you can find the answer like that
Up, it is a positive number even squared
Answer:
x : y = 9 : 13
Step-by-step explanation:
Given that
3x - y : x + 2y = 2 : 5
Express the ratio in fractional form, that is
=
( cross- multiply )
5(3x - y) = 2(x + 2y) ← distribute parenthesis on both sides )
15x - 5y = 2x + 4y ( subtract 2x from both sides )
13x - 5y = 4y ( add 5y to both sides )
13x = 9y ( divide both sides by 13 )
x =
y ( divide both sides by y )
=
, that is
x : y = 9 : 13
Slope of the line;
slope=

Slope=

Slope,m =

y=mx+c
y=2x+c
Replacing for x and y using point (4,3)
3=2(4)+c
3=8+c
c=3-8
c=-5
y=2x-5
Answer:
The first step to solve the equation below is to first distribute the 2 to (x+7)
Step-by-step explanation:
2 (x+7) = -4x + 14
2x + 14 = -4x + 14
