Answer:
D: Positive numbers are greater than or equal to zero. For every positive number, there is a negative number that is its opposite.
Step-by-step explanation:
If x+y=5, let y = 0 to find the x-intercept: x=5. The x-int. is at (5,0).
Let x = 0 to find the y-int: y=5. The y-int is (0,5).
Plot (5,0) and (0,5), and then draw a straight line thru both points.
If x+y=5, solving for y results in y = -1x + 5
Comparing this to y = mx + b, m=-1 and b= 5. Again, the y-int. is (0,5).
Answer:
1. y = 4x - 4
2. y = x + 2
3. y = -2x - 4
4. y = -x + 2
Step-by-step explanation:
Slope-intercept form is y = mx+b. As we know, m is the slope and b is the y-intercept. We need to find the slope and y-intercept and put them in the equation. Slope is rise over run, so we just count up then over until we get to an intersection. For the y-intercept, we look where the line crosses the y-axis.
Answer:
71
Step-by-step explanation:
Here is an excel that explains how to get the result.
The answer is NO,because if you put 3 CDs or less in each shelf you only can put 15 (3*5=15), the same reason for both questions.
