We have two equation with two unknowns. Therefore, we can solve the x and y easily. There are a number of methods to apply here but I will be using substitution method. We do as follows:
-2x + y = 1
y = 1 + 2x
4x + y = -1
4x + 1 + 2x = -1
6x = -1 -1
6x = -2
x = -1/3
y= 1 + 2(-1/3)
y = 1/3
Answer:
x = -2/3 or 4/5
Step-by-step explanation:
-15r^2 + 2r + 8
Answer:
x+20 ≤ x²+9
Step-by-step explanation:
the options you gave didnt have any square options, so imma just guess you meant this? if not, let me know.
Times by 3. Then divide the top backup by 3 to get 9/30. 9/30+9/30+9/30=27/30=9/10.
