Answer:
There are no true solutions to the equation.
Step-by-step explanation:
<u><em>The correct equation is</em></u>
Solve for y
squared both sides
<em>Verify</em>
substitute the value of y in the original expression
----> is not true
therefore
There are no true solutions to the equation.

Answer:
Step-by-step explanation:
A company manufactures two types of fishing rods, standard and folding. The cost of manufacturing 2 folding rods and 1 standard is $35. If 5 standard and 7 folding rods were manufactured, the cost would be $145. How much does it cost to manufacture each type of rod.
let S = standar rod
F= folding rod
2F + S =35
2F + S -2F =35 - 2F
or S = 35-2F
7F + 5S =145
7F + 5S -7F =145 -7F
or 5S =145-7F
Since S=35-2F
5S = 5X (35-2F)
5S = 175 -10F
which equals 145-7F
175-10F = 145-7F
175-10F +10F = 145 -7F + 10F
175 = 145 +3F
175 -145 =145 -145 + 3F
30 = 3F
F = 10
but S =35 - 2F
so S = 35 -2X10
S = 35-20 =15
check:
if F = 10 and S = 15
then 5S +7F should equal 145
5X15 + 7X10 = 75 + 10 =145
so F=10, S=15
You need 72.26 inches to frame the mirror
Step-by-step explanation:
Lets revise the rules of a circle
- Its area is A = πr², where r is the length of its radius
- Its circumference is C = 2πr
A circular mirror has a radius of 11.5 inches
We need to frame it
∵ The frame of the mirror is surrounded its circumference
∵ The length of the frame = the circumference of the mirror
∵ C = 2πr
∵ r = 11.5 inches
∴ C = 2π(11.5)
∴ C = 72.26 inches
You need 72.26 inches to frame the mirror
