Answer:
t=5.20s
Step-by-step explanation:
I think that is the expression because it say he purchases two bags, all the bags are 5.20 so he brought two bags which are school bag and one hand bag the formula I used was y=mx+b but in these case I had to put t=5.20x. I hope this really helped you..
Answer:
4
Step-by-step explanation:
This is a substitution question
So we will have to substitute the value of x given into the given question
f(x)=8^x
And x is given as 2/3
So let's get to work
8^2/3 which means that cube root of 8 then square the answer
(3√8)^2
Cube root of 8 is 2
So we will have to square 2 to get 4
Therefore the final answer is 4
I believe you understand
Answer:
28
Step-by-step explanation:
2(3y + 4 + 2) = 196 − 16
6y + 8 + 4 = 196 - 16
6y + 12 = 196 - 16
6y + 12 = 180
6y = 168
y = 28
Best of Luck!
Answer:
Proportionality constant = 
Step-by-step explanation:
Let y ∝ x
y = kx
Here, k = proportionality constant
From the table attached,
If x = 2 and y = 3,
3 = 2k
k =
If x = 4 and y = 6,
6 = 4k
k = 
k =
Since, k = is constant in every condition, table represents the proportional relation with proportionality constant .
