Multiply all terms by x and cancel
xx+-15=2x
x^2-15=2x simplify both sides
x^2-15-2x=2x-2x subtract 2x from both sides
x^2-2x-15=0
(x+3)(x-5)=0 factor left side of equation
x+3=0 or x-5=0 set factors equal to 0
x=-3 or x=5
hope this helps!
Answer:
the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis
You subtract 8 from both sides.
Answer:
Step-by-step explanation: Alright adding fractions here we go.
3 3/5 + 2 1/4
First add up the whole numbers. 3+2=5
Then adding the mix numbers, what you need to do is find a common demoninator. What do 5 and 4 both go into? Well 20, so we multiply each demoinator to get 20.
3/5+1/4
12/20 + 5/20
17/20
Answer is 5 17/20.
22.8 kg because you just multiply 7.6x3
