Answer:
-96
192
-384
Step-by-step explanation:
Multiply by negative 2
Answer:
12
Step-by-step explanation:
Let Brandon's age be = b years
Let Michael's age be = m years
As Michael is 12 years older than Brandon, Michael's age, so
Seventeen years ago, Michael was 4 times as old as Brandon, so
Substitute m=b+12
Hence, Brandon's age is 21 years
As m=b+12
Hence, Michael's age is 33 years.

Answer:
Hence, the model that best represents the data is:
Step-by-step explanation:
We are given a table that shows the estimated number of lines of code written by computer programmers per hour when x people are working.
We are asked to find which model best represents the data?
So for finding this we will put the value of x in each of the functions and check which hold true that which gives the value of y i.e. f(x) as is given in the table:
We are given 4 functions as:
A)
B)
C)
D)
We make the table of these values at different values of x.
x A B C D
2 66.66 49.3 52.5 50
4 94.57 71.44 106.3 104
6 134.14 103.57 160.1 158
8 190.27 150.14 213.9 212
10 269.91 217.64 267.7 266
12 382.85 315.5 321.5 320.
Hence, the function that best represents the data is:
Option C.
y=26.9x-1.3
The exponential function gotten from the table is y = 34(1.204)ˣ
An exponential function is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier.
Let y represent the lines of code written by x people.
From the table using the points:
(2,50) and (12, 320)
At (2, 50):
50 = ab² (1)
At (12, 320):
320 = ab¹² (2)
From equation 1 and 2:
b = 1.204, a = 34
The exponential function gotten from the table is y = 34(1.204)ˣ
