Answer:
-17 x + 60 y + 33
Step-by-step explanation:
3(7-3x+8y)-4(2x-9y-3)
Distribute
21 -9x+24y -8x +36y +12
Combine like terms
21+12 -9x-8x+24y +36y
33 -17x +60y
Rearringing the terms
-17 x + 60 y + 33
it will be 63.1(56TAN) or 93.549
The form of the equation you would have to write would be y = mx + b.
M being the slope of the line and b being the y intercept of the line
Answer:
19.1
Step-by-step explanation:
13²+14²=365
√365≈ 19.1
Answer:
<h2> 0.027</h2>
Step-by-step explanation:
The number of groups of 5 boys that we can have from 7 boys is 7C5 = 21
The number of groups of 5 boys that we can have from 12 students is
12C5 = 792
then the probability = 21/792 = 0.026515151515
by the way you can calculate 12C5 and 7C5 using a calculator.
