Answer:
a
Step-by-step explanation:
(y-y1) = m(x-x1)
y-2 = 5(x-6)
Therefore, point (x1,y1) lies on the line of equation
Therefore, point (6,2) lies on the line with the point slope equation y-2=5(x-6)
Answer: a plumber earns $50 each day and a helper earns $30 each day.
Step-by-step explanation:
Let x represent the amount that a plumber earns in a day.
Let y represent the amount that a helper earns in a day.
One day, four plumbers and five helpers earned $350. This means that
4x + 5y = 350 - - - - - - - - - - -1
At the same rate of pay, another group of five plumbers and six helpers earned $430. This means that
5x + 6y = 430 - - - - - - - - - - - - 2
Multiplying equation 1 by 5 and equation 2 by 4, it becomes
20x + 25y = 1750
20x + 24y = 1720
Subtracting, it becomes
y = 30
Substituting y = 30 into equation 1, it becomes
4x + 5 × 30 = 350
4x + 150 = 350
4x = 350 - 150
4x = 200
x = 200/4 = 50
we know that
A difference of squares problem can be factored as follows:
in this problem we have
Applying difference of squares
the term
substitute
therefore
<u>the answer is</u>
So what we do is we splie it up
remember that 1/1=1 so therefor 6/6=1
find out how many 6/6 are in 23 and how much is left over
remember that you can add the top numbers if the bottom numbers are the same
23/6-6/6=17/6 (that's one)
17/6-6/6=11/6 (that's 2)
11/6-6/6=5/6 (that's three)
therefor you have
23/6=6/6+6/6+6/6+5/6=1+1+1+5/6=3+5/6=3 and 5/6
therfor 3 goes in the blank in front of the 5/6
