Answer:
No solutions
Step-by-step explanation:
3x+4y=-4
15x+20y=-22
——————————
-5(3x+4y)=-5(-4) multiply 1st equation by -5 so you can eliminate the variables
-15x-20y=20. Modified 1st equation
15x+20y=-22. 2nd equation
0+0=-2. Added two equations together
since 0 does not equal -2, there is no solution.
I'm not sure what the 26 and 44 is there for but I'm guessing u want to multiply so in order to find the difference u got to multiply both sides the subtract so the answer would be 352
-5/2 is equivalent to -2.5, and if you multiply 2.5 by 2 you get 5, and you have to have the negative, so add that to the 5 and you get -5. Hope this helps!
1. Slope = rate of change
Shown on the graph, for 2016 there are 36 entries. For 2017, there are 40
Since it’s only one year
You can subtract 36 from 40
40 - 36 = 4
Solution: the slope is 4
2. Months increase the most, the lines which are steeper and going upward (since it’s increasing)
Solution: from 2015 to 2016
The answer to the question is a
