Answer:

On the second step there is a mistake. You have to multiply 2 times 2 before you add the five

Answer:

See below;

Step-by-step explanation:

We are given the following;

5 + [ 2 * 2 + 5 ], ⇒ add 2 and 5

5 + [ 2 *  7 ], ⇒ multiply 2 by 7

5 + 14, ⇒ combine like terms

Solution; 19

Now as we can see from the first ⇒ second step the process as to simplify the expression 5 + [ 2 * 2 + 5 ] further, was by adding 2 and 5. Of course by PEDMAS, it would be that multiplication takes place before that of addition, so that it should have been that 2 was multiplied by 2 first!

Solution below;

Steps |                            |

          |  5 + [ 2 * 2 + 5 ]  |

  X     |    5 + [ 2 *  7 ]     |

          |         5 + 14         |

Answer:

D

Step-by-step explanation:

you can just find the value of y and try some number of x

i.e. if x = 0, both of them will be 0

x = 1

G(x) result is -2

F(x) result is 1

x= -1

G(x) result will be 2

F(x) result is -1

so from these we can prove that G(x) is bigger graph than F(x) but flip vertically by y axis

Answer:

Option (d).

Step-by-step explanation:

Note: The base of log is missing in h(x).

Consider the given functions are

[tex]h(x)=\log_2x[/tex]

[tex]m(x)=\log_2(x+3)[/tex]

The function m(x) can be written as

[tex]m(x)=h(x+3)[/tex]           ...(1)

The translation is defined as

[tex]m(x)=h(x+a)+b[/tex]           .... (2)

Where, a is horizontal shift and b is vertical shift.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

On comparing (1) and (2), we get

[tex]a=3,b=0[/tex]

Therefore, we have to translate each point of the graph of h(x) 3 units left to get the graph of m(x).

Hence, option (d) is correct.

Answer:

3^12

Step-by-step explanation:

When multiplying the same number with different exponents you have to add the the exponents. For example:

[tex]a^x + a^y = a ^{x+y}[/tex]

So (3^6)(3)(3^5) or (3^6)(3^1)(3^5) = 3^(6+1+5) = 3^12

Answer:

B

Step-by-step explanation:

Given

n ≥ - 5

The symbol means that n can equal - 5 and values greater than - 5

Values greater than - 5 are to the right of - 5 on the number line.

- 4.5 and - 3 are to the right of - 5, thus greater than - 5

The set of values which make the inequality true are

{ - 5, - 4. 5, - 3 } → B

Answer:

g(4) = 157

Step-by-step explanation:

g(x) = 8x^2 + 9x - 7

Let x  =4

g(4) = 8 * 4^2 +9*4 -7

       =8*16 +36 - 7

        =128+36-7

        =157

Answer:

157

Step-by-step explanation:

g(x)=

[tex]{8x}^{2} + 9x - 7[/tex]

g(4) =

[tex]8( {4})^{2} + 9(4) - 7 \\g(4) = 8 \times 16 + 36 - 7 \\ g(4) = 128 + 29 \\ g(4) = 157[/tex]

Answer: 28.27

Step-by-step explanation:

Area of circle = pi * r^2

Subtract either the x coordinates or y coordinates by each other to find the length of the radius. In this case, the x coordinates have a distance when you subtract.

2 - 2 = 0

3 - 0 = 3

The radius is 3

3^2 = 9

So, the area of the circle is 9 * pi

(9)pi = 28.27433388230814

To the nearest hundredth, the area of the circle is 28.27

Answer:

8

Step-by-step explanation:

because we know its an isosceles triangle angle A and C will both be the same and since we know A = 69 C will also be 69. we also know that angles in a triangle add to 180 so take away the two 69s from the 180 to get 42

then we work backwards if its 5x + 2 then we need to do 5x - 2 to get 40 then divide it by 5 to get your answer 8!

Answer:

Yes, time play a factor in his decision, because after 3 years, option a is better, but after 9 years, option b is better.

Step-by-step explanation:

The following information is missing:

Mr. Nicholson accepts a job that pays an annual salary of $60,000. In his employment contract, he is given the option of choosing a) an annual  raise of $3,500 or b) an annual raise of 5% of his current salary.

The function that describes each situation is:

a) f(x) = 60,000 + 3,500*(x-1)

b) f(x) = 60,000*1.05^(x-1)

where x represents years and f(x) his salary.

Mr. Nicholson’s potential income for three years and nine years for each situation are:

a) f(3) = 60,000 + 3,500*(3-1) = $67,000

f(9) = 60,000 + 3,500*(9-1) = $88,000

b) f(3) = 60,000*1.05^(3-1) = $66,150

f(9) = 60,000*1.05^(9-1) = $88,647

Answer: Q

Step-by-step explanation: the 23 thing simplified would be 4 and a bunch of decimals. Q is the answer on four, and the 23 thing is closest to four, so Q would be the correct answer.

Number lines are used to represent numbers at regular interval.

[tex]\sqrt{23}[/tex] is represented by point Q

The number is given as:

[tex]\mathbf{Number = \sqrt{23}}[/tex]

Take square root of 23

[tex]\mathbf{Number = 4.79583152331}[/tex]

The above equation means that: the square root of 23 is between 4 and 5, and it is closer to 4.5 than 5.

The point on the number line that represents the above highlight is point Q.

Hence, [tex]\sqrt{23}[/tex] is represented by point Q

Answer:

sin(theta)=3/5

Step-by-step explanation:

tan(theta)=3/4

sec^2(theta)=1+tan^2(theta)=1+(3/4)^2=1+9/16=(16+9)/16=25/16

sec(theta)=square root of(25/16)=5/4

sec(theta)=1/cos(theta)=5/4

cos(theta)=4/5

sin^2(theta)=1-cos^2(theta)=1–16/25=(25–16)/25=9/25

sin(theta)=3/5

So

sec(theta)=5/4

sin(theta)=3/5

Answer:

y + 1 = -2/1 (x - 6)

Step-by-step explanation:

The above equation is written in point slope from. To find the slope of a line perpendicular to another line all you have to do is find the opposite reciprocal to the slope of the original line. The original line's slope is 1/2, the reciprocal is 2/1 and to create the opposite reciprocal you have to change the sign of the slope, so the new slope is -2/1. To finish the rest of the equation you plug in the points given to you in the question.

Answer:

Step-by-step explanation:

First, since the line is perpendicular to the given one, the slopes are negative reciprocals. The slope of the equation we must write is -2.

Now, we can set up point slope form:

y-y1 = m(x-x1)

y + 1 = -2(x - 6)

Now, we can change that to slope intercept form:

y + 1 = -2(x - 6)

y + 1 = -2x + 12

y = -2x -11

Hope this helped :)

Answer:

3/4

Step-by-step explanation:

The given equation is in the form of y=mx+b

This is where m is the slope, and b is the y intercept.

This said, the slope of the equation is 3/4.

I will attach an image of the graph. I put the equation in a graphing calculator.

If you need to graph by hand, first plot the y intercept, (0,2) and then use the slope to find more points. Then, connenct the points with a ruler.

The image you attached is not the graph of y=3/4x+2, it is the graph of y=5.

It's slope is equal to 0.
