Answer:
Yes it is a rational number. (There are no explanations)
Step-by-step explanation:
The problem ask to calculate the slope of the line base on the diagram or table you give. To calculate the slope you must first know its formula and that is Rise/Run and also be Y/X so you must divide the Megabytes and the Minute and with that calculation the slope is 3.75 so the equation will be y=3.75x
Answer:
89
Step-by-step explanation:
1. She spent a total of 23 + 30 + 16 = 69 dollars.
2. That means she had at least 69 dollars to spend. But if it were 69 dollars, that would mean she had 0 remaining dollars because she spent it all.
3. But she had 20 dollars left after she spent the 69 dollars.
4. So that means she had 89 dollars before making the purchase
15(j - 3) + 3j < 45
15j - 45 + 3j < 45
18j < 45 + 45
18j < 90
j < 90/18
j < 5
1) Question 3
The system
y = 3.5x - 3.5
y = -3.5x +3.5
has one solution.
To find it, you can add the two equations:
2y = 0 => y =0
Now replace that value in any of the two original equations.
Doing it with the first of the equations:
=> 3.5x - 3.5 = 0=> 3.5x = 3.5 = x = 3.5 / 3.5 = 1
Solution (1,0)
Answer: one solution.
2) Question 4
<span>The graph of a system of equations will intersect at more than 1 point.
Some times:
For example:
y = x + 2
2y = 2x + 4
Intersects in infinite points.
y = x + 2
y = x + 3
will not intersect
y = 2x
y = x+1
will intersect at one point.
And a system with a quadratic equation and a linear equation may drive to intersection in two points.
