Answer:
y = 2/7x + 7
Step-by-step explanation:
We start off by putting the original equation into slope-intercept form. Subtract 7x from both sides, then divide both sides by -2. Your new equation should be y = -7/2x - 8. It's important to know that when two lines are perpendicular, their slopes (m) are opposite reciprocals of each other. So -7/2 becomes 2/7. The first part of your final equation is y = 2/7x + b.
Next, we need to find the y intercept (b). You need to plug the x and y values from the given coordinate point (-7,5) into your final equation. You should end up with: 5 = 2/7(-7) + b. Then, solve for b.
5 = -14/7 + b
5 = -2 + b
7 = b
Finally, plug the b value into your final equation and you will have your answer.
Answer:
mean = 148
median = 150.5
range = 60
Step-by-step explanation:
mean = sum divided by number of data
median = (n+1)/2
range = highest data-lowest data
Answer:
Step-by-step explanation:
l = 4m = 400 cm
w = 3m = 300 cm
Volume = 720000 cubic cm = 720000
length * width * height = 720000
400 * 300 * height = 720000
height = 720000 / 400 * 300 = 72/12 = 6 cm
