Answer:
Step-by-step explanation:
Let burger = b and fries = f
<u>Alica:</u>
<u>Jack:</u>
<u>Simplify the second equation and subtract from the first one:</u>
- 2b + f = 14.78
- 2b + 3f - 2b - f = 21.18 - 14.78
- 2f = 6.4
- f = 3.2
<u>Find the value of b:</u>
- 2b + 3.2 = 14.78
- 2b = 11.58
- b = 11.58/2
- b = 5.79
Your answer should be 3)-3
Answer:
p^2 + q^2 = 22/9.
Step-by-step explanation:
For a quadratic function ax^2 + bx + c if the zeroes are A and B then
A + B = -b/a and AB = c/a.
2x^2 - 7x + 3
Now p and q are the zeroes of the above function so
p + q = 7/3 and pq = 3/2.
Now p^2 + q^2 = (p + q)^2 - 2pq
= (7/3)^2 - 2* 3/2
= 49/9 - 3
= 49/4 - 27/9
= 22/9.
The answer is /6 radians. I looked up the unit circle hope this helps :)
|1/5x|
1/5 stretches the function
5 would compress the function
