Answer:
42/90
Step-by-step explanation:
<u> </u>
Let x = .46
multiply both sides by 10
<u> </u>
10x = 4.66
multiply both sides by 10 again
<u> </u>
100x = 46.66
<u> </u> <u> </u>
100x - 10x = 46.66 - 4.66
90x = 42
x = 42 / 90
Can be reduced to x = 21/45
So this means W(-3x) = 3x. So it's equal to 3(-3x), which simplifies to be -9x. Whenever you have a function, it looks like f(x). f doesn't have to be the letter, it can be a, b, c, or like in this case, W. It just means the output of what W(x) is if x equals the number in the parentheses, which is -3x in this case.
Answer:
3 and - 4
Step-by-step explanation:
Calculate the gradients using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
Line A
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m = = 3
Line B
with (x₁, y₁ ) = (1, 1) and (x₂, y₂ ) = (0, 5) ← 2 points on the line
m = = = - 4
