For a segment AB, the coordinates of the middle point C are:

xc=(xa+xb)/2,

yc=(ya+yb)/2.

Now, you know points A and C. Thus we get:

xb=2×xc-xa

yb=2×yc-ya

With numerical values:

xb=2×2-(-1)=4+1=5

yb=2×3-(-5)=6+5=11

Answer: B(5, 11)

Find common denominators. 10 is the common denominator. Multiply 2 to numerator and denominator of -3/5

(-3/5)(2/2) = -6/10

x + 1/10 = -6/10

Isolate the x. Subtract 1/10 from both sides

x + 1/10 (-1/10) = -6/10 (-1/10)

x = -6/10 - 1/10

x = -7/10

-7/10 is your answer for x

hope this helps

Sean is employed as a truck driver. He drives x hours a week and is paid $21.60 per hour. Also he is paid $250 for food per week

allsm [11]

Answer:

Hours driven= 40 hours

Step-by-step explanation:

Giving the following information:

Variable income= $21.6 per hour

Fixed income= $250

Total income= $1,114

<u>To calculate the number of hours driven, we need to use the following formula:</u>

Total income= fixed income + hourly rate*number of hours

1,114 = 250 + 21.6*x

864 = 21.6x

864 / 21.6 = x

40=x

Hours driven= 40 hours
