I)
8 - 3x = 23
-3x = 15
x = -5
ii)
5x - 16 = 34
5x = 50
x = 10
iii)
2 - 5x = -3
-5x = -5
x = 1
Answer:
An insurance company polls drivers of sports cars to find their average number of tickets.
Step-by-step explanation:
It’s bias because they’re only polling people with sports cars
It would cost about $.50 because $8.15 rounds to $8.00, and 8/16 = 0.5
From my research, the original system of equations contain the following equations:
<span>2x − y = −4
3x + 5y = 59
where obtained solution is x = 3
Among the choices, it is easier to substitute </span><span>3x + 5y = 59 with one of the choices to see if they yield the same solution set. From trial-and-error, the equation that can replace the original equation is " 13x = 39 ". Among the choices, it is the 4th choice.</span>
Step-by-step explanation:
-2|5x + 3| >= 4
|5x + 3| <= -2
Since absolute value is never negative, there are no real values for x.
