Answer:
Nope they are not parallel.
Step-by-step explanation:
first find the slope of each equation.
-4x+4y= -1
4y= 4x -1
y= (4x-1)/4
y=x - 1/4
the other equation
4x +4y = -1
4y= -4x -1
y= (-4x-1)/4
y= -x -1/4
the slope is the number in front of the x so for the first equation, it is 1 and the second equation it is -1. Since they are not the same, they are not parallel but instead is perpendicular. TBH, just stop here as this is more than enough.
Since we know that 1 foot is 12 inches, we can determine that a half of a foot is 6 inches. We have 7 feet, so we need to multiply 12 and 7 to find 7 feet in inches. 12*7 is 84, but we still have to add in our additional 6 inches. When we add 6 to 84, we get 90. Therefore, the classroom door is 90 inches tall.
(x^2+7x+1)/(x^2+2x-15)
A discontinuity, specifically a vertical asymptote, will occur when the denominator is equal to zero as division by zero is undefined.
(x^2+2x-15)
(x+5)(x-3)
So you will have two of them, when x=-5 and x=3

Answer:
Aisha has 6 chocolates
Step-by-step explanation:
Since Isa has 7 more than 5 times of Aisha's you first subtract 7. Once you subtract 7, you are now left with 5 times the amount (30 chocolates.) You now divide 30 by 5 and get 6 chocolates.
