Quadratic means 2nd degree

means highest power of variable is 2


c(x)=6x+3x^3
3rd degree, not quadratic

d(x)=x-8x^4,
4th degree, not quadratic

p(x)=-5x-x^2
2nd degree, it's quadratic

k(x)=2x^2+9x^4
4th degree, not quadratic

answer is p(x)=-5x-x^2

After eating a meal at a restaurant, we decided to tip 25%, building a grand total of $87.50. What was the price before the tip?
CaHeK987 [17]

Answer:

65.62

Step-by-step explanation:

Given:

After eating a meal at a restaurant, we decided to tip 25%, building a grand total of $87.50.

To find:

Price before tip

Solution:

87.50 × 25% = 21.875

~Round~: 21.875 to 21.88

87.50 - 21 .88 = 65.62

Thus the price before the tip is 65.62

Check Answer:

<em>Formula: Higher number - Lower number ÷ original number × 100</em>

<em>Solve: </em>

<em>87.50 - 65.62 = 21.88</em>

<em>21.88 ÷ 87.50=0.25005714285</em>

<em>0.25005714285 × 100 = 25.0057142857</em>

<em>Round - 25%</em>

belka [17]

Answer:

A(2,1) , B(-3,2) , C(-1,6)

Step-by-step explanation:

A translation of 2 units up means the y values will be shifted up 2 units

A (2,-1) -> A(2,1)

B (-3,0) -> B(-3,2)

C (-1,4) -> C(-1,6)
