The choices are:
<span>A.
The student identified the greatest common factor incorrectly.
B.
The student incorrectly divided each term by the greatest common factor.
C.
The student failed to simplify the expression.
D.
The mathematical work shown is correct.</span>
I think the correct answer from the choices is option D. The mathematical work shown is correct. Hope this answers the question. Have a nice day.
1: -5 = 3m + c
2: -2 = 0 + c
From equation 2, we knew c = -2
So we sub into equation 1 and got the value of m
-5 = 3m - 2
m = -1
The equation of line is y = -x - 2
Answer:
g(t) = 10000(0.938)^t
Step-by-step explanation:
Given data:
car worth is $10,000 in 2012
car worth is $8000 in 2014
let linear function is given as
P(t) = at + b
which denote the value of car in year t
take t =0 for year 2012
at t =0, 10,000 = 0 + b
we get b = 10,000
take t =2 for year 2014
at t =2, P(2) = 2a + b
8800 = 2a + 10,000
a = - 600
Thus the price of car at year t after 2012 is given as p(t) = -600t + 10000
let the exponential function 
where t denote t = 0 at 2012
putting t = 0 P(0) = 10,000 we get 10,000 = ab^0
a = 10,000
putting t = 2 p = 8800
b = 0.938
g(t) = 10000(0.938)^t

Answer:
24 feet
Step-by-step explanation:
The side adjacent to the angle is given, and the hypotenuse of the triangle is the unknown. The cosine relation applies:
Cos = Adjacent/Hypotenuse
hypotenuse = ladder length = (5 ft)/cos(78°) ≈ 24.0 ft
The ladder is about 24 feet long.
