Which of the following is not a real number?

Answer:

The correct answer is C

Step-by-step explanation:

If a straight line passes through [tex](x_1,y_1)[/tex] and has a slope of [tex]m[/tex] , its equation is;

[tex]y-y_1=m(x-x_1)[/tex]

In this case, we have [tex](x_1,y_1)=(5,1)[/tex] and [tex]m=\frac{1}{2}[/tex].

To find the required equation: you have to substitute [tex]x_1=5,y_1=1[/tex] and [tex]m=\frac{1}{2}[/tex] into the equation to obtain:

[tex]y-1=\frac{1}{2}(x-5)[/tex]

The correct answer is C

Answer:

Say that the price at the whole for a bottle is some x

We know that the Snack Bar sold them at 33% profit which is in dollars $0.28

i.e 33% x=0.28

so now its a matter of finding what x is 

writing this in algebraic form

0.33x=0.28

divide both sides of the equation by 0.33

0.33x/0.33=0.28/0.33

Therefore x=0.85 roughly

so the price per bottle at the whole sell is 85 cent

the snack bar is selling it for 1.13 dollars

Step-by-step explanation:

A proper fraction must have a denominator that is greater then the numerator.

If the numerator is the same as the denominator is the same then it can be simplified to 1.

If the numerator is greater than the denominator then the fraction is improper.

This means that the answer must be D) 3/4

Answer:

the number (x) is 120.

Explanation:

100% + 60% = 160% = 1.6

(just multiply it by 1.6 because it is equal to 60%)

The equation for the problem can be expressed as x + 0.6x = 192. To solve for x, you simplify the equation and isolate x, resulting in the answer of 120.

This problem is a simple algebraic problem in which we're trying to find a number that satisfies a given condition. To solve this, we need to express the problem as an equation. Let's assume the number we're looking for is denoted as x.  So, according to the problem, we have the following equation:

x + 0.60x = 192

ANSWER

The correct answer is A

EXPLANATION

The parent function is

[tex]f(x) = {x}^{3} [/tex]

The function g(x) is obtained by shifting the graph of the parent function, 4 units left and 6 units up.

Therefore the transformation is of the form:

[tex]g(x) = f(x + 4) + 6[/tex]

Hence the transformed function has equation:

[tex]g(x) = {(x + 4)}^{3} + 6[/tex]

The correct answer is A

The resulting function g(x) after the translation will be g(x) = (x+4)³ + 6

Translation is a way of changing the position of an object on an xy plane. According to the graph shown, the parent function of the graph is f(x) = x^3.

The translates function shows an upward translation by 4 units and horizontal translation to the left by 6 units. The resulting function g(x) after the translation will be g(x) = (x+4)³ + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

y = 4x + 1 ← in slope- intercept form

with y- intercept c = 1 ⇒ (0, 1) ← coordinates of y- intercept

The coordinates of the point where y-4x=1 crosses the y axis is (0, 1)

Answer:

-7.2

Step-by-step explanation:

The value of expression A•D²/C² is 1.8 x 10⁻⁷ / D².

To find the value of A•D²/C², we can first rearrange the given equations and then manipulate them to get the desired expression.

Given equations:

A • B² = 1.8 x 10⁻⁷

C • B/D = 7.2 x 10⁻⁴

Let's manipulate the second equation to get C by itself:

C • B/D = 7.2 x 10⁻⁴

C = (7.2 x 10⁻⁴) • (D/B)

Now, substitute the expression for C from the second equation into the first equation:

A • B² = 1.8 x 10⁻⁷

A = (1.8 x 10⁻⁷) / B²

Now, we have expressions for both A and C:

A = (1.8 x 10⁻⁷) / B²

C = (7.2 x 10⁻⁴) • (D/B)

Now, let's find the value of A•D²/C²:

A•D²/C² = ((1.8 x 10⁻⁷) / B²) • (B/D)²

Since (B/D)² = B²/D²:

A•D²/C² = ((1.8 x 10⁻⁷) / B²) • (B²/D²)

Now, B² in the numerator and denominator cancel out:

A•D²/C² = 1.8 x 10⁻⁷ / D²

Thus, the value of A•D²/C² is 1.8 x 10⁻⁷ / D².

Answer:

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/ (x2-x1)

   = (-3-3)/(4-1)

  =-6/3

  = -2

Then we can use point slope form to make the equation

y-y1 = m(x-x1)

y-3 = -2(x-1)

Distribute

y-3 = -2x+2

Add 3 to each side

y-3+3 = -2x+2+3

y = -2x+5

Since this is in slope intercept form, y = mx +b, the y intercept is 5

Answer: D. 5

Step-by-step explanation: First we need to find the slope

m = (y2-y1)/ (x2-x1)

  = (-3-3)/(4-1)

 =-6/3

Then we can use point slope form to make the equation

y-y1 = m(x-x1)

y-3 = -2(x-1)

Distribute

y-3 = -2x+2

Add 3 to each side

y-3+3 = -2x+2+3

y = -2x+5

Since this is in slope intercept form, y = mx +b, the y intercept is 5

Answer:

36

Step-by-step explanation:

The 10 part of the ratio represents 120 chickens. Divide 120 by 10 to find the value of one part of the ratio.

120 ÷ 10 = 12 ← value of 1 part of the ratio, hence

3 parts = 3 × 12 = 36 ← number of horses

The number of horses on the farm is​ 36.

Given that, the ratio of chicken to pigs to horses on a farm is 10:2:3 and the number of chickens on the farm is 120.

Ratio, in math, is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another.

We can write the given ratio 10:2:3 as 10x: 2x: 3x.

So, 10x=120

⇒x=12

Then, the number of horses=3x=36

Therefore, the number of horses on the farm is​ 36.

you have a 1/12.5 chance of getting a white egg. so the theoretical possibility of getting only two white eggs is 1/156.25. so it is very unlikely to get two white eggs

Answer:

0.029

Step-by-step explanation:

Last year, the porgs laid 30 dotted eggs, 40 grey eggs, and 15 white eggs.

Total eggs = 30+40+15 = 85 eggs

White eggs = 15

So, probability of getting 1 white egg = [tex]\frac{\text{No. of white eggs}}{\text{Total no. of eggs}}[/tex]

                                                              = [tex]\frac{15}{85}[/tex]

Remaining white eggs = 14

Total eggs remaining = 84

Probability of getting 1 white egg on second draw   = [tex]\frac{14}{84}[/tex]

So, the probability that you would only collect 2 white eggs =[tex]\frac{15}{85} \times \frac{14}{84}[/tex]

                                                                                                   =0.029

Hence the probability that you would only collect 2 white eggs is 0.029.

Step-by-step explanation:

Answer:

All real numbers

Step-by-step explanation:

The domain is the set of x values that we can plug into the function and it will have a y value.

The domain is the "allowed" x values of a function.

Exponential functions of the form  [tex]y=a^x[/tex], where a is a constant have domain of "all real numbers".

The function in this problem is of this form with a "-5" at the end, which shifts the function vertically 5 units down. This doesn't affect x values (or domain)

Hence, the domain is the set of all real numbers.
