Answer:

Hence option b is correct.

( b. y = (2/3)x-3)

Step-by-step explanation:

Muriel says she has written a system of two linear equations that has an infinite number of solutions.

The first equation is given as:

3y= 2x -9.

This equation could also be written as:

y=(2/3)x-3

since we divide both side of the equation by 3.

<em>" The system of equation is said to have infinite solution if both the equations represents the same line "</em>

Hence, option b is correct.

( b. y = (2/3)x-3 )

An infinite number of solutions means a coincident line...it is the same line
3y = 2x - 9...divide by 3
y = 2/3x - 3...hmm...same line as answer choice b....they are coincident lines and have infinite solutions

This table shows temperatures in an Arctic city during
ioda

According to the temperature changes, it is found that:

  • On Tuesday, the temperature at Noon was of -28.5 ºF.
  • On Wednesday, the temperature at Midnight was of -5.5 ºF.
  • On Thursday, the change was of -11.8 ºF.
  • On Friday, the temperature at Noon was of -4.5 ºF.

<h3>What is the temperature change?</h3>
  • The temperature change during a period is given by the <u>temperature at the end of the period subtracted by the temperature at the start of the period</u>.

On Tuesday:

  • At the start of the period, the temperature was of -17.5 ºF.
  • The change was of -11 ºF.

Hence:

-11 = T_N - T_M

-11 = T_N + 17.5

T_N = -28.5

On Tuesday, the temperature at Noon was of -28.5 ºF.

On Wednesday:

  • At the end of the period, the temperature was of 10 ºF.
  • The change was of 15.5 ºF.

Hence:

15.5 = 10 - T_M

T_M = -5.5

On Wednesday, the temperature at Midnight was of -5.5 ºF.

On Thursday:

  • At the end of the period, the temperature was of -24 ºF.
  • At the start of the period, the temperature was of -12.2 ºF.

Hence:

C = -24 - (-12.2) = -24 + 12.2 = -11.8

On Thursday, the change was of -11.8 ºF.

On Friday:

  • At the start of the period, the temperature was of -21.8 ºF.
  • The change was of 17.3 ºF.

Hence:

17.3 = T_N - T_M

17.3 = T_N + 21.8

T_M = -4.5

On Friday, the temperature at Noon was of -4.5 ºF.

What is the area of the kite?
Kazeer [188]

Multiply 4.93m by 8.5m to get 41.905m to the second power.

You do this because there are 2 identical triangles on the top. And if you put those two triangles together, you get a rectangle. The length of the rectangle is 8.5m while the width would be 4.93. Multiplying the length and width gives you the area.

Then multiply 10.2m by 8.5m to get 86.7m to the second power.

You do this because there are 2 identical triangles on the bottom. And if you put those two triangles together, you get another rectangle. The length of the rectangle is 8.5m while the width would be 10.2m. Multiplying those together gives you the area.

You then add the two areas, 41.905m to the second power and 86.7m to the second power, to get the area of the entire figure.

After adding, you get 128.605 m to the second power. That's the answer
