63 i believe..
3 divided by 2 is 1.5
1.5 times 42 is 63
B or D so sorry these ones are confusing written like this.
Gave a lovely weekend.
Answer:
f(x)⁻¹ = 3x - 18
Step-by-step explanation:
I'm going to assume that 1/3 is the coefficient of the x.
f(x) = 1/3x + 6
y = 1/3x + 6
x = 1/3y + 6
x - 6 = 1/3y
3x - 18 = y
f(x)⁻¹ = 3x - 18
y = 4x−10 ; slope m = 4
Parallel has same slope so slope of new line = 4
y = 4x + b
b = y - 4x
Passes through (1, 13)
b = 13 - 4(1)
b = 13 - 4
b = 9
Equation
y = 4x + 9
