Hello,
y=3x+b is parallele to y=3x-10
In order to determine b, we must know something else.
Answer:
3n + 2
Step-by-step explanation:
-n + 4n -4 + 6
3n + 2
Answer: 1.3125 gallons
Step-by-step explanation: The machine pumps 2.1 gallons of water every 1.6 minutes. 1.6 minutes is 1.6x more than 1 minute. So, we have to divide 1.6 by 1.6. Next, we have to divide 2.1 by 1.6. We can make this a bit easier by multiplying both of them by 10 to get 21/16 which is 1.3125.
If you're solving for x:
-4x + 6 = 26
- 6 - 6
-4x = 20
/-4 /-4
x = -5
Answer:
B) x = -1 and x = 6
Step-by-step explanation:
The values that must be excluded from the domain are the values for which f(x) is undefined. Those values are the ones that make the denominator be zero.
We can find the zeros of the denominator by factoring.
... x² -5x -6 = (x +1)(x -6)
The product is zero when either factor is zero, so when x=-1 or x=6.
