Answer9
What is the equation for the line that passes through the point (0, 0) and has a slope of 1/2?
Answery=1/2x
Which is the solution of 2x + 5 > 1?
Answer
X > 6
X < 6
X > 2
None of these I believe the answer is this one

1. Given: (2,2), m = 5.
y = mx + b = 2,
5(2) + b = 2,
b = 12,
y = 5x + 12.
3. 5x + 3 = 13,
5x = 13  3 = 10,
X = 2.
4. You need a sign between 6x and 3x.
5. [x3] > 8,
+(x3) > 8,
+(x3)> 8,
x3 > 8,
x > 8+3,
X > 11.
(x3) > 8,
x + 3 > 8,
x > 8  3,
x > 5,
X < 5.
Solution set: X > 11, and X < 5.
6. z=2, 6z5 = 6*(2) 5 = 125 = 17.
z = 2, 6z = 6*2 = 12.
7. Answer incorrect.
Use same procedure as #1.
8.
9. 5x 4 = 41,
5x = 41 + 4 = 45,
X = 9.
10. Y = (1/2)x. or Y = x/2.
11. 2x + 5 > 1,
2x > 1 5.
2x > 6,
X > 3.
