(7+4=11 white and red marbles) / (2+1+7+4=14 marbles in total) = 11/14
Answer:
Option 3
Step-by-step explanation:
-2/3 since the line is a total of 3 the 2 is negative which would make it the answer meaning that is the only negative option.
Yes you are correct! This equation will make a parabola. The width when the arch is at ground level would be the x-intercepts, or zeros, of the parabola.
The vertex point is (0,12)
the axis of symmetry is 0
The zeros are (-4,0) and (4,0)
using the zeros take away the negative because something cant be negative feet wide and add the numbers together (4+4)
Your answer is 8

Hope this helps you!
P.S. Can i get brainliest? :)
You have a lot of questions here, I can help with some.
1) To find the inverse, switch the x and f(x) and solve for f(x).
x = 3f(x) - 7
x + 7 = 3(f(x)
(x + 7) / 3 = f(x)
2) It is a function, because each input pairs with only 1 output.
3) Any diagonal line would be a function.
4 - 8 (We can't do without the diagram)
9) f(-9) = 3(-9) - 6
f(-9) = -27 - 6
f(-9) = -33
10) f(-2) = 42 + 3
f(-2) = 45
Answer:
False
Step-by-step explanation:
If make 2 1/8 into an improper fraction, it will be 17/8. a reciprocal is a flip of a number, so it is false.
