Answer: B) 12.5

Step-by-step explanation:

Start by isolating x by subtracting 2.5 from both sides

$x+2.5 < 20\\x+2.5-2.5 < 20-2.5\\x < 17.5$

This reads as "x is less than 17.5"

D can be eliminated because it is greater than 17.5

C can be eliminated because 17.5 can't be less than itself

So the answer must be B since it is less than 17.5 and greater than A

Answer: x<17.5

Step-by-step explanation:

Subtract from both sides: x+2.5-2.5<20-2.5

Simplify the arithmetic: x<20-2.5

Simplify the arithmetic: x<17.5

Hope it helps!

Mark the statement either true (in all cases) or false (for at least one example). If false, construct a specific example to sho

Answer with Step-by-step explanation:

We are given that $v_1,v_2,..,v_4$ are in $R^4$ and $v_1,v_2,v_3$ is linearly dependent then {v_1,v_2,v_3,v_4}[/tex] is also linearly dependent.

We have to find that given statement is true or false.

Dependent vectors:Dependent vectors are those vectors in which atleast one vector is a linear combination of other given vectors.

Or If we have vectors $x_1,x_2,....x_n$

Then their linear combination

$a_1x_1+a_2x_2+.....+a_nx_n=0$

There exist at least one scalar which is not zero.

If $v_1,v_2,v_3$ are dependent vectors then

$a_1v_1+a_2v_2+a_3v_3=0$ for scalars $a_1,a_2,a_3$

Then , by definition of dependent vectors

There exist a vector which is not equal to zero

If vector $v_3$ is a linear combination of $v_1\;and \;v_2$ , So at least one of vectors in the set is a linear combination of others and the set is linearly dependent.

Hence, by definition of dependent vectors

{ $v_1,v_2,v_3,v_4$ } is linearly dependent.

Option B is true.

The graph shows the relationship between the total cost. The true statement is

Seven erasers cost $3.50. Option D

This is further explained below.

<h3>The graph shows the relationship between the total cost and the number of erasers bought at the student store. Which statement is true?</h3>

Generally, A cost is the worth of the money that has been spent in the process of producing something or delivering a service, and as a result, it is no longer accessible for use.

This concept is utilized in manufacturing, research, retail, and accounting. In the world of business, a cost may refer to a purchase, in which case the sum of money spent on the item in question is considered to be the cost of the item.

In conclusion, each eraser will cost u 50 cents

so 7 erasers will cost (7 * 0.50) = 3.50
