Answer:
1. k=2
2. b=2f
3. 68
Explanation
1. y=kx (replace x&y with 2 values)
12=k(6) (isolate k)
/6 /6
2=k *check with another value to see if k truly is 2
2. since the constant of variation is 2, we can see that 2x the number of flowers make up the birds. so...
b(birds/y-value)=2(constant)f(number of flowers)
b=2f
3. input 34 into f, since there are 34 flowers
b=2*34 (use mental math)
b=68
in other words, there will be 68 birds.
Answer:
intersect at (-1,-3)
Step-by-step explanation:
y = 4x + 1. the points should be at (0,1) and (-0.25,0) and is an infinite line in both directions.
y = -2x - 5. the points should be at (-2.5,0) and (0,-5) and is an infinite line in both directions.
both the lines meet at (-1,-3) so make a point at that location
A=4 4 times 12 is 48 minus 24 is 24
Answer:28 bags with 17 cents left over
Step-by-step explanation: First, subtract the amount of 37.85 from what he started out with, 52.02. You should get 14.17.
Then, if we have 14 whole dollars and the bags each cost 50 cents, then we can just multiply 14 by 2, since each dollar equals 50 cents times 2.
EX: $1=50 cents x2. So 14 dollars x2 would be like saying the first amount 50 cents doubled. You should get 28 bags, with 17 cents left over :). Let me know if this makes sense! I really hope this helps you.
-4
Because 15x-7x= 8x
8x+5x= 13x
13x= -52
-52 / 13= -4
x = -4
