Albert´s ftather age=x
Albert age=y

We suggest this system of equations:
y=x-24
x+8=2(y+8)

we solve this system of equation by substitution method.

x+8=2[(x-24)+8]
x+8=2(x-16)
x+8=2x-32
x-2x=-32-8
-x=-40
x=40

y=x-24
y=40-24
y=16

Answer: Albert´s father is 40 years old, and Albert is 16 years old.

PLEASE HELP ME ASAP!
romanna [79]

Answer:

x =- 3 and y = -7

Step-by-step explanation:

2X-2Y=-8

X=2y + 11

We need to isolate both X and Y in both equations

so

2x-2y=-8

(add 2y to both sides)

2x=-8+ 2y

(divide both sides by 2)

x=-4+y and x=2y+11

because <u>both of these equations are the same </u>we can put them together

4+y=2y+11

(subtract y)

4=y+11

(subtract 11)

-7=y

so y = -7

then to find x you just need to plug in y to one of the equations

x=2(-7) + 11

x= -14 +11

x = -3

What is the inverse of f(x)=4x+5?
cestrela7 [59]

Answer:

C

Step-by-step explanation:

swap y and x in the function. that is

x = f(y)

we get x=4y+5

<em>S</em><em>o</em><em>l</em><em>v</em><em>e </em><em>for </em><em>y</em>

(x-5)/4=y

f ^{ - 1}(x) =  \frac{1}{4}  (x - 5)
