X^2+5x-104=0 solve quadratic equations

Answers

Answer 1

Answer: $x^2+5x-104=0\n\na=1;\ b=5;\ c=-104\n\n\Delta=b^2-4ac;\ if\ \Delta > 0\ then\ x_1=(-b-\sqrt\Delta)/(2a);\ x_2=(-b+\sqrt\Delta)/(2a)\n\n\Delta=5^2-4\cdot1\cdot(-104)=25+416=441;\ \sqrt\Delta=√(441)=21\n\nx_1=(-5-21)/(2\cdot1)=(-26)/(2)=-13;\ x_2=(-5+21)/(2\cdot1)=(16)/(2)=8\n\nAnswer:x=-13\ or\ x=8.$

Answer 2

Answer: You first have to factor and get (x-8)(x+13)=o and set them equal to zero x-8=0 x=8 x+13=0 x=-13

If |x| > 5 then x>5 true or false?

Answers

Final answer:

If |x| > 5, then x > 5 is true.

Explanation:

If the absolute value of x, denoted |x|, is greater than 5, then x must be either greater than 5 or less than -5. This is because the absolute value of a number is its distance from zero on the number line, so any number that is more than 5 units away from zero will be greater than 5 or less than -5.

In this case, we are looking for x to be greater than 5, so the statement x > 5 is true.

Answer:

Step-by-step explanation:

5x-22 and 88 are the same angle so 5x-22=88.

You simply solve from there.

5x=88+22

5x=110

x=110÷5

x=22

Alex played basketball 20 minutes longer on Tuesday than she did on Monday. She played for a total of 110 minutes for both days. Which equation can be used to find the number of minutes Alex played on Monday?

Answers

Answer: The equation to find the number of minutes Alex played on Monday is x+(x+20) = 110 minutes

Step-by-step explanation:

let the time played by Alex on Monday be represented as x

and the time played by Alex on Tuesday be represented as x+20

Such that the expression to find out the minutes Alex played on Monday given that the total time spent on both days = 110 minutes

Monday +Tuesday = 110 minutes

x+(x+20) = 110 minutes

Solving

x+(x+20) = 110 minutes

2x+20= 110 minutes

2x = 110-20

2x =90

x=90/2=45

x= Amount of time played on Monday =45minutes

x+20 Amount of time played on Tuesday =45 +20= 65 minutes

Write a formula that will help them decide how much each friend will have to pay.Let's let
w = price per mile
x = number of miles traveled
y = number of friends in the cab
z = cost for each friend

Answers

Okay so since we have all the variables, we can go ahead and make our formula. So our equation would look like z = (w/x) divided by y . This is because z would be the sum of the x miles divided by the cost of each mile (w). And then we would divide what we got in the parenthesis by y (friends).
