Use the discriminant to find the number of real roots in Y = x^2 – 6x + 9

1 answer:

4 0

So discriminant is being counted from that equation:
b^2-4ac = 36-36 = 0

As discriminant is 0, then there is just 1 root -> -b/2a = 6/2 = 3.

There are 110 calories per 177.4 grams of Cereal X. Find how many calories are in 238.5 grams of this cereal

patriot [66]

Answer: 147.87 calories

Step-by-step explanation:

Let the amount of calories in 238.5 grams of this cereal be represented by x.

Based on the information given, we can form an equation as:

110/177.4 = x/238.5

x = (238.5 × 110) / 177.4

x = 147.87

Therefore, there are 147.87 calories in 238.5 grams of this cereal.
