Which function is a quadratic function? c(x) = 6x + 3x3 d(x) = x – 8x4 p(x) = –5x – x2 k(x) = 2x2 + 9x4
2 answers:
Answer:
p(x) = –5x – x2
Step-by-step explanation:
just took the test
Easy quadratic means 2nd degree means highest power of exponent is 2 so like x^2 first one we have 3x^3, that is 3rd degree,nope 2nd one we have 8x^4, nope, that is 4th degree 3rd one we have -x^2, yep 4th one, we have 9x^4, that is 4th degree answer is 3rd one or p(x)=-5x-x^2

So all your doing is plotting the points, for example find 0 then count forward twice- u will plot and label it their. Its the same process for each number. (ps if its negative go backwards)
Answer:
x = -5 , y = -5
Step-by-step explanation:
- 8y + 9x = -5
8y + 7x = -75
__________
0 + 16x = - 80
x = -80 / 16
x = -5
- 8y + 9x = -5
-8y + 9(-5) = -5
-8y - 45 = -5
-8y = -5 + 45
-8y = 40
y = 40/-8
y = -5
hope it helps!
I thought doubling everytime except for the number 19000 because if you do 250 × 2 = 500 so then you do 500×2=1000.

Answer:
3.75
Step-by-step explanation:
5 1/4÷1/3
so,
= 5 1/4×3/1
= 5 × 0.75
