Answer:

The equation of the circle is (x+3)^2 + (y-4)^2 = 16.

Step-by-step explanation:

The equation of a circle can be calculated if the center and the radius are known. The equation of a circle is given by (x-h)² + (y-k)² = r²

Where (h, k) = center coordinates and r = radius.

Can someone help me solve for x on number 18 and explain how you did it thank you ;)

torisob [31]

Answer:

x = 19°

Step-by-step explanation:

Given that < (6x + 1)° + < (3x + 8)° are supplementary angles whose sum = 180°

6x + 1 + 3x + 8 = 180°

Add common terms:

9x + 9 = 180°

Subtract 9 from both sides:

9x + 9 - 9 = 180° - 9

9x = 171°

Divide both sides by 9 to solve for x:

$\frac{9x}{9} = \frac{171}{9}$

x = 19°

Luke and Aisha are traveling on the same road in the same direction. Luke is driving at a rate of 50 miles per hour, and Aisha

Nataly_w [17]

If x is the time, in hours, then:

x(55)=x(50)+15

5x=15

x=3 hours before Aisha is ahead of Luke

hope this helps you!
