The constant term is 15, because x^2 + 8x+ 15 factors to (x + 3)(x +5). Thus, by the zero rule x = -3 and -5.
Answer:
Step-by-step explanation:
If y varies directly with x, it is:
Constant is -2, it means k= -2
Answer:
1
Step-by-step explanation:
The y-coordinate is 4, so we count 4 units up the y-axis from the x-axis. You can also look at it as counting 4 units up from the origin. Then, we look at graph C. When y=4, when we're 4 units above the x-axis, x=1 since the point on the line falls 1 unit to the right of the y-axis.
