Hello there!
The correct answer is option A, because:
4(t - 6)
Use the distributive property
(4)(t) + (4)(-6)
So yeah, this is how the distributive property works.
Option A is the only option that works with the distributive property.
Let me know if you have questions about the answer. As always, it is my pleasure to help students like you!
3n-3x-15 You have to add the like terms.
I = Prt
Interest on CD = 0.0425 x $1,800 = $76.5
Interest on savings = 0.0275 x $1,800 = $49.5
Difference of interest on CD and Interest on savings = $76.5 - $49.5 = $27
Therefre, he will earn $27 more if he invest in a CD rather than in a savings.
<h3>that's what I can find out about the sum. sorry if I solved it wrong.</h3>
Answer: choice A) -6
-----------------------------------------------
Work Shown:
Plug in x = 1
f(x) = 17-x^2
f(1) = 17-1^2
f(1) = 17-1
f(1) = 16
Then plug in x = 5
f(x) = 17-x^2
f(5) = 17-5^2
f(5) = 17-25
f(5) = -8
So the average rate of change (AROC) from x = 1 to x = 5 is...
AROC = (f(b)-f(a))/(b-a)
AROC = (f(5)-f(1))/(5-1)
AROC = (-8-16)/(5-1)
AROC = (-24)/(4)
AROC = -6
That's why the answer is choice A) -6
