Answer:
Step-by-step explanation:
x − 5 = 0 ⇒ x1 = 5
3x + 1 = 0 ⇒ x2 = −1
3
≈ −0.333333
Factorization:
(x − 5)(3x + 1) = 0
Standard form:
3x2 − 14x − 5 = 0
Extrema:

Answer:
Water = 1/5 of the volume of the syrup
Step-by-.step explanation:
Suppose we had 1000 cm^3 of syrup and the new volume after adding water is x cm^3. Now the amount of sugar stays the same so we have the equation 35 * 1000 = 25 * x
x = (30 * 1000) / 25 = 30,000 / 25
= 1200 cm^3
So we need to add 200 cm^2 of water .
In general terms, we need to add water which equals 1/5 of the volume of the syrup,
This is just adding them together.

Answer:
4 2/9 is less than 10 1/4
Step-by-step explanation:
Answer:
11/3
Step-by-step explanation:
x=1, R=39, y=?
R=6x + 9y
(substitute the parameters into the equation)
39=6(1) + 9y
39= 6 + 9y
(collect like terms)
39 - 6 =9y
33=9y
(divide both sides by 9)
33/9=9y/9
11/3=y
therefore, y= 11/3
