Answer:

(2/3)y - (8/3) = x For the first one maybe?

Step-by-step explanation:

1. y = (3/2) x + 4

y - 4 = (3/2) x

(2/3)y - (8/3) = x

2. If output is 2, f(x) = 2.

So, 2 = (3/2) x + 4

-2 = (3/2) x

-4 = 3x

x = -3/4

A grade has 81 girls and 72 boys. The grade is split into groups that have the same ratio of girls to boys as the whole grade. H

Delicious77 [7]

There will be 18 girls in a group of 16 boys.

you divide 72 by 16 and get 4.5.
then you divide 81 by 4.5 and get 18.

That is how you get 18 girls in a group of 16 boys.

Hope that helped.

Plzzz Helpp with this!!!!

Travka [436]

f(g(11)) = -6

Solution:

Given data:

$f(x)=x^{2}-6 x+3$

$g(x)=\sqrt{x-2}$

To find f(g(11)):

Substitute x = 11 in g(x).

$g(11)=\sqrt{11-2}$

$=\sqrt{9}$

$g(11)=3$

Substitute g(11) = 3 in f(g(11)).

$f(g(11))=f(3)$

$f(x)=x^{2}-6 x+3$

$f(3)=3^{2}-6 (3)+3$

$f(3)=9-18+3$

$f(3)=-6$

$f(g(11))=f(3)$

= -6

Hence f(g(11)) = -6.

A. 2 cm B. 2√2 cm C. 4 cm D. 4√2 cm

algol [13]

Answer:

.D. 4√2 cm

Step-by-step explanation:

With reference angle 45°

base (b) = 4 cm

hypotenuse (h) = AC

Now

Cos 45° = b /h

1/√2 = 4 / AC

AC = 4√2 cm
