Answer:
537.47712
Step-by-step explanation:
a = 125 ... the first term?
r = 1.2
ok use the formula: a_n = (a_1) * r ^(n-1)
we want a_9 = (a_1) * r^(9-1)
a_9 = 125 * (1.2)^8 = 125 * 4.29981696 = 537.47712
You can use two negative numbers and add them to get -6. An example can be -4+-2=-6
Answer:
13 - 2 = 11

Answer:
Step-by-step explanation:
Firstly you must understand you want to get the value of y.
So put in values into equation which make x.
To understand here lets look at y = 0
if y is to be 0 then x is 3.
If we substitute this value into equation (B) we get the result.
Now we have identified our answer, all is left is to substitute all other values of x and see if y are true.
So , we can see B is the answer
Your answer is D. a = 2, b = -3, c = -27.
This is because to use the quadratic formula, your equation needs to equal 0, and to do that, you need to subtract 27 and 3x from the right to get 2x² - 3x - 27 = 0, and since the -3 is the x value, we use it for b.
I hope this helps!
