Answer:
x = 2.4
Step-by-step explanation:
Given expression as,
2x - 4y when y = 3x - 6
Now put y in the given expression
so, 2x - 4 (3x - 6) = 0
2x - 12x + 24 = 0
10x = 24
So, x =
Hence, x = 2.4 Answer
Answer:
0.000125x
Step-by-step explanation:
Answer:
x = 65
Step-by-step explanation:
Triangle interior angle sum is 180 degrees.
2x + 25 + 25 = 180
2x = 130
x = 65
179.59 should be the answer
Answer:
1) y=-10x+50 (it's the only negative slope / going down option and it starts at x=0 y=50)
just substitute the x with a 9
y=-10*9 +50
y= -40
2) 0.5x +5 (only positive slop and starting point at x=0 is correctly 5)
we do need to substitute y this time, with 30 obviously
30 = 0.5x +5 |-5
25 = 0.5x | *2
50 = x
3) y=-2x +50 reasoning as before
substitute x with 4
y =-2*4 +50
y = -8 +50
y = 42
