Thirty-two thousand six hundred fifty-one
Answer:
They are proportional
Step-by-step explanation:
Y/X represents coordinates Y being rise X being run. So Y/X is equal to rise/run. If there was a coordinate grid, if the two points created a straight line that slant to the right I would be proportional. Since all I see is rise/run= 5 they are proportional. 5 represents the slope.
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. ... Slope is calculated by finding the ratio of the "vertical change" to the "horizontal change" between (any) two distinct points on a line.
(Got it from google lol hope it helped!)
Answer:
Step-by-step explanation:
We have the function:
And we want to use the difference quotient:
To find the slope function.
So, let's substitute for our function. This yields:
Let's square. Use the perfect square trinomial pattern. This yields:
Distribute:
Distribute the right:
Combine like terms:
The first three terms will cancel. This leaves us with:
We can factor out a Δx from the numerator:
The Δx will cancel. So, our slope function is:
And we're done!
X+y=20
xy=99
Let a+b be denoted a,b
20 = 1,19 2,18 3,17 4,16 5,15, 6,14 7,13 8,12 (9,11) ..Stop
99=3^2*11
Thus the ages are 11 and 9 with a difference of 2.
