From x=1 to x=5
x=1 is starting time
x=time
y=mx+b
m=slope
b=yintercept
slope=(y2-y1)/(x2-x1)
for points (x1,y1) and (x2,y2)
(1,52000) and (5,116000)
slope=(116000-52000)/(5-1)=64000/4=16000
y=16000x+b
find b
(1,52000)
52000=16000(1)+b
52000=16000+b
minus 16000 from both sides
36000=b
the equation is
y=16000x+36000
at 12 years, x=12
y=16000(x)+36000
y=16000(12)+36000
y=192000+36000
y=228000
sales at year 12 is $228,000
The square root of 729 is in fact 27, as it is a perfect square, but this is not well known, so we can figure it out like this:
What goes into 729 that are perfect squares? 81 and 9:
Take the square root of 81 (9) and the square root of 9 (3). Move these to the outside of the square root (they will multiply with 3 since 3 is multiplied to the square root in the original problem)
Now, just multiply:
Answer:
below smallest to greatest:
Step-by-step explanation:
1) 1/4--> 3/8 --> 1/2
b) 4/9 --> 1/2 --> 2/3 -->5/6
c) 1/5--> 7/10 --> 3/4--> 4/5
Answer:
1. n = 13
2. x = -30
3. y > -18
4. n < -0.75
5. 101 t-shirts
Step-by-step explanation:
1. multiply both sides by 2, then add both sides by 2, making n = 13
2. divide both sides by -3, then subtract both sides by 5 making x = -30
3. divide both sides by -2, when dividing by a negative number, you need to switch the inequality sign to the other side
4. divide both sides by 4, then divide by -2(you need to switch the inequality sign to the other side), then add -8 and 2.5, then add 5.5 to both sides
5. the equation is 150 = 5x - 45. 45 is because they have already earned it, and 5x is how much each shirt will cost. The solution is then 101.
Hope this has a helped a little at least :P
