F(x) = 2x – 5 13<br> g(x) = 3x – 2 26<br> Find f(9) +49(9)

podryga [215]

Answer: -694

Step-by-step explanation:

Let's assume we have to find $f(9)+g(9)$ with the given functions:

$f(x)=2x-513$ (1)

$g(x)=3x-226$ (2)

If we want to find $f(9)$ we have to substitute the $x$ by $9$ :

$f(9)=2(9)-513$

$f(9)=-495$ (3)

If we want to find $g(9)$ we have to substitute the $x$ by $9$ :

$g(9)=3(9)-226$

$f(9)=-199$ (4)

Finding $f(9)+g(9)$ :

$f(9)+g(9)=-495+(-199)$

Finally:

$f(9)+g(9)=-694$

Solve (Y+5)^3/2=4 where y is a real number

koban [17]

Answer:

$y {}^{2} + 10y = - 33.5$

Step-by-step explanation:

(y+5)(y+5)x3/2=4

Y(y+5)+5(y+5) x 3/2=4

$y {}^{2} + 5y + 5y + 25 \times 3 \2 = 4$

$y ^{2} + 10y + 75 \2 = 4$

$y {}^{2} + 10y + 37.5 = 4$

$y {}^{2} + 10y = 4 - 37.5$

$y {}^{2} + 10y = - 33.5$
