Answer:

An equation of the line that passes through the point(2,−5) and is parallel to the line 6x+y=6 is:

$y=-6x+7$

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where m is the slope and b is the y-intercept

Given the equation

$6x+y=6$

Writing in the slope-intercept form of the line equation

$y = -6x + 6$

comparing with the slope-intercept form of the line equation

y = mx+b

Thus, the slope of line = m = -6

We know that the parallel lines have the same slopes.

Thus, the slope of the parallel line is also -6.

As the line passes through the point (2,−5).

Thus, using the point-slope form of the line equation

$y-y_1=m\left(x-x_1\right)$

where m is the slope and (x₁, x₂) is the point

substituting the values m = -6 and the point (2,−5)

$y-y_1=m\left(x-x_1\right)$

$y - (-5) = -6 (x - 2)$

$y+5=-6\left(x-2\right)$

subtract 5 from both sides

$y+5-5=-6\left(x-2\right)-5$

$y=-6x+7$

Therefore, an equation of the line that passes through the point(2,−5) and is parallel to the line 6x+y=6 is:

$y=-6x+7$

How many 4' x 8' sheets of plywood are required to cover a floor that is 9 m by 16 m?

Xelga [282]

Assuming no border or waste, 9m by 16 m translates to 29.52' x 52.49'.
use 32/8=4 sheets of plywood to cover the width on the 8' side.
For the length, use 52/4=13 pieces on the 4' side.
This gives a total of 4*13=52 sheets.
The extra 0.49' x 29.52 can be covered using the extra from the last four sheets for the width.

Check:
Area to be covered: 29.52*52.49=1550 sq. ft.
Area of plywood supplied = 52*4'x8'= 1664 sq. ft, > 1550 sq.ft.

A cab company charges according to the following rate chart. Which graph correctly represents the charge, y, in dollars for a ca

77julia77 [94]

The graph is the one that correctly represents the linear piece-wise function is the first graph.

<h3>How to solve for the graph</h3>

First we have a linear function as

Mx + b

mc= slope, this is the rate of change, how y changes as x changes by 1.

b = y-intercept, y value as x = 0

y = 5 + x

x ≤ 10

at 10 we have 5 + 10 = 15

at 2 dollars

y = 15 + 2(x - 10)

at 14

y = 15 + 2(14 - 10)

15 + 2*4

= 23

Hence we can conclude that the first graph here is the correct one.
