Answer:
A= 15 root 5 - 10 ÷ 41
Multiply (3 root 5 - 2) top and bottom. Simplify
B= - 2
Multiply (root 3 + root 5) top and bottom. Simplify
C= 6x - 3 root xy ÷ 4x - y
or
3x - 3 root xy ÷ 2x - y
(because 6 & 4 is Divisible by 2)
Multiply (2 root x - root y) top and bottom. Simplify
Root means a square root - so, replace the word root with a square root!
Hope this helps!
Answer:
15 nickels were there with Alexis
Step-by-step explanation:
Let there be x nickels
given that
The number of dimes is 5 less than twice the number of nickels.
no of dimes in terms of x = 2*number of nickels - 5 = 2x - 5
we know that
value of 1 nickel = 5 cents
then
value of x nickel = 5*x cents = 5x cents
we know that
value of 1 dime = 10 cents
then
value of 2x-5 dime = 10(2x - 5) cents = 20x - 50 cents
Total value of x nickel and 2x -5 dimes = 5x + 20x - 50 = 25x - 50
given that
Alexia has total of $3.25 in nickel and dimes thus 25x - 50 must be equal to $3.25
$1 = 100 cents
$3.25 = 3.25 * 100 cents = 325 cents
Thus,
25x - 50 = 325
25x = 325 + 50 = 375
x = 375/25 = 15
Thus, no of nickels = x = 15 answer
Function f(4) = -10 and if g(x) = 2 , x = 0.
To find f(4), we will observe the graph of f(x).
According to the graph of f(x),
when x = 4, y is -10 which means when x is 4 value of f(4) is -10.
To find the value of x when g(x) is 2, we will observe the graph of g(x).
According to the graph of g(x),
when y = 2, x is 0 which means that when x is 0, the value of g(x) is 2.
Hence, f(4) is -10 and x = 0 when g(x) = 2.

I'm not 100% sure but what I remember it's this
The answer is the first one (y = 1/2x + 1). It is asking how to graph an equation, revisit your material to learn how to do it.
