Answer:
p = 17 and -15
Step-by-step explanation:
If q is directly proportional to (p-1)², this can be written as;
q = k(p-1)²
If q = 20 when p = 3
20 = k(3-1)²
20 = 2²k
20 = 4k
k = 5
To get p wen q = 80
80 = 5(p-1)²
16 = (p-1)²
p-1 = ±√16
p-1 = 16 and p-1 = -16
p = 17 and p=-16+1
p = 17 and -15
Answer:
x = -4
Step-by-step explanation:
2x+4(2x+7)=3(2x+4)
Distribute
2x+8x + 28 = 6x +12
Combine like terms
10x +28 = 6x +12
Subtract 6x from each side
10-6x+28 = 6x +12 -6x
4x +28 = 12
Subtract 28 from each side
4x+28-28 = 12-28
4x = -16
Divide each side by 4
4x/4 = -16/4
x = -4
You can make 11 batches of brownies. Divide 8.5 (8 1/2) by .75(3/4)
Answer:
Step-by-step explanation:
<u>Actual question is:</u>
- logf 4(3d) + log4 1 = log4 3d
<u>Solution:</u>
- logf 4 + logf (3d) + 0 = log4 (3d)
- logf 4 + logf (3d) = log4 (3d)
<u>If we assume f = 4, then</u>
- log4 4 + log4 (3d) = log4 (3d)
- log4 4 = 0
but log4 4 = 1
Therefore the statement is False
The answer is 18/5 and simplify that and u get 3 3/5.
