Rearrange the equation so r is the independent variable.<br><br> 10q - 5r = 30
Murljashka [212]

Answer:

q = 3 + 1/2r

Step-by-step explanation:

10q - 5r = 30

We want to solve for q

Add 5r to each side

10q - 5r+5r = 30+5r

10q = 30+5r

Divide by 10

10q/10 = 30/10 +5r/10

q = 3 + 1/2r

Show your work AND the answer a research showed that 45% of sixth graders have dogs for pets 35% have cats 10% have fish and 5%
Arturiano [62]

Answer: 600 students

Step-by-step explanation:

Of the total number of sixth graders who were surveyed, 5% owned birds.

This 5% translated to 30 students.

30 students is therefore 5% of the total number of sixth graders surveyed.

Assume that number to be x:

x * 5% = 30

x = 30 / 5%

= 600 students

A 1200 gram sample of radioactive matter will completely decay (be undetectable) in 10 hours. There exists a set of ordered pair
julia-pushkina [17]

Using it's concept, the range of the function is given as follows:

0 ≤ m ≤ 1200.

<h3>What is the range of a function?</h3>

The range of a function is the set that contains all possible output values for the function.

For this problem, we have to consider these two bullet points next, considering the mass is the output value of the function.

  • The smallest possible mass for the substance is of 0 grams, as after the substance decays to 0 grams, it will not assume a negative value, it will just disappear.
  • The greatest possible mass for the substance is the initial mass of 1200 grams, as the substance does not adquire mass with time, it just loses it.

Considering these masses, the range of the function is given as follows:

0 ≤ m ≤ 1200.

A marketing company is designing a new package for a box of cereal. They have determined that the function C(x) = 4.5 x2 models
Vlad1618 [11]

So the function is

\\ \rm\rightarrowtail y=4.5x^2

As we know

  • x²≥0
  • x≥0

hence domain is

\\ \rm\rightarrowtail D_f\in R

  • Least value of function is at x²=0 i.e 0

Hence range:-

\\ \rm\rightarrowtail R_f\in [0,\infty)
