Put the (3, 10) above (1, 15). Then take 15-10 and put 5 as the numerator, same with 1-3 and put -2 as the denominator. Slope is -5/2

Solve the equation <br> -13/4 -x= 1/2x -1
ale4655 [162]

Answer:

x = 2 or 1/4

Step-by-step explanation:

-13/4 -x= 1/2x -1

Collect like terms

-13/4+1=1/2x+x

Using LCM

(-13+4)/4=(1+2x²)/2x

9/4=(1+2x²)/2x

Cross multiply

9(2x)=4(1+2x²)

18x=4+8x²

Turn into quadratic and solve

8x²-18x+4

Using formulae method

-b±(√b²-4ac)/2a

Where a=8, b= -18 and c=4

(-(-18)±(√(-18)²-4(8)(4))/2(8)

(18±(√324-128))/16

(18±√196)/16

(18±14)/16

(18+14)/16 or (18-14)/16

32/16 or 4/16

2 or 1/4

The equation to find percent error is:
percent error=(experimental-theoretical)/theoretical *100
So, (115-82.5)/82.5=0.393939*100
39.3939%, or 39.94%

Hope this helps!!

A high school football team won 80% of the games they played. If they played 35 games, how many games did they win?
crimeas [40]

Step-by-step explanation:

formuale \\ \%wom = total \: win \:  \times 100\% \div total \: matches \: played

let x be total much won

80\% = x \times 100\% \div 35 \\  x= 35 \times 80 \div 100 \\ x = 7 \times 4 \\ x = 28

so they team had won 28 matches.

I hope the team has best players : )
