Answer:
good news, the second one is relatively easy because it can be factored to (2x+1)(2x-3) which means that number two has solutions of -1/2 and 3/2
but for number one you have to either use the quadratic equation cause I've tried using synthetic division or just use the second equation to derive the first solutions so I tried move the graph up by two units and found that the intercepts are approximately (1+-√2)/2 or 1/2+-1/√2 for 4x^2-4x-1
Answer:
Step-by-step explanation:
<u>∠4 and 158° are supplementary as same side interior angles</u>
- m∠4 + 158° = 180°
- m∠4 = 180° - 158° = 22°
C=2pi2
c=12.56
so the last one
Answer:
Step-by-step explanation:
b.
(0,2)
2y - x > 1
2(2) - 0 > 1
4 - 0 > 1
true, (0,2) is a solution to the inequality
(8,1/2)
2y - x > 1
2(1/2) - 8 > 1
1 - 8 > 1
-7 > 1
false, (8,1/2) is not a solution to the inequality
(-6,3)
2y - x > 1
2(3) - (-6) > 1
6 + 6 > 1
12 > 1
true, (0,2) is a solution to the inequality
(-7,-3)
2y - x > 1
2(-3) - (-7) > 1
-6 + 7 > 1
1 > 1
false, (8,1/2) is not a solution to the inequality
(1 is not greater than one, but equal. since the inequality is not "greater than or equal to", this equation is false)
c. the top half should be shaded
d. no, because the inequality is >, not >=. therefore, the points on the line are not included in the solution set.
