Answer:
(1, 1 )
Step-by-step explanation:
Given the 2 equations
y = - 5x + 6 → (1)
y = 3x - 2 → (2)
Since both equations express y in terms of x, equate the right sides
3x - 2 = - 5x + 6 ( add 5x to both sides )
8x - 2 = 6 ( add 2 to both sides )
8x = 8 ( divide both sides by 8 )
x = 1
Substitute x = 1 into either of the 2 equations for corresponding value of y
Substituting x = 1 in (2)
y = 3(1) - 2 = 3 - 2 = 1
Solution is (1, 1 )

Question 4: true?
question 5: true
Its C. Because 96 x 70 equals 6,720 and 80 x 80 x 80 x 80 equals 4,096,0000.
So, the question is, whether using the ratio of 1.35261 will give the same results as using the ration of 1.35 if the final answer has to be rounded to the hundreth places anyway.
let's try for 10 euros:
10*1.35=13.5 dollars
10*1.35261=13.5261, rounded to 100th: 13.5 the same!!!
Let's try for 250 dollars:
250*1.35=337.5 dollars
250*1.35261=338.1525, rounded to 100th: 338.12
so, if they use the exact exchange rate, they get more dollars!
In fact the more they exchange, the bigger the difference will be ,as for each dollar exchanged the difference is 0.00261.
So they better use the exact exchange rate!
