The answer is B because the x describes the domain and it can also be the input value
Perpendicular lines have slopes that are negative reciprocals. example: line a has a slope of 2/3, line b has a slope if -3/2 if they are perpendicular.
36:21 in simplest form is 12:7, because 3 goes into both 36 and 21. Simplifying ratios is essentially the same thing as simplifying fractions. Once we have 12:7, we can't reduce any further, because 7 is prime.
Hope this helps!
Answer:
85 parking spaces
Step-by-step explanation:
Given that :
Parking spaces on floors :
Let first floor = x
Second floor = 2x
Third floor = 2x + 3
Total parking spaces = 428
THEREFORE ;
x + 2x + 2x + 3 = 428
5x + 3 = 428
5x = 428 - 3
5x = 425
x = 425 / 5
x = 85
Hence, there are 85 parking spaces on the first floor
Answer:
1) incorrect
2) incorrect
Step-by-step explanation:
-2x-2x = 0 ?
-2x -2x = -4x
It will be 0 only if x = 0.
Not always true, so incorrect
x+x = x² ?
2x = x²
They will be equal if x = 0 or 2.
Not always true so incorrect
