7. Which graph represents a proportional
relationship

PLEASE HELP ME

Answer:

A= 5/7b +8

Step-by-step explanation:

The basic idea is that you can do anything you want (except divide by

zero) to either side of the equation, so long as you do the same thing

to the other side, too.

Step-by-step explanation:

6x-4x=2x=7-1=6

2x=6

-2x-2x=x 6/2x=3

x=3

Answer:

[tex]\frac{2}{3} x-13[/tex]

Answer:

x/3 = 6/9

3 x 2 = 6

3 x 3 = 9

x = 2

Answer:

The answer is "[tex]\angle y = 90^{\circ}[/tex]"

Step-by-step explanation:

Please find the image file of the angle in the attachment.

Each line is 180° straight because the [tex]\angle x[/tex]-axis of the 40° and 50° angles is a straight line:  

[tex]= \angle x + 40^{\circ} + 50^{\circ} = 180^{\circ}[/tex]

Use this formula and isolate x.

[tex]\angle x + 40^{\circ} + 50^{\circ} = 180^{\circ}\\\\ \angle x + 90^{\circ} = 180^{\circ} \\\\ \angle x = 180^{\circ} - 90^{\circ} \\\\ \angle x = 90^{\circ}\\\\[/tex]

Since the two are vertical angles, they have the same measurement. These have the same measurement.  If [tex]\angle x = 90^{\circ}[/tex] and [tex]m \angle x = m \angle y[/tex], then  [tex]\angle y = 90^{\circ}[/tex]

Answer:

there is 74 quarters

Step-by-step explanation:

$17.75 divided by 25 equals 71 and there is stillb75 left how many quarters are in that 3 quarters so 71 plus 3 equals 74

Answer:

The slope would be 1/2.

Step-by-step explanation:

Step one: Subtract 2x from both sides to get, -4y=-2x+18

Step two: Divide -4 from all sides

It is just that simple. Hope this helps. Have an awesome day!!!!!!!

Answer:

8 + 3x ≤ 20

Step-by-step explanation:

Given

2 Games = $8

Additional Game = $3

Amount = $20

Required

Determine the inequality that represents the number of games

From the question, we understand that the minimum number of games that can be played is 2.

So, the expression can be:

Cost of 2 games + Cost of additional games ≤ Amount

This gives:

8 + 3 * x ≤ 20

Where x represents the additional number of games

By simplifying the expression, we have:

8 + 3x ≤ 20

Answer:

The probability is [tex]P( X > 12.10 ) =0.0004[/tex]

Step-by-step explanation:

From the question we are told that  

    The mean is  [tex]\mu = 11.95 \ ounce[/tex]

     The  standard deviation is  [tex]\sigma = 0.045 \ ounce[/tex]

 Generally the  probability that a bottle has more than 12.10 ounces poured into it, causing it to overflow is mathematically represented as

      [tex]P( X > 12.10 ) = P( \frac{X - \mu }{\sigma } > \frac{ 12.10 - 11.95}{0.045} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

     [tex]P( X > 12.10 ) = P( Z > 3.33 )[/tex]

From the z table  the area under the normal curve to the right corresponding to  3.33   is

     [tex]P( Z > 3.33 ) = 0.0004[/tex]

=>  [tex]P( X > 12.10 ) =0.0004[/tex]

12 ÷ 5/8

12 x 8/5

(12 • 8)/5

96/5

Done!

Answer:

The length is 20 m, the width is 10 m, and the area is 200 m.

Step-by-step explanation:

Here is why, since the length is 16 cm we first divide by 4 then multiply by 5. When we divide by 4 we get 4 and when we multiply by 5 to get 20. Then, we do the same for the width to get 10. Lastly, we just multiply both together.

Can I have brainliest?

Answer: Emily read 17 hours a week.

Step-by-step explanation: Divide the number of hours by weeks. 527/31=17

(I) is not necessarily true. Consider the function f(x) = - |x| on the interval [-1, 1]. There's a maximum at x = 0, but f' (0) does not exist.

But both (II) and (III) are true, so the answer is A.
