Answer:6x -6
Step-by-step explanation:
4 times x and 4 x -2 4x -8
2 times x and 2 x 1 2x +2
Answer:
Step-by-step explanation:
<u>The line with points (1,2) and (-1,-8). Work out its equation.</u>
<u>The slope is:</u>
- m = (-8 - 2)/(-1 - 1) = -10/-2 = 5
<u>To find the y intercept, substitute x and y-xoordinates of point (1,2):</u>
- 2 = 5(1) + b
- b = 2 - 5
- b = -3
<u>The line is:</u>
<u>Point (x, 17), substitute y-coordinate and solve for x</u>
- 17 = 5x - 3
- 5x = 17 + 3
- 5x = 20
- x = 20/5
- x = 4
Answer:
30
Step-by-step explanation:
62 = 2x+2
62-2 = 60
60/2 = 30
7. 335*0.2=67
8. 4.5/0.6=7.5
9. A
