Answer:
About 14
Step-by-step explanation:
For this you use the pythagorean theorem, which says a(a) + b(b) = c(c)
The sides that make the right angle are legs which is A and B
The other side is the hypotenuse which is C
So you set it up as
11(11) + b(b) = 18(18)
121 + b(b) = 324
324 - 121 = 203
so b(b) = 203
but 203 is b squared so you need to find the square root of 203 which is about 14.2478.
If you round that it is 14
Check
11(11) + 14(14) = 18(18)
121 + 196 = 324
317 = 324
so about
A constant function is a horizontal line.
The slope is: y = 3x + 6
The y-intercept is: 6
Remove parentheses
3m - 7m+12 = 2 m-3
collect like terms
3m-7m-12 = 2m-6
move terms
-4m - 12 = 2m-6
collect the like terms and calculate
-4m-2m = -6+12
divide both sides by -6
-6m=6
m= -1
