Answer:
<u>The equation that represents Samantha's total pay as a function of her total sales is B. y = 0.2x + 325</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Total Sales Total Pay
Week 1
$ 500
$ 425
Week 2 $ 350 $ 395
2. Let's find out the equation that represents Samantha's total pay as
a function of her total sales, this way:
Week 1:
A) y = 0.6x + 125 = 0.6 * 500 + 125 = 300 + 125 = 425 Correct
B) y = 0.2x + 325 = 0.2 * 500 + 325 = 100 + 325 = 425 Correct
C) y = 1.6x - 95 = 1.6 * 500 - 95 = 800 - 95 = 705 Incorrect
Week 2:
A) y = 0.6x + 125 = 0.6 * 350 + 125 = 210 + 125 = 335 Incorrect
B) y = 0.2x + 325 = 0.2 * 350 + 325 = 70 + 325 = 395 Correct
C) y = 1.6x -95 = 1.6 * 350 - 95 = 560 - 95 = 465 Incorrect
<u>The equation that represents Samantha's total pay as a function of her total sales is B. y = 0.2x + 325</u>
Answer:
(b) Function B
Step-by-step explanation:
The exponent of 2 in Function B tells you it is nonlinear. A linear function will not have any product of variables or any roots.
You know function A is linear because the differences in x-values are all the same, and the differences in y-values are all the same. What makes it linear is that the ratio of y-differences to x-differences is a constant:
Δy/Δx = (8 -10)/(2 -0) = -1 = (6 -8)/(4 -2) = (4 -6)/(6 -4)
__
Function B is nonlinear.
Answer:
assuming x2 is x^2:
f(x) = (x+4)^2 - 3
Step-by-step explanation:
1. move c to f(x) side
2. make sure a=1
3. (b/2)^2
4. add the solution of 3 on both sides
5. factor the right side using the shortcut
6. add c back to the other side
Answer:
6 4/39
Step-by-step explanation:
The above is the answer because you are just adding a whole number and a fraction which is what mixed numbers/mixed fractions are.
