Answer: a-b+c+d =4
Step-by-step explanation:
The given system of equation is
from this we have the following matrices
the given matrix A =
On comparing Matrix 
with Matrix A
we have the following values
a=2 ,b=4,c=8,d=-2
Thus a-b+c+d =2-4+8+(-2)=4
Answer:
y=4x + 3/4
Step-by-step explanation:
Answer:
The numbers are 35 and 28
35+28=65
35-28=7
Step-by-step explanation:

By looking at the graph you can rule out choices C and D because the graph given to you is an increasing linear function and C and D represent functions with a decreasing or negative slope.
By looking at the picture the slop of the graph seems to be 4/1 (rise/run) so your slope is 4. And your y-intercept looks like its -4 so your answer is B<span />
7/8 because 3/4 = 6/8, and 7/8 is bigger than 6/8
