Answer:
-6F
Step-by-step explanation: It would be 5F(4hr) = 20F. So if you have 14F subtract 20F you get -6F. Hope this helped.
True,
4a - 3b
4(6) - 3(1)
24 - 3 = 21
Answer:
Each tulip costs $1.50
Step-by-step explanation:
First, write an equation using the numbers given. It should look like this:
2.25(8) + 5x = 25.50
Next, multiply 2.25 by 8 to get: 18 + 5x = 25.50. Then, subtract 18 from both sides:
18 + 5x = 25.50
-18 -18
5x = 7.50
Finally, divide both sides of the equation by 5 to get $1.50
So, each tulip costs $1.50. Hope this helped!
Answer:
Step-by-step explanation:
2^(-3) = 1/2^3 = 1/8
A minus means put the number in the numerator if it was in the denominator.
A minus means put the number in the denominator it was in the numerator.
If there is no denominator, create one.
Answer:
Step-by-step explanation:
15. (-4-3)/(-5-0)= -7/-5= 7/5
y - 3 = 7/5x - 0
y = 7/5x + 3
16. (-2-3)/(4-0)= -5/4
y - 3 = -5/4x - 0
y = -5/4x + 3
17. (-3+5)/(0+3)= 2/3
y + 5 = 2/3(x + 3)
y + 5 = 2/3x + 2
y = 2/3x - 3
18. (-2-2)/(0+4)= -4/4= -1
y - 2 = -1(x + 4)
y - 2 = -x - 4
y = -x - 2
19. y - 3 = 1/2x - 0
y = 1/2x + 3
20. y - 2 = -(x + 1)
y - 2 = -x - 1
y = -x + 1
21. perp. -5/3
y + 5 = -5/3x + 0
y = -5/3x - 5
22. perp. 1/2
y + 1 = 1/2(x + 4)
y + 1 = 1/2x + 2
y = 1/2x + 1
23. perp. 3/4
y + 5 = 3/4(x + 4)
y + 5 = 3/4x + 3
y = 3/4x - 2
24. perp. 7/5
y - 4 = 7/5(x - 5)
y - 4 = 7/5x - 7
y = 7/5x - 3
