What is the equation for the line that passes through the (-2,2) and has a slope of 5?

Answer-

Y=5x + 2

Y=5x +12

Y=5x -2

None of these ¨C I believe this is the answer

Find the value of x^3+¡¼2x¡½^2-3 when x =3.

Answer- 42

Solve 5x+3=13 for x.

Answer-2

Compare the quantity in Column A with the quantity in Column B.

Column A Column B

The solution of The solution of

2(x-3) = 6x 3x + 2 + 5x + 6

Answer-The quantity of Column B is greater

Solve for x in |x-3| >8.

Answer-

Compare the quantity in Column A with the quantity in Column B.

Column A Column B

6z-5 if z=-2 -6z ¨C 5 if z = 2

Answer-The quantities are equal

What is the equation for the line that passes through the point (5, 5) and a slope of 2?

Answer-y=2x+ 2

Evaluate ¡¼2y¡½^(2 ) (x+y) when x =8 and y+3

Answer-198

Solve 5x-4 = 41 for x.

Answer-9

What is the equation for the line that passes through the point (0, 0) and has a slope of -1/2?

Answer-y=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

**Henry**, Sunday, August 7, 2011 at 5:16pm1. 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. [x-3] > 8,

+-(x-3) > 8,

+(x-3)> 8,

x-3 > 8,

x > 8+3,

X > 11.

-(x-3) > 8,

-x + 3 > 8,

-x > 8 - 3,

-x > 5,

X < -5.

Solution set: X > 11, and X < -5.

6. z=-2, 6z-5 = 6*(-2) -5 = -12-5 = 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.
