Answer: A
golden ratio approximately equals:
(1+sqrt(5))/2=1.618
5/3=1.667
7/5=1.4
10/8=5/4=1.25
17/11=1.545
Change everything to decimal form and see what is closest.
So we can see that the photograph size of 5x3 is the best choice as it is the closest in size to the golden ratio.
Any questions at all please feel free to ask! Thank you so much!
Add the fraction to both sides of the equation.
Here we are given the inequality:

Let us check for each ordered pair that satisfies the given inequality.
1. (3,0)
LHS: y
here y is 0.
So LHS is 0.
RHS: 4x-5
plugging x as 3,
4(3)-5 = 7
0≥7
False
So (3,0) does not satisfy the inequality.
2. (1,1)
LHS: y
here y is 1.
So LHS is 1.
RHS: 4x-5
plugging x as 1,
4(1)-5 = -1
1≥-1
True
So (1,1) satisfy the inequality.
1. (3,4)
LHS: y
here y is 4.
So LHS is 4.
RHS: 4x-5
plugging x as 3,
4(3)-5 = 7
4≥7
False
So (3,4) does not satisfy the inequality.
1. (2,1)
LHS: y
here y is 1.
So LHS is 1.
RHS: 4x-5
plugging x as 2,
4(2)-5 = 3
2≥3
False
So (2,1) does not satisfy the inequality.
Answer: (1,1) is the solution of the given inequality.
These are both independent events because 1 spin does not effect the other.
P(1st spin is 3) = 1/8
P(2nd spin is 7) = 1/8
P(both) = 1/8 * 1/8 = 1/64
You didn't really ask a question, so I'm assuming you want to know if there are any solutions to BOTH equations.
Use the first equation to substitute 4x - 1 for y in the second equation:
12x = 3(4x - 1)+7
12x = 12x - 3 + 7
12x = 12x +4
0 = 4
The last equation is FALSE, indicating the system of two equations has no solution.
