Answer:
B
Step-by-step explanation:
You should find the solution for this system of equations (The value of x is the first coordinate for the point of intersection, the value of y is the second coordinate for the point of intersection)
X+y=0.3
y=3x+16.7
use 3x+16.7 instead of y in the first equation(do it to get only x in the first equation)
x+3x+16.7=0.3
4x+16.4=0
4x=-16.4
x=-4.1
y=0.3+4.1=4.4

Step-by-step explanation:
This problem is very similar to one I solved a few moments ago. First we need to know how much it rain during the month of august the first 15 days of august. We only know how much it rain from the 15th through the end of the month.
So if you want to know the total rainfall of the month, you only need to sum the amount of the rainfall from the first 15 days of august and the last days of the month.
To help you out, I will use the same data of the other problem, which was 8.33 cm for the first 15 days, and 4.65 for the last 15 days of august.
If you sum 8.33 and 4.65:
8.33 + 4.65 = 12.98 cm
This would be (theorically speaking) the total rainfall during this month. Now, if it's the same exercise that you have, then good, use this answer, but if it's not then, all you need to do is put the value for the first 15 days and do the sum with 4.65 cm to get the total.
Answer:
Step-by-step explanation:
To be a function x can't repeat with a different y so in a every element of x is mapped to a different y so it is a function.
For choice B, -4 is paired with both 7 and 8 so it is not a function.
Choice C is a function since each x is paired with a different y.
The answer is -5, -5 added by 5 cancels each other out. Then when you add 4x + 8x, you get 12x. So when you do 12x= -60, you get -5.
