Answer:
-10x+2+x=-4x+12
-9x+2=-4x+12
-9x+4x+2=12
-9x+4x=12-2
-5x=10
x=-2
Step-by-step explanation:
we are given
Firstly, we will find domain of c(x) , d(x) and then (cd)(x)
and then we can find common domain
Domain of c(x):
we know that domain is all possible values of x for which domain is defined
we know that any function is undefined when denominator =0
x-2=0
x=2
so, domain of c(x) is all values of x except at x=2
Domain of d(x):
we know that domain is all possible values of x for which domain is defined
we know that any function is undefined when denominator =0
we don't have denominator here
so, domain of d(x) is all real values of x
Domain of (cd)(x):
we know that domain is all possible values of x for which domain is defined
we know that any function is undefined when denominator =0
x-2=0
x=2
so, domain of c(x) is all values of x except at x=2
so, common domain is all real values of x except at x=2
so, option-B........Answer
Answer:
21 = -10m - 3
Add 3 to both sides:
24 = -10m
Divide by -10 on both sides:
-2.4 = m
Answer:
12 inches
Step-by-step explanation:
So basically a decimal is moved based on how many zeros are in the dividing number
Ex. 51,000/100
because there are 2 zeros in the number one hundred, the decimal in 51,000 gets moved 2 places to the left
So it goes from 51,000 to 510
Ex. 16 * 1000
There are three zeros in the number 1000. This means three zeros will be added onto the number 16
So the answer would be 16,000
Hope this helps!
