29 mint plants and 29 other herb plants at the garden center. Considering this data, how many of the next 62 herb plants stocked

spin [16.1K]

Answer: 31 mint plants

Step-by-step explanation:

We will have mint plants over total plants:

29/29+29 = 29/58 = 1/2

Now, we will multiply 62 by 1/2 to guess how many mint plants will be stocked.

62* 1/2 = 31

We should expect about 31 plants of the total plants to be mint plants.

Write an equation of the line that passes through (18, 2) and is parallel to the line 3y−x=−12

rodikova [14]

First isolate the "y" in the equation.

2y - x = -12 Add x on both sides

2y - x + x = -12 + x

2y = -12 + x Divide 2 on both sides to get "y" by itself

$y = \frac{-12 +x}{2}$

$y = -6 + \frac{x}{2}$

Your slope is $\frac{1}{2}$ .

For the equation of the line to be parallel to the given equation, the slopes have to be the same. So the parallel line's slope is also $\frac{1}{2}$

y = mx + b

$y = \frac{1}{2}x + b$

To find "b", you plug in the point (18,2) into the equation

$y = \frac{1}{2}x + b$

$2 = \frac{1}{2}(18) + b$

2 = 9 + b Subtract 9 on both sides

2 - 9 = 9 - 9 + b

-7 = b

Your equation is:

$y =\frac{1}{2}x - 7$
