Answer:
the first and last options
Step-by-step explanation:
option 1 is simply -21x/4 -21
last option is clearly equivalent to the question
If you would like to solve the system of equations 2x + y = -4 and y = 3x + 2, you can do this using the following steps:
<span>2x + y = -4
y = 3x + 2
</span>_________
<span>2x + y = -4
</span>2x + 3x + 2 = -4
5x = -4 - 2
5x = -6
x = -6/5
y = 3x + 2 = 3 * (<span>-6/5) + 2 = -18/5 + 10/5 = -8/5
</span>
(x, y) = (-6/5, -8/5)
The correct result would be (-6/5, -8/5).
Answer:
y=3x+2
Step-by-step explanation:
-2's opposite is positive and the rate of change (slope) is constant
