How to solve this step by step n get the answer

lana66690 [7]

Answer:

Answer 1 :-

$\implies m_1 = -3$

$\implies y - intercept = 7$

Answer 2 :-

$\implies m_1 = -\dfrac{1}{2}$

$\implies y - intercept = -4$

Step-by-step explanation:

The Slope Intercept Form of the line is given to us . The equations given are ,

$\implies y + 3x = 7$

$\implies y + \dfrac{1}{2}x = -4$

Now we know the standard equation of slope intercept form , is

$\implies y = mx + x$

Where ,

m is slope
c is y intercept .

So , we can write about the equations as ,

$\implies y = -3x + 7$

$\implies y = - \dfrac{1}{2}x -4$

On comparing to the Standard form ,

Answer 1 :-

$\implies m_1 = -3$

$\implies y - intercept = 7$

Answer 2 :-

$\implies m_1 = -\dfrac{1}{2}$

$\implies y - intercept = -4$

Round 6.75 to the nearest hour

Ronch [10]

Answer:

6.75 hour is approximated to 7 hours

Step-by-step explanation:

Given

Time = 6.75 hours

Required

Round to the nearest hour

The time given is given in base 10 and the conversion can be done in two ways.

1. Convert directly by approximation.

Approximating 6.75 to the nearest whole number gives 7.

Hence, 6.75 hours = 7 hours

2. Convert to time equivalent then approximate time

This is done as follows

$6.75 hours = 6 hours + 0.75 hour$

Convert decimal to fraction

$6.75 hours = 6 hours + \frac{75}{100} hour$

Simplify to lowest term

$6.75 hours = 6 hours + \frac{3}{4} hour$

Convert hour to minute

There are 60 minutes in an hour

$6.75 hours = 6 hours + \frac{3}{4} * 60 minutes$

$6.75 hours = 6 hours + 3 * 15 minutes$

$6.75 hours = 6 hours + 45 minutes$

The rule of time approximation is that; if the minutes is between 0 and 29, it'll be rounded to 0; else, it'll be rounded up to 1

Going by the rule, 45 minutes will be approximated to 1 hour.

This gives

$6.75 hours \frac{=}{} 6 hours + 1 hour$

$6.75 hour \frac{=}{} 7 hours$

Hence, 6.75 hour is approximated to 7 hours
