ERROR ANALYSIS In Exercises 39 and 40, describe and
expeople1 [14]

Answer:

39. r = 13.4

40. m = 12

Step-by-step explanation:

39. Given the equation, -0.8 + r = 12.6, to solve for r, the following are the correct steps to take to arrive at the solution:

-0.8 + r = 12.6 (given)

Add 0.8 to both sides of the equation (addition property of equality)

-0.8 + r + 0.8 = 12.6 + 0.8 (this is where the error occurred.)

r = 13.4

40. The correct steps to take in solving the equation, -\frac{m}{3} = -4 is as follows:

-\frac{m}{3} = -4 (given)

Multiply both sides by 3 (multiplication property of equality)

3*-\frac{m}{3} = 3*(-4)

-m = -12 (this is where the error occurred. This is what we should have at this line/step)

m = 12 (dividing both sides by -1)

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!! I CANNOT RETAKE THIS!!
cupoosta [38]

x =  \frac{ - b \pm \sqrt{ {b}^{2}  - 4ac} }{2a}  \\  \\ x =  \frac{8 \pm \sqrt{ {8}^{2} - 4 \times 2 \times 5 } }{2 \times 2}

x =  \frac{8 \pm \sqrt{24} }{4}  \\  \\ x =  \frac{8 \pm2 \sqrt{6} }{4}

x = 2 \pm  \frac{ \sqrt{6} }{2}  \\  \\ x = 2  \pm  \sqrt{1.5}  \\  \\ x = 2 +  \sqrt{1.5}  \:  \: and \:  \:  \: 2 -  \sqrt{1.5}
