Answer:
84 in^2
Step-by-step explanation:
Find the area by first finding the average of 10 and 14 (it is 12) and then multiplying this result (12) by 6: area of trapezoid = 84 in^2.
Answer:
1
Step-by-step explanation:
Take any two points from the line:
I will take (-1,0) (0,1)
slope formula:
m = y2 - y1 / x2 - x1
m = 1 - 0 / 0 - (-1)
m = 1 / 0 + 1
m = 1 / 1
m = 1

Answer:
x<120
Step-by-step explanation:
-30<x/-4
In order to simplify this, we must isolate the x value by multiplying both sides by -4
Since we are dealing with inequalities and we are multiplying by a negative number, we have to switch the sign (<,>)
-30(-4)>x
x<120
Answer:
is this all the info or...?
Step-by-step explanation:
Step-by-step explanation:
If T:Rn→Rm is a linear transformation and if A is the standard matrix of T, then the following are equivalent:
1. T is one-to-one.
2. T(x) = 0 has only the trivial solution x=0.
3. If A is the standard matrix of T, then the columns of A are linearly independent.
Here, A is a mxn matrix where m ≥ n and the rank of A equals n. It implies that the columns of A are linearly independent, for, otherwise, the rank of A would be less than n. Hence the linear transformation represented by A is one-to-one.
