Answer:
D. R(x)=850x+9600
Step-by-step explanation:
Use the given information as points on a line, and find the slope.
The two given points are (10, 18,100) and (20, 26,600).
slope = (difference in y)/(difference in x)
slope = (26,600 - 18,100)/(20 - 10)
slope = 8,500/10
slope = 850
Only choice D. has a slope of 850.
Answer: D. R(x)=850x+9600
Scalar multiplication of a matrix refers to the
multiplication of all the elements of the matrix by an ordinary number which is
called a scalar.
From the given options the statements which are true about
scalar multiplication of matrices are;
a)
You can
multiply a matrix of any size by a scalar.
b)
For any matrix A, 1 × A = A.
c)
Scalar multiplication is a shortcut for repeated
addition of the same matrix.
Answer:
Equations are
20c + 10m = 495..............(1)
8c + 1m = 178.5.................(2)
Now , equation (2) * 10 = 80c + 10m = 1785...........(3)
So, Eq. (3) - Eq(1) =
80c + 10m - 20c - 10m = 1785 - 495
60c = 1290
c= 21.5
********************************************************
Now place the value of c in Eq (2)
So , m =6.5
