Answer:
y = 1.6 x
y = 24
Step-by-step explanation:
The general equation of a direct variation is
y = k x
In this case
x = 10
y = 16
y = k*x
16 = 10*k
16/10 = k
k = 1.6
y = 1.6x
================
Let x = 15
y = 1.6 * 15
y = 24
Answer:
56.70
Step-by-step explanation:
first determine the tax
45 * 6% = 45*.06 = 2.70
Then determine the tip
45 * 20% = 45*.2 =9
Then add everything together
45+2.70+9 =56.70
Answer:
Roots are x=6 and - 4
Step-by-step explanation:
2(x-6)(x+4)=0
(x-6)=0 or (x+4)=0
x=6 or x=-4, their multiplicities is 1
Answer:
The answer would be positive 6
Step-by-step explanation:
I know it is -6 because when you solve this you do...
-x = -6
Divide both sides by -6
-x/-6 = -6/-6
the answer would be 6
because a negative divided by a negative is a positive.
Hope this helps have a great day! :)
Answer:
Otieno's age in 4 years: 
Kidole's age in 4 years: 
Step-by-step explanation:
= Otieno's age
= Kidole's age
Their ages will increase by 4 years when 4 years pass.
= Otieno's age in 4 years
= Kidole's age in 4 years
= Kidole's age in 4 years (after simplifying the expression)
I hope this helps!
