Answer:
6.67 miles per hour
Answer: m≤-0.45
Step-by-step explanation:
8*(10m+6)≤12
8*10m+8*6≤12
80m+48≤12
-48 -48
80m≤-36
:80 :80
m ≤ -36/80
m≤-9/20
m≤-0,45
The greatest common factor (GCF) of 40 and 44 is 4.
Explanation:
44 = 4 x 11
40 = 4 x 10
<em>44 + 40 =</em><span> (4 x 11) plus (4 x10) = </span><em>4 times (11+ 10)</em>
Answer:
9.25≤x≤64.15
Step-by-step explanation:
The smallest amount would be 5 of the least priced item
5 * 1.85 =9.25
The largest amount would be 5 of the greatest priced item
5 * 12.83 =64.15
9.25≤x≤64.15
Answer:
Since y is a solution of the homogeneus system then satisfies Ay=0.
Since z is a solution of the system Ax=b then satisfies Az=b.
Now, we will show that A(y+z)=b.
Observe that A(y+z)=Ay+Az by properties of the product of matrices.
By hypotesis Ay=0 and Az=b.
Then A(y+z)=Ay+Az=0+b=b.
Then A(y+z)=b, this show that y+z is a solution of the system Ax=b.
