If f(x) = 3x + 2, what is f(5)?

Answers

Answer:

17

Step-by-step explanation:

f(x) is the same as y=. "What is f(5)" is the same as saying what is y=3x + 2 when x is 5.

Either way, you are going to replace x with is numerical value, which is 5, and then solve.

y = 3(5) + 2

y = 15 +2

y = 17

f(5) = 17

Michelle‘s father bought him a 16 foot board to cut into shelves for his bedroom Michelle plans to cut the board into 11 equals Size links for his shows the saw blade that Michelle will use to cut the board will change the length of the board by -0.125 inches for each cut How old is affect the total length of the board

Answers

Answer:

Step-by-step explanation:

Given that :

Length of board = 16 feet

Converting length of Board to inches:

1 foot = 12 inches

Total initial length in inches = (16 * 12) = 192 inches

To cut in 11 equal pieces : blade will have to be used 10 times

Since the Blade changes the length of each. Piece by - 0.125 inches

The total change or reduction in inch:

-0. 125 inches * 10 pieces = - 1.250 inches

Hence the total change in length :

Initial length - total reduction ;

192 inches - 1.250 inches

192 - 1.250 = 190.750

Therefore, size of each shelf will be:

190.750 / 11

= 17.34

Answers

Answer:

Step-by-step explanation:

Given expression:

1.8s + 0.65b

where,

s = the number of pounds of strawberries

b = the number of pounds bananas

If Grant bought 2.7 pounds of strawberries and 1.4 pounds of bananas

s = 2.7 pounds

b = 1.4 pounds

how much did he spend?

1.8s + 0.65b

= 1.8(2.7) + 0.65(1.4)

2. Calculate the slope of Graph E. What situation could the graph represent

3. On the blank grid , draw a line that passes through the indicated point and has the slope -2.

Answers

Answer:

Step-by-step explanation:

1). Slope of a line shown on the graph will be,

   Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

              = [tex]\frac{-4}{1}[/tex]

              = -4

2). Slope of the given horizontal line can be determined by,

    Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

    Since, rise of the given line is zero.

    Therefore, slope of the given horizontal line will be 0.

3). Slope of the line passing through the indicated line = -2

    Therefore, a line which has a rise = -2 and run = 1 can be drawn on the given blank grid (As attached).

Answers

Answer:1,512

Step-by-step explanation:

Since they are asking for the total number of books you multiply the number of shelves by the number of books each shelf can hold. 36x42

The total number of books in the library is A = 1512 books

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the total number of books in shelve = 42 books

Total number of books = Number of shelves x Number of books per shelf

Total number of books = 36 x 42

Total number of books = 1,512

Hence , the shelves in the library can hold 1,512 books all together.

The dimensions of triangle B are twice the dimensions of triangle A. The area of triangle A is 28 cm2.


What is the area of triangle B?

A.

112 cm2

B.

18 cm2

C.

12 cm2

D.

27 cm2

Answers

Answer:

Area of triangle B is 112 cm²

Option A is correct option.

Step-by-step explanation:

The dimensions of triangle B are twice the dimensions of triangle A.

Area of triangle A = 28 cm²

We need to find area of triangle B

We know that if base = b and height = h for triangle A

The area of triangle A will be: [tex]Area_A=\frac{1}{2}\times b \times h[/tex]

The dimensions for triangle B will be:

[tex]h_B = 2 h_A\\b_B = 2 b_A[/tex]

Putting in formula we get:

[tex]Area_B=\frac{1}{2}\times b\times h \\Area_B=\frac{1}{2}\times (2b)\times 2(h)\\Area_B=4( \frac{1}{2}\times b\times h)\\Area_B=4(Area_A)[/tex]

SO, we get [tex]Area_B=4(Area_A)\\[/tex]

We have Area_A = 28 cm²

Area of triangle B Area _B is:

[tex]Area_B=4(28)\\Area_B=112\:cm^2[/tex]

So, Area of triangle B is 112 cm²

Option A is correct option.
