Answer:
133.2
Step-by-step explanation:
First take off the 40%
740 - (40/100)*740
740 - 0.4 * 740
740 - 296
444
=========================
That answer of 444 is the new selling price.
Now you take 30% of 444
30% of 444
30/100 * 444
0.3 * 444
133.2
Joseph will have to pay 133.2 dollars for the TV he want.
===========================
One Step
===========================
You could do this problem all in one step
30% (740*60% )
0.3 ( 740*0.6)
0.3(444)
133.2
=================
Both methods give the same answer.
First we need to found out how much you could buy WITHOUT coupon,
which is 2 shirts that cost $ 22.
You will have $5 Leftover.
Since you have a $6 dollar off coupon, you could buy one more t-shirt with
$ 5 (11 - 6 = 5)
So, the amount of t-shirt you could buy WITH coupon is 3 T-shirts.
The answer is B. Kristine is exactly 9 inches taller than Colleen

Answer:</h3>
y = -4x +2
<h3>
Step-by-step explanation:</h3>
The slope-intercept form of the equation for a line is conveniently found from the point-slope form. In either case, you need to know the slope. That is ...
... slope = m = (change in y)/(change in x)
For the first two points, the slope is ...
... m = (-6 -(-2))/(2 -1) = -4
Using the point-slope equation for slope m and point (h, k) written as ...
... y = m(x -h) +k
we can substitute m = -4 and (h, k) = (1, -2) to get ...
... y = -4(x -1) -2
... y = -4x +2 . . . . . . . simplify
Answer:
A. {u1,u2,u3,u4} is a linearly independent set of vectors unless one of {u1,u2,u3} is the zero vector.
Step-by-step explanation:
Given that u4 is not a linear combination of {u1,u2,u3}
This means there is no possibility to write u4 = au1+bu2+cu3 for three scalars a,b,and c.
This gives that 
This implies that these four vectors are not linearly dependent but linearly independent.
Hence option a is right.
A. {u1,u2,u3,u4} is a linearly independent set of vectors unless one of {u1,u2,u3} is the zero vector.
