Answer:
see the explanation
Step-by-step explanation:
we know that
If two lines have the same slope, then the lines are parallel.
If two parallel lines have the same y-intercept or any point in common, then the lines are identical when graphed
If two parallel lines have different y-intercept, then the lines are different parallel lines when graphed
Answer:
x-intercept = 30/6 = 5
y-intercept = 30/5 = 6/1 = 6.00000
Step-by-step explanation:
calculate the Y-intercept:
Notice that when x = 0 the value of y is 6/1 so this line "cuts" the y axis at y=6.00000
y-intercept = 30/5 = 6/1 = 6.00000
Calculate the X-Intercept :
When y = 0 the value of x is 5/1 Our line therefore "cuts" the x axis at x= 5.00000
x-intercept = 30/6 = 5
Answer:
Solution set = {(-1,-2/5)]
Step-by-step explanation:
64p=-16+8p-40p²
64p-8p=-16-40p²
56p+16+40p²=0
40p²+56p+16=0
8(5p² +7p+2)=0
5p²+5p+2p+2=0
5p(p+1) +2(p+1)=0
(p+1)(5p+2)=0
p+1=0; 5p+2=0
p=-1; p=-2/5
Amount spent on coffee= $70 - $48.31 = $21.69
Coffee cost $7.23 per pound
No of pounds of coffee bought = Amount in $ / Cost in $ per pound
= 21.69 / 7.23
= 3
3 pounds of coffee was bought
Answer:
BD = 3.75 units
Step-by-step explanation:
Given AD is an angle bisector then it divides the opposite side into segments tat are proportional to the other 2 sides, that is
= 
, substitute values
= 
( cross- multiply )
8 BD = 30 ( divide both sides by 8 )
BD = 3.75 units
