Make x the subject, fully simplify please<br>will mark brainliest <br><br>7y⁴= 7y²(z-3ax)​
tekilochka [14]

Answer:

x = \dfrac{z - y^2}{3a}

Step-by-step explanation:

7y⁴ = 7y²(z - 3ax)​

Divide both sides by 7y².

y² = z - 3ax​

Add 3ax to both sides. Subtract y² from both sides.

3ax = z - y²​

Divide both sides by 3a.

x = \dfrac{z - y^2}{3a}

pychu [463]

The situation that represents the expression 2 - 5 is (a) the temperature was 2°C and has decreased by 5°C

<h3>How to determine the situation?</h3>

The expression is given as:

2 - 5

When the expression illustrates change in temperature, the interpretation can be:

An initial temperature of 2°C decreases by 5°C

Hence, the situation that represents the expression 2 - 5 is (a) the temperature was 2°C and has decreased by 5°C

You have been asked to find the inverse of f (x) = 3+Vx - 1. What would your
Paha777 [63]

Answer:

Add 1 to both sides of the equation.

Subtract 3 from both sides of the equation.

Step-by-step explanation:

The inverse of a function refers to that function that tends to undo another function.

If we intend to find the inverse of the function, f(x) = 3+ V2 - 1, we have to first add 1 to both sides of the equation and subsequently subtract 3 from both sides of the equation before taking the square root of both sides to obtain the inverse function.

Step-by-step explanation:

I hope this helps you :)
