X3=0.6666
Answer: If you want me to simplify, the answer is -4y - 7.
Step-by-step explanation: Just add the like terms (-4 and -3) to get -7. Then you have the y, which gives you -4y - 7.
Answer:
x² - x + 6
Step-by-step explanation:
note (f + g)(x) = f(x) + g(x)
f(x) + g(x)
= x² + 1 + 5 - x ← collect like terms
= x² - x + 6
-7 is the y-intercept
3 is the slope.
start point at -7 in the y-axis and then count 3 units up and 1 unit right and make another point. Then make a straight line through the two points. The line is infinite.
I hope you get it :)
