Answer:
(0,5)
Step-by-step explanation:
Perpendicular lines have slopes which are negative reciprocals of each other. The slope of the line y=1/2x + 6 is 1/2. The slope perpendicular to it is -2.
Using m=-2, substitute it and (4,-3) into the point slope form and simplify to find the y-intercept.
The equation is now in slope intercept form y=mx+b and b is the y-intercept. The y-intercept of y=-2x+5 is (0,5).
1 3/5 x 2 3/4
= 8/5 x 11/4
= 22/5
= 4 2/5 (4 and 2/5)
Solve for x
6x+5y=-15
subtract 6x from both sides
5y=-6x-15
divide both sides by 5
y=-6/5x-3
Answer:
$111.56
Step-by-step explanation:
125% × 89.25 = 111.5625
We know that one inch has 16.5 turns.
To know the number of turns in 2.5 inches of thread, we will simply do a cross multiplication as follows:
number of turns = (2.5 x 16.5) / 1 = 41.25 turns
