Hello! So I understood your question as what M means. M is 49, 49-28=21
48, multiply -1 by -4 then multiply 4 by 12
PEMDAS
Correct answer: 1) (f/g)(x)
Solution: f(x)=x^2-6x-27=(x+3)(x-9)
Answer:
The explicit formula for this geometric sequence is 27.3(n-1)
Slope intercept form is y=mx+b
m=slope
b=y intercept
slope is 4
y=4x+b
subsitute if iin (x,y) form
so x=3 and y=-2 is one solution
subsitute
-2=4 times 3+b
-2=12+b
subtract 12 from both sids
-14=b
the equation is y=4x-14
