Assume the number is x
now, we will translate the written english into equation:
seven minus 2 times the number is 7-2x
the number minus 2 is x-2
we will equate these two equations (the question says that they are equal) ans solve for x as follows:
7-2x=x-2
7+2=x+2x
9=3x
x=3
the required number is 3

Write the function for the following chart,
timurjin [86]
Dy/dx=1/2, 1/2, 1/2 etc

So this is a linear equation of the form y=mx+b where m=dy/dx=1/2 so

y=x/2 +b, now we can use any point to solve for the y-intercept, "b", I'll use (7,0)

0=7/2 +b

b=-7/2 so

y=x/2-7/2

y=(x-7)/2

Angle ADB is a right angle, which is given.

The measure of ADB is 90 degrees by definition of right angle.

The two angles are a linear pair (aka they're supplementary) by definition of linear pair (they're formed by two intersecting lines).

The measure of BDC is 90 because BDC + ADB = 180 (definition of linear pair), and ADB = 90 (given).

BDC = ADB because 90 = 90


Overall, the two triangles are congruent by SAS.
