You have two points
(12,2200) and (10,3000) You have enough information to set up an equation.
x1 = 12
x2 = 10
y1 = 2200
y2 = 3000
The slope = (y2 - y1)/ (x2 - x1)
The slope = (3000 - 2200) / (10 - 12)
Slope = 800 / - 2
slope = - 400
So far what you have is y = - 400x + b
To get b just use one of the points.
(10,3000)
y = - 400x + b
3000 = -400*10 + b
3000 = - 4000 + b Add 4000 to both sides.
3000 + 4000 = b
b = 7000
Answer y = - 400x + 7000
What happens if you use (12,2200)
y = -400*12+ 7000
y = - 4800 + 7000
y = 2200 As it should.
Answer:
225
Step-by-step explanation:
225/3 = 75
225/6 = 37.5 (since this is not a whole number it's not a multiple of 6)
Final answer = 225
Hope this helps!
Answer:
1.17
Step-by-step explanation:
(MUCH BETTER!)
From the definition of the sin of an angle, you know:
sin(45°) = AC/AB = 4/AB ⇒ AB = 4/sin(45°) ≈ 5.6569
sin(63°) = AC/AD = 4/AD ⇒ AD = 4/sin(63°) ≈ 4.4893
Then the difference AB-AD is:
AB -AD = 5.6569 -4.4893 = 1.1676
AB -AD ≈ 1.17 units
Sorry this took me so long to answer!
Answer:
Step-by-step explanation:
x + 4y = 15
8x - 4y = -60
9x = -45
x = -5
-5 + 4y = 15
4y = 20
y = 5
(-5, 5)
25% of 32= 8
8-32=24
50% of 24=12
24-12=12
There would be 12 peanuts left
