Answer:
(f + g)(x) = 7x - 1
Step-by-step explanation:
Given : f(x) = 5x – 2 and g(x) = 2x + 1
We have to find (f + g)(x)
Consider (f + g)(x) = f(x) + g(x)
Also, given f(x) = 5x – 2 and g(x) = 2x + 1
Substitute, we have,
f(x) + g(x) = 5x - 2 + 2x + 1
Like Terms are terms having same variable with same degree.
Simplify by adding like terms, we have,
f(x) + g(x) = 5x + 2x - 2 + 1
f(x) + g(x) = 7x - 1
Thus, (f + g)(x) = 7x - 1
I think it is 42 because 2.75 + 4.25 is 7 x 6= 42
Answer:
8
Step-by-step explanation:
i would say in between 8&9 bc the square root of 8 is 36 and 9 is 81 and that's right in the middle
Answer:
x5+5=25/6
Step-by-step explanation:
You can create an equation by making an equation with -1/6 and then replacing -1/6 with x. (-1/6)(5)+5=25/6. This is two step because you first have to subtract from both sides and then divide.
Answer:
n = -2
Step-by-step explanation:
we apply distributive property:
-4(8+5n)=8
-4*8 -4*5n = 8
we have:
-32 -20n = 8
we add 32 to both sides of the equation:
-32+32 -20n = 8 +32
we have:
-20n = 40
we divide by -20 to both sides of the equation:
-20n/-20 = 40/-20
we have:
n = -40/20
finally we have:
n = -2
