Answer:
Infinitely many solutions.
Step-by-step explanation:
The two sides are the exact same therefore x can be anything
Answer:
d ≈ 87.85 yards
Step-by-step explanation:
The circumference ( C) of a circle is calculated as
C = πd ( d is the diameter ), then
276 = πd ( divide both sides by π )
= d , so
d ≈ 87.85 yards ( to the nearest hundredth )
Answer:
(-4,-2)
Step-by-step explanation:
Point f is on x -4, which is in the first slot and y -2 which is your second slot
In a quadratic equation of the form (ax^2 + bx + c), the discriminant is equal to (b^2 - 4ac).
So for the first question it would be
4^2 - 4*(6*-2) = 64
Second question (-7)^2 - 4*(9*5) = -131
You can do the rest.
