g(x) = 3x + 2

y = 3x + 2

x = 3y + 2

3y = x - 2

y = x/3 - 2/3

inverse g(x) = (x - 2) / 3

g(x) = 4 - 5x

y = 4 - 5x

x = 4 - 5y

5y = 4 - x

y = 4/5 - x/5

inverse g(x) = (4 - x) / 5

Answer:

(x - 2)/3

(x - 4)/-5 or (-x + 4)/5

Step-by-step explanation:

this is an inverse function, and to solve an inverse function you would :

swap x and g(x) without bringing the x coefficient with it, just simply swap the variables. Then, solve for g(x), and that's it

the first question's answer is :

g(x) = 3x + 2

x = 3(g(x)) + 2

x - 2 = 3(g(x))

(x - 2)/3 = g(x)

the second one is:

g(x) = 4 - 5x

x = 4 - 5(g(x))

x - 4 = -5(g(x))

(x-4)/-5 = g(x)

a triangle has side cequals6 and angles equals startfraction pi over 4 endfraction and equals startfraction pi over 3 endfractio

Diano4ka-milaya [45]

Answer:

$a=\frac{12}{1+\sqrt{3}}$

Step-by-step explanation:

c=6

Angle A= π/4

Angle B= π/3

Angle C = π - (π/4+π/3)= 5π/12

We want to determine side A.

Using Sine Rule

$\frac{a}{Sin A}=\frac{c}{Sin C}$

$\frac{a}{Sin \frac{\pi}{4}}=\frac{6}{Sin \frac{5\pi}{12} }$

$a=\frac{6}{Sin \frac{5\pi}{12} } X Sin \frac{\pi}{4}$

$a=\frac{12}{1+\sqrt{3}}$

a=4.39

One soda and one taco costs $2.1. Two sodas and three tacos cost $5.15. Find the cost of a soda and a taco. Whoever answer this

DaniilM [7]

Answer:

Soda costs $1.15 and taco costs $0.95.

Step-by-step explanation:

x + y = 2.1

2x + 3y = 5.15

Multiply the first equation by -2 to eliminate x

-2x - 2y = -4.2

2x + 3y = 5.15

Add

y = 0.95

Find x with the original first equation

x + y = 2.1

x + 0.95 = 2.1

x = 2.1 - 0.95

x = 1.15

hope it helps :)

Evaluate the expression

fgiga [73]

Simplify the following:
2^3 (4×36/12 + 1/4)

4×36/12 = (4×36)/12:
2^3 ((4×36)/12 + 1/4)
2^3 = 2×2^2:
2×2^2 ((4×36)/12 + 1/4)
2^2 = 4:
2×4 ((4×36)/12 + 1/4)
2×4 = 8:
8 ((4×36)/12 + 1/4)
36/12 = (12×3)/12 = 3:
8 (4×3 + 1/4)
4×3 = 12:
8 (12 + 1/4)
Put 1/4 + 12 over the common denominator 4. 1/4 + 12 = 1/4 + (4×12)/4:
8 1/4 + (4×12)/4
4×12 = 48:
8 (1/4 + 48/4)
1/4 + 48/4 = (1 + 48)/4:
8 (1 + 48)/4
1 + 48 = 49:
8×49/4

8×49/4 = (8×49)/4:
(8×49)/4
8/4 = (4×2)/4 = 2:
2×49
2×49 = 98:
Answer: 98
