To simplify the expression (5x^2 - 21x - 20) / (5x^2 - 16x - 16), we can check if there are terms that are needed to be added or subtracted. In this case, there are none. We just check the factors of each polynomial above and below. The factored equation of the numerator is (x-5)*(x + 4/5) while that below is (x-4)* (x + 4/5). In this case, we cancel <span>(x + 4/5). Hence the answer is (x-5) / (x-4)</span>
Answer: 30%
Step-by-step explanation:
First find the difference between the old score and the new:
= 390 - 300
= 90 points
To find the percentage increase, divide the difference by the original score:
= 90 / 300
= 30%
I believe the answer is 90
Answer:
x=2
y=1.732
Step-by-step explanation:
we use the formulae.....
SOHCAHTOA
where..Cos 60°=1/x
cos60=0.5
0.5=1/1
<u>X</u><u>=</u><u>2</u>
0.8660=y/2
y= 1.732
Answer:
Step-by-step explanation:
we know that
The solution of the linear system of equations is the intersection point both graphs
using a graphing tool
we have
------> equation A
------> equation B
To find the solution equate the equation A and equation B
Solve for x
Find the value of y
------>
the solution is the point
