For this question you can say:
10/2 = a/a-9 is equal to 2a = 10a - 90 
so now you should add -10a on both sides:
2a -10a = -90 ⇒ -8a = -90 ⇒ a = -90/-8 ⇒ a = 11.25 :)))
i hope this is helpful
have a nice day

10/2= a/a-9

10/2=a/a+-9

Multiply all terms by a and cancel

10a/2 = a+-9a

Simplify both sides of the equation

5a= -8a

Add 8a to both sides

5a+8a= -8a+8a

13a=0

Divide both sides by 13

13a/13=0/13

a= 0

Answer : No solution


I hope that's help !

PLEASE HELP ASAP Due in 1 day!!!
Helen [10]

Step-by-step explanation:

Q1 . (f+g)(x) = f(x) + g(x)

=4x-4 +2x^2 -3x

= 2x^2 + x -4

Q2. (f-g)(x) = f(x) - g(x)

= 2x^2−2 - (4x+1)

= 2x^2 -2 -4x -1

= 2x^2 - 4x -3

Q3. h(x)=3x−3 and g(x)=x^2+3

(h.g)(x) = h(x) × g(x)

= (3x-3) × (x^2 + 3)

=3x^3 -3x^2 + 9x -9

Q4.f(x)=x+4 and g(x)=x+6

(f/g)(x) = f(x) ÷ g(x)

= x+4 / x+6

the domain restriction is x>-6

x<-6

x doesn't equal (-6)
