You'd divide $19.32 by $.69, that is 28 donuts then you'd subtract 24 from 28 to find out how any MORE donuts she bought than two dozen so the answer is 4 donuts.
Answer:
m
Step-by-step explanation:
Answer:
y = - 
x + 2
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 )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, 7) and (x₂, y₂ ) = (6, - 8)
m = 
= 
= - , then
y = - x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (6, - 8) , then
- 8 = - 10 + c ⇒ c = - 8 + 10 = 2
y = - x + 2 ← equation of line
The answer is 5 feet.
1/4 = 1.25/x
x = 4•1.25
x = 5
When a line is perpendicular to another line, the slope is the negative reciprocal of the other line's slope. So in this case, the slope would be 1, since the negative reciprocal of -1 is 1/1 which is 1.
To find the y-intercept, you have to substitute the point (8,2) into y = mx + b
2 = 1(8) + b
b = -6
The equation is y = x - 6
