Step-by-step explanation:

Answer:

6÷2×3=3×3=9

Step-by-step explanation:

6÷2×3

3×3

9

First let's add 6x to both sides. We do this because the 6x is negative and by adding 6x to both sides, we are isolating the 11 and we are also making the 6x positive, which makes things easier later.

-6x + 11 = -7

+6x          +6x

11 = -7 + 6x

Now let's flip the equation to make it easier to read:

-7 + 6x = 11

And let's add 7 to both sides as we need to isolate the 6x. We are adding 7 because the 7 is negative.

6x = 18

And finally to get the value of x we divide both sides by 6:

x = 3

Answer:

The midpoint of XY is point

M(�12, 5). If the coordinates

of X are (3, �3), what are the

coordinates of Y ?

----

Each coordinate of the midpoint is the average

of the corresponding endpoint coordinate.

----

Solve:

Let the coordinates of Y be (x,y)

---

(3+x)/2 = -12

3+x = -24

x = -27

----

(-3+y)/2= 5

-3+y=10

y = 13

---

Coordinates Y: (-27,13)

Answer:

$11.36 (11 dollars and 36 cents).

Step-by-step explanation:

This scenario can be written as the linear equation: y = -$0.16x + $20 Where y is the remaining credit, and x is the minutes spend calling.

To find the remaining credit after 54 minutes,

substitute 54 for x and simplify.

So y = -$0.16(54) + $19.60 = -$8.64 + $20.00 =

$20.00 - $8.64 = $11.36.

_________________________

If you want to solve this problem from scratch, first find the constant rate of money by subtracting 30 minutes (time) over $15.20(total) by 46 minutes over $12.64(total).

Just subtract across, and simplify to get the rate, and then apply that rate between the missing total of 54 minutes and the total of $12.64 dollars for 46 minutes. This is because rate = change quantity/change in time. If that rate is constant as it is in this relationship where the quantity is the amount of anything that is dependent on something, in this case it's money.

So subtract (find the difference) to find the pattern of change between these values in respect to time.

15.20/ 30 - 12.64 / 46 = 2.56 / -16 = 1.28 / -8 = 0.64 / -4 = 0.32 / -2 = 0.16 / -1 = -0.16 [This is the rate decrease in money every minute of a call being made or decrease in remaining credit every minute ].

Now since we know the rate, we can solve the missing factor of the problem by multiplying the rate by the change in time to get the change in quantity.

So : 54 - 46 = 8. 8 × 0.16 = 1.28 [This is the change in quantity from 46 to 54 minutes of calling ].

Therefore, $12.64 [remaining credit from 46 minutes ] - $1.28 [the change of credit from 46 minutes to 54] = $11.36 [remaining credit from 54 minutes].

Also in general, Rate = dependent variable / independent variable.

Answer:

To figure out the variance, divide the sum, 82.5, by N-1, which is the sample size (in this case 10) minus 1. The result is a variance of 82.5/9 = 9.17. Standard deviation is the square root of the variance so that the standard deviation would be about 3.03.

Answer:

4/3

Step-by-step explanation:

I used a site and my calculator

4 times 1/3 in fraction form is 4/3.

To multiply a whole number by a fraction, we multiply the whole number by the numerator of the fraction and keep the denominator the same.

In this case, we want to multiply 4 by 1/3:

4 × (1/3)

= (4 × 1) / 3

= 4/3

Therefore, 4 times 1/3 in fraction form is 4/3.

Step-by-step explanation:

if u subtract from a negative it is the same as adding a positive. So instead of 23 - (-34) you should do the equation 23 + 34 which equals 57.

Answer:

Rate of change/slope: 35

Miles at 10 hours: 350

Step-by-step explanation:

We can find the rate of change or the slope by using the slope formula below:

m = (y2-y1)/(x2-x1) where m is the slope

To find the slope, we can choose any two points from the table. I will choose (2,70) and (4,140)

m = (140-70)/(4-2)

m = 70/2

m = 35

The rate of change is 35 miles per hour

To find the miles at 10 hours, we can use the equation y = mx + b which is the equation of the line in slope intercept form. However, we will need to find the value of b. To do that, we can plug in any point from the table to find the value of b. I'll choose (2,70).

y = mx + b

70 = 35(2) + b

70 = 70 + b

b = 0

So the equation of the line would be y = 35x. Using this equation, we can find the number of miles at 10 hours:

y = 35(10)

y = 350

The number of miles at 10 hours is 350 miles

Answer:

x = [tex]\sqrt{21}[/tex]

Step-by-step explanation:

AC² = AB² + BC²

BC² = 3² + x² = 9 + x²

AB² = 7² + x² = 49 + x²

But AC² = (7 + 3)² = 100

∴ 100 = 49 + x² + 9 + x²

2x² + 58 = 100

x² = 50 - 29 = 21

x = [tex]\sqrt{21}[/tex]

Answer: the answer is the square root of 21.

Step-by-step explanation:

What I did was I just multiplied 7 times 3 and got 21 and that was the answer.
