Answer: 0/9

Step-by-step explanation: Hi there!

First, we have to put the points into the y2-y1/x2-x1 form.

Take the y value from the second point (-8) and the first point y value (-8)

and subtract.

-8 - (-8)

to get 0

Now we have to get our denominator by taking the x value from our second point and subtracting it by our first y point.

7 - (-2)

to get 9

so when we put that together...

we get 0/9

So the answer is 0/9.

Hope this answer helps you!

Answer:

The number of pink pens can be 19 .

Step-by-step explanation:

Total Number of pens = 20

Let x be the number of pink pens

We are supposed to find If the probability of choosing a pink pen is close to 1, how many pink pens would you expect to see in Amanda's bag

Probability of choosing a pink pen = [tex]\frac{\text{Number of pink pens}}{\text{Total Number of pens}}[/tex]

Probability of choosing a pink pen =[tex]\frac{x}{20}[/tex]

ATQ

[tex]\frac{x}{20}[/tex]≈1

x≈20

So, the number of pink pens can be 19 .

Answer:

OMG yessss

Step-by-step explanation:

Given:

Three equations are

[tex]6(0.5x-1.5)+2x=-9-(x+6)[/tex]

[tex]4(0.5x-2)+3x=-14-(x+6)[/tex]

[tex]8(0.5x-3)+4x=-9-(x+6)[/tex]

Three solutions are [tex]x=-2,x=-1,x=1[/tex].

To find:

The solution of each equation from the given solutions.

Solution:

We have,

[tex]6(0.5x-1.5)+2x=-9-(x+6)[/tex]

Using distributive property, we get

[tex]3x-9+2x=-9-x-6[/tex]

[tex]5x-9=-15-x[/tex]

Isolate variable terms.

[tex]5x+x=-15+9[/tex]

[tex]6x=-6[/tex]

Divide both sides by 6.

[tex]x=-1[/tex]

Similarly,

[tex]4(0.5x-2)+3x=-14-(x+6)[/tex]

[tex]2x-8+3x=-14-x-6[/tex]

[tex]5x-8=-20-x[/tex]

[tex]5x+x=-20+8[/tex]

[tex]6x=-12[/tex]

[tex]x=-2[/tex]

Now,

[tex]8(0.5x-3)+4x=-9-(x+6)[/tex]

[tex]4x-24+4x=-9-x-6[/tex]

[tex]8x-24=-15-x[/tex]

[tex]8x+x=-15+24[/tex]

[tex]9x=9[/tex]

[tex]x=1[/tex]

Therefore, the solutions of given equations [tex]6(0.5x-1.5)+2x=-9-(x+6)[/tex], [tex]4(0.5x-2)+3x=-14-(x+6)[/tex] and [tex]8(0.5x-3)+4x=-9-(x+6)[/tex] are x=-1, x=-2 and x=1 respectively.

Answer: -18

Step-by-step explanation:

Answer:

W perimeter = 40

Step-by-step explanation:

All the sides of the squares equal the same amount.

If the perimeter of R is 28 divide 28 by 4 to give you 7.

And to get the area of a square you do length x width

So T would be 3 x 3 = 9

And it you add up 7 + 3 the sides on R and T = 10

So the left side on square W = 10

To get the perimeter multiply 10*4 = 40

I'm 90% sure, but hope this helps!!!

Answer:

-6 < x < 2

Step-by-step explanation:

-2|2x+4|+10>-6

Subtract 10 from each side

-2|2x+4|+10-10>-6-10

-2|2x+4|>-16

Divide by -2, remembering to flip the inequality

-2/-2|2x+4|>-16/-2

|2x+4|<8

We have two solutions, one positive and one negative( remember to flip the inequality)

2x+4 < 8    and 2x+4 > -8

Subtract 4 from each side

2x+4-4 < 8-4    and 2x+4-4 > -8-4

2x < 4             and   2x > -12

Divide by 2

2x/2 < 4/2             and   2x/2 > -12/2

x <2                and           x > -6

-6 < x < 2

Answer:

x<2 and x>-6

Step-by-step explanation:

First, get rid of anything on the outside of the absolute value bars. Subtract the 10 on both sides first.

-2|2x+4|+10>-6

             -10  -10

-2|2x+4|>-16

Now, divide by -2 on both sides.

-2|2x+4|>-16

/-2           /-2

|2x+4|<8

Just so you know, any time you multiply or divide by a negative, flip the inequality sign. Now because the numbers in the absolute bars are by themselves, you can start to finally solve. But, when you have an equation with absolute bars and you have the numbers in the absolute bars by themselves, you always have to split it into two equations. The equations have to be identical, but the number on the opposite side of the x has to be negative. Now, you solve both equations just like regular ones. Also, flip the sign for the inequality with the negative number.

|2x+4|<8    and     |2x+4|>-8

     -4  -4                     -4  -4

2x<4                      2x>-12

/2  /2                      /2   /2

x<2          and          x>-6

I hope this helps you out!!! Have an amazing day C:

Answer:

Jack Barlow

Step-by-step explanation:

Answer:

r=32/7

Step-by-step explanation:

Let's solve your equation step-by-step.

Step 1: Simplify both sides of the equation.

1/2r + 2 (3/4r - 1) = 1/4r + 6

Step 1: Simplify both sides of the equation.

1/2r + 2 (3/4r - 1) = 1/4r + 6

1/2r+(2)(3/4r)+(2)(-1)=1/4r+6(Distribute)

1/2r+3/2r+-2=1/4r+6

(1/2r+3/2r)+(-2)=1/4r+6(Combine Like Terms)

2r+-2=1/4r+6

2r-2=1/4r+6

Step 2: Subtract 1/4r from both sides.

2r-2-1/4r=14r+6-14r

7/4r-2=6

Step 3: Add 2 to both sides.

7/4r-2+2=6+2

7/4r=8

Step 4: Multiply both sides by 4/7.

(4/7)*(7/4r)=(4/7)*(8)

r=32/7

Answer: r=32/7

Step-by-step explanation:

Answer: D. Matthew’s, Rhoda’s, and Ming’s

Step-by-step explanation:

√0.89 ≈ 0.94

Anyah is incorrect because both of her decimals are smaller than √0.89.

Matthew is correct because 0 is less than 0.89 but 1 is still greater than 0.89.

Rhoda is correct because 0.9² is 0.81 is less than 0.89 but 1.0² is 1 which is still greater than 0.89.

Ming is correct because 0.93² is about 0.87 which is less than 0.89 but 0.95² is about 0.9 which is still greater than 0.89.
