Answer:

y = [tex]\frac{1}{3}[/tex]x + 1 [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

y = -3x - 1

1. Perpendicular line needs the opposite (reciprocal) of the slope.

             reciprocal of -3 is -1/3, slope 1/3.                    y = 1/3x + b

2. Now find the b (y-intercept).                                     1 = 1/3(-1) + b

                                                                                       1 = -1/3 + b

                                                                                 + 1/3  +1/3

                                                                                    1 1/3 = b

3. Answer         y = [tex]\frac{1}{3}[/tex]x + 1 [tex]\frac{1}{3}[/tex]

Answer:

  f(1) = -2

Step-by-step explanation:

Put 1 where x is and do the arithmetic.

  f(1) = -4·1 +2

  f(1) = -4 +2

  f(1) = -2

Step-by-step explanation:

Hope this helps!

Answer:

Look down below!

Step-by-step explanation:

Alright, so let's start solving this

1. First we are going to be placing the x one one side and the constants (or the regular numbers) on the other side.

How to do that?

Well, we can take -3x and 20 to their other sides.

The reason for this is that we don't want to have the value with x as a negative

So we do

-3x-4 = 20

+3x -20 -20+3x

You may not understand what was about but all I did was just added 3x to both sides and subtracted 20 to both sides to make the new equation

-24 = 3x or 3x = -24

Now we can see that the x has a number it is being multiplied with so to get rid of the number we divide everything by 3

So

3x/3 = -24/3

Which results in x = -8 and voila, there is your answer!

Answer:

  (2/3)(e^t +1)^(3/2)

Step-by-step explanation:

Use the substitution ...

  u = e^t +1

Then du = e^t and you are finding the integral of ...

  ∫u^(1/2)·du

which you know by the power rule is ...

  (2/3)u^(3/2) = (2/3)(e^t +1)^(3/2)

While it’s possible to create a dot plot using this data, plotting 50 points on a number line is cumbersome. The more data points there are, the more tedious it is to make a dot plot. For this case, it might be better to use a different visual representation.

Answer:

200 + 28= 228

..................

The values of the numbers in the boxes is 57 x 4 = 200 + 28 = 228

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first number be represented as p

where the value of p = 57

Let the second number be represented as q

where the value of q = 4

And , A = 57 x 4

where the blank spaces in the boxes are by distributive property and

A = 57 x 4

( 50 + 7 ) 4 = ( 50 x 4 ) + ( 7 x 4 )

On simplifying the equation , we get

A = 200 + 28

A = 228

Therefore , the value of A is 228

Hence , the expression is A = 228

Answer:

Answer:

B

y=2x+4

Step-by-step explanation:

The y-intercept is 4, as the line passes through the y-axis only once, and at (0,4)

The format of a linear graph is y=mx+b where m is the slope and b is the y-intercept.

You can already tell that B is the only one with the y-intercept of 4.

The slope can be calculated quite easily, as we will start from (0,4) and make our way up to the next easily discernible point. The next most easily point seen is (2,8) so we will use the slope equation to find the slope. The equation is more or less like y2-y1  over x2-x1.

The y2 and x2 would be the (2,8) point because that is the second point on the line we are using. The x1 and y1 would be the first point (0,4). Now we will fill in the equation, which will look like 8-4  over 2-0  which will be 4 over 2, simplified to 4/2 and 2/1, being equal to 2.

The slope/m will be equal to 2, so the equation will look like

y=2x+4

Answer:

We know that:

csc(x) = 1/sin(x)

Now we want to work with:

2csc(x+y)

The first step is:

2csc(x+y)= 2/sin(x-y)

This is correct so far.

Now we need to use the relation:

sin(a + b) = sin(a)*cos(b) + sin(b)*cos(a)

Then:

sin(x - y) = sin(x)*cos(-y) + sin(-y)*cos(x)

sin(x) is an odd function, then: sin(-y) = -sin(y)

and cos(x) is an even function, then:

cos(-y) = cos(y)

Then we get:

sin(x - y) = sin(x)*cos(y) - sin(y)*cos(x)

then:

2/sin(x-y) = 2/(sin(x)*cos(y) - sin(y)*cos(x))

Now let's look at what she did:

2/sin(x-y) = 2/(cos x cos(-y)+sin xsin(-y))

Here is her error, she replaced:

sin(x - y) by cos x cos(-y)+sin(x)sin(-y)

This relation is for the cosine function, not the sine one, so here is her mistake.
