Which equation describes the inverse of f(x) = 7x + 8?

Answer:

In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations. For example, 3x² − 2xy + c is an algebraic expression.

Answer:

12

Step-by-step explanation:

The Pythagorean Theorem says that in a right triangle,  [tex](\text{leg})^2+(\text{leg})^2=(\text{hypotenuse})^2[/tex], so in this triangle, the legs are  5  and  a; the hypotenuse is 13.

[tex]5^2+a^2=13^2\\25+a^2=169\\a^2=144\\a=\sqrt{144}\\a=12[/tex]

Answer:

1/2

Answer:

  £27.50

Step-by-step explanation:

The general approach is ...

1. The area to be painted will be the area of the four walls, less the area of the door (which is assumed to be a hole in the wall, so is not painted).

Each wall has the same dimensions, so the same area. The area of the rectangular wall is ...

  A = LW

  A = (3.5 m)(2.6 m) = 9.1 m²

The area of the door is ...

  A = (2.2 m)(0.8 m) = 1.76 m²

Then the area to be painted is the area of the 4 walls less the area of the door:

  painted area = 4(9.1 m²) -1.76 m² = 34.64 m²

__

2. Each 2 L tin of paint will cover (2 L)×(8 m²/L) = 16 m², so the number of tins needed is ...

  (34.64 m²)/(16 m²/tin) = 2.165 tins

We assume this means Aisha will need to purchase 3 tins, since she will need more paint than is provided by 2 tins.

__

3. Because of the price offer on the paint, Aisha will pay full price for the first two tins, half price for the 3rd tin. That is, she will pay 2 1/2 times the full price of a tin when she buys the 3 tins of paint she needs. Each tin costs £11, so Aisha will pay ...

  (2 1/2)(£11) = £27.50

Aisha will pay £27.50 for the paint to paint her living room.

Answer:

The other term is (x-3)

Step-by-step explanation:

The quadratic function is:

[tex]f(x)=-x^{2}+7x-12[/tex]

Factoring this function we will have:

[tex]f(x)=-(x-4)(x-3)[/tex]

Therefore, the other term is (x-3).

Answer:

- 199

Step-by-step explanation:

7.

a1 = 25

d = - 16

15th term is t15.

Formula : -

an = a + ( n - 1 )d

t15

= 25 + ( 15 - 1 ) - 16

= 25 + 14 ( - 16 )

= 25 + ( - 224 )

= 25 - 224

= - 199

Answer:

-45

Step-by-step explanation:

We know that Michelle has a bank account of one hundred eighty four dollars, she then deposits thirty eight into her account, then goes shopping. Spending forty-five dollars. We are then asked the amount of money she spent being represented.

Our keyword is "spent" and "fourty-five". These determine how much money is being taken away or added.

Since we know that spending money is decreasing the amount you have, then we would need a negative sign, and since we also know the amount she spended on is forty-five, that leads us to our answer being -45

Answer: the total area is 26 in^2, which is option B

Step-by-step explanation:

ok you have to find the area of the rectangle to the left of the line and then the area of the right triangle and add them together to get the total area

so for the area of the rectangle it would be

a = Lw

a = 4 * 5 = 20 in^2

now to find the area of the triangle we first subtract 5 from 8 to see the lenght of the segment from the vertical line to the vertex of the triangle

8 - 5 = 3

so the segment is 3 inches long

the formula for the area of a triangle is (1/2)bh

(1/2)(3)(4) = 1/2 (12) = 6

so the area of the triangle is 6 in^2

now lets add the area of the rectanglke and the area of the triangle together to find the total area

20 in^2 + 6 in^2 = 26 in^2

the total area is 26 in^2, which is option B

Answer:

B. 26 square inches

Step-by-step explanation:

For the rectangle, 4 times 5 equals 20, then 4 times 3 equals 12 divided by 2 equals 6. 20 + 6 = 26

Answer:

answer in the screen shot provided

x = 6 and x = -2

Step-by-step explanation:

Put the 12 to the other side

x^2 - 4x - 12 = 0

Now factor this out:

(x - 6)(x + 2) = 0

Therefore, the roots of this equation are

x = 6 and x = -2

20.

Answer:

It is C.

Step-by-step explanation:

the division sign indicates it is evidently going to be B or C. Then it's just simple knowledge.

The statement describing the expression as the quotient of x+5 and x² - 2 option (C) is correct.

It is defined as the combination of constants and variables with mathematical operators.

We have an expression:

[tex]= \rm \dfrac{x+5}{x^2-2}[/tex]

We can write the above expression as follows:

= (x + 5) ÷ (x² - 2)

The above expression is not in the product.

The quotient of x+5 and x² - 2

Thus, the statement describing the expression as the quotient of x+5 and x² - 2 option (C) is correct.

Answer:

half of 7.4 is 3.7 so the houses are 3.7 miles apart.

Answer:

The number is either 95 or 59

Step-by-step explanation:

The two digit number would be;

(10a + b)

The reversal will be (10b + a)

The sum of the two is 154

(10a + b ) + (10b + a) = 154

11a + 11b = 154

11(a + b) = 154

a + b = 14 ••••••••(i)

The difference between the two digits is 4

Let’s have this as;

a - b = 4 ••••(ii)

from ii;

a = 4 + b

Substitute this into equation i

4 + b + b = 14

2b = 14-4

2b = 10

b = 10/2

b = 5

Recall;

a = b + 4

a = 5 + 4

a = 9

So we have the number as 95 or 59

Answer:

The offset function

Step-by-step explanation:

In Microsoft Excel, the offset function or formula returns reference to a particular cell.

The syntax is:

= OFFSET(reference, rows, cols)

Where:

reference = the base cell

rows and cols are the direction to move

For instance:

OFFSET(A1, 3, 1) will return cell B4

Because:

3 will shift down the reference from A1 to A4

1 will shift right the reference from A4 to B4

Answer:

A

Step-by-step explanation:

Given :

And we need to find the inverse of the given function. We can do it by Firstly Interchanging x and y.

So that ,

[tex]:\implies[/tex] f(x) = y

[tex]:\implies[/tex] y = ³√[ x - 9 ]

[tex]:\implies[/tex] x = ³√[ y - 9 ]

[tex]:\implies[/tex] x³ = y - 9

[tex]:\implies[/tex] y = x³ + 9

[tex]:\implies[/tex] f-¹(x) = x³ + 9

Hence option A is correct .
