Answer:
x = ±
Step-by-step explanation:
We have been given the quadratic equation;

The first step is to subtract 50 from both sides of the equation;


Multiplying both sides by -1 yields;

The final step is to obtain square roots on both sides;

Therefore, x = ±
Answer: undefined
Step-by-step explanation:
The answer is undefined because when you plug in the points in the formula
y2-y1/ x2-x1 the denominator is 0 which makes it undefined. Also when you put it into a graphing calculator it will say that its undefined.
Answer:
The graph is positive and would have a y intercept of 1 and a slope of 2 which means choose a point on the graph and add 2 to the y and 1 to the x and you should be at the next point on the line.
Step-by-step explanation:
y=mx+b
f(x)=y
m = slope
b = y intercept
First you need to make it look like y=mx+b
y = 2x - 1 + 2
y = 2x + 1
Now we can say,
m = 2
b = 1
or,
Slope = 
y intercept = 1
Slope (m) = 
So the numerator is the value your are going to go up or down along the graph and the denominator is the value of how far you are going to go left or right along the graph. If the slope is positive then the graph is inclining. If the slope is negative, the graph is declining.
