Im gona assume you mean
f(x) = 3x + 2 + 8x + 4. Add like-terms
Y = 11x + 6
0= 11x + 6
-6 = 11x
X= -6/11
Answer:
x = 7.
Step-by-step explanation:
-5x + 18 = 3x - 38
18 + 38 = 3x + 5x
56 = 8x
x = 7.
Answer:
Step-by-step explanation:
it's another one of those similar triangles
it's easier to see this one.
t /c = u / b
where
t = 7x + 3
c = 27
u = 35
b = 21
plug in the knowns
7x + 3 / 27 = 35 / 21
7x + 3 = 27 ( 35 / 21 )
7x + 3 = 9 ( 35 / 7 ) ( divided by 3 )
7x + 3 = 9 ( 5) ( 7 into 35 =5 )
7x + 3 = 45
7x = 45 - 3
7x = 42
x = 6
I checked it, the ratio is 1_2/3 :) for both, but you can check it too
Number 1 is x=8!!
2 is pretty confusing so I hope someone else can answer two as I have answered 1!
Substitute the variable terms with the coordinates and the equation is
3=1/3(5)+b
solve for b
