Answer:
x = y^2 – 7
Step-by-step explanation:
The first step in finding the inverse of y = f(x) can be to write the equation x = f(y). The equation shown above is such an equation.
Answer:
equation: 2.75 g/cm^3 * 1 m *3 m* (100 cm/1 m)^2 *4 cm * (1 kg/1000 g)
Step-by-step explanation:
countertop mass, m =?
density, ρ = 2.75 g/cm^3
wide, w = 1 m
long, l = 3 m
thick, t = 4 cm
countertop volume, V = w*l*t = 1 m *3 m*4 cm* (100 cm/1 m)^2
Isolating mass from density definition gives
ρ = m/V
m = ρ*V
m = 2.75 g/cm^3 * 1 m *3 m* (100 cm/1 m)^2 *4 cm * (1 kg/1000 g)

Answer: The measure of the first angle is 74.4 degrees.
Step-by-step explanation:
Let x be measure of the first angle and y be the measure of the second angle .
As per given , we have

Substitute the value of x from (2) in equation (1), we get

Put y= 15.6 in (2), we get

That means The measure of the first angle is 74.4 degrees.
Correct answer : The measure of the first angle is 74.4 degrees.
