Answer:
2 1/6 hours.
Step-by-step explanation:
It walks 1 1/2 miles in 3 1/4 hours.
So it walks 1 mile in (3 1/4 ) / (1 1/2) hours.
= 13/4 / 3/2
= 13/4 * 2/3
= 26/12 hours
= 2 1/6 hours.
Answer:
b. (3,0)
e. (5,-6)
f. (2,1)
Are solutions to the system of inequalities
Step-by-step explanation:
b. (3,0)
0 ≤ -2(3) + 6
0 ≤ 0 is true
3 > 1 is true
e. (5,-6)
-6 ≤ -2(5)+6
-6 ≤ -4 is true
5 > 1 is true
f. (2,1)
1 ≤ -2(2)+6
1 ≤ 2 is true
2 > 1 is true
Answer:
4.18
Step-by-step explanation:
What the regression is a conflict
Answer: 
Step-by-step explanation:
Slope of two lines that are perpendicular to each other is 1.
If one line is 
, then its slope = 3 [by comparing to the linear equation y= mx+c, here m=3]
Let n be the slope of the required line, then
Equation of line with slope n and passers through (a,b) is
Equation of line with slope n= 
and passes through point ( 0,-4) :
Hence, Required equation :
