Answer:

y= 4 - 2/3 x, x= x

Step-by-step explanation: Substitute y=4 -2/3x  [2x=12-3 (4-2/3x)]

Simplify: [2x=2x]

For y = 4- 2/3x

Expressing y in terms of x: y= 4 -2/3x

So the solutions to the system of Equations are: y = 4 - 2/3 x, x = x

Rina8888 [55]
=4m - 17+ 3m - 11
combine like terms
=(4m + 3m) + (-17 - 11)
=7m - 28

This can be factored/simplified by dividing everything by 7
=7(m - 4)

Hope this helps! :)

2) f(x) = x² **<br> g(x)= 3x – 2<br> Find f(g(-4)
Usimov [2.4K]

Answer:

f(g( - 4)) = 196

Step-by-step explanation:

The functions are;

f(x) =  {x}^{2}

and

g(x) = 3x - 2

We want to find

f(g( - 4))

First we find g(-4) to get:

g( - 4) = 3 \times  - 4 - 2

g( - 4) =  - 12- 2

g( - 4) =  - 14

Now

f(g( - 4)) = f( - 14)

This implies that,

f(g( - 4)) = {( - 14)}^{2}

f(g( - 4)) = {( - 14)} \times  - 14

f(g( - 4)) = 196

What is the value of x?<br><br> 8x−10−4x=−12(12x−20)
madreJ [45]
What is the value of X?

Simplify:
8x - 10 - 4x =   - 12(12x - 20)


Simplify both sides:
8x - 10 - 4x =  - 12(12x -20)

8x +  - 10 +  - 4x  = (- 12)(12x) + ( -12)(- 20)
(Distribute:)
8x +  - 10 +  - 4x = 144x 240

(8x +  - 4x) + ( -10) =  - 144x + 240 (Combine Like Terms:)

4x +  - 10 =  - 144x + 240

4x - 10 =  - 144x + 240

Add - 144x to both sides:

4x - 10 +  144x =   - 144x + 240 + 144x

148x - 10 = 240


Add 10 to both sides:

148x - 10 + 10 = 240 + 10

148x = 250

Divide both sides by 148

148x/148 = 250/148

x = 125/74


Answer:  x = 125/74 (Decimal: 1.689189)



Hope that helps!!!!
