Answer:

The first step to solving the  equation is:

[tex]3x+24 = 42[/tex]

Hence, 3x + 24 = 42 is the correct option.

Step-by-step explanation:

Given the equation

[tex]3(x+8)= 42[/tex]

First of all, we need to apply the distributive law on the left side of the equation to expand the equation.

[tex]\quad \:a\left(b+c\right)=ab+ac[/tex]

So the equation would be expaneded using the distributive law on the left side of the equation

[tex]3(x+8) = 42[/tex]

[tex]3x+24 = 42[/tex]        ∵ a(b+c) = ab + ac

Therefore, the first step to solving the  equation is:

[tex]3x+24 = 42[/tex]

Hence, 3x + 24 = 42 is the correct option.

Answer:

[tex]f(-2)=-6[/tex]

Step-by-step explanation:

[tex]f(x)=-4x^{2} +10[/tex]

At x=-2

[tex]f(-2)=-4(-2)^{2} +10[/tex]

[tex]f(-2)=-4(4) +10[/tex]

[tex]f(-2)=-16 +10[/tex]

[tex]f(-2)=-6[/tex]

Step-by-step explanation:

[tex]an = a1 + (n - 1)d \\ d = a2 - a1 \\ a1 = 20 \\ a2 = 16 \\ d = - 4 \\ an = 20 + (n - 1) \times - 4 \\ an = 20 - 4n + 4 \\ an = 24 - 4n \\ a23 = 24 - 4 \times 23 \\ a23 = - 68[/tex]

Answer:

Here we will use the relationships:

[tex]a^n*a^m = a^{n + m}[/tex]

[tex](a^n)^m = a^{n*m}[/tex]

[tex]\frac{a^n}{a^m} = a^{n - m}[/tex]

And a number:

[tex]a^n[/tex]

is between 0 and 1 if a is positive and larger than 1, and n is negative.

if a is positive and 0 < a < 1, then we need to have n positive such that:

0 < a^n < 1

A) [tex]5^3*5^{-4} = 5^{3 + (-4)} = 5^{-1}[/tex]

This is between zero and 1,

B) [tex]\frac{3^5}{3^{-6}} = 3^{5 - (-6)} = 3^{11}[/tex]

This is greater than 1, because the exponent is positive.

C) [tex](\frac{1}{4})^3*( \frac{1}{4})^2 = (\frac{1}{4})^{2 + 3} = (\frac{1}{4})^5[/tex]

Because a is smaller than 1, and the exponent is positive, then the expression is between 0 and 1.

D) [tex]\frac{(-7)^5}{(-7)^7} = (-7)^{5 - 7} = -7^{-2}[/tex]

The exponent is negative (and pair) then the expression is between 0 and 1.

Remember that when the exponent is pair, we always have that:

(-N)^m = (N)^m

So (-7)^-2 = 7^-2

Answer:

PQR = 67.4 degrees

Step-by-step explanation:

Here, we want to find the size of PQR

to do this, we proceed as follows

As we can see PR is the opposite while PQ is the hypotenuse

The trigonometric identity connecting the two is the sine

sine is the ratio of the opposite to the hypotenuse

sin Q = 12/13

Q = sin^-1(12/13)

Q = 67.4 degrees

Answer:

x = 100

Step-by-step explanation:

Since the two sides need to equal 180 degrees, we would have this as our formula: x + 23 + 57 = 180

23 + 57 is 80, and we subtract 80 from 180 to get 100 as our answer.

The required value of the variable x is 100, which is determined by the property of the supplementary angles.

As we know that supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.

Here, the two sides must equal 180 degrees.

As per the property of supplementary angle, it can be written as:

x + 23 + 57 = 180

Apply the addition operation,

x + 80 = 180

x = 180 - 80

Apply the subtraction operation to get,

x = 100

Therefore, the required value of the variable x is 100.

Answer:  -25 - 13

This simplifies to -38

So the worker's final position is 38 feet below the ground.

A diagram is shown below.

==========================================================

Explanation:

Draw a vertical number line. Plot 0 on it to indicate the ground level, or surface level. Then plot -25 on it, which is below 0. This is 25 feet below the ground.

To move 13 further feet downward, we will subtract 13 from -25. Subtracting a positive means we move downward.

For example, start at the 30th of a building. This is marked as +30 or just 30 on the vertical number line. Subtract off 13 to go down 13 floors and we have 30-13 = 17. So after going down 13 floors, we're at the 17th floor now.

Going back to the problem at hand, we start at -25 and subtract off 13 to get the final answer -25 - 13

The answer is not -25 - -13 and it is not -25 - (-13). This is because the two negatives cancel to be a positive. So -25 - (-13) becomes -25+13. Here we're starting at -25 but then going up 13 feet. Instead we want to go down 13 feet.

------------------------------------

After we determine the expression is -25 - 13 we will effectively add the positive versions of those numbers like so

25+13 = 38

But the final answer is negative because we're starting underground and moving further underground.

We can write it like this

-25 - 13 = -(25+13) = -(38) = -38

Therefore, if the worker starts off 25 feet underground, and moves 13 feet downward, then the worker ends up 38 feet underground. Again, use the vertical number line to help see this.

Answer:

12

Step-by-step explanation:

12 doesn't fit the data because it is so much farther from the general average of the others.

12 affects the median because with it, the median is 74. but without 12, the median is 76.

12 affects the mean because with it, the mean is 68.36. but without 12, the mean is 72.69.

f(2) = 30

Step-by-step explanation:

f(x) = 2x² − 3x + 28

f(2) = 2(2)² - 3(2) + 28

f(2) = 2(4) - 6 + 28

f(2) = 8 - 6 + 28

f(2) = 30
