Hey there! :)

Answer:

y = 0, also known as the x-axis.

Step-by-step explanation:

The equation [tex]f(x) = \frac{2}{3} ^{x}[/tex] is an exponential function.

There is an asymptote at y = 0, or the x-axis because:

[tex]\frac{2}{3} ^{x}\neq 0[/tex]

An exponential function, unless containing a vertical shift, can never cross the x-axis resulting in an asymptote at y = 0.

Answer:

1, 2, 4, 8, 16...

Step-by-step explanation:

To be a geometric sequence there must be a common ratio which basically means the number you multiply a term by to get the next one, and the common ratio must be the same between all terms. The only sequence that follows this is the first one.

Answer:

Step-by-step explanation:

Each term of a geometric sequence is a multiple of the previous term.  For example, if the first term is 2 and the common ratio is 3, then the next term is 6; the next term is 18.  And so on.

1,2,4,8,16.... fits this pattern.  The first term is 1 and each succeeding term is 2 times the previous term:  1*2 = 2; 2*2 = 4; 4*2 = 8, and so on.

Step-by-step explanation:

just simplify the above equation and substitute in the second one.

Answer:

Step-by-step explanation:

2x+3y=6 -----1

3x-5y=2-----2

solving by elimination method,

multiply eq1 with3

multiply eq2 with2

you will get,

6x+9y=18----3

6x-10y=4----4

eq3-eq4=

19y=14

y=14/19------5

substitute eq 5 in eq 1

you will get,

x=50/19...

Answer:

The deck width is 3

Step-by-step explanation:

Your

x(x + 2) =15

x + 2x -15 =0

should be:

x(x + 2) =15

x^2 + 2x -15 =0.

Factoring this, we get

x^2 + 2x -15 =0 = (x + 5)(x - 3) = 0,

which yields:  x = 3 and x = -5.  As the problem states, we discard the negative root and focus on the positive one (x = 3).

The deck width is 3 and the length is (3 + 2), or 5.

Answer:

y - 7 = (1/10)(x - 5)

Step-by-step explanation:

Next time please share the possible answers.  Thank you.

Any line perpendicular to y = -10x + 1 has the slope +1/10, which is the negative reciprocal of -10.

Using the point-slope formula, we get:

y - 7 = (1/10)(x - 5)

Answer:

B: 5 + 4x < 24

Step-by-step explanation:

Answer:

The answer is B) 4x+5 < 24

Let the number = x

Writing the equation you have:

10x + 15 <= -17

Solve for x

Subtract 15 from both sides:

10x <= -32

Divide both sides by 10:

X <= -32/10

Simplify:

X <= -16/5 as a fraction or -3.2 as a decimal

Answer:

{ x ≠ ±6 ∪ x ≠ ± 6}

Step-by-step explanation:

x cannot be zero even though x can be cancelled in this expression.  Furthermore, x^2 - 36 cannot be zero, and thus x ≠ ±6.

Domain is { x ≠ ±6 ∪ x ≠ ± 6}

Answer:

21

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes. This means they have opposite signs (negative) and their numerators and denominators are switched ( reciprocal).

For example, these slopes are perpendicular:

3/2 and -2/3

(3/2--negate--> -3/2---> reciprocal--> -2/3)

Therefore, the answer is B.  The slope of one line must be the negative reciprocal of the other for the two to be perpendicular.

Answer:

[tex]-4(a + b = 6)[/tex]

Step-by-step explanation:

Given

[tex]a + b = 6[/tex]

[tex]4a + 2b = 19[/tex]

Required

Eliminate a

Multiply the first equation by -4

[tex]-4(a + b = 6)[/tex]

Add to the second equation

[tex]-4(a + b = 6) + (4a + 2b = 19)[/tex]

Solve brackets

[tex](-4a -4b = -24) + (4a + 2b = 19)[/tex]

Open bracket

[tex]-4a + 4a -4b + 2b = -24 + 19[/tex]

[tex]-4b + 2b = -24 + 19[/tex]

At this point, a has been eliminated;

From the list of given options, the option that answers the question is [tex]-4(a + b = 6)[/tex]

one pump, let's call it A, fills the reservoir by 1/60 every hour. Now, B fills it by 1/80 every hour. C empties it by 1/90 every hour. All three are on, so now we combine them into one function: t(1/60 + 1/80 - 1/90) = 1, where t = the time it takes to fill it, and 1 is just our "reservoir finally filled" marker.

isolate t onto one side and we see t = 720/13 exactly, or approximately 55.38 hours. let me know if this is the wrong answer but I'm pretty sure it is correct!

Answer:

1/time needed = 1/time of 1st pump + 1/time of 2nd pump - 1/time of 3rd pump

1/t = 1/t1 + 1/t2 - 1/t3

1/t = 1/60 + 1/80 - 1/90

1/t = 12/720 + 9/720 - 8/720

1/t = 13/720

t = 720/13 hours = 55.38 hours = 55 hours 23 minutes

Answer: Correlation without causation.

