You can use the slope formula or just calculate
So for the first problem you run 3 units right and rise 5 units so
2. Notice the y axis goes by 2 units.

Please let me know if you have questions
The unknown variables are how many tickets are being bought and the total.
t=tickets
x=total
44t+12=x
Answer:
(-1, 6)
Step-by-step explanation:
A graphing calculator shows the vertex to be (x, y) = (-1, 6).
__
You can also find it by putting the equation into vertex form.
y = -2(x^2 +2x) +4
y = -2(x^2 +2x +1) +4 +2(1) . . . . . add 1 inside parens; the opposite outside
y = -2(x +1)^2 +6
Compare to ...
y = a(x -h)^2 +k
and you see a=-2, h=-1, k=6
The vertex is (h, k) = (-1, 6).
Answer:
Step-by-step explanation:
<em>Note all arguments of trigonometric functions are in degrees.</em>
<em />
Since tan(35)=4/(longer dotted leg of the triangle), the length of this longer dotted leg is thus 4/tan(35).
Since A=bh, the area is (4/tan35)(12), and you can just plug this into a calculator.
