Answer:
The table a not represent a proportional relationship between the two quantities
The table b represent a proportional relationship between the two quantities
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
<u><em>Verify each table</em></u>
<em>Table a</em>
Let
A ----> the independent variable or input value
B ----> the dependent variable or output value
the value of k will be
For A=35, B=92 ---> 
For A=23, B=80 ---> 
the values of k are different
therefore
There is no proportional relationship between the two quantities
<em>Table b</em>
Let
C ----> the independent variable or input value
D ----> the dependent variable or output value
the value of k will be
For C=20, D=8 ---> 
For C=12.5, D=5 ---> 
the values of k are equal
therefore
There is a proportional relationship between the two quantities
The linear equation is equal to
Hello from MrBillDoesMath!
Answer:
f(x) = 8 * 3^x
Discussion:
x = 0: f(x) = 8
x = 1: f(1) = f(0) * 3 = 8*3
x = 2: f(2) = f(2-1)*3 = f(1) * 3 = (8*3)*3 = 8 * 3^2
x=3 : f(3) = f(3-1)*3 = f(2)*3 = (8 * 3^2) * 3 = 8 * 3^3
Based on this we guess that
f(x) = 8 * 3^x
Thank you,
MrB
Only 4 because result is (x-4)(x-4) that means (x-4)^2=0
So
X-4=0
X=4

Step-by-step explanation:
Monday
1.) <em>1250 gallons of water for 1 ounce of Granular chlorine.</em>
<em></em>
2.) <em>w = 1250c</em>
Tuesday
9.5% of 50
0.095 × 50 = 4.75
<em>The fee costs $4.75</em>
Since the fee will be deducted from the selling price..
50 - 4.75 = 45.25
<em>Once he pays for the fee, he'll make $45.25.</em>

Wednesday
To get 1 cup of sugar, you multiply 4 to 1/4 meaning to find the proportional amount of flour used, you have to multiply 2/3 by 4
2/3 × 4 = 8/3
<em>She should use 2 ²/₃ cups of flour</em>
Since in the new recipe, we're multiplying everything by 4..
16 × 4 = 64
With this new recipe, she can make 64 cookies.
Thursday
4800 ÷ 6400 = 0.75
0.75 × 100 = 75
4800 is 75% of 6400
100 - 75 = 25
<em>So, the cost of health insurance for the family increased by 25%</em>
