15 = -3(2c + d) (Solve for c)

Paha777 [63]

Answer:

(15+3d)/6 = c

2 1/2 + 1/2d = c (more simplified)

Step-by-step explanation:

15 = -3(2c +d)

15 = -6c -3d

+3d +3d

15 +3d = -6c

/-6 /-6

(15+3d)/6 = c

2 1/2 + 1/2d = c

Find the circumference of this circle. Round to the nearest tenth.<br><br> Area= 63.6 inches squared

Virty [35]

Answer:

C = 28.048

Step-by-step explanation:

Circumference = 2pi(r)

Area = pi(r)^2

62.6 = pi(r)^2

r^2 = 62.6/pi

r^2 = 19.926

r = 4.464

Therefore, circumference = 2pi(4.464)

= 28.048

Write an equation of a line in point-slope form that has a slope of -2 and passes through (5, -1).

gavmur [86]

Answer:

$y+1=-2(x-5)$

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and the slope.

We will substitute $m=-2$ and $x_1=5\\y_1=-1$ .
