The inverse of F(C)=9/5C+32

Nataliya [291]

F(C) = 9/5C + 32

I'll just change F(C) to y and 9/5C to 9/5x.
y = 9/5x + 32

inverse...

x = 9/5y + 32
9/5y = x - 32
y = 5/9x - 160/9

Sooooo
F(C) = 5/9C - 160/9

Answer:

The first number lets say is x

the second is y so

y=1/2x+8

x+1/2x+8=58

1 1/2x=50

x= 33 1/3

Soon-Jin sent out 48 invitations, this was 4/5 of all her invitations. How many invitations will she send out in total?

stepladder [879]

If 4/5 of the total is 48, the total can be found by dividing it by 4 and multiplying it by 5:
48/4 = 12
12*5 = 60.

Construct 3 linear equation starting with qiven solution z = 1/3

Andreyy89

Answer:

(a) $9z+2=5$

(b) $21z-11=-4$

(c) $4z=2-2z$

Step-by-step explanation:

We are required to construct 3 linear equations starting with the given solution z = 1/3.

<u>Equation 1</u>

<u /> $z=\frac{1}{3}$ <u />

Multiply both sides by 9

$9z=\frac{1}{3}\times 9\\9z=3$

Rewrite 3 as 5-2

9z=5-2

Add 2 to both sides

Our first equation is: $9z+2=5$

<u>Equation 2</u>

<u /> $z=\frac{1}{3}$ <u />

Multiply both sides by 21

$21z=\frac{1}{3}\times 21\\21z=7$

Rewrite 7 as 11-4

21z=11-4

Subtract 11 from both sides

Our second equation is: $21z-11=-4$

<u>Equation 3</u>

<u /> $z=\frac{1}{3}$ <u />

Multiply both sides by 6

$6z=\frac{1}{3}\times 6\\6z=2$

Rewrite 6z as 4z+2z

4z+2z=2

Subtract 2z from both sides

Our third equation is: $4z=2-2z$
