Answer:
y = -1/3
x = 0
Step-by-step explanation:
3x-6y = 2 then 3x = 2+6y, x=(2+6y)/3
4x+3y = -1
substitute for x
4(2/3+2y)-6y = 2
8/3+8y-6y = 2
reduce
2y = 2-8/3
2y = -2/3
divide both sides by 2
y = -1/3
4x+3(-1/3) = -1
4x = 0
x = 0
Answer:
2: 67
3:67
4: 113
Step-by-step explanation:
Answer:
The answer is B. 14.7%.
Step-by-step explanation:
Given:
Estimated time need to complete project
.
Actually time needed
=
h.
Difference between the time
= 
.
So, the percentage error is
.
Therefore, the answer is B. 14.7%.
1. is D) 4/3 To find the slope we will insert the numbers into this formula: y2 - y2 / x2 - x1, so... 1 + 3/ 1 + 2 (the negatives canceled each other out)
now simplify and it becomes 4/3
so ur answer to 1. is D) 4/3
2. Plot this one...it rly helps...then use the slope to find the point ur looking 4, the answer is C) -2
3. The answer is B) -2
Hope that helps u out!! :)
