If f(x)=4x+1 and g(x)=x^2-5, find (f+g)(x)
kvasek [131]

Answer:

x^2 + 4x - 4.

Step-by-step explanation:

(f + g)(x) is the same thing f(x) + g(x), which is the same thing as (4x + 1) + (x^2 - 5).

(4x + 1) + (x^2 - 5)

= x^2 + 4x + 1 - 5

= x^2 + 4x - 4

Hope this helps!

Emily spends $28 on food. This amount of 4/9 of her allowance, what is Emily’s allowance?
Fantom [35]

Answer:

$63

Step-by-step explanation:

so we want to find 9/9 of her allowance, which is 100%

we could use a proportion:

let 'a' = full allowance

\frac{28}{1} ÷ \frac{4}{9} = \frac{a}{1} ÷ \frac{9}{9}

when we divide fractions we multiply by the reciprocal to get:

28 x 9/4 = a

a = 252/4

a = 63
