Hello there! the answer would be x = 3/4.
You are given the two equations: 4x - 2y = 8 and y = 1/2x + 2. You are asked to solve via substitution. To do this, substitute the value of y in the second given equation into the first given equation, and solve using PEMDAS.
4x - 2(1/2x + 2) = 8 - Start by distributing 2 into (1/2x + 2).
4x - 1x + 4 = 8 - Combine like terms.
3x + 4 = 8 - Subtract 4 from both sides.
3x = 4 - divide both sides by 3.
x = 3/4. This is your final answer.
I hope this was helpful, have a great day! :)

You take 53.16 and divide by 8.86. Or you can do is add 8.86 over and over until you get 53.16.
The reason is because it takes 8.86 mins to send a report. 6 times 8.86 equals 53.16
Answer:
1) Congruent
2) Alternate exterior angles
3) 15x = 12x + 15
4) x = 5
Hope this helps!
Answer:
Positive correlation
5 hours yield a score of 76
41 is the test score for no hours of study
Step-by-step explanation:
There is a positive correlation because the more hours spent on homework the better the test score generally it.
Use the function y=7x+41 by substituting x=5 and simplifying to predict the test score.
y=7(5)+41
y=35+41
y=76
The number 41 is the y-intercept and starting value. This means with 0 hours of study you are likely to score a 41 on the test.
