Answer:
y=1x+2
Step-by-step explanation:
im not sure if this is correct but i tried my best
Like when adding/subtracting fractions at any other time, you need a common denominator, in this case (x-1)(x+1)=x^2-1 so:
(2(x+1)+3(x-1))/(x^2-1)=4 multiply both sides by (x^2-1)
2x+2+3x-3=4x^2-4 combine like terms on left
5x-1=4x^2-4 subtract (5x-1) from both sides
4x^2-5x-3=0 using the quadratic formula for expediency
x=(5±√73)/8
x≈-0.443 and 1.693
An obtuse triangle...hope that helps
I can help with the first problem.
7x to the 4th power is 2401x
5x to the 4th power is 625x
2401x - 625x = 1776x
Hope this helped a bit.
Answer:
A stone is thrown straight up from the edge of a roof, 750 feet above the ground at a speed of 14 feet per second. A) Remembering that the acceleration due to gravity is -32 feet per second squared, how high is the stone 2 seconds later? B) At what time does the stone hit the ground? C) What is the velocity of the stone when it hits the ground?
