Can some help me with this question
Luden [163]

To find the equation of this line in slope-intercept form (y = mx + b, where m is its slope and b is its y-intercept), we naturally need the slope and the y-intercept. We can see that the line intersects the y-axis at the point (0, 4) so our y-intercept is 4, and the line rises 4 along the y-axis for every 2 it runs along the x-axis, so its slope is 4/2 = 2. With this in mind, we can write the line's equation as

y = 2x + 4

Circle D is below what is the arc measure of BC in degrees
maks197457 [2]

Answer:

84°

Step-by-step explanation:

\because (13n - 16) \degree + (7n  + 12) \degree + (6n)\degree \\= 360\degree \\  \\  \therefore \: (26n - 4) \degree= 360\degree \\  \\  \therefore \: 26n - 4= 360 \\  \\ \therefore \: 26n = 360 + 4 \\  \\ \therefore \: 26n = 364 \\  \\ \therefore \: n =  \frac{364}{26}  \\  \\ \therefore \: n =  14 \\  \\\because  m\overset { \frown}{BC} = (6n)°\\  \\\therefore \:m \overset { \frown}{BC} =(6\times 14)°  \\  \\   \huge \purple {\boxed {\therefore \:m\overset { \frown}{BC}= 84°}} \\

6 times a number is 27 less than the square of that number. Find the positive solution.
Verdich [7]

Let x = your number.

6x = x^2 - 27. Subtract 6x from each side.

0 = x^2 - 6x - 27. Factor

0 = (x-9) (x+3). Set each term equal to zero

(x+3) = 0. Subtract 3 from each side.

x = -3. This is the negative solution.

(x-9) = 0. Add 9 to each side.

x = 9. This is the positive solution.
