Answer:
y > 4x + 2
Step-by-step explanation:
Y is above the line so the value has to be greater than the line (or equal to, possibly). So it represents > or ≥
A dotted/dashed line is non-inclusive, so it represents < or >.
Since it is both above the line AND non-inclusive, we would use this sign:
>
and this equation :)
y > 4x + 2

Answer:
129.89 m²
Step-by-step explanation:
Area of a circle of radius r is A = πr².
If r = 6.43 m, then A = π(6.43 m)² = 129.89 m²

Step-by-step explanation:
Answer:
5x² - 10x - 15 = 0
Step-by-step explanation:
Given that the roots are x = 3 and x = - 1, then the factors are
(x - 3) and (x + 1) and the quadratic is the product of the factors, that is
f(x) = a(x - 3)(x + 1) ← a is a multiplier
Here a = 5, thus
f(x) = 5(x - 3)(x + 1) ← expand factors using FOIL
= 5(x² - 2x - 3) ← distribute parenthesis by 5
= 5x² - 10x - 15
Thus equation is
5x² - 10x - 15 = 0
