Answer:
The answer is 3/7
Step-by-step explanation:
Find the GCD of both 35 and 15. This is 5.
Then, divide the numerator and denominator by the GCD.
15 ÷ 5/ 35 ÷ 5
This equals 3/7.
Solve simultaneously.
4x - y = 8
6x + y = 2
Multiply top equation by 6, and bottom equation by 4, to eliminate x, so that we can find y.
~
24x - 6y = 48
24x - 4y = 8
Subtract top from bottom to form one equation.
~
-2y = 40
Therefore y is 20.
Put y back in to an equation, such as 4x - y = 8.
~
4x - 20 = 8
4x = 28
x = 7
Answer:
reduce 10 qauts of 50%
Step-by-step explanation:
In order from left to right:
D, C, A, B
Answer:
Neither
Step-by-step explanation:
5 x -10 = -50
4 x 9 = 36
-50 + 36 = -14 and therefore can not be orthogonal
sqrt(25+16)=sqrt(41)
sqrt(100+81)=sqrt(181)
sqrt(41) x sqrt(181) is not equal to -14 so therefore it is not parallel
So the answer is then neither
