The first numbers are three and six and the second numbers are 2 and four
Answer:
A. 13%
Step-by-step explanation:
let's suppose there's 1000 bars of chocolate in general
70 % dark = 700 dark choco bars
30 % milk = 300 milk choco bars
20 % have nuts = 200 bars have nuts
80 % don't have nuts = 800 bars don't have nuts
if 90 % of dark chocolate bars don't have nuts, that means 630 dark chocolate bars don't have nuts, but 70 have nuts
200 bars in general have nuts, if only 70 dark chocolate bars have nuts,
200 - 70 = 130
130 = 13%
The expression y = 4.998 · is the exponential function that passes through the points (- 1, 5 / 3) and (3, 135).
<h3>How to derive an exponential function that passes through two given points</h3>
Herein we find the location of two points set on Cartesian plane that belongs to an exponential function of the form:
Where:
- A - y-Intercept of the exponential function.
- B - Growth factor
- x - Independent variable.
- y - Dependent variable.
Which is equivalent to the following logarithmic expression:
㏑ y = ㏑ A + B · x
If we know that (x₁, y₁) = (- 1, 5 / 3) and (x₂, y₂) = (3, 135), then the following system of equations is generated:
㏑ (5 / 3) = ㏑ A - B
㏑ 135 = ln A + 3 · B
Then, we solve the system by numerical methods:
㏑ A = 1.609 (A = 4.998), B = 1.098
And the exponential function is equal to y = 4.998 · .

Your correct answer is: 2y^3+28y-12
Let's simplify step-by-step.
6y3+17y−3−(4y3−11y+9)
Distribute the Negative Sign:
=6y3+17y−3+−1(4y3−11y+9)
=6y3+17y+−3+−1(4y3)+−1(−11y)+(−1)(9)
=6y3+17y+−3+−4y3+11y+−9
Combine Like Terms:
=6y3+17y+−3+−4y3+11y+−9
=(6y3+−4y3)+(17y+11y)+(−3+−9)
=2y3+28y+−12
Answer:
=2y3+28y−12
