Answer:
Given below
Step-by-step explanation:
y = 4 , m = -1 , x = 2
y = mx + b
4 = -1 (2) + b
4 = -2 + b
6 = b
The correct option is D (-∞,-3)∪(-1,1)
Step-by-step explanation:
Given,
≤ 0
To find the solution.
The solution could be found if
≤ 0 and
3x+9 ≠ 0 [if the denominator is 0, it gives ∞ as solution]
Now,
≤ 0
or, (x+1)(x-1) ≤0
or, x ≤1 and x≤-1
Both of the above condition holds is x≤1
Again,
3x+9≠0
or, x≠-3
All the conditions gold for the values (-∞,-3)∪(-1,1)
Hence the correct option is D.

Answer:
n is 7
Step-by-step explanation:
Y=5x
the total income (y) equals $5 times how every many calenders they sell (x) because the calenders are $5 a piece
therefore the equation is y=5x
hope this helps!!
