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?

Answer:

29 words/min

Step-by-step explanation:

y = 3.8x + 17.4

y = (3.8 x 3) + 17.4

y= 11.4 + 17.4

y = 28.8 --- 29 words

Write one word problem using arithmetic sequences and another using geometric sequences.
Levart [38]
Hey There!

If i got this down right,
An = A1 + (n - 1)d
Sn = A1 + A2 + A3 + ... + An
A1 is given by
Sn = n (A1 + An) / 2
For Example

An = A1 + (n - 1)d
= 6 + 3 (n - 1)
= 3 n + 3
n = 50

Hope This Helps!!!

Goryan [66]

A tax refund is not an extra money earned by a person, it is actual an excess of what was paid by the person that the IRS have decided to give back to that person.Taxes are usually deducted based on information declared in Form W-4. The yardstick used by IRS is a straightforward method to lessen your assessable wage, yet you have the choice to ascertain your own ordered findings, utilising your genuine deductible costs.</span>

consider the following equations: -x-y=1 y=x+3 if the two equations are graphed, at what point do the lines representing the two
Oksana_A [137]

Answer:

(-2, 1)

Step-by-step explanation:

consider the following equations: -x-y=1 y=x+3

For the lines to intersect, the  values must be the same

-x-y=1

x + y = -1

y = -x - 1

Equating the y values

-x - 1 = x+ 3

-x-x = 3 + 1

-2x = 4

x = 4/-2

x = -2

Substitute x = -2 into y = x+3

y = -2 + 3

y = 1

Hence the required coordinate is (-2, 1)

How do you solve a-9/a3
Klio2033 [76]
Is it this?
\frac{a - 9}{a3}
If so, then
\frac{a - 9}{a3}  = 0 \\  \frac{a}{a3}  -  \frac{9}{a3}  = 0 \\  \frac{1}{3}   -  \frac{9}{a3}  \\  \frac{1}{3}  =  \frac{9}{a3}  \\ 3( \frac{1}{3} ) = 3( \frac{9}{a3} ) \\ 1 =  \frac{9}{a}  \\ a = 9
