A sewing machine is at a 20% off sale. The original price was $340. How much does the sewing machine cost at a 20% off sale?
Anvisha [2.4K]

Answer:

272$

Step-by-step explanation:

Since it is at a sale of 20% off that means that we will have to subtract 100% from 20% which is 80%

Now to find the exact value, we will have to multiply 80%, or 0.80 with 340

0.80*340= 272$

Therefore our answer is 272$

Which function is a quadratic function? c(x) = 6x + 3x3 d(x) = x – 8x4 p(x) = –5x – x2 k(x) = 2x2 + 9x4
Citrus2011 [14]
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
