Describe how the graphs of y=x and y=x-15 related

Sholpan [36]

They have the same slope
in y=mx+b form
m=slope
b=y-intercept
the equations are
y=1x+0 and y=1x-15
the slopes are the same, the y intercepts are the ones that changed
since they have the same slope, they are paralel to each other

What percent of 29.5 is 10.03

Alexxandr [17]

So if we take 29.5 to be the 100%, what is 10.03 in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
29.5&100\\
10.03&p
\end{array}\implies \cfrac{29.5}{10.03}=\cfrac{100}{p}\implies p=\cfrac{10.03\cdot 100}{29.5}$

The measure of an inscribed circle of an angle is the measure of the intercepted arc

Andre45 [30]

Answer:

(the statement does not appear to be true)

Step-by-step explanation:

I don't think the statement is true, but you CAN compute the intercepted arc from the angle.

Note that BFDG is a convex quadrilateral, so its angles sum to 360. Since we know the inscribed circle touches the angle tangentially, angles BFD and BGD are both right angles, with a measure of 90 degrees.

Therefore, adding the angles together, we have:

alpha + 90 + 90 + <FDG = 360

Therefore, <FDG, the inscribed angle, is 180-alpha (ie, supplementary to alpha)
