Answer:
b) 2x + y = -4
Step-by-step explanation:
To go from the Point-Slope Formula [y - y₁ = m(x - x)₁] to the Slope-Intercept Formula [y = mx + b], move -1 to the RIGHT side of the equivalence symbol to get this: y = -2x - 4. Although this is a correct answer choice, this is NOT what the question is looking for because you have to go an extra step further, Standard Formula. To go from the Slope-Intercept Formula to the Standard Formula [Ax + By = C], move 2x to the LEFT side of the equivalence symbol, and you will end up with this: 2x + y = -4. So, your answer is b).
(60(100-5)/100)(100+5)/100
60(95/100)(105/100)
60(.95)(1.05)

Answer: x > -12
-2x + 12 < 36
Subtract 12 from both sides
-2x < 24
Divide both sides by -2
Because you divided by a negative number, flip the sign
x > -12
Check
Choose a value for x
-11 > -12
-2(-11) + 12 < 36
22 + 12
34 < 36; is True
Answer:
There are 15600 ways to pick a password
Step-by-step explanation:
We have 26 possibilities to pick a letter. So, we have 26 possibilities for the first component of the password. The second letter should be different from the first one, so we have one less possibility, giving us a total of 25, and for the third letter we have 24.
This gives us 26*25*24 = 15600 ways of picking a password.
