Answer:
yes
Yes; the graph passes the vertical line test.
Step-by-step explanation:
if it were a graph of a circle it would not pass
the vertical line test because the vertical line would touch at least 2 points
graph is probably a cubic function
something like
y = x^3-4x+6
Answer:
Step-by-step explanation:
I can't really see the graphs very well but it is either A or B.
If you want to find your answer, see which line starts at 2 on. the y line. From there using your finger go up 3 and right 1
(300 students) because each classroom has 25 students then you times that by 12 and you get 300.
Answer:
14
f(x) = 7
-7^2 + 9(7)= -49 + 63 = 14
Answer:
x = 1
Step-by-step explanation:
Well the first step is to apply the distributive property:
4(3x - 1) is equal to (12x - 4). You DISTRIBUTE a '4' to what is inside the parentheses.
And btw, to make it easier, you can make 9 - x so that x is first. For example, (-x + 9). They're both the same thing, just written differently.
Your new equation is 12x - 4 = -x + 9. You want to now solve the equation.
Add the (-x) to both sides. It cancels out on the right side and you add it to 12x on the left side.
[If there's no number in front of a variable, you can always just put 1 in order to make it easier]
12x + 1x = 13x. Your new equation is 13x - 4 = 9. This should look very familiar. You simply add 4 to both sides. 9 + 4 = 13
Finally, 13x = 13. Divide 13 ÷ 13 to get 1.
x = 1
