Well a interger is any negative number so -1 or -2 or -3 or -4......
Answer:
I think it should be 
Step-by-step explanation:
When the question said area of the cube, I think it was supposed to be surface area, which would
where a is the length of one edge. Given that the length of one edge is 2x, we would plug in 2x to the equation to get
which would become
.
Let the time he spent bicycling at 11 mph be x and the time spent bicycling at 15 mph be y, then
x + y = 60 . . . (1)
7x + 11.75y = 600 . . . (2)
(2) x 7 => 7x + 7y = 420 . . . (3)
(2) - (3) => 4.75y = 180
y = 180 / 4.75 = 38
x = 60 - 38 = 22
Therefore, he should bicycle 22 minutes at 11 mph and 38 minutes at 15 mph.
Answer:
The slope of the line m = 1
The equation of the straight line x -y -7=0
Step-by-step explanation:
<u><em>Explanation:-</em></u>
In the given graph
The points are ( 7,0) and ( 0, -7)
The slope of the line

The equation of the straight line passing through the point (7,0) and slope m=1
y - y₁ = m (x - x₁)
y - 0 = 1( x-7)
y = x -7
x - y -7=0
<u><em>Final answer:-</em></u>
The slope of the line m = 1
The equation of the straight line x -y -7=0
<u><em></em></u>
I am pretty sure it’s y=1
