Step-by-step explanation:

Answer:

b= 12.83

c= 7.17

Variable "c" is independent because it does not change. Jim receives $7.17 back.

Given:

Midpoint = (2,-14)

One endpoint = (4,-13)

To find:

The another endpoint.

Solution:

Let (a,b) be the another endpoint.

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Using midpoint formula, we get

[tex](2,-14)=\left(\dfrac{a+4}{2},\dfrac{b+(-13)}{2}\right)[/tex]

[tex](2,-14)=\left(\dfrac{a+4}{2},\dfrac{b-13}{2}\right)[/tex]

On comparing both sides, we get

[tex]2=\dfrac{a+4}{2}[/tex]

[tex]4=a+4[/tex]

[tex]4-4=a[/tex]

[tex]0=a[/tex]

And,

[tex]-14=\dfrac{b-13}{2}[/tex]

[tex]-28=b-13[/tex]

[tex]-28+13=b[/tex]

[tex]-15=b[/tex]

Therefore, the another endpoint is (0,-15).

Answer:

A

Step-by-step explanation:

The required system that can be obtained by substituting is

2 (1 - 2c) + 3c = 5, because a = 1 - 2c.

Given the system of equation;

2a + 3c = 5

a +2c=1

This system can be solved using the substitution method.

From equation 2:

Substitute equation 3 into 1 will give:

Hence the required system that can be obtained by substituting is

2 (1 - 2c) + 3c = 5, because a = 1 - 2c.

Answer: 2/7

Step-by-step explanation:

There are 7 letters in January, and 2 "a"s in order to find the probability, simply take 2/7. You can either leave it in the fraction form, or use the calculator, showing you have a 0.2857% chance of picking an "a"

2/7

there are 7 letters in jAnuAry and as you can see there are 2 A's so there is a 2/7 chance which is higher of a chance than the rest of the letters which are 1/7 each so it is most likely you would draw A although I can't fully say that because there is a 5/7 chance of drawing the other letters. Another way to say it is there is a 0.28571428571% chance of drawing A but there is a 0.71428571428% chance of drawing any other letter.

Answer:

[tex]t=\dfrac{d}{s}[/tex]

Step-by-step explanation:

Dan is driving with an average speed of s. He is driving a total distance of d.

The average speed of an object is given by :

Average speed = total distance/total time

Let b the time of his trip

So,

[tex]s=\dfrac{d}{t}\\\\or\\\\t=\dfrac{d}{s}[/tex]

So, the formula for the total time of his trip is [tex]\dfrac{d}{s}[/tex].

Answer:

2

Step-by-step explanation:

The average rate of change of h(x) in the closed interval [ a, b ] is

[tex]\frac{f(b) - f(a)}{b-a}[/tex]

Here [ a, b ] = [ - 2, 4 ] , then

f(b) = f(4) = - (4)² + 4(4) + 12 = - 16 + 16 + 12 = 12

f(a) = f(- 2) = - (- 2)² + 4(- 2) + 12 = - 4 - 8 + 12 = 0

Then

average rate of change = [tex]\frac{12-0}{4-(-2)}[/tex] = [tex]\frac{12}{6}[/tex] = 2

Answer:

170

Step-by-step explanation:

If you look at the other angle it says 20 and a whole circle would be 360 so subtract 360-130 then after that since the angle takes 2 part or however you may say that means u subtract 60 (20+20+20 thee open angle) this means you get 170 (i think im unsure but you can try)

Answer:

x² + (y + 8)² = 81

Step-by-step explanation:

Centre (h,k) = (0,-8)

radius (r) = 9

(x - h)² + (y - k)² = r²

(x - 0)² + (y + 8)² = 9²

x² + (y + 8)² = 81
