Answer:

I love Math anyways

The ans is in the picture with the  steps how i got it

(hope this helps can i plz have brainlist :D hehe)

Step-by-step explanation:

You asked "How do you identify proportional relationships?"

It would be by determining whether two quantities are in a proportional relationship.

Answer:

1: x = 10

2: x = 2

3: x = 5

4: x = -5

Step-by-step explanation:

Answer:

48

Step-by-step explanation:

B and C trisrct AD so

that means that

AB=BC=CD

M is the midpoint so AM =MD

M is also the midpoint of BC also so if MC equal 8 l, BM equal 8. We add 8 and 8 together to find the value of BC which equal 16. Since BC equal 16 and it trisects AD, AB equal 16 and CD equal 16. Add all together and we get 16+16+16=16×3=48

- [tex]\frac{1}{14}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{2}[/tex] × - [tex]\frac{1}{7}[/tex] ( multiply numerators and denominators together )

= - [tex]\frac{1(1)}{2(7)}[/tex]

= - [tex]\frac{1}{14}[/tex]

Answer:

           [tex]\bold{f(\frac{7\pi}6)=-1}[/tex]

Step-by-step explanation:

[tex]f(\frac{7\pi}6)=2\sin(\frac{7\pi}6)=2\sin(\frac{7\pi}6)=2\sin(\pi+\frac{\pi}6)=-2\sin(\frac{\pi}6)=-2\cdot\frac12=-1[/tex]

part b (2,-1)

Part c the lines intersect at (-20,-45)

Step-by-step explanation:

Answer:

The equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

In our case, we are given

The slope m = -1/2

Point (2, -3)

now substituting m = -1/2 and (2, -3) in the slope-intercept form of the line equation to determine the y-intercept

[tex]y = mx+b[/tex]

-3 = -1/2(2) + b

-3 = -1 + b

b = -3 + 1

b = -2

now substituting m = -1/2 and b = -2 in the slope-intercept form of the line equation

y = mx + b

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

y = -1/2x - 2

Therefore, the equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:

Answer:

5) 3/19

6)9/19

Step-by-step explanation:

there are 19 marbles altogether

Answer:

It should be 9/19

Step-by-step explanation:

since you have the option to draw a red or blue you add those numbers together. So it's asking what is the probability of drawing either marble.

Answer:

Product of a Power: When you multiply exponentials with the same base, you add their exponents (or powers). Power to a Power: When you have a power to a power, you multiply the exponents (or powers). Quotient of Powers: When you divide exponentials with the same base, you subtract the exponents (or powers).

Step-by-step explanation:

Answer:

What is the Power rule?

The Power rule tells us how to differentiate expressions of the form x^nx

n

x, start superscript, n, end superscript (in other words, expressions with xxx raised to any power):

\dfrac{d}{dx}x^n=n\cdot x^{n-1}

dx

d

x

n

=n⋅x

n−1

start fraction, d, divided by, d, x, end fraction, x, start superscript, n, end superscript, equals, n, dot, x, start superscript, n, minus, 1, end superscript

Basically, you take the power and multiply it by the expression, then you reduce the power by 111.

Example: What is the derivative of x2 ?

For x2 we use the Power Rule with n=2:

The derivative of x2 = 2x(2-1)

= 2x1

= 2x

Answer: the derivative of x2 is 2x

Answer:

Please check the explanation.

Step-by-step explanation:

The slope-intercept form of the linear function  

[tex]y = mx+b[/tex]

where

The graph of y = mx + b is a straight line. Thus, y = mx + b represents a linear function.

Analzing the function y = –x + 5

Given the linear function

y = –x + 5

comparing with the slope-intercept form of linear equation

The slope m = -1

The y-intercept b = 5

Also, the graph of a linear function is a straight line.

Thus,

The function  y = –x + 5 represents  a linear function.

Analzing the Table Function

x        0     1     2     3

y        0     1     8     27

In order to identify whether the given table represents the linear function or not, we need to make sure the given function has a constant change x and y.

If there is a constant change in x and y, then it would be a linear Function otherwise it would not represent a linear function.

There is a constant change in x values.

i.e.

1 - 0 = 1

2 - 1 = 1

3 - 2 = 1

But, there is NOT a constant change in y.

i.e.

1 - 0 = 0

8 - 1 = 7

27 - 8 = 19

It is clear that the table does not have a constant change in y-values.

Therefore, the table function does not represent the linear function

Answer:

C) B>A

Step-by-step explanation:

if it doesn't make sense think of it like the number in between A and B is .5. You can visibly see that A is less than or below .5 and B is above or greater than .5, so B is greater than A.

Answer:

all of them?

Step-by-step explanation:

Answer:

x=1, y=1.

Step-by-step explanation:

From the second equation:

x = 8 - 7y, so substituting for x in the first equation:

3/8(8 - 7y) + 1/3y = 17/24

3 - 21/8 y + 1/3y = 17/24

1/3y - 21/8y = 17/24 - 3

Multiply through by 24:

8y - 21*3 y = 17 - 72

8y - 63y = -55

-55y = -55

y = 1.

And  substituting for y in the second equation:

x + 7(1) = 8

x = 8 - 7

x =  1.

Answer:

B

Step-by-step explanation:

the line has no slope

y = 5

Answer:

b

Step-by-step explanation:

Answer:

Step-by-step explanation:

slope intercept form is y=mx+b

(-1/2)x +y= 10; add to both sides (-1/2)x

y= (1/2)x +10
