Answer:

  7)  (f+g)(x) = 4^x +5x -5

  8)  (f-g)(x) = 4^x +x +5

Step-by-step explanation:

7) add the two expressions.

  (f+g)(x) = f(x) +g(x) = (4^x +3x) +(2x -5)

  (f+g)(x) = 4^x +5x -5

__

8) subtract g(x) from f(x).

  (f-g)(x) = f(x) -g(x) = (4^x +3x) -(2x -5) = 4^x +3x -2x +5

  (f-g)(x) = 4^x +x +5

Answer:

BC is 24 units

Step-by-step explanation:

Given that: AB = 7 units

                  EC = 18 units

From a sketch for the question, we have a triangle ABC. Such that:

AC = AE + EC

But,

AE = AB = 7             (radius of the circle)

So that,

AC = 7 + 18

     = 25 units

Applying Pythagoras theorem to triangle ABC, we have:

[tex]/AC/^{2}[/tex] = [tex]/AB/^{2}[/tex] + [tex]/BC/^{2}[/tex]

[tex]25^{2}[/tex] = [tex]7^{2}[/tex] + [tex]/BC/^{2}[/tex]

[tex]/BC/^{2}[/tex] = 625 - 49

          = 576

BC = [tex]\sqrt{576}[/tex]

     = 24

Thus, BC is 24 units.

Answer:

C

Step-by-step explanation:

the definition of an irrational number is an infinite decimal that has no repeating pattern. rational numbers can be converted into fractions.

A is incorrect because a whole number can be converted into a fraction.

      ex: 1 is also 3/3

B is incorrect because the definition of a rational number is that it can be converted into a fraction.

D is incorrect because a terminating decimal can be made into a fraction.

      ex: 4.5 is also 9/2

D)

A Irrational number is a decimal that terminates. I hope this helps! Please rate Brainiest!

Answer:

Step-by-step explanation:

Dont listen to these bums

The second term in the sequence is 17.

An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.

Given the nth term of a sequence to be b(n)=b(n-1)+1, where n is the number of terms of the sequence

If b(1) = 16... (1)

The second term of the sequence is generated for n= 2:

b(n)=b(n-1)+1

b(2)=b(2-1)+1

b(2) = b(1)+1... (2)

Substituting equation 1 into 2

b(2) = b(1)+1

b(2) = 16 + 1 = 17

Hence, The second term in the sequence is 17.

Answer:

There is no difference. 4x and x4 are both meaning 4 times x and x times 4

Step-by-step explanation:

If x = 2, then 4 x 2 = 8.

x4 is the same thing

2 x 4 =  8

Note:

When the numbers are there together, without an operation, it means multiplication.

The value of the expression 4x is 8.

The value of the expression [tex]x^4[/tex] is 16.

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,

4x and [tex]x^4[/tex]

For x = 2,

4x = 4 x 2 = 8

[tex]x^4[/tex] = [tex]2^4[/tex] = 2 x 2 x 2 x 2 = 16

Thus,

The values of the expression are 8 and 16.

Answer:

6

Step-by-step explanation:

6 is the answer because 6 times 8 equals 48, so if you divide 48 by 8 then the quotient would equal 6.

The number 48 should be divided by 6 to equal eight is 48 ÷ 6 = 8

To find what number 48 should be divided by to equal eight, we can set up the division equation and solve for the unknown value.

Let's represent the unknown number by 'x':

48 ÷ x = 8

Now, to find the value of 'x,' we can isolate it by performing the inverse operation of division, which is multiplication. We can multiply both sides of the equation by 'x':

x * (48 ÷ x) = x * 8

On the left side, 'x' cancels out with the 'x' in the denominator, leaving us with:

48 = 8x

Next, we can solve for 'x' by dividing both sides by 8:

48 ÷ 8 = 8x ÷ 8

6 = x

Therefore, the number 48 should be divided by 6 to equal eight:

48 ÷ 6 = 8

Answer:

The slope is 5/-2.

Step-by-step explanation:

Slope is y1-y2 over m1-m2 (rise over run). The first ordered pair is -2 (m1) and 11 (y1). We then subtract the second ordered pair (4 (m2) and -4 (y2)) from the first.

11 - (-4) = 11 + 4 = 15

-2 - 4 = -6

Remember, slope is rise over run (y over x), so the slope is 15/-6. Now, we must simplify. 15/-6 = 5/-2

Dean went wrong because he thought that slope was run over rise (x over y). If he had switched the two numbers, his answer would have been correct.