Correlation with causation: the number of high school seniors and high school graduates

Step-by-step explanation:

Correlation is a term that tells there is a relationship between two quantities.

Causation is a relationship where one quantity is affected by the other.

The number of graduates completely depends on the number of high school seniors.

So, the relationship between the number of high school seniors and high school graduates is a causation.

There is no relation between the amount of snowfall and the number of voters.

The number of nurses depends on the number of doctors but not completely.

It may be possible that the number of nurses will not increase with an increase in the number of doctors in a particular hospital.

So, there is a correlation without causation between the number of doctors and the number of nurses.

Answer:

correlation without causation is the number of doctors

and the number of nurses

correlation with causation is the number of high school seniors

and high school graduates

Step-by-step explanation:

the third picture shows symmetry and equality

Answer:

It's the third picture.

Step-by-step explanation:

This shows the reflection in m.

Answer:

y +4= -3 ( x-3)

Step-by-step explanation:

The point slope form of a line is

y-y1 = m(x-x1)

The point requested is (3,-4)

y - -4= m ( x-3)

y +4= m ( x-3)

The slope of the line  is positive since it goes from the top left to the bottom right

The slope can be found from (0,5) and (3,-4)

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

    = (5 - -4)/(0-3)

    = (5+4)/(0-3)

    = 9/-3

    = -3

y +4= -3 ( x-3)

The slope in all answer choices is 3 or -3.

Since the line is going down, the slope is going to be negative (-3).

Point slope form: y - y1 = m(x - x2)

We are given a point in the question so use it to fill in the equation.

y + 4 = -3(x - 3)

Answer: Bonnie can make 40 treat bags. Each treat bag has three pieces of Candy A, 11 pieces of Candy B, and 13 pieces of Candy C.

Step-by-step explanation:

Since there's no number of student's in her child's class, I did this:

I found the common factors of 120, 440, and 520. And found out that the GCF (greatest common factor) is 40.

120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120.

440: 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440.

520: 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520.

After finding out that the GCF is 40, I took the numbers 120, 440, and 520, and divided them by 40.

120 divided by 40 = 3

440 divided by 40 = 11

520 divided by 40 = 13

Therefore Bonnie can make 40 treats bags with no candy pieces left behind.

Answer:

x - 2y + 6 = 0  

Step-by-step explanation:

Going from (-2, 2) to (4, 5), we see that x (the 'run') increases by 6 and that y (the 'rise') increases by 3.  Thus, the slope of the line through these two points is m = rise / run = 3/6, or m = 1/2.

Starting with the slope-intercept formula y = mx + b, and using the x and y values from the point (-2, 2), we get

2 = (1/2)(-2) + b, or 4 = -2 + 2b, or 6 = 2b, or b = 3.  Then the slope-intercept form of the desired equation is y = (1/2)x + 3.  To obtain the standard form, we multiply all three terms of this result by 2, obtaining 2y = x + 6, or

x - 2y + 6 = 0

Answer: C)  [tex](-\dfrac{1}{2},\dfrac{3}{2})[/tex]

Step-by-step explanation:

The given system of equations :

[tex]2(y-x) = 5+2x\ \ ...(i)\\\\ 2(y+x)=5-2y\ \ ..(ii)[/tex]

Simplify left side, we get

[tex]2y-2x=5+2x\Rightarrow\ 2y-4x=5\ \ ...(iii)\\\\ 2y+2x=5-2y\Rightarrow\ 4y+2x=5\ \ ...(iv)[/tex]

Multiplying 2 on equation (iii), we get

[tex]4y-8x=10\ \ ...(v)[/tex]

Subtracting (v) from (iv) , we get

[tex]2x-(-8x)=5-10\\\\\Rightarrow\ 2x+8x=-5\\\\\Rightarrow\ 10x=-5\\\\\Rightarrow\ x=-\dfrac{5}{10}=-\dfrac{1}{2}[/tex]

Put value of [tex]x=-\dfrac{1}{2}[/tex] in (v), we get

[tex]4y-8(-\dfrac{1}{2})=10\\\\\Rightarrow \ 4y+4=10\\\\\Rightarrow\ 4y=10-4=6\\\\\Rightarrow\ y=\dfrac{6}{4}=\dfrac{3}{2}[/tex]

hence, the solution to the system is [tex](x,y)=(-\dfrac{1}{2},\dfrac{3}{2})[/tex]

Add -3k and 4k

16 + k - 14

Subtract 16 - 14

Hope this helps :)

Answer:

k = -2

Step-by-step explanation:

I'm assuming you are trying to find the value of k. First, let's add the like terms together, because everything is on one side. -3k+4k is equal to k. Now 16 and 14. 16-14 is equal to 2. But, they are all on one side. Suppose we keep k on the left. We have to move two to the other side, and it turns into negative 2. Therefore, k is equal to -2.
