Answer:
Neither
Step-by-step explanation:
2y = 16x + 42
y = 8x + 21
Slope=8
6y - 30 = 12x
6y = 12x + 30
y = 2x + 5
Slope=2
Answer:
no
Step-by-step explanation:
If you mean
27^4 - 9^5·3^9 = -1161730026
it has no factors of 5, so cannot be divisible by 25.
__
If you mean ...
(27^4 -9^5)/3^9 = ((3^3)^4 -(3^2)^5)/3^9 = 3^10(3^2 -1)/3^9 = 3(9-1) = 24
it is not divisible by 25, either.
Answer:
They want you to write 1/100 using a negative exponent other than -1. 10 is the square root of 100, because 10 x 10 is 100. A negative number times a negative number is a positive number. So, 10^-2 is the same as -10 x -10, which is equal to 100.
10^-2
= -10 x -10
= 100
Answer:
A. Parallel
Step-by-step explanation:
Parallel lines are two lines that never intersect and will never intersect. In equations, this will mean the slopes will be the same while the y-intersect is different. They are not perpendicular because perpendicular lines will intersect at a right angle, and these lines never intersect.
