Answer:
B
Step-by-step explanation:
So we have the function:
To find the inverse, flip f(x) and x, change f(x) to f⁻¹(x), and solve for it. Thus:
Subtract 32 from both sides:
Multiply both sides by 5/9. The right side will cancel. Thus:
Our answer is B.
And we're done!
A. (2,0) (0,-3)
B. slope= 3/2
C. y= 3/2x-3
D. 3/2x+y= -3
Answer:
by using the identity a square - b square = (a+b)*(a-b)
a = x+y
b=4-x
= (x+y + 4-x)(x+y - 4-x)
y+4 * x+y -4+x
y+4*2x+y-4
2xy+y square -4y + yx + 4x + 4y - 16 +4x
3xy +y square + 8x -16
Step-by-step explanation:
60% choose band......40% choose chorus
30% who are taking band are girls......30% of 60% is (0.3 * 0.6) = 0.18 or 18%..so 18% are girls.
70% who take chorus are girls....70% of 40% is (0.7 * 0.4) = 0.28 or 28%...so 28% are girls.
18% + 28% = 46%....so a total of 46% taking band and chorus are girls.....so that leaves (100% - 46%) = 54% ( or 0.54) are boys
36: 4 ,9
10.8: 2,4
Hope this helps!! ;D
