A = π • r^2
C = 2 • π • r
A = 25 π
C = 10 π
Your answer is C) 10π; A = 25π
Remember that (a-b)(a+b)=a²-b²
and (imaginary number)²=real
so if we have a+bi, then a-bi is the conguate because (a+bi)(a-bi)=a²+b²
if the complex number is a+bi the conjucate is a-bi
X= -1/3 Because the perpendicular lines always have a opposite reciprocal meaning if a slope is Positive it turns negative and the denominator becomes the numerator ex.3 is the same as 3/1 and the opposite of that would be 1/3 and if the slope is negative then the opposite reciprocal will be positive and with the denominator becoming the numerator
Answer:
y = (2/3)x + 9
Step-by-step explanation:
Equation of a straight line is y = mx + b. You are trying to finish the equation.
Note that:
m = slope = 2/3
b = y-intercept = 9
Plug in the corresponding numbers to the corresponding variables:
y = mx + b --> y = (2/3)x + 9
y = (2/3)x + 9 is your equation.
