Answer:
B
Step-by-step explanation:
Quadratic inequalities are inequalities involving quadratics.
A is not an inequality.
B is an inequality and we can rewrite B as:
So, B is a quadratic inequality, and is the answer.
C is not a quadratic. The x terms are not squared.
Likewise, D is not a quadratic either since no x terms are being squared.
Answer:
y = x + 4
Step-by-step explanation:
Assuming you require the equation of the line.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (8, 8) and (x₂, y₂ ) = (10, 9)
m = =
, then
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, 8) , then
8 = 4 + c ⇒ c = 8 - 4 = 4
y = x + 4 ← equation of line
