using the formula:
y = mx +b
Using the given slope and coordinate points we get:
-1 = -3(2) + b
-1 = -6 + b
add 6 to each side
5 = b
y = -3x + 5
which is the same as:
3x + y = 5 ...answer choice a
Answer:
x=b/(ay)
Step-by-step explanation:
To make x the subject of the formula, we basically have to isolate the x.
To do this we first multiply both sides by x.
xy=b/a
Now, to isolate the x, we simply divide by y,
x=b/(ay)
So x=b/(ay) is our answer

Answer:
The probabilty of having at least one pink bulb if 4 bulbs are purchased is 13%.
Step-by-step explanation:
The proportion of pink bulbs is p=0.4.
If X is the amount of pink bulbs in a group of 4 bulbs, we can model this as a binomial distribution problem.
The probability that at least one of the bulbs is pink is P(X≥1)

The probabilty of having at least one pink bulb if 4 bulbs are purchased is 13%.
Answer: x=3
Step-by-step explanation:
4(2x-7)-2x=-10
Multiply 4 with 2x and -7
8x-28-2x=-10
Add like terms which are 8x and -2x
6x-28=-10
Add 28 to both sides so the -28 cancels out
6x=18
Divide both sides by 6 to isolate the x
Answer= x=3
