Algebra 1. I have no clue how to do this! Please explain!!!!!

Answer:

Answers A and B respectively

Step-by-step explanation:

In the first pic, they are asking you for the value of the function at the points x = -1 and x = 5. Then you are asked to subtract your results. When the value of 'x' is -1, the 'y' value is 3. When the value of 'x' is 5, the 'y' value is -4. Therefore:

[tex]f(-1)-f(5)=3-(-4)=7[/tex]

Answer A

For the second problem, they are saying that the line connecting points A and B is undefined. This means the slope is undefined along that line. An undefined slope is due to a zero in the denominator. Begin by taking the change in 'y' over the change in 'x' to get:

[tex]\frac{y_1-1}{x_1+2} =m[/tex]

In order for our slope 'm' to be undefined, set the denominator to zero and see at what 'x' value this occurs at:

[tex]x_1+2=0[/tex]

[tex]x_1=-2[/tex]

Then they say that the line connecting points C and D is zero. A zero slope would mean a zero in the numerator. Again, begin by taking the change in 'y' over the change in 'x' to get:

[tex]\frac{3-y_2}{-5-x_2} =m[/tex]

Set the numerator equal to zero to get:

[tex]3-y_2=0[/tex]

[tex]y_2=3[/tex]

Answer B

Answer:

the answer for the data chart should be 1,2  2,4  3,6  4,8 because it tells you that x is the time in minutes and y is the number of cookies that are cooked or baked out and that may be the answer for the x, y data chart part so thank you for helping you and give me brainliest if you want or not.

Answer:

I am saying 88

Step-by-step explanation:

It's the lowest number in the options.

Across the top: 8, 9, 2

Down the side: 4, 3, 6

8 x 4 = 32

9 x 4 = 36

2 x 4 = 8

4 x 8 = 32

3 x 8 = 24

6 x 8 = 48

Hope this helps!

Answer:

Answer is in the file/picture below

Step-by-step explanation:

To start, we can See that 4 times something makes 36, so we can do 36/4 to get 9. (Top 3rd slot)  4 times 9 equals 36.

Next, we can do the 4th slot at the top. We can see that 4 times something makes 8. So, we can do 8/4 to get 2.  2 times 4 equals 8.

Next, we can do the first slot in the third row. We can see that 8 times something equals 24. So we can do 24/8 to get 3.  8 times 3 equals 24.

Lastly, we can do the first slot in the bottom row. We can see that 8 times something makes 48. So, we can do 48/8 to get 6.  8 times 6 equals 48.

Answer:

84 cherry tomatoes

Step-by-step explanation:

If he is making 6 large salads and 4 small salads you need to add up the amount of tomatoes that are needed for each salad.

6 large salads - 10x6= 60

4 small salads - 6x4= 24

60+24= 84

Answer:

Mr. Wright's class: positively skewed
Mr. Chu's class: negaitvely skewed

Step-by-step explanation:

Answer:

24

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

If there are 8 sections, there is a 1 in 8 chance of getting each section. Consider multiples of 3 ⇒ 3, 6. And to spin that multiple 6 times, you need to multiply the number of sections by the number of multiples. The number of sections(nos) is 8, and the number of multiples(nom) is 3.

[tex]nos * nom = 24[/tex]

Answer:

24 is the correct answer.

Answer:

Try 27.

Answer:

D. m = 0 - y / 0 - x

Step-by-step explanation:

It is not a way of calculating the slope.

The other ways :

All of these methods represent the same way, but represented in different forms, to find the slope.

Hence, only D is not a way of calculating the slope.

1. [tex]1/4 * 4 = 1[/tex]

2. [tex]\frac{3}{4} * 8 = 6[/tex]

3. [tex]1\frac{1}{4} * 4 = 5[/tex]

4. [tex]1\frac{1}{2} * 2 = 3[/tex]

Answer:

A= (-7, -7)

B= (-3, 2)

C= (0, - 2)

Step-by-step explanation:

Answer:

just switch the two at the top

Part B: Lily walked 3 units up and 1 unit right to get from the park to the market.

===============

position of park: (2, 5)

If moved 3 units up. There will be change in y-axis. ⇒ (5+3) = 8

If moved 1 units right. There will be change in x-axis. ⇒ (2+1) = 3

So market position: (3, 8)

Answer:

if you go up 3 units that puts you at 2,8 then go over right 1 puts you at 3,8 which means x=3 and y=8

Answer:

533.3 MPH

Step-by-step explanation:

Because the round trip was divided into two segments with varying speeds, you can name the first one (480 MPH) x, and the second one, (600 MPH) y. Then you can use the formula 2xy/(x+y) and put the values in. You should get 576000/1080. After you solve it, you will get 533.333333333... But the problem has not been solved yet, because you have to round 533.33333... to the nearest tenth place, which is .3. Then you should get the answer 533.3 MPH.

Do you guys do RSM too?

576cm cubed

I think that is the answer

Answer:

66.56 cm

Step-by-step explanation:

to find the circumfrence of a full circle you use the equation 2[tex]\pi[/tex]r

as 8 cm is the radius you do  2*3.14*8 which = 50.24

then to find it of quarter of a circle

50.24/4 = 12.56

to find the half line parallel to 17 cm you do 17-8= 9

overall perimeter=

12.56+8+9+10+17+10 = 66.56
