When f(c)= 10x^2 + 3x -4, evaluate f(-4)

Answers

Answer:

[tex]f(x) = 144[/tex]

Step-by-step explanation:

This problem deals with a function. All this question is asking is to plug in -4 every time an x appears.

So, let's do that:

[tex]f(-4) = 10(-4)^{2} + 3(-4) - 4[/tex]

[tex]f(-4) = 10(16) - 12 - 4[/tex]

[tex]f(-4) = 160 - 16[/tex]

Answers

Answer:  c = 29

Work Shown:

Use the pythagorean theorem

a^2+b^2 = c^2

21^2 + 20^2 = c^2

841 = c^2

c^2 = 841

c = sqrt(841)

c = 29

Tickets to the varsity basketball game cost $4 for students, but adults pay $6, and discount tickets are $5 for senior citizens and active military. At a recent game, 353 tickets were sold for a total of $1,660. If there were twice as many student tickets sold as adult tickets, what system of equations could be used to find how many of each type of ticket were sold?

Answers

Answer:

4s + 6a + 5c = 1,660

s = 2a

s + a + c = 353

Step-by-step explanation:

s = # of student tickets bought

a = # of adult tickets bought

Answers

Answer: 2 inches

Step-by-step explanation:

14 inches

Step-by-step explanation:

Length of the hole = 16(½) inches

Length of the dirt = 8(¾)inches

The distance between the top of the pile to the bottom of the hole = ?

Since the dirt is beside the hole and not inside the hole, we can find it's length using addition.

Distance from the top to the bottom = length of dirt + length of the hole

Length of dirt = 8×¾ = 6 inches

Length of the hole = 16 × ½ = 8 inches

Distance from the top of the dirt to the bottom of the hole = (6 + 8) inches

Distance from the top of the dirt to the bottom of the hole = 14 inches

Note: the only way we can use subtraction here is if the hole was filled with dirt, what's the distance that's left

Distance left = length of hole - length of dirt

Distance left = 8 - 6 = 2 inches .

How much work is done if a person carries 5n of candy 25m when trick or treating

Answers

The amount of work done if a person carries 5n of candy 25m when trick or treating is 125.

In order to determine the amount of  work done we are going to multiply the force by the distance.

Using this formula

 

Work done = Force  x Distance

 

Where:

Force = 5n

Distance  = 25m

Let plug in the formula

Work done = 5 x 25

Work done= 125

Inconclusion the amount of work done if a person carries 5n of candy 25m when trick or treating is 125.

https://brainly.com/question/18818154

The work done  if a person carries 5n of candy 25m when trick or treating is; 125 J.

We are given;

Force carried; F = 5n

Distance covered; d = 25 m

Now, the formula for work done is given as;

Work done = Force × Distance

Thus;

Work done = 5 × 25

Work done = 125 N.m

In conclusion, the work done  if a person carries 5n of candy 25m when trick or treating is 125 N.m or 125 J.

Answers

Answer:

-27x+63

Step-by-step explanation:

you do -9 times 3x then -9 times -7, two negatives creates a positive, and so 9 times 7 equals 63

hope this helps :^)

-9(3x-7)

Multiply each term in the parentheses by -9

-9×3x-9×(-7)

Calculate the product

-27x-9×(-7)

now we do the same thing only different way ok

-9×3x

Multiplying a negative and a positive equals a negative : (-)x(+)=(-)

-(9×3)x

Multiply the numbers

-27x

-9×3x-9×(-7)

Multiply the numbers

-27x+63

Now we do the same thing only different way ok

-9×(-7)

Multiply two negatives equals a positive: (-)×(-)=(+)

9 × 7

multiply the numbers

63

Solution: -23x+63

James has $40 to spend. He wants to buy 2 tickets to a show. He has to spend $7 to get where tickets are sold. The following inequality can be used to find out the highest price James can afford to pay for each ticket. 2x+7 less than or equal to 40.
A.) x less than or equal to 23.5
B.) x less than or equal to 16.5
C.) x greater than or equal to 23.5
D.) x greater than or equal to 16.5

Answers

Answer:

B.) X less than or equal to 16.5

Step-by-step explanation:

If you take his limit, 40 and subtract the 7 dollars you will get 33. Then, divide that by two because he will need two tickets and you will get 16.5. It can't be greater than 16.5 because he will go over his budget.

Answer:

x ≤ 16.5

Step-by-step explanation:

40 ≤ 2t + 7 Subtract 7 from both sides.

40 - 7 ≤ 2t + 7 - 7

33 ≤ 2t Divide both sides by 2.

[tex]\frac{33}{2}[/tex] ≤ [tex]\frac{2t}{2}[/tex]
