What is an Algebraic Expressions?When we apply the mathematical operations on constants and variables then we get the mathematical statements, these are known as algebraic expressions.The mathematical operators include, division, addition, multiplication and subtraction.

Let a number we want to find be n.

Hence, according to the given condition, the equation will be:

⇒ 6n - 7 = -49

⇒ 6n = -42

Dividing both sides by 6, we get:

n = -7

Therefore, the number that satisfy the algebraic expression is n = -7.

Answer:

214°

Step-by-step explanation:

The arc subtending an angle at the centre are equal, that is

arc ED = 90° and

arc DF = 360° - (90 + 146)° = 360° - 236° = 124°

Thus

arc EDF = arc ED + arc DF = 90° + 124° = 214°

solve for x: -8+22=13x-5-12x​

Answers

Answer:

x = 19

Step-by-step explanation:

-8 + 22 = 13x - 5 - 12x​

switch sides

13x - 5 - 12x = -8 + 22

group like terms

13x - 12x = -8 + 22 + 5

simplify:

x = 19

So, what is the pattern? For positive integers a and b: (x^a)^b

Answers

Answer: (x^b)^a

Step-by-step explanation:

the inverse of a monomial with an exponent raised to another power will give the same product if you flip the exponents.

Here we have a general rule for exponents.

We will find that:

[tex](x^a)^b = x^{a*b}[/tex]

To get this, we can first check it with some values for the exponents.

a = 2

b = 3

[tex](x^2)^3 = (x^2)*(x^2)*(x^2) = (x*x)*(x*x)*(x*x) = x^6 = x^{2*3}[/tex]

Similarly, we can prove it for two general values of a and b:

[tex](x^a)^b = (x^a)*(x^a)*...*(x^a)\\b\ times[/tex]

Now each one of these parentheses has a multiplying by itself a times.

So when we write all the x's, we will see that there are a total of b*a x's

Thus we will have:

[tex](x^a)^b = (x^a)*(x^a)*...*(x^a) = x^{a*b}[/tex]

6. The amount of time it took four soccer players to run from one goal line to the other is as follows:

Player #1 - 10.4 seconds

Player #2 - 10.1 seconds

Player #3 - 9.9 seconds

Player #4 - 9.4 seconds.

If the data was only accurate to the ones place, which soccer player's time would be different from the others?

A Player #1

B Player #3

C Player #2

D Player #4

Answers

Given:

The amount of time it took four soccer players to run from one goal line to the other is:

Player #1 - 10.4 seconds

Player #2 - 10.1 seconds

Player #3 - 9.9 seconds

Player #4 - 9.4 seconds

To find:

Soccer player whose time would be different from the others, if the data was only accurate to the ones place.

Solution:

We need to approximate the time to the ones place.

Player #1 - 10.4 seconds = 10 seconds

Player #2 - 10.1 seconds  = 10 seconds

Player #3 - 9.9 seconds  = 10 seconds

Player #4 - 9.4 seconds = 9 seconds

Therefore, the time of players 4 is different from others.

Hence, the correct option is D.

. Bartholomew Jackson is paid $10.56 an hour to knit dog sweaters. He gets paid 1.5 times his normal wages for overtime (over 40 hours per week). If he works 55.5 hours in one week, how much money does he earn

Answers

Answer:

$667.92

Step-by-step explanation:

Use the equation (p*1.5)*o=t

the variable p is equal to his hourly pay.

the variable o is equal to hours worked overtime.

the variable t is equal to the total amount of money they will make.

As for the 1.5, this is the way overtime is always calculated, at 1.5 times the rate of your hourly wage.

Back to the question:

the variable p is replaced by his hourly pay, $10.56.

the variable o is replaced by the amount of hours he worked overtime. Now, this part is a bit trickier because the question is designed to confuse you. If his overtime only counts if he works over 40 hours a week, then you need to subtract the 40 from his total amount of hours worked. You should get 15.5 because 55.5-40=15.5. Thus, variable o=15.5.

Lastly, you have to calculate it.

Plug in the variables to get:

($10.56*1.5)*15.5= $245.52

DON'T STOP HERE!!!

Since the question asks for how much he has earned for the week, you have to add this onto his normal salary. This part is easy, just multiply the 40 hours by his pay. So,

40*$10.56= $422.40.

