Answer:

(1,12) is correct if you meant [tex]3 \cdot 4^x[/tex].

Please correct if I'm wrong about your expression.  

Step-by-step explanation:

I think you mean [tex]f(x)=3 \cdot 4^x[/tex].

Let's test the point and see.

A. (0,12)?

(0,12)=(x,y)

What happens when x equals 0? Is the result 12?

[tex]3 \cdot 4^0[/tex]

[tex]3 \cdot 1[/tex]

[tex]3(1)[/tex]

[tex]3[/tex]

Yep that isn't 12 so (0,12) is not on the graph of f.

B. (0,0)?

(0,0)=(x,y)

What happens when x equals 0? Is the result 0?

[tex]3 \cdot 4^0[/tex]

We already this and got 3 so (0,0) is not on the graph of f.

C.  (1,12)?

(1,12)=(1,12)

What happens when x equals 1? Is the result 12?

[tex]3 \cdot 4^1[/tex]

[tex]3 \cdot 4[/tex]

[tex]12[/tex]

The result is 12 so (1,12) is on the graph of f.

C.  (12,1)

(12,1)=(x,y)

What happens when x equals 12? Is the result 1?

[tex]3 \cdot 4^{12}[/tex]

This will result in a really big number that isn't 1 so (12,1) is not on the graph of f.

(1,12) is correct if you meant [tex]3 \cdot 4^x[/tex].

Answer:

93

Step-by-step explanation:

A quadrilateral's 4 angles add to 360 degrees

70 + 92+<1 + 105 = 360

Combine like terms

267 + <1 = 360

Subtract 267 from each side

267-267 + <1 = 360-267

<1 = 93

Answer:

93

Step-by-step explanation:

OK it's simple...

The interior angles of ANY quadrilateral (a shape with 4 sides) add up to 360.

So all you have to do is add up the angles you already know (70+92+105=267) and subtract that from 360. (360-267).

Answer:

Yes.

Step-by-step explanation:

If we add a fixed number to each term of an arithmetic sequence, we are still going to be having an arithmetic sequence.

For example, given the following sequence:

1, 3, 5, 7, 9, 11...

The difference between consecutive terms  is 2, therefore the pattern is adding two to the previous term.

If we add a fix number, let's say '3':

1+3, 3+3, 5+3, 7+3, 9+3, 11+3...

4, 6, 8, 10, 12, 14...

We notice that the pattern is the same, and it's still an arithmetic sequence.

Answer:

Step-by-step explanation:

there are 26 black cards

26/52=

0.5

Answer:

0.5

Step-by-step explanation:

A deck of cards has 52 cards. Out of which 26 are red and 26 are black. The black cards are further divided into two suits.

So,

total sample space = n(S) = 52

Let A be the event that the drawn card is a black card

Then,

n(A) = 26

So, the probability of A will be:

[tex]P(A) = \frac{n(A)}{n(S)}\\ = \frac{26}{52}\\ =\frac{1}{2}\\ =0.5[/tex]

Hence the theoretical property of drawing a black card is 0.5 ..

Answer:

R(- 12, 22 )

Step-by-step explanation:

Using the midpoint formula

[tex]\frac{1}{2}[/tex](8 + [tex]x_{R}[/tex] ) = [tex]x_{M}[/tex] = - 2

Multiply both sides by 2

8 + [tex]x_{R}[/tex] = - 4 ( subtract 8 from both sides )

[tex]x_{R}[/tex] = - 12

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

[tex]\frac{1}{2}[/tex](- 10 + [tex]y_{R}[/tex] ) = [tex]y_{M}[/tex] = 6

Multiply both sides by 2

- 10 + [tex]y_{R}[/tex] = 12 ( add 10 to both sides )

Answer:

The Solution set is (x,y){(2,5)}

Step-by-step explanation:

The given equation is:

  6x+4y=32

 -6x+4y=8

We will use the elimination method:

By this method we will eliminate the variable x.

6x+4y=32

-6x+4y=8

________

      8y=40

Divide both the sides by 8

8y/8=40/8

y=5

Now substitute the value of y in equation 2:

-6x+4y=8

-6x+4(5)=8

-6x+20=8

Move the constant value to the R.H.S

-6x=8-20

-6x= -12

Divide both the terms by -6

-6x/-6 = -12/-6

Answer:

The radius C) of a circle centered at the origin measures the distance from the origin to any point on the circle

Final answer:

The radius of a circle centered at the origin is the distance from the origin to any point on the circle, represented by the equation x² + y² = r².

Explanation:

The radius of a circle centered at the origin measures the distance from the origin to any point on the circle. When we consider the set of all points (x, y) at a fixed distance r from the origin, the equation x² + y² = r² represents a circle of radius r.

This equation is derived using the Pythagorean theorem. The radius is not to be confused with the circumference, which is the distance around the circle, or the y-coordinate, which is simply the vertical position of a point. The radius squared (r²) refers to the square of the length of the radius.

Answer:

(a + b)(a + b - 2c)

Step-by-step explanation:

Note that

(a + b)² = a² + b² + 2ab

Given

a² + b² + 2(ab - ac - bc) ← distribute parenthesis

= a² + b² + 2ab - 2ac - 2bc

= (a + b)² - 2ac - 2bc ← factor out - 2c from each term

= (a + b)² - 2c (a + b) ← factor out (a + b) from each term

= (a + b) [ a + b - 2c ]

= (a + b)(a + b - 2c) ← in factored form

The expression a² + b² + 2(ab - ac - bc) cannot be factorized using standard factorization techniques over real numbers, as a² + b² is not factorizable over the reals and there's no common factor for all terms.

