Y + yx; use x = 15, and y = 8

128

Step-by-step explanation:

y+yx

When x=15, y=8

8+(15×8)

=8+120=128

128

Step-by-step explanation:

from the quetsion, given that

y + yx = ?

given that x = 15

y = 8

all we need to do is to substitute for the values of x and y in the question and evaluate.

y + yx =

= 8 + 8 x 15

= 8 + 120

= 128

answer

the correct answer is

explanation

the given function is

the excluded values are obtained by solving:

we factor to obtain:

the excluded values are

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
