The equation for a line is y=mx+b
m is the slope, so when a line is perpendicular to another line is has a slope which is an opposite reciprocal, so change the -1/2 (the slope of the other line) to 2/1 or just 2
so m=2
now you need to plug in the point they give you for x and y
y=mx+b
4=2(4) + b
simplify
4=8 + b
subtract 8 over
-4 = b
now that you know that slope (m) and the y-intercept (b) you can plug those two numbers into the original equation for the answer
y= 2x -4
Surface area of bin:
A = 2(pi)rh + 2(pi)r^2
Assuming you use 3.14 for pi:
A = 2(3.14)(9)(30) + 2(3.14)(81)
A = 2204.28ft^2
Answer:
B
Step-by-step explanation:
oranges weigh 0.5 and grapefruits weigh 1.5
Answer: 247
Explanation:
When dealing with composite functions, we start with the right hand function first then apply our way to the left hand side.
1) First equate g(2)
2) Equate the function f of your answer you found in g(2)
1) 7(2) - 6
2) 14 - 6
3) 8
4) f(8) = 5(8)^2 - 10(8) + 7
5) f(8) = 320 - 80 + 7
6) f(8) = 247
Hope this helps, brainliest would be appreciated :)
Answer:
Answer# 1: A. 26
Answer# 2: A. 25
<h3><u>
Step-by-step explanation:</u></h3>
1. What is m + 5n where m = 1 and n = 5?
Substitute 1 for "m" and 5 for "n":
Multiply 5*5 =25
Add :
____________________
2. What is 5m + 5n where m = 10 and n = -5?
Substitute 10 for "m" and -5 for "n".
Multiply 5 * 10= 50
Multiply 5 * -5 = -25
Subtract:
