The simplified ratio of 15:5 is 3:1, divided both sides by 5
Answer:
probably b
Step-by-step explanation:
I think for the other 3 answers, you are trying to have the x's have exponents, making them non-linear. While since b increases by 5 when x increases by 1, it is a linear function
General rule for the reflection. r(x,y,z)= f(x,-y,z)
Results:
P: (0, - 5, 4)
Y: (-2, - 7, 4)
R: (0, - 7, 4)
A: (0, - 7, 6)
General rule for the translation: t(x,y,z) = r(x+2, y-4,z+3)
Result:
P: (0-2, -5+4 , 4-3) = (-2, -1, 1)
Y: (-2-2, - 7+4, 4-3) = (-4, -3, 1)
R: (0-2, - 7+4, 4-3) = (-2, -3, 1)
A: (0-2, - 7+4, 6-3) = (-2, -3, 3)
Answer:
The solution of the given equations are (3,2).
Step-by-step explanation:
Given equations are :
3d−e=7 ...(1)
d+e=5 ...(2)
Add equations (1) and (2) we get :
3d-e+d+e=7+5
4d = 12
d = 3
Put the value of d in equation (2).
3+e=5
e = 2
So, the value of d = 3 and e = 2. Solution of the given equations are (3,2).
