Answer:
Step-by-step explanation:
First you need to get like items on the same side(put the variables on one side and the non-variables on the other). Remember anything you do on one side of the equal, you have to do on the other side, too.
5X+3=7X-1 I'm going to move the -1 first, but you don't have to as long as you keep the equation equal.
5X+3+1=7X-1+1 We know that +1-1 is zero and so is -1+1. So
5X+3+1=7X We don't need to keep that zero.
5X+4=7X Now, we want to move the 5X over.
5X-5X+4=7X-5X Simplify and get rid of the zero.
4=2X Last, we have to divide to get the 2 away from the X.
4/2=2X/2 Not everyone know that slash mean divide, :-).
2=X
Answer:
Part 1) The exact value of the arc length is
Part 2) The approximate value of the arc length is
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference of a circle is equal to

we have

substitute


step 2
Find the exact value of the arc length by a central angle of 150 degrees
Remember that the circumference of a circle subtends a central angle of 360 degrees
by proportion



step 3
Find the approximate value of the arc length
To find the approximate value, assume

substitute
<h3>

</h3>
20 cm^2
Imagine two of the as squares and then have them
To find the zeros set the equation equal to zero:
x^2 - 5x +4 = 0
Factor:
(x-4) (x-1) = 0
Now solve each set of parenthesis so that they equal zero:
(x-4) = 0, x =4
(x-1) = 0, x = 1
The zeros are 1,4
