If you want to solve that put it in the formula to find the slope
M=
Y1-y2
---------
X1-x2
And plug that into slope int form with one of the points to find the y int/ b value and then your have ur equ
Answer:
a = 20; b = 2√101
Step-by-step explanation:
The triangle at upper left and the one at lower right are similar. Ratios of corresponding sides are equal, so ...
200/a = a/2
400 = a^2
√400 = 20 = a
Then, by the Pythagorean theorem, the value of b can be found:
b = √(a^2 + 2^2) = √(400 +4) = √4·√101
b = 2√101
First you bring the x to one side so u subtract 4x from 7x and you get the new equation as -9=3x+12 then you just solve and you get x is equal to -7
Answer:
At these rates Sydney read 10 pages per hour more than Zander.
Step-by-step explanation:
Zander read
pages in
of an hour.
Therefore, pages read by Zander in 1 hour = 
= 
= 
= 55 pages per hour
Sydney read
pages in
of an hours.
Pages read by Sydney in 1 hour = 
= 
= 65 pages per hour
Therefore, number of pages read more by Sydney as compared to Zander,
= 65 - 55
= 10 pages per hour
At these rates Sydney read 10 pages per hour more than Zander.
