Answer:
yes to 5, and no to -7 (only because we are dealing with real positive numbers, not imaginary numbers). the domain is all real numbers greater than or equal to 2
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
Multiply the second equation by −2 to get −4x − 12y = −48.
Step-by-step explanation:
Given:
4x + y = 4 (1)
2x + 6y = 24 (2)
Multiply the second equation by −2 to get −4x − 12y = −48.
4x + y = 4 (1)
−4x − 12y = −48 (3)
Variable x can be eliminated by adding the equations
4x + (-4x) + y + (-12y) = 4 + (-48)
4x - 4x + y - 12y = 4 - 48
0 - 11y = -44
-11y = -44
Divide both sides by -11
y = -44/-11
= 4
Write 343 w/ an exponent by using 7 as the base.
7^3
It doesn't, it ends after 32 digits after 0.
