Answer:
Step-by-step explanation:
We are given that a line y=-3 .
We have to find the line which is perpendicular to given line and passing through the point (6,2).
Given line y=-3
It is a horizontal line .
The line which is perpendicular to horizontal line is a vertical line .
The equation of vertical line is x=a
We are given that perpendicular line passing through the point (6,2).
It means the vertical line is x=6.
Therefore, the equation of perpendicular line which is passing through the point (6,2) and perpendicular to given line is given by
Answer:
The answer is 5
Step-by-step explanation:
Rationalizing the denominator of the expression, it is found that the simplified expression is given by:
<h3>What is the expression that we have to simplify?</h3>
It is given by:
We rationalize the denominator, using the subtraction of perfect squares, hence:
Then, solving the expression:

Answer:
Step-by-step explanation:
The hardware store has 200 paintbrushes. They order 9 boxes with 12 paintbrushes each. This means that the total number of paintbrushes that was ordered is
12 × 9 = 108
Therefore, the total number of paintbrushes that the store has would be
200 + 108 = 308
They sell 11 boxes that have 6 paintbrushes each. This means that the total number of paintbrushes that they sold is
11 × 6 = 66
Therefore, the number of paintbrushes left would be
308 - 66 = 242
The manager's estimate is reasonable. They ordered about 120 paintbrushes and sold about 60 of them so they should have about 60 more paintbrushes than they started with.
