Answer:
y = - 3x - 22
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 )
y = 
x + 1 ← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= - 3 , then
y = - 3x + c ← is the partial equation
To find c substitute (- 6, - 4) into the partial equation
- 4 = 18 + c ⇒ c = - 4 - 18 = - 22
y = - 3x - 22 ← equation of perpendicular line
Answer:
Step-by-step explanation:
1 and 2/3 rotations. The little gear full rotation is equal to 1/6 of the big gears rotation. So if the big gear rotates once then its equal to 6 of the small rotations the extra 4 of the 10 rotations then becomes 4/6 of the big gears rotation or if simplified further, 2/3. This is my way of solving these questions
Answer:
-7.65
Step-by-step explanation:
First youll need to add all the numbers together to get the cost of one tire
89.95 + 3.25 + 2.60 + 3.80 = $99.60
now that we know how much one tire costs, we can multiply the price of one tire by two to found out his final bill
99.60 x 2 = $199.20
Pete's final bill is $199.20
let me know if you have any other questions
