Answer:
<em>Answer: The point (1, 2) is not a solution to the system of equations because it does not satisfy the equation 3x + y = –2.</em>
Step-by-step explanation:
<u>System of Equations</u>
Consider the following system of equations
2x + 3y = 8 [1]
3x + y = -2 [2]
And the point (1,2). Substituting in both equations:
For equation [1]:
2*1 + 3*2 = 8
2 + 6 = 8
8 = 8
Since the equation is true, point (1,2) satisfies the equation 2x + 3y = 8
Now for equation [2]:
3*1 + 2 = -2
3 + 2 = -2
5 = -2
Since this equation is false, point (1,2) does not satisfy the equation 3x + y = -2
Answer: The point (1, 2) is not a solution to the system of equations because it does not satisfy the equation 3x + y = –2.
Hello :
8000 = 8 ×1000 = 2 ^3 ×10^3 = 20 ^3
note; identity b^3 +a^3 = (a+b) (a²+b² - ab)
in this exercice : b=20
so : 8000+b^3 = (a+20)(a²+400 - 20a).... <span>Factor the following</span>
Answer:
answer 12.5
Step-by-step explanation:
25% of 50 is 12.5 because 50 ÷ 4 = 12.5 Hope that helps!
