Answer:
6x-21+5 = -19 Distribute
6x-16 = -19 Combine like terms
6x = -3 Add
x = -1/2 Division
Formula for slope-intercept is y = mx+b. The y-intercept is the point where the line crosses the y-axis. From there on, use the slope to graph the line. For example, if the equation is y = 5x - 2, you would want to plot (0,-2) first on the graph. Then, continue using the slope, which is 5. Slope is rise/run. In this case, you go up five, then to the right one, since there is always an invisible one if the slope is a whole number.
Hope that helped. :)
Answer:
<u>B: x < -5</u>
- 2x - 7> x + 8
-3x - 7 > 8
-3x > 15
(switch sign when dividing or multiplying by a negative on opposite sides)
x < -5
<span>y=10x-9 , y=x+18
10x-9=x+18
9x-9=18
9x=27
x=3
y=10x-9
y=10 (3)-9
y=30-9
y=21
