Step-by-step explanation:
The y-intercept is +4 for both lines, so only the third selection is appropriate. The lines appear to have a slope of magnitude less than 1, so ±1/2 seems about right.
(We expect at least one of the inequality symbols to include the "or equal to" case so there is no hole at x=0. Alas, it seems the third answer choice doesn't do that.)
Answer:
x = ± 
Step-by-step explanation:
3x² + 7 = 28 ( subtract 7 from both sides )
3x² = 21 ( divide both sides by 3 )
x² = 7 ( take square root of both sides )
x = ± 
that is x = -
, x = 
Answer:
-6 = x / 3 -Multiply both sides by 3
-6 * 3 = x / 3 * 3
-18 = x
Now, you can check your answer:
-6 = -18 / 3
-6 = -6
Hope this helps!
