X = 40, Y = 15
40(2) + 15(2) = 80 + 30 = 110 :)
Answer:
y = 128(4.926)^x
Step-by-step explanation:
Exponential function: y = ab^x
x = 0, y = 128
128 = ab^0
128 = a
--------------------
a = 128, y = 371,293, x = 5
371,293 = 128 x b^5
b^5 = ( 371,293 / 128 )
b = (fifth root) 5^√2900.7265625
b ≈ 4.926
----------------------------------------
y = 128(4.926)^x
I hope this helps!
So according to the question statements
6% of the $40k and 7$ of the second $40k and 9% ammount of the $80k
the answer would be
40000 * 0.06
+ 40000 * 0.07
+ 25000 * 0.09
= 270250
Answer:
I will assume that the term "x+2/2" is meant to be "(x + 2)/2)." Otherwise the equation would read (x/3) = x + 1
Step-by-step explanation:
(x/3) = (x + 2)/2
x = 3*(x+2)/2 [Multiply both sides by 3]
x = (3x + 6)/2
x = (3/2)x + 6/2
x - (3/2)x = 3
-0.5x = 3
x = -6
====================
Check:
Does (x/3) = (x + 2)/2 for x = -6?
(-6/3) = (-6 + 2)/2
-2 = -4/2
-2 = -2 YES
Answer:
135°
Step-by-step explanation:
Considering it's estimation, there isn't too much of an explanation, but here you go anyways.
A straight angle is equal to 180°. DBE is a straight angle.
DBC and CBE added together appear to be 180° (supplementary).
We are trying to find DBC. An obtuse angle has to be over 90°, which in this case DBC clearly is over 90°. From that you can conclude it isn't any of the first 3, so it's D. 135°
hope this helps and give brainliest if I am epic blah blah blah ;)
