When 36 is decreased by 75%, the result is 9.
75% of 36 is 27.
36 - 27 = 9
Step-by-step explanation:
let the unknown members be X
At first, the club had 20 + X members
After the first year,
2( 20+X)
The second year,
2( 20 +X/2) +40
The third year,
3[2(20+ X/2) +40]
Total number =
20+X + 2(20+X) + 2( 20 +X/2) +40 +3[2(20+ X/2) +40]
= 20+ X + 40+ 2X + 40 +2X/2 +40 +3[40+2X/2 +40]
= 20+40+X +2X +40+X+ 40 + 3[ 40+40+X]
= 60 +3X +80+X + 3[80+X]
= 140+4X + 240+3X
=380 + 7X
-380=7X
X = -54.3
Answer:
93
Step-by-step explanation:
Just divide the numbers.
Answer: b) (x - 2)(x + 1)(x + 3)
<u>Step-by-step explanation:</u>
Look at the graph to find the x-intercepts (where the graph crosses the x-axis).
x = 2 x = -1 and x = -3
Now rearrange each of those equation so they are equal to zero:
x - 2 = 0 x + 1 = 0 and x + 3 = 0
Next, combine them (using multiplication):
(x - 2) (x + 1) (x + 3) = 0
Lastly, evaluate the sign of the a-value (coefficient of the polynomial):
Since the right side of the graph goes to POSITIVE infinity, then the a-value is positive.
Y = mx + b
4 = 6(1) + b
b = -2
equation
y = 6x -2
