The sum of two numbers is 18 and the difference is 8
Andrews [41]

Answer:

x = 13 and y = 5

Step-by-step explanation:

x + y = 18

x - y = 8

<u>Step 1:  Find y</u>

x = 18 - y

(18 - y) - y = 8

18 - y - y - 18 = 8 - 18

-2y / -2 = -10 / -2

<em>y = 5</em>

<em />

<u>Step 2:  Plug into x + y = 18 to get x</u>

x + 5 - 5 = 18 - 5

<em>x = 13</em>

<em />

Answer:  x = 13 and y = 5

What is the inequality represented by this graph? (pls help its worth 30 points and ill give brainliest if ur correct :D)
Yakvenalex [24]

Step-by-step explanation:

We find the equation of the solid blue line:

The line decreases by 1 unit for every 3 units across.

=> Slope of line = -1/3.

Also the y-intercept is 1.

=> Line equation: y = -1/3 x + 1.

We see that the graph below this line is shaded.

Therefore all y-values below or on the line are represented by the graph.

=> y <= -1/3 x + 1.

The answer is y <= -1/3 x + 1.

Write an equation for the line parallel to the line 5/8x−7/6y =2 through the point (7,−1).
LiRa [457]

y =  -  \frac{28}{48x - 15} -  \frac{125}{321}is the answer.

Step-by-step explanation:

For this question,

•<u> </u><u>First</u>, find the slope of the line parallel to the line 5/8x−7/6y=2 :-

m =  - \frac{28}{ - 15 + 48x}

•<u>Second</u>, find the equation of the line,

y =  -  \frac{28}{48x - 15} -  \frac{125}{321}
