The properties that justify the steps taken to solve the given system are as follows:

6x – 8y = 18, 2x + 8y = 6

[Multiplication property of equality]

8x = 24

[Addition property of equality]

x = 3

[Division property of equality]

3(3) – 4y = 9

[Substitution property of equality]

9 – 4y = 9

[Simplify]

-4y = 0

[Subtraction property of equality]

y = 0

[Division property of equality]

Identify each point as a solution of the system or not a solution of the system.

lubasha [3.4K]

Answer:

see below

Step-by-step explanation:

Plot the points on the given graph. The ones that fall in on a solid line at the edge of the doubly-shaded area, or fall in the doubly-shaded area, are part of the solution set.

(0, 4) on the dashed line — not a solution

(-2, 4) on red line in blue area — solution

(0, 5) in doubly-shaded area — solution

(–2, 7) in doubly-shaded area — solution

(–4, 1) in blue area — not a solution

(–1, 1) on red line outside blue area — not a solution

(–1.5, 3.5) in doubly-shaded area — solution

Answer:

$\huge\boxed{8x^5y^7z^2}$

Step-by-step explanation:

$\text{Use}\ a^n\cdot a^m=a^{n+m}\\\\2x^2y^3z^2\cdot4xy^4x^2=(2\cdot4)(x^2xx^2)(y^3y^4)z^2=8x^{2+1+2}y^{3+4}z^2\\\\=8x^5y^7z^2$
