Answer:

3. -2(3m + 9) = -6m - 11

4. -6(z-1) = -6z + 6

5. -(m +1) = -m - 1

6. -(x+4) = x = 4

7. b(a- 6) = ab - 6b

8. 7a(3b -2c + 4) = 21ab - 14ac +28a

9. 1/2(8x + 2) = 4x + 1

10. 2/3(1/4x -6) = 1/6x - 4

I think your teacher's just asking for the multiplied out version, so there's no work to do

3. -2(3m + 9) = -6m - 11

4. -6(z-1) = -6z + 6

5. -(m +1) = -m - 1

6. -(x+4) = x = 4

7. b(a- 6) = ab - 6b

8. 7a(3b -2c + 4) = 21ab - 14ac +28a

9. 1/2(8x + 2) = 4x + 1

10. 2/3(1/4x -6) = 1/6x - 4

0/1 Solve the equation by completing the square. Round your answer to the nearest hundredth, if necessary x^2+18x=7

11111nata11111 [884]

Answer:

The solution to the equation is x = 0.38 or -18.38

Step-by-step explanation:

x^2+18x=7 can be properly written as

$x^{2} +18x =7$

To solve by completing the square, divide the coefficient of x by 2, square and then add to both sides

i.e 18/2 = 9

Then add 9² to both sides of the equation

$x^{2} +18x + 9^{2} = 7 + 9^{2}$

This becomes

$(x+9)^{2} = 7 + 81$

$(x+9)^{2} = 88$

$x+9 = \pm \sqrt{88}$

$x = -9 \pm\sqrt{88}$

$x = -9 \pm 9.38$

∴ $x = -9+9.38 or -9-9.38$

$x = 0.38 or -18.38$

Hence, x = 0.38 or -18.38

What is the slope of the line represented by the equation y = -2/3 -5x?<br>

lana [24]

-5

Make the equation into slope-intercept form, which is y = mx + b, where m is the slope, and b is the y-intercept.

In the equation y = -5x - 2/3, the slope is -5 and the y-intercept is -2/3.
