5(v+2) = -2(7v-3) + 9
------------------------------------
Distribute:
5v + 10 = -14v + 6 + 9
Combine Like Terms
5v + 10 = (-14v+9v)+6
5v + 10 = -5v + 6
Subtract -5v from both sides
10v + 10 = 6
Subtract 10 from both sides
10v = -4
Reduce
5v = -2
Divide both sides by 5
v = -2/5
Simplify
v = -0.2
Answer:
-8b + 9 - 5k
Step-by-step explanation:
I am assuming the blue highlighted portion is your answer, and is not a part of the initial question
(-4b + 15 - 7k) - (6 + 4b - 2k)
Combine like terms
-4b - + 4b
Negative + Positive = Negative
-4b - 4b = -8b
15 - 6 = 9
-7k - - 2k
Negative + Negative = Positive
-7k + 2k = -5k
Put them all together:
0b + 9 - 5k
Simplify
-8b + 9 - 5k
I got the same answer as you (just in a different order)
The answer is c because it is the inverse of the function.
Answer:
Our score = 0.60, Amanda's score = 0.25
Step-by-step explanation:
For Amanda
μ = 15 , σ = 4
z- score for X = 16 is (From z table)
z = (X - μ)/σ = (16 - 15)/4 = 0.25
For us
μ = 310 , σ = 25
z score for X = 325 (From z table)
z = (325-310)/25 = 0.60
Since our z score is better than Amanda's z score, we can say we did better
You need 1 cups and 2/3 more.
