Answer:
x=3
Step-by-step explanation:
5x+9 = 24
Subtract 9 from each side
5x+9-9 = 24-9
5x = 15
Divide each side by 5
5x/5 = 15/5
x =3
Answer:
I believe it is B.
Step-by-step explanation:
y=mx+b
y=mx+3
y= -1/2x+3
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>
