Answer:
y + 1 = 8/9(x +4)
Step-by-step explanation:
Find the slope: [7- (-1)]/ [5 - (-4)] = 8/9
Using (-4, -1)
y-(-1) = 8/9[x- (-4)]
y + 1 = 8/9(x +4)
Answer: 4

Divide by 360
X=4
Answer:
B. -6 does not belong to the domain but belongs to the range of f(x).
Step-by-step explanation:
We have the function, 
.
So, the domain of the function is obtained when 
i.e. 
That is, the domain is {x | x≥ 7}.
Now as we have,
→ → 
→ 
→ 
.
That is, 
Thus, the range of the function f(x) is {y | y≤ 1}.
Thus, we can see that,
-6 does not belong to the domain but belongs to the range of f(x).
the complete question is
If we add 5 to the denominator And subtract 5 from the numerator of a fraction ot reduces to 1/7. if we subtract 3 from the numerator and add 3 to its denominator ot reduces to 1/3. find the fraction.
Let
x/y-----------> the fraction
we know that
(x-5)/(y+5)=1/7------>7*(x-5)=(y+5)-----> y=7x-35-5----> y=7x-40----> equation 1
(x-3)/(y+3)=1/3----> 3*(x-3)=y+3----> y=3x-9-3----> y=3x-12------> equation 2
equate equation 1 and equation 2
7x-40=3x-12-----> 7x-3x=40-12------> 4x=28-----> x=7
y=3x-12------> y=3*7-12-----> y=9
x/y=7/9
the answer is
the fraction is 7/9
Answer: total withdrawal: 80+ 160= 240
Step-by-step explanation:
She withdrawl from her bank acount for 4 times for 20 dollars means that you multiply 20 with 4= 80 and she also made two withdrawal for 80 so you take 80 mutiply by 2= 160 plus all together is the total amount of withdrawal that she took from the bank
