-15 = X
Thus, the temperature on Thursday was -15º Fahrenheit, which is equal to -26.11º Celcius.

Determine the vertex of the function f(x)=2(x+1)(x+7). You must show all algebraic steps for full marks
Answer:
vertex (-4,-18)
Step-by-step explanation:
f(x)=2(x+1)(x+7)
f(x)=2(x^2+8x+7)
f(x)=2x^2+16x+14
f(x)=2(x^2+8x)+14
f(x)=2(x^2+8x+4^2-4^2)+14
f(x)=2(x^2+8x+4^2)+2(-4^2)+14
f(x)=2(x^2+8x+4^2)+2(-4^2)+14
f(x)=2(x^2+8x+4^2)-18
f(x)=2(x+4)^2-18
vertex form:
f(x)=a(x-h)^2+k
h=-4
k=-18

Answer:
3x -4y = 12
Step-by-step explanation:
The x- and y-intercepts are easily read from the graph as 4 and -3, respectively. Then the intercept form of the equation of the line is ...
x/(x-intercept) +y/(y-intercept) = 1
x/4 +y/(-3) = 1
Multiplying by 12 will clear the fractions and give the standard form:
3x -4y = 12