Finally, add the overtime ($245.52) to his normal pay ($422.40).

$422.40+$245.52= $667.92

Which statement describes the inverse of m(x) = x2 – 17x?

Answers

Answer:

The correct option is;

[tex]The \ domain \ restriction \ x \geq \dfrac{17}{2} \ results \ in \ m^{-1}(x) = \dfrac{17}{2} \pm \sqrt{x + \dfrac{289}{4} }}[/tex]

Step-by-step explanation:

The given information is that m(x) = x² - 17·x

The above equation can be written in the form;

y = x² - 17·x

Therefore;

0 = x² - 17·x - y

From the general solution of a quadratic equation, 0 = a·x² + b·x + c we have;

[tex]x = \dfrac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex]

By comparison to the equation,0 = x² - 17·x - y, we have;

a = 1, b = -17, and c = -y

Substituting the values of a, b and c into the formula for the general solution of a quadratic equation, we have;

[tex]x = \dfrac{-(-17)\pm \sqrt{(-17)^{2}-4\times (1) \times (-y)}}{2\times (1)} = \dfrac{17\pm \sqrt{289+4\cdot y}}{2}[/tex]

Which can be simplified as follows;

[tex]x = \dfrac{17\pm \sqrt{289+4\cdot y}}{2}= \dfrac{17}{2} \pm \dfrac{1}{2} \times \sqrt{289+4\cdot y}} = \dfrac{17}{2} \pm \sqrt{\dfrac{289}{4} +\dfrac{4\cdot y}{4} }}[/tex]

And further simplified as follows;

[tex]x = \dfrac{17}{2} \pm \sqrt{\dfrac{289}{4} +y }} = \dfrac{17}{2} \pm \sqrt{y + \dfrac{289}{4} }}[/tex]

Interchanging x and y in the function of the inverse, m⁻¹(x), we have;

[tex]m^{-1}(x) = \dfrac{17}{2} \pm \sqrt{x + \dfrac{289}{4} }}[/tex]

We note that the maximum or minimum point of the function, m(x) = x² - 17·x found by differentiating the function and equating the result to zero, gives;

m'(x) = 2·x - 17 = 0

x = 17/2

Similarly, the second derivative is taken to determine if the given point is a maximum or minimum point as follows;

m''(x) = 2 > 0, therefore, the point is a minimum point on the graph

Therefore, as x increases past the minimum point of 17/2, m⁻¹(x) increases to give;

[tex]The \ domain \ restriction \ x \geq \dfrac{17}{2} \ results \ in \ m^{-1}(x) = \dfrac{17}{2} \pm \sqrt{x + \dfrac{289}{4} }}[/tex] to increase m⁻¹(x) above the minimum.

3 On a coordinate grid, the location of a lighthouse is at L, and the location of a buoy is at B. At noon, a ship is at the midpoint of the segment connecting the buoy and the lighthouse on the grid. Find the coordinates that best represent the ship's position at noon?​

Answers

Answer:

[tex] (\frac{1}{2}, 2) [/tex]

Step-by-step explanation:

Using the midpoint formula, [tex] M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}) [/tex], we can find the coordinates that represents the position of the ship at noon.

Let [tex] L(-4, 7) = (x_1, y_1) [/tex] (given on the coordinate plane)

[tex] B(5, -3) = (x_2, y_2) [/tex] (given also)

Plug in the values into the formula and solve as follows:

[tex] M(\frac{-4 + 5}{2}, \frac{7 +(-3)}{2}) [/tex]

[tex] M(\frac{1}{2}, \frac{7 - 3}{2}) [/tex]

[tex] M(\frac{1}{2}, \frac{4}{2}) [/tex]

[tex] M(\frac{1}{2}, 2) [/tex]

Position of the ship at noon is best represented at [tex] (\frac{1}{2}, 2) [/tex]

Given: x+y=1

Fill in: -2+3=1

Calculate: 1=1

Answer:

x = -2.

y = 3.

Step-by-step explanation:

x-y=-5

x+y=1

From the first equation

x = y - 5

Substitute this in the second equation:

y - 5 + y = 1

2y = 1 + 5 = 6

y = 3.

Substitute this into the second equation:

x + 3 = 1

x = -2.
