What is the product?

Mathematics
1 answer:
vagabundo [1.1K]3 years ago
8 0

Answer:

So option B is the correct answer .

Step-by-step explanation:

Since it is the multiplication of 1 X 3 matrix to 3 X 3 order matrix,

so the resultant product should be 1 X 3 because when we multiply two matrices it is the condition that if A is of order p X q and B is of order q X r,

the product matrix (suppose C ) will be of order p X r.

so the product will be

= [-1*3+2*2+4*0   -1*6+2*4+4*6   -1*1+2*0+4*2]

= [ 1      26     7] .

You are ordering pencils from Amazon for $3.50 each. Shipping costs an additional $2.99. This situation can be represented with
DENIUS [597]

Answer:

Y=total cost of purchasing the pencils

Step-by-step explanation:

Y=3.5x+2.99

Where,

Y=total cost of purchasing the pencils

3.5=price of each pencil

X= number of pencils bought

2.99= shipping cost

For instance, if you order for 5 pencils on Amazon, the total cost of purchasing it is

Y=$3.50(5)+$2.99

Y=$17.50+$2.99

Y=$20.49

Select all answers that have a value of 22?? Help..
Tom [10]

Let's plug in the variables one by one.

6g - 2h

plug in 5 for g and 4 for h

6(5) - 2(4)

multiply

30 - 8

subtract

→ 22

20g

plug in 2 for g

20(2)

multiply

40

2(g + 1)

plug in 10 for g

2(10 + 1)

add

2(11)

multiply

→ 22

4g + 5h

plug in 1 for g and 4 for h

4(1) + 5(4)

multiply

4 + 20

add

24

Therefore, the answers that have a value of 22 are 6g - 2h and 2(g + 1)

Parallelogram ABCD has vertex coordinates a(0,2) b (6,2) c (8,6 and d (2,6) write a rule to find the vertex coordinates of a par
Anastasy [175]

Answer:  The rule is explained.


Step-by-step explanation:  As shown in the attached figure, ABCD is a parallelogram with vertices A(0,2), B(6,2), C(8,6) and D(2,6).

Suppose, we are to find the vertices of a parallelogram PQRS that is smaller than but similar to ABCD, then we can follow the following rule.

Let us consider a positive real number k. Then the new coordinates of smaller and similar parallelogram PQRS will be

Co-ordinates of P will be (k,2+k),

Co-ordinates of Q will be (6-k,2+k),

Co-ordinates of R will be (8-k,6-k)

and

co-ordinates of S will be (2+k,6-k).

Taking any positive real value of k, we will get a new, smaller parallelogram which will be similar to ABCD.
