Answer:
n = -6 or n = 4.
Step-by-step explanation:
-3 | -8n – 8 | = -120
Divide both sides by -3:
| -8n – 8 | = 40
This gives us 2 equations because the expression in the absolute signs can be positive or negative:
-8n - 8 = 40
so -8n = 48
n = -6.
and
-8n - 8 = -40
-8n = -32
n = 4.
Answer:
M= the slope. ( it would be the first one)
Step-by-step explanation:
In the equation y = mx + b for a straight line, the number m is called the slope of the line. Let x = 0, then y = m • 0 + b, so y = b. The number b is the coordinate on the y-axis where the graph crosses the y-axis. What is the coordinate on the y-axis where the graph of y = 2x + 3 crosses y-axis?
Answer:
38km
Step-by-step explanation:
c^2-b^2=a^2
42^2-18^2= sqrt 1440

Answer:
f⁻¹(x) = x+2 / 3
Step-by-step explanation:
Given function is:
f(x) = 3x-2
We have to find the inverse of the given function.
Put y = f(x) in given function, we have
y =3x-2
Adding 2 to both sides of the above equation we have
y+2 = 3x-2+2
y+2 = 3x
Dividing by 3 to both sides of the above equation, we have
y+2 / 3 = 3x / 3
y+2 / 3 = x
Put x = f⁻¹(y) in the above equation we have
y+2 / 3 = f⁻¹(y)
Swapping equation we have
f⁻¹(y) = y+2 / 3
Replace y with x we have
f⁻¹(x) = x+2 / 3 which is the answer.
