Answer:
Equation 2 is non-linear, Equation 1 is linear.
Step-by-step explanation:
A linear equation is an equation with a constant gradient and can be expressed in the form y = mx + c. Hence Equation 1 Satisfies this as it is in that form and has a constant gradient of 4. Equation 2 is not in the form y = mx + c since there is a square and hence its non-linear.

Step-by-step explanation:
An important property of equations is one that states that you can add the same quantity to both sides of an equation and still maintain an equivalent equation. ... If you think of an equation as being like a balance scale, the quantities on each side of the equation are equal, or balanced.
Answer:
h = -6
Step-by-step explanation:
Use the quadratic formula
ℎ

h=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}
h=2a−b±b2−4ac
Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.
