Answer: -14
Remove parenthesis to -1-4+(-9)
When there is a “+” in front of an expression in parenthesis, the expression remains the same, so;
-1-4-9 calculate the sum of the negative numbers
-1-4= -5, -5-9= -14

The order of magnitude for total attended for a high school football team that averages 1,000 fans for each of its 5 home games
Tatiana [17]

The order of magnitude for total attended for a high school football team is 3

<h3>How to determine the order of magnitude?</h3>

The given parameters are:

Average number of fan = 1000

Number of home games = 5

The total number of fans in the 5 games is:

Total number of fans = Average number of fan * Number of home games

Substitute known values in the above equation

Total number of fans = 1000 * 5

Express 1000 as 10^3

Total number of fans = 10^3 * 5

Rewrite the equation as:

Total number of fans = 5 * 10^3

The power of 10 represents the order of magnitude

Since the power of 10 is 3, the order of magnitude is 3

Hence, the order of magnitude for total attended for a high school football team that averages 1,000 fans for each of its 5 home games is 3

Answer:

x=<u>+</u>\frac{\sqrt{4y-7}-1 }{2}

Step-by-step explanation:

Quadratic function =( -b<u>+</u>\sqrt{b^2+4ac}  )/2a

x^2+x+2-y=0

x=-1<u>+</u>\sqrt{1^2-4(2-y)} /2

x=-1<u>+</u>\sqrt{4y-7} /2

x=<u>+</u> \frac{\sqrt{4y-7}-1 }{2}

Pretty sure this is right. Would appreciate a brainliest
