2x − 3y − z
 x = −2,
 y = 3,
 z = −2
What we must do is replace the values given in the equation. We have then replacing:
 2*(-2) - 3*(3) - (-2) = -11
The answer is -11

Simplify Will give brainiest to person who solves all the problems in picture.

Reika [66]

Answer:

$\sqrt{10+4\sqrt{6 }$ = 4.44948

or = $\sqrt{6} + 2$

step by step...solving

10 + 4 $\sqrt{6}$

add/subtract $\sqrt{6}$ ² = 6

=10 + 4 $\sqrt{6}$ + $\sqrt{6}$ ² - 6

Refine

= $\sqrt{6}$ ² + 4 $\sqrt{6}$ + 4

rewrite ↑ as $\sqrt{6}$ ² + 2 $\sqrt{6}$ * 2 + 2²

apply Perfect Square Formula (a + b)² = a² + 2ab +²

a = $\sqrt{6}$ , b=2

= ( $\sqrt{6}$ + 2)²

= $\sqrt \sqrt({6}+ 2)$ 2square

(the 2 square would not fit like i wanted it to)

apply radical rule $\sqrt[n]{a^{n} } = a$ , assuming a ≥ 0

= $\sqrt{6} + 2$

posting others as picture (have an account with Symbolab to help me as well. Just taking too long to type in the step by step if you need it. all pictures have the decimal result.

A 40 of foxes in a wildlife preserve quadruples in size every 13 years. The function y=40•4^4, where x is the number of 13-year

SashulF [63]

Answer:

640 foxes

Step-by-step explanation:

The actual formula is $y = 40 * 4^{x}$

Now that we have the real formula we would need to find out how many 13 year periods exist in the 26 years that are being used in the question. We calculate this by simply dividing 26 by 13.

26 / 13 = 2 periods

Therefore, now that we know there are 2 periods of 13 years in the 26-year span, we plug this value into the formula and solve for y...

$y = 40 * 4^{x}$

$y = 40 * 4^{2}$
