suppose y varies directly with x and y = 14 when x = -4 what is the value of y when x = -6
here`s the answers
1. D 21
2. C 201.6
3. B 3/4
4. A 1/4
5. B 200
Thank you, I'm a grandfather trying to help my grandson.
The answers as of 2019 are:
1. D which is 21
2. C which is 201.6
3. B which is 3/4
4. A which is 1/4
5. B which is 200
(Awnsers is correct but I'm including it again for future kiddos whos letter choices might change up.) Also good luck in school guys yall got this. If yall have this quickcheck it means you're in 9th grade!! Only 3 years left!! DON'T quit!!! You got this, seriously!!!
y = kx , where k is a constant
for the given:
14 = k(-4)
k = -7/2 or -3.5
y = -3.5x
when x = -6
y = -3.5(-6) = 21
trust those answers
awnsers is right
They are actually:
1. D(21)
2. C(201.6)
3. B(3/4)
4. A
5. B(200)
Or, you can reason that since y=kx, y/x is constant. So,
14/-4 = y/-6
y=21
And you don't even have to figure out what k is.
