Answer:

Tara shouldn't use the fertilizer because the plant with the fertilizer had a growth rate of 3.1 millimeters per day and the plant without the fertilizer had a growth rate of 3.4 millimeters per day.

Step-by-step explanation:

This is basically a slope problem.

The equation for slope is y1-y2/x1-x2

So take two points. Time would be your X. Height would be your Y.

I chose

6 - 18.6

8 - 24.8

So: 24.8-18.6/8-6 = 3.1 The slope of the growth of the plant is 3.1 mm per day.

Two cars got an oil change at the same auto shop. The shop charges customers for each quart of oil plus a flat fee for labor. Th

Answer:

The labor fee is $14.25, each quart of oil costs $2.25.

Step-by-step explanation:

Let $x be thee price of each quart of oil and $y be a flat fee for labor.

1. If the oil change for one car required 5 quarts of oil, then these 5 quarts cost $5x and together with a flat fee for labor it cost $25.50. Thus,

5x+y=25.50.

2. If the oil change for another car required 7 quarts of oil, then these 7 quarts cost $7x and together with a flat fee for labor it cost $30.00. Thus,

7x+y=30.00.

3. Subtract from the second equation the first one, then

$7x+y-(5x+y)=30.00-25.50,\\ \\7x+y-5x-y=4.50,\\ \\2x=4.50,\\ \\x=\$2.25.$

Substitute it into the first equation:

$5\cdot 2.25+y=25.50,\\ \\y=25.50-11.25,\\ \\y=\$14.25.$

The labor fee is $14.25, each quart of oil costs $2.25.

Paraphrase the following steps:

•Draw a line connecting the point to the center of the circle
•Construct the perpendicular bisector of that line
•Place the compass on the midpoint, adjust its length to reach the end point, and draw an arc across the circle
•Where the arc crosses the circle will be the tangent points.
