Answer:
(5,14)
Step-by-step explanation:
4x-6=2x+4 because I chose any of the y values
change of subjects ⬇️
4x-2x =4+6
2x=10
2x÷2 and 10÷2
⬆️ making x stand alone
x= 5
put x into any of the equation
y=2(5)+4
y= 10+4
y=14
Your first steps are correct. Mult. the given fraction by (1+sqrt(5)) / (1+sqrt(5)).
Result: 8(1 + sqrt(5) ) 8(1 + sqrt(5) )
------------------- = ----------------------
1 - 5 -4
Must keep that denominator (-4).
The regular price of the sofa if 66% is given off, is $680.00
What is regular price?
The regular price of the sofa is the price at which it is sold without considering the coupon of 66%, in essence, it is 100% of the original price of the sofa, in short, if 66% is given off, then the sale price is 34% of the original price
34% of regular price=$231.20
1% of regular price=231.20/34
1% of regular price=$6.80
100% of regular price=$6.80*100
100% of regular price=$680

For the given sequence we have the formula:
Sₙ = 1 + (n - 1)*2
The 50th square will have 99 shaded squares.
<h3 /><h3>
How many shaded squares are on the n-th square?</h3>
Here we have a sequence:
The first square has 1 shaded squares.
the second square has 3 shaded squares.
The third square has 5 shaded squares.
And so on.
Already you can see a pattern here, each next step we add 2 shaded squares, then we can write the formula:
Sₙ = 1 + (n - 1)*2
Where S is the number of shaded squares and n is the number of the figure.
Then the 50th square will have:
S₅₀ = 1+ (50 - 1)*2 1 + 49*2 = 99
