5 0

The ordered pairs  that make this equation true is (4, 10)

A linear equation is given by:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept.

Given the linear equation: y = 10x - 30:

At (1, -12): y = 10(1) - 30 = -20 ≠ -12

At (8, 1): y = 10(8) - 30 = 50 ≠ 1

At (4, 10): y = 10(4) - 30 = 10

At (6, 20): y = 10(6) - 30 = 30 ≠ 20

The ordered pairs  that make this equation true is (4, 10)

Themba has 6.75 cups of yoguri and needs to make 5 bowls of fruit dip. Each bowl
rodikova [14]

With 6.75 cups of yogurt , we can make 4 bowls of fruit dip.

<u>Step-by-step explanation:</u>

We have ,Themba has 6.75 cups of yoguri and needs to make 5 bowls of fruit dip. Each bowl  uses 1.5 cups of yogurt  .

<u>With 1.5 cups of yogurt:</u>

With help of 1.5 cups of yogurt one bowl of fruit dip is made. Now we are left with (6.75 - 1.5 = 5.25) cups of yogurt. Number of bowls of fruit dip = 1.

<u>With another 1.5 cups of yogurt:</u>

With help of 1.5 cups of yogurt one bowl of fruit dip is made. Now we are left with (5.25 - 1.5 = 3.75) cups of yogurt. Number of bowls of fruit dip = 2.

<u>With another 1.5 cups of yogurt:</u>

With help of 1.5 cups of yogurt one bowl of fruit dip is made. Now we are left with (3.75 - 1.5 = 2.25) cups of yogurt. Number of bowls of fruit dip = 3.

<u>With another 1.5 cups of yogurt:</u>

With help of 1.5 cups of yogurt one bowl of fruit dip is made. Now we are left with (2.25 - 1.5 = 0.75) cups of yogurt. Number of bowls of fruit dip = 4.

Now, Another bowl of fruit dip couldn't be made because we have only 0.75 cups of yogurt ! So, with 6.75 cups of yogurt , we can make 4 bowls of fruit dip.

Identify the equation of the line perpendicular to 9x - 3y = 18.
sweet [91]

Answer:

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes.

The exemplar equation has slope

9x - 3y = 18

    - 3y = -9x + 18

        y = 3x - 6

m = 3

so perpendicular slope will be -1/3

D has such a slope

3y = -x + 1

 y = (-1/3)x + 1/3
