Answer:
B: (-1,2)
Step-by-step explanation:
I think it is answer B because
and (-1,2) is the closest to the origin(0,0) and to 2.2361.
F(-2) is when x = -2
On the graph it’s (-2, 2)
Solution: f(-2) = 2
35-15 is 20. and 43-26 is 17. These two are different because you are regrouping in the 2d problem, as in the first, you just subtract.
They are both equal to y so you can set them equal to each other to solve for x:
14x - 6 = -4x + 48
18x = 54
x = 3
To solve for y just plug 3 into the x of one of the given equations
y = 14(3) - 6
y = 42 - 6
y = 36
To check:
36 = 14(3) - 6
36 = 42 - 6
36 = 36
36 = -4(3) + 48
36 = -12 + 48
36 = 36
Hope this helped!
Answer: 5/16 (the first one)
s/80 the second one
Step-by-step explanation: it says the ratio for 7th grade simmers to all swimmers is 5:16 so that’s ur first box and it said there are 80 total swimmers so, 80 goes in the other one
