Answer:
18
Step-by-step explanation:
4*3 = 12
1/2 * 3 * 4 = 6
so the investigator found the skid marks were 75 feet long hmmm what speed will that be?
nope, the analysis shows that Charlie was going faster than 35 m/h.
now, assuming Charlie was indeed going at 35 m/h, then his skid marks would have been
Y=65
X=5
X=12
Y=?
65—->5
?——>12
Cross multiply
Y= (65x12) / 5
Y= 780 / 5
Y= 156
To check add the Y value in and remove an X value
65——> ?
156 ——> 12
Cross multiply
X= (12x65) / 156
X= 780 / 156
X= 5
You got the right answer. Hope this helped.
M in (-oo:+oo)
m+11 = (1/4)*m-(2*m) // - (1/4)*m-(2*m)
m-((1/4)*m)+2*m+11 = 0
m+(-1/4)*m+2*m+11 = 0
11/4*m+11 = 0 // - 11
11/4*m = -11 // : 11/4
m = -11/11/4
m = -4
m = -4
Answer: B
explanation: B is the right answer because it passes the vertical line test while the others do not. the others would have more than one outcome for the same income, therefore it wouldn’t be a function
