Answer:

40

Step-by-step explanation:

h(x)= 4(x + 6)

Let x=4

h(4)= 4(4 + 6)

     = 4(10)

    = 40

Answer:

D

Step-by-step explanation:

So we have the function:

[tex]h(x)=4(x+6)[/tex]

To find h(4), substitute 4 for x. Thus:

[tex]h(4)=4(4+6)[/tex]

Add within the parentheses:

[tex]h(4)=4(10)[/tex]

Multiply:

[tex]h(4)=40[/tex]

The answer is D.

And we're done!

Answer:

C.  81÷3

Step-by-step explanation:

We want to write a numerical expression for the phrase: "the quotient of 81 and 3"

Quotient indicates division, so we must divide 81 by 3.

81÷3

This can be further simplified, but the questions asks for a numerical expression. This is defined as an expression with numbers and at least one operation. So, B is correct, because 81 divided by 3 is 27, but it is not a numerical expression.

Therefore, the best answer choice is C.  81÷3

Answer:

1. Substitute the value of f(x) into the problem. 8=3x-1.

2. Isolate the variable. Add 1 to both sides to isolate the variable term by using the opposite operation to move the constant term across the equal sign. ...

3. Continue to isolate the variable. ...

4. Simplify.

Answer:

y=4 - [tex]\frac{2x}{3}[/tex]

Step-by-step explanation:

The value of y for 2x + 3y = 12 is (12 - 2x) / 3.

Given,

2x + 3y = 12

We will solve for y.

We will keep the like terms on one side of the equation and solve for the required variable.

Example: x + 2x + y = 3 + 2y

Solve for y:

x + 2x + y = 3 + 2y

3x = 3 + 2y - y

3x - 3 = y

3(x - 1) = y

y = 3(x - 1) is our answer.

Solve 2x + 3y = 12 for y.

We have,

2x + 3y = 12

Keep y on one side of the equation.

3y = 12 - 2x

Divide both sides by 3.

y = (12 - 2x) / 3

Thus the value of y for 2x + 3y = 12 is (12 - 2x) / 3.

Answer:

Take a look at the 'proof' below

Step-by-step explanation:

The graph of the function g(x) is similar to that of the function f(t). The local minimum, local maximum, absolute minimum, maximum etc... of 'x' is always the closest x-intercept of the graph of f(t).

Let's check if this statement is right. The two local minimum(s) of the function f(t) occurs at x = 2, and x = 6. The two local maximum(s) occur at 1/4 and 4. As you can see the maximum / minimum of the function g(x) is always an x-intercept, x = 3, x = 7.

For part (b) the absolute maximum value of the function f(t), is 8. The closest x-intercept is 9, which is our solution.

Step-by-step explanation:

From x=0 to x=1, the function is above the x-axis, so the area is positive.

From x=1 to x=5, the area above the x-axis is greater than the area below the x-axis, so the net area is positive.

From x=5 to x=9, the area above the x-axis is greater than the area below the x-axis, so the net area is positive.

Since the area increases in each interval, the area is a maximum at x=9.

Answer:

for each letter 1 /26 is the probability

Step-by-step explanation:

probability = no. of events / no. of outcome

probability for tile A

                  = no. of events / no. of outcome

                  = 1 / 26

probability for tile B

                  = no. of events / no. of outcome

                  = 1 / 26

probability for tile C

                  = no. of events / no. of outcome

                  = 1 / 26

The distribution to 6 tables will be:

[tex]6P + 6G[/tex]

Apply distributive property

[tex]6(P + G)[/tex]

Substitute values for P and G

[tex]6(4 + 3)[/tex]

Hence, the first option answers the question

An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression when simplified is equal to 2.3684.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

As per the PEMDAS, we will first solve the parenthesis. Since the round parenthesis is solved first, therefore, we can write,

90 ÷ [10 + ( 32 − 4 )]

= 90 ÷ [10 + (28)]

= 90 ÷ [10 + 28]

Solving the next parenthesis, therefore, the square brackets,

= 90 ÷ [10 + 28]

=  90 ÷ 38

At last, we will solve the division, therefore, we can write,

= 90 ÷ 38

= 2.3684

Hence, the value of the expression when simplified is equal to 2.3684.

Answer:

$712.80

Step-by-step explanation:

648×0.10=64.8

648+64.8=712.8

The total amount paid for the refrigerator is $712.8.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Sale price = $648

Sales tax = 0.10 times the price

The total amount paid.

= 648 + 0.10 x 648

= 648 + 64.8

= 712.8

Thus,

The total amount paid is $712.8.
