Answer:

See below.

Step-by-step explanation:

The equation is:

a / sin A = b / sin B = c / sin C

- where A, B and C are the 3 angles in the triangle and a, b and c are the sides opposite these angles respectively.

What is the center and radius of the circle? *<br> x² – 2x + 5+ y² = 8

wolverine [178]

Answer: center (1;0), radius = 2

Step-by-step explanation:

x² – 2x + 5+ y² = 8

x² – 2x + 5+ y² = x² – 2x + 1 + 4 + y² = (х-1)² +4 + y²

(х-1)² +4 + y² = 8

(х-1)² + y² = 8 - 4 = 4

(х-1)² + y² = 2²

center (1;0), radius = 2

Which of the following pairs of points are both solutions to the equation 2x-5y=6 ? and and and and

zhannawk [14.2K]

Answer:

Any points on the line y=2/5 x - 6/5. See picture below.

Step-by-step explanation:

Convert the equation to slope intercept form and graph it.

2x - 5y = 6

-5y = 6 - 2x

y = -2/-5 x + 6/-5

y=2/5 x - 6/5.

Locate each of the points listed on the graph. If they are a part of the line, then they are solutions.

What is the equation of the line x–3y=18in slope-intercept form?

Alekssandra [29.7K]

Answer:

$y=\frac{1}{3} x-6$

Step-by-step explanation:

Write down the slope-intercept form:

$y=mx+b$

Where m is the slope and b is the y-intercept.

To turn the equation into slope-intercept form, isolate y on the left-hand side:

$x-3y=18\\-3y=18-x\\y=-6+\frac{x}{3} \\$

Rearrange the equation a bit:

$y=\frac{1}{3} x-6$
