Answer: y = -2x + 10
Step-by-step explanation:
Two lines are said to be perpendicular if the product of their slope = -1, that is , if 
is the slope of the first line and 
is the slope of the second line , if the two lines are perpendicular , then = -1
The equation of the line given :
y = 1/2x - 1
comparing with the equation of line in slope intercept form
y = mx + c , where m is the slope and c is the y - intercept , it implies that
= 1/2
Therefore :
= -2
To find the equation of the line with slope -2 and passes through the point ( 3 , 4 ) we will use the formula
= m (
)
y - 4 = -2 ( x - 3 )
y - 4 = -2x + 6
y = -2x + 6 + 4
y = -2x + 10
The car's average rate is 43.7 mph. The bicycle's average rate is 12.3 mph.
To get this solution, let the bicycle's average rate be (x) and the car's average rate be (x + 31.4) mph.
Distance= Speed x Time
364 = (x + x + 31.4) 6.5
364 = (2x + 31.4) 6.5
364/6.5 = 2x + 31.4
56 = 2x + 31.4
56 - 31.4 = 2x
24.6 = 2x
24.6/2 = x
12.3 = x
x = 12.3 mph
x+31.4 = 43.7 mph
The only correct answer would be D, all you do it plug in the x and y values, such as (0,5)
A) 5 = (0 + 11) - 5
5 = 11 - 5
5 = 6
B) 5 = 11(0) - 5
5 = 6
C) 0 = 11(5) + 5
0 = 55 + 5
0 = 60
D) 5 = 11(0) + 5
5 = 5
Answer:
110
Step-by-step explanation:
measure of arc YX is 35 ×2 = 70
Then 180 - 70 =110 is the measure of WX
