Joyce spent approximately 232323 hours on video games.
A graph plots Hours spent on homework, from 0 to 24, in increments of 2, versus Hours spent on video games, from 0 to 14, in increments of 2. Dozens of points fall diagonally in a relatively tight, narrow cluster between (0.5, 23.8) and (14.1, 3.1). A regression line falls diagonally through the center of the cluster from (0, 23) to (15, 3). All values estimated.

Write an equation of the line that passes through (5, −1) and is perpendicular to the line y=12x−1.
Lisa [10]

Step-by-step explanation:

solution

let,A(5,-1)

given

y=12x-1

or, y = 12 × x + (-1)

comparing it with y=mx+c

we get

x=1

y = c = -1

now

A(5,-1) and B(1,-1)

equation of line is,

(y-y1)/(x-x1) = (y2-y1)/(x2-x1)

or, (y+1)/(x-5) = (-1+1)/(1-5)

or, (y+1)/(x-5) = 0/-4

cross multiply

-4y-4 = 0

or, 0=4y+4

or, 4y+4=0 is the required eqn

I think this is the process and answer too.

I hope this helps you

Leslie mows lawns to earn money. For each customer, she charges $2.00 for gas and $3.00 per 12 hour of work. Let x represent the
RUDIKE [14]

Answer:

See Explanation

Step-by-step explanation:

Given

Gas = \$2.00

Rate = \$3.00/12hr

\begin{array}{ccc}{Row} & {Hours} & {Earnings} & {A} & {2} & { } & {B} & {4} & { } & {C} & {6} &{ } \ \end{array} ---- Missing table

Required

Complete the table and plot the graph

First, we determine the equation of the table:

Gas = \$2.00

Rate = \$3.00/12hr implies that:

Rate = \$0.25/hr

So:

y = Gas + Rate * x

y = 2+ 0.25* x

y = 2+ 0.25 x

To complete the table, we have:

x = 2

y = 2+ 0.25 x = 2+0.25 * 2 = 2.5

x = 4

y = 2+ 0.25 x = 2+0.25 * 4 = 3

x = 6

y = 2+ 0.25 x = 2+0.25 * 6 = 3.5

So, the complete table is:

\begin{array}{ccc}{Row} & {Hours} & {Earnings} & {A} & {2} & {2.5} & {B} & {4} & {3} & {C} & {6} &{3.5} \ \end{array}

Please help! <br> i have no clue what to do!!
Oksi-84 [34.3K]

If you look up “Four 4s Challenge” on yt you should find a couple videos explaining it! i just watched a little bit of one so i’ll try and help now though.

I’ll do 1-5 for you and try my best to explain :)) and if you need more answers or more help just let me know

So first, we need to find out how to get 1 using four 4s

1. (4/4)/(4/4)

this would read “four divided by four divided by four divided by four” which equals 1

2. 4/4+4/4

3. (4+4+4)/4

4. 4*(4-4)+4

5. (4*4+4)/4

Remember that you’ve gotta use an equation with just four 4s to get to every number
