Thank you, you’ll motivate me to work out :)
I'm pretty sure that the answer would be 7.50 because if you do ($18.99+$29.50)x2, you would get $7.50.
The first answer is : B ) <span> a perpendicular to line AB.
And i beleive the second answer is : D ) </span><span>Line segment CI and draw an arc centered at I intersecting the first arc.</span>
For the equation of the line of the form y = mx + b, m is the slope of the line and b is the y-intercept which is the value of y when x is equal to zero. The slope is the rate of change of y per change in x. "y" would represent the dependent variable which is the weight of the baby while "x" represents the independent variable which is the number of months or the age of the baby in months. We calculate the slope as follows:
slope = (11 - 9) / ( 4 - 0) = 2/4 = 0.5
at x = 0, it is said that the weight of the baby is 9 lbs so the value of b would be 9.
The equation of the line would be y = 0.5x + 9
