Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 2, 9 ) and (x₂, y₂ ) = (- 2, - 5 )
m = 
= 
= 
Since division by zero is undefined then the slope is undefined
ThE answer is C, congrats
The total number of pieces of chalk in the classroom will be the number of pieces in the 4 boxes in addition to the six individual pieces.
The average box of chalk holds 12 pieces of chalk
This means that 4 boxes have 12*4 = 48 pieces
Total number of pieces = 48 + 6 = 54 pieces of chalk
It's 3/4 because the only factor you can divide them both with is 2 and 3 and 4 have noi factors to divide by to make it lower.
Answer:
7/20
Step-by-step explanation:
You have: 3/5 - 1/4
When you have different denominator:
1) Multiply in cross. The numerator of the first fraction is multiplied by the denominator of the second, and the denominator of the first by the numerator of the second. Both multiplications are subtracted.
3/5 - 1/4 = [(3*4) - (5*1 )] / ...
2) The denominators of the two fractions are multiplied.
3/5 - 1/4 = [(3*4) - (5*1 )]/(5*4
)
3) Resolve operations
= (12-5)/20
= 7/20
