Answer:

x = - 2, y = 1

Step-by-step explanation:

Comparing both the equations,

→ y = y → x + 3 = - 2x - 3

=> x + 3 = - 2x - 3

=> x + 2x = - 3 - 3

=> 3x = - 6

=> x = - 6/3 = - 2

Answer:

Step-by-step explanation:

If a solution exists for the system of equations y=y so we can say

x+3=-2x-3 Add 2x to each side

3x+3=-3 Subtract 3 from each side

3x=-6. Divide each side by 3

x=-2, since y=x+3

y=-2+3

y=1

So the solution to the system of equations is the point (x,y)=(-2,1)

What is the monomial if a square of a monomial is: 0.0001*a^8*x^4
Georgia [21]

Answer:

Monomial 0.0001\cdot a^8\cdot x^4 is a square of monomial 0.01\cdot a^4\cdot x^2

Step-by-step explanation:

Given monomial 0.0001\cdot a^8\cdot x^4

Using property (a^m)^n=a^{m\cdot n}, note that

0.0001=(0.01)^2\\ \\a^8=(a^4)^2\\ \\x^4=(x^2)^2

So,

0.0001\cdot a^8\cdot x^4=(0.01)^2\cdot (a^4)^2\cdot (x^2)^2.

Now use property (a\cdot b)^n=a^n\cdot b^n to rewrite the previous expression:

(0.01)^2\cdot (a^4)^2\cdot (x^2)^2=(0.01\cdot a^4\cdot x^2)^2

Hence, monomial 0.0001\cdot a^8\cdot x^4 is a square of monomial 0.01\cdot a^4\cdot x^2
