What is the solution for the system? Use the graph below y-x=-3 (line a)
y+x=3 (line b)

A. (0,3)
B. (-3,0)
C. (0,-3)
D. (3,0)

Answers

If you would like to know what is the solution for the system of equations, you can calculate this using the following steps:

y - x = - 3
y + x = 3
_______________
y - x + y + x = - 3 + 3
2y = 0
y = 0

y - x = - 3
0 - x = - 3
x = 3

(x, y) = (3, 0)

The correct result would be D. (3, 0).

Which subtraction expression has the difference 1 + 4i?

a. (–2 + 6i) – (1 – 2i)

b. (–2 + 6i) – (–1 – 2i)

c. (3 + 5i) – (2 – i)

d. (3 + 5i) – (2 + i)

Answers

If you would like to know which subtraction expression has the difference 1 + 4i, you can calculate this using the following steps:

a. (–2 + 6i) – (1 – 2i) = –2 + 6i – 1 + 2i =  –3 + 8i

b. (–2 + 6i) – (–1 – 2i) = –2 + 6i + 1 + 2i =  –1 + 8i

c. (3 + 5i) – (2 – i) = 3 + 5i – 2 + i = 1 + 6i

d. (3 + 5i) – (2 + i) = 3 + 5i – 2 – i = 1 + 4i

The correct result would be d. (3 + 5i) – (2 + i).

Answer:

(3 + 5i) – (2 + i)

A warehouse worker ships 25 boxes each day. Every box contains 3 shipping labels. Inventory has 500 shipping labels. How many days will it take to use the inventory of shipping labels? round to the nearest whole.

Answers

Answer: It will take 7 days to use the inventory of shipping labels.

Step-by-step explanation:

Given : Total boxes shipped by warehouse worker per day = 25

Every box contains 3 shipping labels.

Inventory has 500 shipping labels.

Then, the total number of boxes can be made =  (Total  shipping labels) ÷ (labels in each box)

500 ÷ 3  =166.67≈166

Number of days it will take to use the inventory of shipping labels=  (total number of boxes can be made)  ÷  (Total boxes shipped  per day)

= 166÷ 25=6.64≈7

Hence, it will take 7 days to use the inventory of shipping labels.

Factor completely 4x2 − 81.(4x − 9)(x + 9)

(2x + 9)(2x + 9)

(2x + 9)(2x − 9)

(2x − 9)(2x − 9

Answers

The factored expression of 4x^2 - 81 is (2x - 9)(2x + 9)

The expression is given as:

4x^2 - 81

Express 4 as the square of 2.

So, we have:

2^2x^2 - 81

Rewrite the expression as:

(2x)^2 - 81

Express 81 as the square of 81

(2x)^2 - 9^2

Rewrite the expression as the difference of two squares

(2x - 9)(2x + 9)

Hence, the factored expression of 4x^2 - 81 is (2x - 9)(2x + 9)
