To find a linear question, we must have two points on the line and we must know the slope.

Let us choose two points at random:

    (-6,12)    and    (-5,14)

Now let us find the slope of the linear line:

 m = \frac{y2-y1}{x2-x1} =\frac{14-12}{-5--6}  = 2

   So the slope is 2.

Now let us set up the equation which now requires only one point and the slope

      let us use the point (-6,12) and the slope of 2

      y-12 = 2(x+6)\\y = 2x +12 +12\\y= 2x +4

So the linear line is y = 2x + 4.

Hope that helps!

In a recipe for fizzy grape juice, the ratio of cups of sparkling water to cups of grape juice concentrate is 3 to 1. a) Find tw
Verizon [17]

Answer:

6:2,\,9:3

Step-by-step explanation:

Given: The ratio of cups of sparkling water to cups of grape juice concentrate is 3:1 in a recipe for fizzy grape juice.

To find: two more ratios of cups of sparkling water to cups of juice concentrate that would make a mixture that tastes the same as this recipe

Solution:

Equivalent ratios are the ratios that have the same value.

Find two ratios equivalent to 3:1=\frac{3}{1}

Multiply both numerator and denominator of \frac{3}{1} by 2

\frac{3(2)}{1(2)} =\frac{6}{2}

Multiply both numerator and denominator of \frac{3}{1} by 3

\frac{3(3)}{1(3)} =\frac{9}{3}

So, two more ratios of cups of sparkling water to cups of juice concentrate that would make a mixture that tastes the same as this recipe are 6:2,\,9:3

Harold earns $10.50 per hour working at a doctor's office. On Monday he spent 1 5/12 hours filing paperwork, 1 3/4 sending email
Lana71 [14]

Answer:

the total earnings is $58

Step-by-step explanation:

The computation of earnings is shown below:

= Time spent in filling paperwork + time spent in sending emails + time spent in making appointments

= (1 5 ÷ 12 × $10.50)  + (1 3 ÷ 4 × $10.50)  + (2 1 ÷ 3 × $10.50)

= 14.875 + 18.375 + 24.50

= $57.75

Hence, the total earnings is $58

The same is to be considered
