Answer:

d=i√7, -i√7

Step-by-step explanation:

-2d^2 -4=10     add 4 to both sides

-2d^2 = 14        divide each term by -2

d^2= -7              take the square root of each side to get rid of the exponent

d= = √-7           ( put a slash(short line above that = sign ) in the second equal sign)

d = =i√7

Write an equation of the line that passes through the point (4,5) and has a slope of -2.
Marina86 [1]

Answer:

y = - 2x + 13

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 2 , then

y = - 2x + c ← is the partial equation

To find c substitute (4, 5) into the partial equation

5 = - 8 + c ⇒ c = 5 + 8 = 13

y = - 2x + 13 ← equation of line
