Given the domain {-2, 1, 5}, what is the range for the relation 4x + y = 3?

steposvetlana [31]

Answer:

Step-by-step explanation:

Domain is the set of all possible inputs (x) for the function f(x)

The range is the set of all possible values for that domain

This function is 4x + y = 3 which can be re-written as y = 3-4x

Plug in each of the domain values and you will get the range

For -2 : y = 3-4(-2) = 3 + 8 = 11

For 1: y = 3-4(1) = -1

For 5: y = 3-4(5) = -17

So range is {-17, -1, 11}

What is the value of x in the inequality start fraction seven minus two x over negative four end fraction plus two less than neg

algol13

Answer:

$x$

Step-by-step explanation:

$\frac{7-2x}{-4} +2$

Subtract 2 from both sides

$\frac{7-2x}{-4}$

mutliply both sides by -4, flip the inequality

$7-2x >4x+8$

Add 2x on both sideds

$7>6x+8$

Subtract 8 from both sides

$-1>6x$

Divide both sides by 6

$x$

CAN SOMEONE HELP ME !!!!!!!!!

MissTica

Answer:

She will get 80mg of dextromethorphan and 800mg of guaifenesin. And the bottle last for 6 days approximately.

Step-by-step explanation:

Given that the Robitussin DM contains dextromethorphan 10mg/5mL and gualfenesin 100mg/5mL. And we are also given that Mrs Smith took four doses and each dose is 2 teaspoons=2X5=10mL.

So, four doses=4X10=40mL.

So, dextromethorphan in 4 doses is = $\frac{10}{5}X40=80mg$

And Guaifenesin in 4 doses is = $\frac{100}{5}X40=800mg$

Dosage of medicine daily she has to take=40mL and the bottle contains 237 mL. Hence the number of days bottle last = $\frac{237}{40}=5.925$ ≈6 days approximately.
