Answer:

Suppose~the~two~numbers~are~x~and~y.\\From~the~first~condition,\\x+y=-17...........(1)\\From~the~second~condition,\\x-y=41.............(2)\\Adding~eq^n(1)~and~eq^n(2),~we~get,\\x+y+x-y=-17+41\\or, 2x = 24\\or, x=12\\Substituting~x=12~in~eq^n(2),\\y = -17-x = -17-12 = -29

So,~the~two~numbers~are~12~and~-29.

The scatter plot shows the amount of sleep Aria got the night before a test and her test scores. Use the points (0, 62) and (6,
Minchanka [31]

Answer:

y = 3x + 62

Step-by-step explanation:

Using the points :

(0, 62) and (6, 80)

Equation of trend line is in the form:

y = mx + c

Where m = slope ; c = intercept

Slope (m) = (y2 - y1) / (x2 - x1)

m = (80 - 62) / (6 - 0)

m = 18 / 6

m = 3

Intercept, c = value of y when x = 0

From (0, 62)

x = 0 ; y = 62

Then c = 62

Hence,

y = 3x + 62

Could somebody please help me find the answers for 'x' for these pictures?
lesya692 [45]

Answer:

Pic 1: x=31

Pic 2: x=20

Step-by-step explanation:

<u>Picture 1:</u>

<u />2x+x-3=90\\3x-3=90\\3x=93\\x=31

First, add the 2x and x together for 3x

Then add 3 to both sides of the equation

Finally, divide each side by 3.

<u>Picture 2:</u>

<u />7x+x+20=180\\8x+20=180\\8x=160\\x=20<u />

First, add 7x and x together for 8x

Then, minus 20 from both sides of the equation

Finally, divide each side by 8.

Which of the following ordered pairs represents the solution to the system given below?
castortr0y [4]
X − 4y = 7
5x + 9y = 6

5x − 20y = 35  //1st * 5
5x + 9y = 6

5x +9y - 5x + 20y = 6 - 35  //2nd - 1st
5x + 9y = 6

29y=-29
5x=6-9y

y=-1  //1st : 29
5x=6-9*(-1)

y=-1
x=15:5 //2nd : 5

y=-1
x=3

check:
for x=3 and y=-1 there is:
x − 4y = 7 is 3 − 4*(-1) = 7 is 7=7 ok
5x + 9y = 6 is 15-9=6 is 6=6 ok

answer: (3;-1) represents the solution.
