The mean can be found by adding the two numbers and dividing by 2
let the second number be y
(x + y)/2 = 1/2x + 1
solve for y
multiply each side by 2
x + y = 2(1/2x + 1)
distribute
x + y = x + 2
subtract x on both sides
y = 2
ANSWER: the second number is 2
Answer:
Step-by-step explanation:
(12 - 2)/(2 - 7) = 10/-5 = -2
y - 12 = -2(x - 2)
y - 12 = -2x + 2
y = -2x + 14
24/5 = (20 + 4)/5 = 20/5 + 4/5 = 4 + 4/5
= 4 4/5
A. time and distance
1.distance depends on time
2. independent. time
dependent. distance
b. y=50x
input number put in for x
output the y value after its solved.
2a. y=50(6)
y=300
2b. no it will travel 25 miles less because if you plug 4 in for x it equals 200
hope this helps
