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

Find the length of side xz give your answers to 3 significant figures

aleksandrvk [35]

Answer:

XZ ≈ 14.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos29° = $\frac{adjacent}{hypotenuse}$ = $\frac{ZY}{XZ}$ = $\frac{12.6}{XZ}$

Multiply both sides by XZ

XZ × cos29° = 12.6 ( divide both sides by cos29° )

XZ = $\frac{12.6}{cos29}$ ≈ 14. 4 ( to 3 sig. figs )

I can’t figure out the solution I think it is y < -10

Hey there!

<em>With negatives ( $-$ ) you have to switch your symbol to the other way</em>
$\bold{\frac{y}{-2}\leq5}$
Firstly, substitute the $\bold{y\ value }$ as an invisible 1
So, now we have to flip the equation around
$\bold{\frac{-1}{2}y\leq5}$
We have to $\bold{multiply}$ by $\bold{-2}$ on each of your sides
$\bold{-2\times\frac{-1}{2}\leq-2\times5}$
$\bold{Cancel \ out:2\times\frac{-1}{2}y \ because \ it \ equal \ 1}$
$\bold{Keep: -2\times5 \ because \ it \ helps \ us \ find \ our \ answer}$
$\bold{-2\times5=-10}$
$\boxed{\boxed{\bold{Answer:y\geq-10}}}\checkmark$

Good luck on your assignment and enjoy your day!