To factorize the expression a² + b²+ 2(ab - ac - bc). To factorize this, we will look for a common factor and regroup the terms. Let's see if there's a way to rearrange the terms to resemble a known pattern or factor by grouping.

First, let's rewrite the expression by grouping terms with a common factor:

a² + 2ab - 2ac

b² - 2bc

However, we notice that the expression does not fit into a perfect square or any other easily factorizable form like (a + b)² or (a - b)² due to the nature of the terms a², b², and 2(ab - ac - bc). The expression is already in its simplest factored form as it stands because a²+ b² is not factorizable over the real numbers, and there's no common factor for all terms.

Therefore, the expression a² + b² + 2(ab - ac - bc) does not factorize further using real numbers and the usual factorization techniques.

Answer:

[tex]y=\frac{1}{30}(x-7)+1.5[/tex]

2.8 million is what we get in 2047

Step-by-step explanation:

Ok I see the following given in 2007, the medium salary is 1.5 million and in 2013 the medium salary is 1.7 million.

It says let x=7 represent 2007 so that means x=13 would represent 2013.

It also says y is in millions so y=1.5 means 1.5 million and y=1.7 means 1.7 million.

So we have these points that we need to find a line for:  (7,1.5) and (13,1.7).

The slope can be found by using the slope formula given two points.  This looks like this (y2-y1)/(x2-x1).

I like to line the points up and subtract then put 2nd difference over 1st difference.

Let's do that.

(13, 1.7)

-(7, 1.5)

-----------

6       .2

The slope is .2/6 or 2/60 (after multiplying top and bottom by 10) or 1/30 (after dividing top and bottom by 2)

So point slope form for this line is [tex]y-1.5=\frac{1}{30}(x-7)[/tex].

To get the point slope form for this line I just entered my m (the slope) and point (x1,y1) I knew on the line (like (7,1.5) ). Point slope form is [tex]y-y_1=m(x-x_1)[/tex].

So adding 1.5 on both sides of  [tex]y-1.5=\frac{1}{30}(x-7)[/tex] gives me  [tex]y=\frac{1}{30}(x-7)+1.5[/tex]

So now it says what is the medium salary in 2047 I believe. So we are going to plug in 47.

This gives us

[tex]y=\frac{1}{30}(47-7)+1.5[/tex]

[tex]y=\frac{1}{30}(40)+1.5[/tex]

[tex]y=\frac{4}{3}+1.5[/tex]

[tex]y=2.833333333333333333333333[/tex]

So 2.8 million

Answer:

1. D y = 8

2. C y = −8

Step-by-step explanation:

1.

Both points have y-coordinate 8, so the line is horizontal.

A horizontal line has equation

y = k

where k is the y-coordinate of all of its points.

The y-coordinate of all points on this line is 8.

Answer: y = 8

2.

A line with 0 slope is a horizontal line. All points on a horizontal line have the same y-coordinate.

A horizontal line has equation

y = k

where k is the y-coordinate of all of its points.

The y-coordinate of the given point is -8, so all points must have -8 as the y-coordinate.

Answer: y = -8

The equation of a line through two given points can be found using the point-slope form. A slope of 0 indicates a horizontal line.

To find the equation of a line that contains the points (0, 8) and (8, 8), we can use the point-slope form of a linear equation, which is y - y1 = m(x - x1). Here, (x1, y1) represents one of the points and m represents the slope. Since the y-coordinates of both points are 8, we can see that the line is horizontal. Therefore, the equation of the line is y = 8.

For the second question, a slope of 0 indicates a horizontal line. The equation of a horizontal line is y = b, where b is the y-coordinate of any point on the line. Since our point is (0, -8), the equation of the line is y = -8.

Step-by-step explanation:

* Lets explain how to solve the problem

- There are white and black circles

- There are white and black squares

- The ratio of the number of white shapes to the number of black

  shapes is 5/1

∴ The total of the ratio of the all shapes is 5 + 1 = 6

To find the equation of the line with a y-intercept of -1 and passing through the point (1,1), you first determine the slope (which is 2), leading to the slope-intercept form: y = 2x - 1. Then convert this to the general form: -2x + y + 1 = 0.

The general form of the equation of a line is Ax + By + C = 0 where A, B, and C are constants.

To write the equation of a line with a given point (1,1) and a y-intercept of -1, we'll start with the slope-intercept form of the equation, which is y = mx + b. We know that the y-intercept b is -1.

Next, we need to find the slope m, which is the change in y over the change in x. Using the point (1,1), we calculate the slope as (1 - (-1)) / (1 - 0) which equals 2.

Therefore, the slope-intercept form of our line is y = 2x - 1.

To convert this to general form, rearrange the terms and change the equation to have a 0 on one side: -2x + y + 1 = 0.

This is the general form of the equation of the line with the given conditions.

[tex]x_{1}=\frac{-1+\sqrt{-35} }{6}\\\\x_{2}=\frac{-1-\sqrt{-35} }{6}\\[/tex]

The solutions are not real numbers.

So, we know: [tex]i=\sqrt{-1}[/tex]

Finally we have:

[tex]x_{1}=\frac{-1+i\sqrt{35} }{6}\\\\x_{2}=\frac{-1-i\sqrt{35} }{6}\\[/tex]
