Answer:
g(x) = (5x + 3)/ x - 7
Step-by-step explanation:
Let g(x) = y
y = (7x + 3)/x - 5
Make x the subject
xy - 5y = 7x + 3
xy - 7x = 5y + 3
x(y - 7) = 5y + 3
x = (5y + 3)/ y - 7
Therefore, the inverse of the function = (5x + 3)/ x - 7
Answer:
63 crayons/crowns/kranz (lol) and 48 markers (total: 111)
Step-by-step explanation:
25x3 = 75
75 - 12 = 63
12x4 = 48
Y=|x|-2
this can be easily seen by testing f(0) for all functions:
f1(0)=|0-2|=2
f2(0)=|x+2|=2
f3(0)=|x|-2=-2
f4(0)=|x|+2=2
f(0)=|x|=0, because you want to translate it 2 units down -2 is the expected value
First off, what's the slope of "r" anyway,

.
low and behold, since "r" is in slope-intercept form, notice, it has a slope of -1/2.
now, any line perpendicular to "r", will have a
negative reciprocal slope to it, that is,

so we're really looking for a line whose slope is 2, and runs through 4,-3,
1. you do 309 times 29
2. then when you got that answer write a zero at the bottom of that answer.
3. then do 309 times 9
4. then add those 2 answers together and you get your answer.
hope this helped!
