Answer:
that would be roughly 38 pounds
Step-by-step explanation:
First, we’re going to use this formula:
2nd number - 1st number
————————————— x 100%
1st number
If we plug in the numbers to this equation:
23-20
———- x 100%
20
And subtract 23 to 20, the answer to this equation is:
3
—- x 100% = 15%
20
In this case, the percent of increase is 15%.
Answer:
61
Step-by-step explanation:
Givens
Let the pizzas = x
Let the sodas = y
Equation
y = 3x + 2
<u>Part A</u>
y = 3*8 + 2
y = 24 + 2
y = 26
<u>Part B</u>
Sodas = 26* 1.25 = 32.50
Pizzas =9.50 * 3 = 28.50
Total for both = 32.50 + 28.50 = 61
Answer:

Step-by-step explanation:
Given 
Let 
Interchange x and y

Solve for y, by first squaring both sides


Hence

The last choice is correct
Answer:
y-intercept (0,1)
multiplicative rate of change: b
Step-by-step explanation:
If a table represents an exponential function of the form
, then the y-value that corresponds to x=0 is 1.
In other words, the y-intercept (0,1) must be present in the table.
Also the ratio of a subsequent y-value to the previous y-value should give a value of b.
In other words the multiplicative rate of change from the table must be equal to b.
