"Linear function" means the highest degree of any term is 1.
Equation 1: degree is 2
Equation 2: degree is 2
Equation 3: degree is 1 . . . . this is your linear function
Equation 4: degree is 4
Hey there! :) The answer to your question is $12 per pound. To find a unit rate you divide $60/5= $12. To double-check, 1 pound is $12, 2 pounds is $24, 3 pounds is $36, 4 pounds is $48, and lastly 5 pounds is $60. I hope you have a great day, and keep smiling! :D Also hoped I helped! ;)
- 18
2- 20
= -18
Because you do the same thing just going to end up with a negative.
Work backwards from vertex form. Vertex form of a quadratic equation/parabola is the following:
f(x) = a(x - h)² + k, where (h, k) is the vertex.
f(x) = a(x - 6)² - 9
Now, plug in the point that you're given to SOLVE FOR A. Remember that f(x) is just another way of writing y.
8 = a(1)² - 9
8 = a - 9
a = 17
So, plug in a = 17 into the equation.
<span>f(x) = 17(x - 6)² - 9 ←← your answer.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.
