Im trying to do IXL and I dont understand the way my teacher teaches (ironic right?)
Can you please help?
the points (p,3) and (-4,-4) fall on a line with a slope of 1/2. What is the value of p?

Answer:

10 5 30

Step-by-step explanation:

Answer:

{4, 13}

Step-by-step explanation:

Represent the integers by I and J.  Then I + J = -17 and I*J = 52.

Let's solve this system using substitution.  Solve the first equation for I as follows:  

I + J = -17 becomes I = -J - 17

Substitute -J -17 for   I   in the second equation:

(-J - 17)*J = 52

Performing the indicated multiplication, we get:

-J^2 - 17J - 52 = 0

Let's solve this using the quadratic formula.  The quadratic coefficients here are {-1, -17, -52}, and so the discriminant, b^2 - 4ac, is

(-17)^2 - 4(-1)(-52), or 289 - 208, or 81.  This result is positive, so we know that the quadratic equation has two real, unequal roots.  They are:

      17 ± √81         17 ± 9

J =  --------------- = ---------------

         2(-1)                  -2

Evaluating this last result, we get J = (17 + 9)/2, or J = 13, and

J = (17 - 9)/2 = 8/2, or J = 4

Answer:

It's C) It's 1/2 bigger. It's the same rectangle just bigger. if you do the 3.86 - 1.93 you get 1.93

Answer:

4/5 OR 0.8

Step-by-step explanation:

Divide the distance between them by 5,280. You should then get a decimal of 0.8. Not sure if you are looking for decimal or fraction, but 0.8 as a fraction is 4/5. So 4/5 of a mile is in between their two houses. Hope this helps :)

Answer:

The bicyclist rides (64) miles in (4) hours.

Step-by-step explanation:

As you can see the 64 is on the Distance side, so that shows how far he or she travels.  Then you can see on the bottom of the graph it shows you time in hours. The point is at 4, so he or she travels 64 miles in 4 hours.

Hope this helped.

Answer:

8:05 pm (If you round to the nearest tenth place)

Step-by-step explanation:

basically, 4:00 pm and 5:10 pm have a 1 hour and 10 minute difference.

1 hour and 10 minutes divided by 65 miles is 1.6923076 or 1.7 minutes

1.7 minutes times 150 miles is 2 hours and 55 minuets

2 hours and 55 minutes plus 5:10pm is 8:05 pm

I'm so sorry if I'm wrong!

Answer: a) d(t) = [tex]\frac{13}{14}[/tex] (t - 70) + 65   b: 6:41 pm

duration of time passed:

5:10 pm - 4:00 pm = 70 mins

distance = 65 miles

you points to use to make an equation:

(0,0) and (70,65)  ---------------------> ( (0,0) is bc youre beginning the trip and you have no distance )

find the slope of your "future" equation

[tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{65}{70}[/tex] = [tex]\frac{13}{14}[/tex] = m

now use point-slope form

y - 65 =  [tex]\frac{13}{14}[/tex] (x - 70)

y=  [tex]\frac{13}{14}[/tex] (x - 70) + 65

and since it wants it in terms of d and t,

d(t) = [tex]\frac{13}{14}[/tex] (t - 70) + 65

part b:

150 =  [tex]\frac{13}{14}[/tex] (t - 70) + 65

85 = [tex]\frac{13}{14}[/tex] (t - 70)

85 = [tex]\frac{13}{14}[/tex] t - 65

150 = [tex]\frac{13}{14}[/tex] t

2100 = 13t

161.54 = t

about 162 minutes

Thennnn:

162/60 = 2 hours and 41 mins

4:00 pm + 2 hours and 41 mins = 6:41 pm

Answer:

EASY DUBS:

Step-by-step explanation:

2*x-((1/4)*y) = 1 // - 1

2*x-((1/4)*y)-1 = 0

2*x+(-1/4)*y-1 = 0

2*x-1/4*y-1 = 0 // + -1/4*y-1

2*x = -(-1/4*y-1) // : 2

x = (-(-1/4*y-1))/2

x = (1-(-1/4*y))/2

x = (1-(-1/4*y))/2

Answer:

2(19[tex]x[/tex]x  -11)

        0R

38x - 22

Step-by-step explanation:

QESTION: 18x – 4(9 – 5x) + 14

Rearrange terms that whould be -: 18x – 4(-5x + 9) + 14

Disterbot the one in brakect and the nagative four: – 4(-5x + 9)

SLOVE:  – 4(-5x + 9) ^^ 4 x 5 = 20 and 4 x 9 = 36 ^^ PUT THE ALL TOGETHER.

What you have now --> 18x + 20x - 36 + 14

Now, it's time to use your PEMDAS, we have Add and Subtract so you are going to do A fisrt (Add).

-36 + 14 = -22

Now you have, 18x + 20x - 22

Combine the like terms: 18x + 20x = 38x (don't forget the - 22)

38x - 22

2 x 19 = 38

2 x 11 = 22

What do you notice? ------- They all have 2 right? YES!, So put 2 in the front with parentheses, then put 19x and -11 in the parentheses.  

Here is your EQUATION!

2(19[tex]x[/tex]  -11)

Answer:

B.

Step-by-step explanation:

We know that (4 + x) is bigger than 6, so we have to find the answer that has more than 4.  Since A and B both have answers that are more than 4, those are our options.  But notice that A has one error, first lets define a closed circle and an open circle.  A closed circle can mean it is greater than or equal to, it can also mean that it is less than or equal to.  But an open circle means that it is either less than, or greater than.  And because the equation has an open circle ( which is this sign >) it means that the answer is option B.

Here is a better picture of what a close circle and open circle look like:

Answer:

6.6 inches

Step-by-step explanation:

4.1 times 3 = 12.3

2.2 times 3 = 6.6

I think this is right... sorry if not

Answer:

x = 6.6

Step-by-step explanation:

In order to solve the missing variable, we need to find the scale factor. I'll just take 12.3 and divide it by its corresponding side that is 4.1.

SF = 12.3/4.1 = 3

Now that we know the scale factor is 3, we can take 2.2 and multiply it by 3 to solve for x.

2.2(3) = 6.6

Therefore, x = 6.6.
