Answer:
(f + g) (x) = 5x - 11
(f - g) (x) = x + 3
Step-by-step explanation:
f(x) = 3x - 7
g(x) = 2x - 4
to find ; (f + g) (x) and (f - g) (x)
now,
(f + g ) (x) = f (x) + g(x)
= (3x - 7) +( 2x - 4 )
= 3x - 7 + 2x - 4
= 5x - 11
again ,
(f - g ) (x) = f(x) - g(x)
= (3x - 7) - (2x - 4)
= 3x - 7 - 2x + 4
= x + 3
Answer:
1.14x = 2x
x = (0.12)(1.14)x
Step-by-step explanation:
We are going to express the data in an equation form:
If <em>x </em>was the number of cases there was in 2000 ⇒<em>currently there are 1.14x </em>cases of measles.
But the question also tells us that the number of cases now is also 2 times what it was in 2000.
So we have that <u>1.14x = 2x</u>
<u />
It also tells us that the number of measles back in 2000 was 12% of what it is now.
<u>x = (.12) 1.14x</u>
<u />
We can't really solve these equations since the problem doesn't give us any more information (I am assuming there was another part of the problem before this one that wasn't written here).
Answer:
x= -1
Step-by-step explanation:
Given data
We have the expression as
(x+1)/(x+1)= 1/2
let us first cross multiply
2(x+1)=(x+1)
2x+2=x+1
collect like terms
2x-x=1-2
x= -1
Hence the value of x=-1
