evaluate the expression 6^2 + x-x^2 for x=3

Answers

Answer 1

Answer:

30

Step-by-step explanation:

Given the following mathematical expression;

6² + x - x²

When x = 3

Thus, we would substitute the value of "x" into the expression;

36 + 3 - (3)²

Applying BODMAS (Bracket of Division, Multiplication, Addition and Subtraction).

36 + 3 - 9

39 - 9

30.

A cash register contains only five dollar and ten dollar bills. It contains three times as many five dollar bills as ten dollar bills and the total amount of
money in the cash register is $950. How many ten dollar bills are in the cash register?

Answers

Answer:

38

Step-by-step explanation:

Let x be the number of ten dollar

Number of five dollar=3x

Total amount of money in the cash register=$950

We have to find the number of ten dollar bill in the cash register.

According to question

[tex]5\times (3x)+10x=950[/tex]

[tex]15x+10x=950[/tex]

[tex]25x=950[/tex]

[tex]x=\frac{950}{25}[/tex]

[tex]x=38[/tex]

Hence, number of  ten dollar bills  in the cash register=38

Let f(x) = tan(x) - 2/x. Let g(x) = x^2 + 8. What is f(x)*g(y)?

Answers

Answer:

[tex]f(x)\times g(y)=y^2tan(x)+8tan(x)-\frac{2y^2}{x}-\frac{16}{x}[/tex]

Step-by-step explanation:

We are given that

[tex]f(x)=tan(x)-\frac{2}{x}[/tex]

[tex]g(x)=x^2+8[/tex]

We have to find [tex]f(x)\times g(y)[/tex]

To find the value of [tex]f(x)\times g(y)[/tex] we will multiply f(x) by g(y)

[tex]g(y)=y^2+8[/tex]

Now,

[tex]f(x)\times g(y)=(tanx-\frac{2}{x})(y^2+8)[/tex]

[tex]f(x)\times g(y)=tan(x)(y^2+8)-\frac{2}{x}(y^2+8)[/tex]

[tex]f(x)\times g(y)=y^2tan(x)+8tan(x)-\frac{2y^2}{x}-\frac{16}{x}[/tex]

Hence,

[tex]f(x)\times g(y)=y^2tan(x)+8tan(x)-\frac{2y^2}{x}-\frac{16}{x}[/tex]

A window is twice as long as it is wide. The area of the window is 2x where x
is the width of the window. The window is surrounded by a frame that is 2 inches
on all sides. The area of the window and frame is 2x2 + 12x +16.
What is the area of the window frame?

Answers

Answer:

When we have a rectangle of length L and width W, the area is calculated as:

A = W*L

In this case, W = x, and the area is:

A = 2*x

Then we must have  L = 2.

We know that the area of the window and the frame (together) is:

a = 2*x^2 + 12*x + 16

The area of the frame alone, will be equal to the difference between the area of both objects (a) and the area of the window alone (A)

area of the frame = a - A

                             = (2*x^2 + 12*x + 16) - (2*x) = (2*x^2 + 10*x + 16)

This is the area of the frame

Which statements describe the graph of 2 8/9 ≥ x on a number line? Select three options.

Answers

Answer:

✔️The graph contains point zero

✔️There's a closed circle on 2⁸/9

✔️The arrow points to the left

Step-by-step explanation:

The inequality, 2⁸/9 ≥ x, implies that 2⁸/9 is either equal to x or more than x. In other words, the highest value of x is 2⁸/9. Possible value of x is equal to or less than 2⁸/9.

This, on a number line, we would graph the information as follows:

✔️The graph contains point zero

Rationale: point zero is less than 2⁸/9

✔️There's a closed circle on 2⁸/9

Rationale: this indicates 2⁸/9 is included in the possible value of x

✔️The arrow points to the left

Rationale: possible value of x ranges from 2⁸/9 and below.

There is an ordered pair that is the solution of the system of equations shown. The value of one of the variables in the solution of the system can be obtained by using which of the following substitutions?

Answers

Answer:

a = 9, c = -4?

Step-by-step explanation:

i think these are the two equations, let me know if i'm wrong

2a + 3c = 5; a + 2c = 1

rearrange second equation : a = -2c +1

plug in:

2(-2c +1) +3c = 5

-4c +1 +3c = 5

-c +1 = 5

-c = 4

c = -4

a + 2(-4) = 1

a - 8 = 1

a = 9

a=9, c=4 is the answer good luck

When x = -4, y = 2(-4)+2 = -6.

When x = -3, y = 2(-3)+2 = -4.

Fill in the other values of y the same way.

Answer:

(-4, -6)(-3, -4)(-2, -2)(-1, 0)(0, 2)(1, 4)(2, 6)

Explanation:

y = 2x + 2

x: -4

y = 2(-4) + 2

y = -6

x: -3

y = 2(-3) + 2

y = -4

x: -2

y = 2(-2) + 2

y = -2

x: -1

y = 2(-1) + 2

y = 0

x: 0

y = 2(0) + 2

y = 2

x = 1

y = 2(1) + 2

y = 4

x = 2

y = 2(2) + 2

y = 6

suppose you create a graph of the cost function, c=20n + 500 of a new bookstore, and you also graph the revenue function, r=25n, where n is the number of books sold. On your graph, would the point n=150 in the loss section, the profit section, or the break-even section.

Answers

Answer:

Loss section

Step-by-step explanation:

Given

[tex]c = 20n + 500[/tex] -- cost

[tex]r = 25n[/tex] -- revenue

Required

Determine where n = 150 is

To do this, we substitute 150 for n in the given functions

[tex]c = 20n + 500[/tex]

[tex]c = 20 * 150 + 500[/tex]

[tex]c = 3500[/tex]

[tex]r = 25n[/tex]

[tex]r = 25 * 150[/tex]

[tex]r = 3750[/tex]

The above shows that the revenue is greater than cost for n = 150.

This implies that, n = 15o is the loss section.

Answer: profit section :)

1/3 of Cheryl’s savings was the same as 3/4 of Hilda’s savings.Cheryl saved $36.

(a) Find the ratio of Cheryl’s savings to Hilda’s savings.

(b) How much did Hilda save?

Answers

Answer:

a) the ratio is 9:4

b) Hilda did save $16.

Step-by-step explanation:

Let's define the variables:

C = Cheryl's savings.

H = Hilda's savings.

We know that:

(1/3)*C = (3/4)*H

We also know that Cheryl saved $36, then we have:

C = $36

Now we can replace that in the above equation to get:

(1/3)*$36 = (3/4)*H

$12 = (3/4)*H

$12*(4/3) = H = $16

Then Hilda did save $16.

And the ratio between of Cheryl's savings to Hilda's savings is:

36 : 16

We can simplify this if we divide both by 2.

(36/2) : 16/2

18 : 8

Again, we can divide both by 2:

(18/2) : (8/2)

9 : 4

Then the ratio is 9 : 4
