Answer:x=-1/6,y=0
Step-by-step explanation:
6x-y=-1....(1)
6x+y=-1...(2)
From (2) make y the subject of formula
Y=-1-6x...(3)
Substitute (3)in (1)
6x-(-1-6x)=-1
6x+1+6x=-1
Collect like terms
6x+6x=-1-1
12x=-2
X=-1/6...(4)
Substitute (4) in (3)
Y=-1-6(-1/6)
Y=-1+1
Y=0
Therefore,x=-1/6
Y=0
I don't have the first answer sorry but I do know the second answer, you add up 7+4 which gives you 11 then it asked you about the odds in favor of picking green marble, the answer is 7:11
Let's use the slope intercept form of a line which is:
y=mx+b where m=slope and b=y-intercept.
Mathematically m=(y2-y1)/(x2-x1) and the y-intercept is just the value of y when x is equal to zero, where the line intercepts the y axis...
First you want to find the slope by finding two clearly identifiable points on the graph...I'll pick (4,4) and (0,1), now we can calculate the slope or "m"...
m=(4-1)/(4-0)=3/4 so now we can say our line is:
y=0.75x+b, using point (4,4) we can now solve for b.
4=0.75(4)+b
4=3+b
b=1 so the line is"
y=0.75x+1
Answer:
Step-by-step explanation:
d = distance from hive to flowers, in feet
flying time = 23 min - 18 min = 5 min = 300 sec
time flying to flowers = d ft × (1 sec)/(10 ft) = (d/10) sec
time flying to hive = d ft × (1 sec)/(6 ft) = (d/6) sec
d/10 + d/6 = 300 sec
:::::
d/10 + d/6 = 3d/30 +5d/30 = 8d/30 = 300
d = 300×30/8 = 1,125 ft
