Start off with X. If X=5+Y and X+Y=3Y-3 set up a system of equations problem to solve. You can plug in 5+Y for X in the second equation. 5+Y+Y=3Y-3. Combine like terms and 5+2Y=3Y-3.
Isolate the variable and you get Y=8. The smaller number is 8 and the larger number is 13.
Lines are parallel if and only if there slopes are the same
the slope will be m in the equation y=mx+b notice that the coefficient of y is 1
a)y=3/5x+1
b)5y=3x-2---> divide the whole equation by 5-->y=3/5-(2/5)
c)10x-6y=-4-->solving for y--->-6y=-4-10x--->dividing by -6--->y=(-10/-6)x-(4/-6)
so a and b are parallel
for the second question
a)4x-3y=2---->-3y=2-4x---->y=(2/-3)+(4/3)x
b)3x+4y=-1--->4y=-1-3x---->y=(-1/4)-(3/4)x
c)4y-3x=20--->4y=20+3x--->y=5+(3/4)x
so no parallel lines in the second question
This is the answer
48, 72 84 is the right order that this go in
Answer:
I think it would be 98
Step-by-step explanation:
Just either add or divide.
If one is 5"x3", and the other having the same orientation is 3"x?, then
by similar figures,
5/3=3/x
cross multiply,
5x=3*3
x=9/5=1.8"
With the original figure, it is possible to validate the above answer.
