Step-by-step explanation:
12 is rounded to 10
22 is rounded to 20
20×10= 200
Answer:
Step-by-step explanation:
Δx = 10-(-6) = 16
Δy = -3-11 = -14
(-6+16/3, 11-14/3) = (-⅔, 6⅓)
(10-16/3, -3+14/3) = (4⅔, 1⅔)
Answer:
Step-by-step explanation:
Best advice: make a sketch (which I can't do here).
When you reflect in the x axis, only the y value changes...so (3, -4) reflects to (3,4).
Translating down (i.e. in the negative direction) again means the x value (the abscissa) doesn't change, only the y value (the ordinate)...so the final value of the point is (3,1).
For this case we have a function of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: decrease rate
t: time
Substituting values we have:
y = 200 * (0.946) ^ t
Answer:
An exponential function showing the relationship between and and is:
y = 200 * (0.946) ^ t
X = -7 you can just look this up too
