Answer:
<em>m=-1/2</em>
Step-by-step explanation:
The equation is in y=mx+b form. M is the slope. In this equation, -1/2 is m.
Therefore the slope is -1/2.
Let number of miles be x
<span>when is </span>
<span>.5x + 25 = .25x + 30 </span>
<span>times 4 </span>
<span>2x + 100 = x + 120 </span>
<span>x = 20 </span>
Y-intercept is (0,2) bc that’s where the line hits the y-axis.(the up and down line)
The slope is 1/2 because you go up one over two coordinate to get to the next dot.
The equation is y=Mx+b
M is the slope
X is the amount of times you use the slope
B is the initial value
Y=1/2x+2
Given:
Diagram of a circle and its two secant from an exterior point.
To find:
The value of x.
Solution:
We know that, If two secant are on a circle from an exterior point, then the products of measure of secants and measure of external segments of secants are equal.
Using the above property, we get




Splitting the middle term, we get



Using zero product property, we get
and 
and 
Side cannot be negative.
Therefore, the only possible value of x is 1.
