2) If Mike fell from (0.35) to (20, 0), determine the slope of his fall.​

Answers

Answer:

-7/4.

Step-by-step explanation:

I'll take it to mean (0, 35)

The slope = (y2-y1)/(x2-x1)

=  (0-35)/ (20-0)

= -35/20

= -7/4.

-7.4 is the answer I’m pretty sure

Estimate the solution to the system of equations.

Answers

Answer:

Find it in the explanation

Step-by-step explanation:

Equate the two solutions.

2x+3y=6 is exactly half of -4x+3y=12, so multiply 2x+3y=6 by 2.

Now we get

4x+6y=12 and

-4x+3y=12

Here what operation you use is your choice, but because I see a positive 4x and a negative 4x down below, I'm gonna use addition to cancel out the x.

Adding these two equations together, I get:

9y=24

y=24/9

in fraction form y= 2 and 2 thirds.

Plug that in any of the equations and solve for the value of x, which will be -1

Therefore, the coordinates are (-1, 2 and 2/3)

Answer:

The answer is x= -1/2 and y= 7/3 or 2whole 1/3.

What is the middle term of the product of (x - 4)(x - 3)?

Answers

Answer:

- 7x

Step-by-step explanation:

Given

(x - 4)(x - 3)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 3) - 4(x - 3) ← distribute both parenthesis

= x² - 3x - 4x +  12 ← collect like terms

= x² - 7x + 12

with middle term = - 7x

Answer:

Step-by-step explanation:

= x(x-3) - 4(x-3)

= x²-3x - 4x + 12

= x² -7x +12

So -7x is the middle term

Plz help me I do not understand this Plz show your work 4x-8=16

Answers

Answer:

x = 6

Step-by-step explanation:

First, add 8 to both sides.

4x - 8 = 16

4x - 8 + 8 = 16 + 8

4x = 24

Then, divide 4 from each side.

4x ÷ 4 = 24 ÷ 4

x = 6

Hope this helps.

Answer:

x = 6

Step-by-step explanation:

Well to solve for x in,

4x - 8 = 16

We use the commutative property which is the moving of numbers and variables to either side of the equation.

So 4x - 8 = 16

+8 to both sides

4x = 24

Divide 4 by both sides

x = 6

Thus,

x is 6.

Each new triangle shown below has one more dot per side than the previous triangle. What is the total number of dots on the 200th triangle of this sequence? first term has 6 second term has 9 third has 12 PLS HELP WILL MARK BRAINLIEST

Answers

Answer: 603 dots

Step-by-step explanation:

Triangle always has 3 sides. Given that

Each new triangle shown below has one more dot per side than the previous triangle. That means if first term has 6 dot, the second term will have 9 dots and third has 12 dots.

The difference between first and the second is the same with the difference between third and the second. That is,

First term a = 6

Difference d = 3

Number of term n = 200

This is arithmetic progression. We can come up with a formula:

Tn = a + ( n - 1 )d

Substitute all the parameters into the formula

Tn = 6 + ( 200 - 1 )×3

Tn = 6 + 199×3

Tn = 6 + 597

Tn = 603 dots

Therefore, the total number of dots on the 200th triangle of this sequence is 603 dots.

(I'll also need help on the shading for the fraction picture)

Answers

Answer:

4) 1/8

5) 56

6) 49

First shaded boxes = 4/7

Second shaded boxes = 1 out of 8 boxes are shaded = 1/8

Step-by-step explanation:

1/2x1/4=1/8

7X8=56

59-7=49

First shaded boxes = 4 out of 7 are shaded = 4/7

Second shaded boxes = 1 out of 8 boxes are shaded = 1/8

The fractional part of the game is left   [tex]\frac{7}{8}[/tex]  , total minutes of playing time 56 mins and playing time are left in the game is 49 mins .

What is fraction?

A fraction represents a part of a whole or, more generally, any number of equal parts.

According to the question

Jackson is attending a lacrosse game that is halfway through the first quarter

i.e,  Game played = [tex]\frac{1}{2} *\frac{1}{4}[/tex]

       Game played = [tex]\frac{1}{8}[/tex]  

a) fractional part of the game is left

Game left  = 1 -  [tex]\frac{1}{8}[/tex]  (treated complete game as 1 )

                 =    [tex]\frac{7}{8}[/tex]  

b)  If 7 minutes of playing time have past,  

i.e  [tex]\frac{1}{8}[/tex]  part of game is completed in 7 mins

therefore,

1 whole will complete in 7*8 = 56 mins

c) Minutes of playing time are left in the game

As,

total time to complete the game - game played time

=  56 -  7

= 49 mins

as in the fraction of shading question

a) [tex]\frac{4}{7 } is shaded[/tex]

b) [tex]\frac{1}{8}[/tex] is shaded

Hence , the fractional part of the game is left   [tex]\frac{7}{8}[/tex]  , total minutes of playing time 56 mins and playing time are left in the game is 49 mins .

Answer:

C: 13/32

Step-by-step explanation:

Change 1/4 and 1/8 into 4/32 and 8/32 and add them up with the 7/32 and then subtract the top and you have your answer

Answer:

13/32 left over.

Step-by-step explanation:

First, you would want to convert the 1/4 and 1/8 to ?/32. You would get: 7/32 on housing, 8/32 on food, and 4/32 on transportation.

To get those numbers this is what you do: 1/4 was spent on food. 32 divided by 4 is 8. So that would be 8/32. I hope you understand, because I'm not that good at explaining!

Then you add those up: 7/32 + 8/32 + 4/32. You would get 19/32 as your total, which means you have 13/32 left over. I hope this helped!
