Answer:
-216 has three real cube roots.
Step-by-step explanation:
Answer:
(-2/7, 2/3)
step-by-step explanation:
-7x + 3y = 2
x = 0
-7(0) + 3y = 2
3y = 2
/3 /3
y = 2/3
y = 0
-7x + 3(0) = 2
-7x = 2
/-7 /-7
x = -2/7
(-2/7, 2/3)
Keep, change, flip
Example: 3/4 divided by 6/8
Step 1: keep 3/4
Step two: change the division sign to a multiplication sign
Step 3: flip 6/8 and make it 8/6
Step 4: multiply it, then that’s your answer to the division problem
you subtract the powers when dividing
therefore 7-(-4)
=7+4
=11
=x^11
Answer:
21x + 7y -13
Step-by-step explanation:
You just need to add -5x to 26x, which equals 21x.
