Slope is calculate using the following equation:
slope = (y2-y1) / (x2-x1)
since the slope is undefined, therefore, the denominator is equal to zero, which means that x2 = x1.
Based on this, the only curves with undefined slopes are the curves with equation: x = constant
Therefore, <span>equation of a line passing through a point (5,-3) with and undefined slope is x = 5</span>
Answer:
3
Step-by-step explanation:
For a graph not to be a function, it means that a particular value of x has more than one corresponding value of y. Looking at the graph, at the point where x = 3 on the horizontal axis, there are so many value of y. Plus, the graph below is not a function at x = 3
The correct option is 3
Answer:
Explanation:
8c + 3 = −40c − 10
[ Step 1: Add 40c to both sides ]
8c + 3 + 40c = −40c − 10 + 40c
48c + 3 = −10
[ Step 2: Subtract 3 from both sides ]
48c + 3 − 3 = −10 − 3
48c = −13
[ Step 3: Divide both sides by 48 ]
48c / 48 = −13 / 48
C = -13 / 48 or -0.27083333333
