Answer:
y = 148
Step-by-step explanation:
First, we use the point-slope form of the equation of a line to find the equation of this line.
y - y1 = m(x - x1)
y - 4 = 6(x - 3)
y - 4 = 6x - 18
y = 6x - 14
Now we let x = 27 and find y.
y = 6(27) - 14
y = 162 - 14
y = 148
Answer:
b
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ← r is the radius
The circle shown is centred at the origin and has a radius of 5, thus
x² + y² = 5² ⇒ x² + y² = 25 → b
Answer:
Yes
Step-by-step explanation:
Because 9, 12, and 15 are Pythagorean triples
