Answer:
Step-by-step explanation:
We'll call the 2 numbers x and y. Starting with the last part of that first sentence "one number is 10 times the other number" can be written, in algebraic form:
y = 10x
Now on to the first statement about the numbers: "twice their sum" is 2(x + y) and "equals their product" is = xy. Putting that all together:
2(x + y) = xy and we know that y = 10x so
2(x + 10x) = x(10x) and
and
and
x(10x - 22) = 0 so
x = 0 or 10x - 22 = 0 which makes
x equal to
So x = 2.2 and y = 22.

Simplify
Cross Multiply
A clock is a circle which is 360 degrees.
There are 12 hours -----> 360/12 = 30 degrees.
Going clockwise, add 30 degrees for every hour the hour hand is at.
There are 60 minutes -----> 360/60 = 6 degrees.
Add 6 degrees for every minute the minute hand is at.
Find position of both hour hand and minute hand, then take the difference.
Time is 5:15.
Hour hand is at 5 plus 15/60 or 5.25.
Multiply by 30. 30*5.25 = 157.5
Minute hand is at 15.
Multiply by 6. 15*6 = 90
157.5 - 90 = 67.5 degrees.
Answer:
y =
Step-by-step explanation:
Use the points (9, 5) and (6, 1) to identify the slope of the graph
=
m =
m =
m =
The y-intercept is -7 because -7 touches y axis causing it to be the y-intercept
