Answer:

2,5

Step-by-step explanation:

2,5 is just one of the many solutions to this problem. you can just take a random number for x, for example 2. your equation will look like this 3(2)-y=1. now you just solve for y. 3x2=6. 6-1=5. so y=5.

On average, I sleep about 7 hours and 45 minutes each day. So during one year, I sleep for 7.45x365=2719.25 or about 2700 hours.

Answer:

About 2,800 hours of sleep per year

Step-by-step explanation:

Sleep per day= 7 hours 45 minutes

7 hours 45 minutes=465 minutes

Sleep per day =465 minutes

Sleep per year=365 days × 465 minutes

=169,725 minutes

There are 60 minutes in one hour

Divide 169,725 by 60 minutes

We have,

169,725/60

=2828.7500000 hours

Total sleep in a year is about 2,800 hours

if (1,4) and (10,-68) are two anchor points on the trend line, then find the equation of the line y=[?]x + [ ]

svlad2 [7]

Answer:

y = - 8x + 12

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, 4) and (x₂, y₂ ) = (10, - 68)

m = $\frac{-68-4}{10-1}$ = $\frac{-72}{9}$ = - 8, thus

y = - 8x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (1, 4), then

4 = - 8 + c ⇒ c = 4 + 8 = 12

y = - 8x + 12 ← equation of line
