For several years, Graham has gathered data on students who own a computer and on their performance on a typing-speed test. He c

reates the linear model y = 3.8x + 17.4 where y represents the typing speed, in words per minute, of a student and x represents the number of years the student has owned a computer. According to Graham’s model, what is the approximate speed of a student who has owned a computer for three years?

Y = 3.8x + 17.4
y = (3.8 x 3) + 17.4
y= 11.4 + 17.4
y = 28.8

What is the domain of the function f(x)=<img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D" id="TexFormula1" title="\sqrt{x}" alt=
katrin2010 [14]

Step-by-step explanation:

The domain of f(x) is all values of x for which f(x) is defined.

For f(x) to be defined, the expression under the radical must be non-negative.

Therefore, the domain is x ≥ 0, or in interval notation, [0, ∞).

You buy x bottles of soda for $1.50 using a gift card that you got as a reward for getting good grades
nadya68 [22]

Answer:

0\leq x \leq 10

Step-by-step explanation:

The function is  f(x)=15-1.50x  where x is the number of bottles of soda.

The domain means the set of "allowed" x values.

Also, f(x) means the amount of money left, which cannot be less than 0. So we put 0 into f(x) and solve for x:

f(x)=15-1.5x\\0=15-1.5x\\1.5x=15\\x=\frac{15}{1.50}\\x=10

This means the highest number of bottles you can buy is 10. So the domain is anything from 0 to 10. <em>You can buy 0 until highest 10 bottles. Hence the domain is </em>

0\leq x \leq 10
