PLEASE HELP

densk [106]

For this case we have that by definition, a function is of the form:

$y = f (x)$

So, we have the following system of equations:

$y = -6x + 2\\y = -2x + 4$

Equating the equations we have:

$-6x + 2 = -2x + 4$

Adding 2x to both sides of the equation:

$-6x + 2x + 2 = 4\\-4x + 2 = 4$

Subtracting 2 from both sides of the equation:

$-4x = 4-2\\-4x = 2$

Dividing between -4 on both sides of the equation:

$x = \frac {2} {- 4}\\x = - \frac {1} {2}$

Thus, the value of the variable "x" is -0.5.

Answer:

-0.5

Solve the equation<br>algebra 2<br><br>-6=3x-6y<br>4x=4+5x

Talja [164]

3x = 6y - 6
x = 2y - 2

4 ( 2y - 2 ) = 4 + 5 ( 2y - 2 )
8y - 8 = 4 + 10y - 10
2y = - 2
y = - 1

x = 2 ( - 1 ) - 2
x = - 4

joes family has compleated 60% of a road trip. if they have traveld 30 miles, how far is the full road trip?

Tems11 [23]

The full road trip is 50 miles.

Step-by-step explanation:

Given,

Distance traveled by Joe's family = 30 miles

This represents 60% of the total distance to be traveled.

Let,

x be the total distance.

60% of x = 30

$\frac{60}{100}*x=30\\0.6x=30$

Dividing both sides by 0.6

$\frac{0.6x}{0.6}=\frac{30}{0.6}\\x=50\ miles$

The full road trip is 50 miles.
