Answer:

(2, 18) and (-3, -7)

Step-by-step explanation:

y = 5x + 8                     Substitute the value for y into the second equation

-10x + 2y = 16

-10x + 2(5x + 8) = 16

-10x + 10x +16 = 16

       16 = 16  True  

These two equation are the same line. So pick one of the equation to check which ordered pairs are true solutions.

Using y = 5x + 8

(0, -6)         -5 = 5(0) + 8 ; -6 = 8  No

(-1, 9)           9 = 5(-1) + 8;   9 = -5 + 8 ;  9 = 3 No

(2, 18)          18 = 5(2) + 8;  18 = 10 + 8 = 18;  18 = 18    Yes

( -3, -7)         -7 = 5(-3) + 8;  -7 = -15 + 8;  -7 = -7    Yes

There was twice as much water in container B as container A at first. Then 1/6 of the water in container B is poured into Contai
JulsSmile [24]
Let be B = how much water is in container B;
A =  how much water is in container A;
B = 2A;
B - ( 1 / 6 )B = A + ( 1 / 6 )B + 1.8 ;
Then, 2A - ( 2A ) / 6 = A + ( 2A ) / 6 + 18 / 10 ;
2A - A / 3 = A + A / 3 + 9 / 5 ;
30A / 15 - 5A / 15 = 15A / 15 + 5A / 15 + 27 / 15 ;
30A - 5A = 15A + 5A + 27 ;
25A = 20A + 27 ;
5A = 27 ;
A = 27 / 5 ;
A = 5.4 liters;
B = 2 × 5.4 = 10.8 liters ;

Let y = load in pounds and x = length in feet. In two or more complete sentences, describe the relationship between the variable
Anastasy [175]
The load and distance can be used to calculate work. work is equal to the force or load applied multiplied by the distance. work is done when a force is applied to an object then it moves to the same direction of the force applied. so the relationship of x and y is w = xy, with the unit of lb ft

A mountain is 12,408 feet above sea level, and a valley is 175 feet below sea level. What is the difference in elevation between
KengaRu [80]

Answer:

The difference of <u>12,583 feet</u> in elevation between the mountain and the valley.

Step-by-step explanation:

Given:

A mountain is 12,408 feet above sea level, and a valley is 175 feet below sea level.

Now, to get the difference in elevation between the mountain and the valley.

As mountain is above sea level = 12,408 feet.

And valley is below sea level = 175 feet.

So, by adding we get the difference in elevation between the mountain and the valley:

12408\ feet +175\ feet

=12583\ feet.

Therefore, the difference of 12,583 feet in elevation between the mountain and the valley.
