3,500km way bigger than the rest of the other answers
Answer:
x=63; y=27
Step-by-step explanation:
The straight line of the 117 is 180 and so you subtract 180 to 117 to get 63 which is x and then subtract 90 and 63 to get 27.
D because of the vertical line test. The c input 2 has two different out puts meaning that it is not a function
Answer:
C
Step-by-step explanation:
So the system is:
5x+13y=232
12x+7y=218
------------------
Let's look at the options to see which will work:
A) Multiply first equation by -13: -65x-169y=-3016
& second equation by 7 : 84x+49y=1526
There are no opposites in the either one of the variable columns so not this option.
B) Multiply first equation by 7: 35x+91y=1624
& second equation by 13 : 156x+91y=2834
There are no opposites in the either one of the variable columns so this is not option unless we were asked to subtract the equations.
C) Multiply first equation by -12: -60x-156y=-2784
& second equation by 5 : 60x+35y=1090
There is a column that contains opposites here so when you add the equations the x-variable will get eliminated.
It’s c because of the distribution
