Answer:
6,271
Step-by-step explanation:
For x = 20 days: f(20) = 33(1.3)^20 = 33(190.0496377) = 6,271
Answer:
y = -3x - 16
Step-by-step explanation:
Point-slope form: y - y1 = m(x - x1)
Given: y - 2 = -3(x + 6)
Slope-intercept form: y = mx + b
To write the equation in slope-intercept form, we need to know the slope(m) and the y-intercept(b). By looking at the given equation, we can see that the slope is -3. We are also given the value of one point: (-6, 2).
To find the y-intercept, input the given values of the slope and the point into the equation format and solve for b:
y = mx + b
2 = -3(-6) + b
2 = 18 + b
Subtract 18 from both sides of the equation to isolate b:
2 - 18 = 18 - 18 + b
-16 = b
The y-intercept is -16.
Now that we know the slope and the y-intercept, we can write the equation:
y = -3x - 16
Answer:
21.142
Step-by-step explanation:
not sure it's correct
Answer:
5 is congruent, 6 is not congruent
Step-by-step explanation:
In 5, both shapes have the same side lengths. This means their areas are the same, making them congruent.
In 6, the shapes do not have the same side lengths. This means their areas are not the same, making them not congruent.
Answer:
He would pay a total of $21.50
Step-by-step explanation:
A trick that I learned is to take the zeros and decimals off. Then multiply. Ex) 75 × 2 =150. Take away the zero (15) and ad the decimal (1.5)
I'm not the best at explaining but I hope this helps
