Answer:
The answer to your question is: neither parallel nor perpendicular.
Step-by-step explanation:
Data
x - 7y = 10 ---(1) and 2x + 14y = 21 ---- (2)
First we need to clear y from two equations
7y = x -10 14y = -2x +21
y = x/7 - 10/7 y = -2/14 x + 21/14
y = -1/7 x + 3/2
slope = 1/7 slope = -1/7
They are neither parallel nor perpendicular, if they were parallel the slopes will be the same, if they were perpendicular they would have inverse values.
Answer:
11.64
Step-by-step explanation:
8.24+3.4=11.64
Answer:
The value of x is -4/5.
Step-by-step explanation:
First, you have to get rid of brackets, by expanding out :
2(6x+10) - 3x = 10 - (x-2)
2(6x) + 2(10) - 3x = 10 - x + 2
12x + 20 - 3x = 10 - x + 2
Next, is to bring all the x variable to one side :
12x + 20 - 3x = 10 - x + 2
12x - 3x + x = 10 + 2 - 20
10x = -8
Lastly, is to solve it by dividing 10 to both sides :
10x = -8
10x ÷ 10 = -8 ÷ 10
x = -4/5
5 parts of water plus 2 parts of vinegar.
1 part of water = (2/5) parts of vinegar
= 0.40 parts of vinegar.
So Tim mixed 0.40 parts of vinegar with each (1) part of water.
