Answer:
y=18
Explanation:
input x=5
rule ——-> 4x-2
=4x5-2
=20-2
=18 {scrutinize}
output y=18
Answer:
The answer is b
Step-by-step explanation:
Y = 12x - 5x - 2
first simplify the equation by subtracting like terms (in this case):
12x - 5x = 7x
y = 7x - 2
Since you are finding the x, you must isolate the x. Do the opposite of PEMDAS.(Note: because there is a equal sign, what you do to one side, you do to the other)
y = 7x - 2
y (+2) = 7x - 2 (+2)
y + 2 = 7x
(y + 2)/7 = 7x/7
x = (y + 2)/7
x = (y + 2)/7 is your answer
hope this helps
Answer:
B - x=5
Step-by-step explanation:
If y=25 is 250% more than y=10, so multiply 2 by 250% and you get 5
Answer:

Explanation:
Let's begin writing down everything
(X×(-11)+5)×(-9)+X-55
Now we can multiply
-9(-11X+5)+X-55
99X-45+X-55
And so we get
100X-100
Factorize 100
100(x-1)
