Help needed (a) Use the fundamental theorem of algebra to determine the number of roots for
2x^2 + 4x + 7.
(b) What are the roots of 2x^2 + 4x + 7?

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

answer: 12   they all have at least 28 days

step-by-step explanation: haha

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get

what do you mean by "representation"? graph? table? etc.
