Answer:
3
Step-by-step explanation:
For f(x) = x^3 -2x^2 -7x +5 and x=1/(2-√3), we have ...
f(x) = ((x -2)x -7)x +5
and ...
x = 1/(2-√3) = (2+√3)/(2^2 -3) = 2+√3
Then ...
f(2+√3) = ((2 +√3 -2)(2 +√3) -7)(2 +√3) +5
= (3+2√3 -7)(2+√3) +5
= 2(√3 -2)(√3 +2) +5 = 2(3 -4) +5 = -2 +5
f(1/(2 -√3)) = 3
_____
If you really mean x = (1/2) -√3, then f(x) = (42√3 -3)/8.
Division is one of the basic mathematical operations. The cost of Brand A and B is the same.
<h3>What is division?</h3>
The division is one of the most basic arithmetic operations. It is used to find the number of times a number is been added to itself.
Given to us
Brand A: 14 ounces for $44.66
Brand B: 20 ounces for $63.80
To compare the two brands we will find the cost of one ounce for each brand.
For Brand A,
The cost of 14 ounces is $44.66, therefore,

For Brand B,
The cost of 20 ounces is $63.80, therefore,

From the above two values, we can conclude that the cost of Brand A and B is the same.

Answer:
a)6x = 16
Step-by-step explanation:
<h2><u>Finding the value</u></h2>
the ratio can be solved by <u>cross multiplication :</u>
6 : 2
8 : x
6*x = 8*2
6x = 16
answer is : <u>a) 6x = 16</u>
Answer:
2600 into the account earning 1% interest
2400 into the account earning 6% interest
Step-by-step explanation:
let x= account earning 1% interest
y= account earning 6% interest
we can write
x+y=5000 (equation 1)
.01x+.06y=170 (equation 2)
mulitply equation 1 by .01
.01x+.01y=50
subtract this from equation 2
(.01x+.06y)-(.01x+.01y)= 170-50
.05y= 120
y= 2400
Plug in y= 2400 into equation 1
x+2400=5000
x=2600
