Answer:

Step-by-step explanation:
To write the equation of a line use the point slope formula
. Find m by using the slope formula with the points.

Since the line is parallel, it will have the same slope.
Substitute m = -1/3 and (-3,-4).

Answer:
k = +10 or -10
Step-by-step explanation:
It's given in the question that the roots of the eqn. are real and equal. So , the discriminant of the eqn. should be equal to 0.






Answer:
The coordinates are ( 4, -3).
Step-by-step explanation:
We can find the coordinates by solving the 2 equations
y = 1/4x-4
y = -1/2x-1
As both left sides of the equation are y we can say:
-1/2x-1 = 1/4x-4
-1/2x - 1/4x = -4 + 1
-3/4 x = -3
x = -3 * -4/3
x = 4.
- and y = 1/4(4) - 4 = -3.
Multiply the number of tosses by the percent of heads:
20 tosses x 0.75 = 15
The answer is 15.
