Find the value of x and y

Serhud [2]

1) 180° - 146° = 34
9х - 2 = 34
9х = 34 + 2
9х = 36
х = 36 : 9
х = 4
-------------

2) (9х - 2) + (6у + 44) = 180°
(9 * 4 - 2) + (6у + 44) = 180
(36 - 2) + (6у + 44) = 180
34 + 6у + 44 = 180
6у = 180 - 34 - 44
6у = 102
у = 102 : 6
у = 17
---------------

Which is the solution set to the given inequality |x+3|<12? x infinity(-15,9), x infinity {-15,9], x infinity (00,-15)U(9,00)

Viefleur [7K]

Answer:

Part 1) The solution set is (-15,∞) ∩ (-∞,9)=(-15,9)

Part 2) The ordered pair (1,3) is a solution of the system

Step-by-step explanation:

Part 1) we have

$\left|x+3\right|$

<u>First solution case Positive</u>

$+(x+3)$

$x$

$x$

The solution first case is the interval -------> (-∞,9)

<u>Second solution case Negative</u>

$-(x+3)$

$-x-3$

$-x$

$-x$ ------> Multiply by -1 both sides

$x>-15$

The solution second case is the interval -------> (-15,∞)

The solution set is equal to

(-15,∞) ∩ (-∞,9)=(-15,9)

Part 2) we have

$y>-2$ -------> inequality A

$x+y\leq 4$ -----> inequality B

we know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities

Verify each case

case a) (1,5)

Substitute the value of x and the value of y in the inequality and then compare

<u>Inequality A</u>

$5>-2$ ------> is true

<u>Inequality B</u>

$1+5\leq 4$

$6\leq 4$ -----> is not true

therefore

the ordered pair is not a solution

case b) (0,5)

Substitute the value of x and the value of y in the inequality and then compare

<u>Inequality A</u>

$5>-2$ ------> is true

<u>Inequality B</u>

$0+5\leq 4$

$5\leq 4$ -----> is not true

therefore

the ordered pair is not a solution

case c) (-2,-3)

Substitute the value of x and the value of y in the inequality and then compare

<u>Inequality A</u>

$-3>-2$ ------> is not true

therefore

the ordered pair is not a solution

case d) (1,3)

Substitute the value of x and the value of y in the inequality and then compare

<u>Inequality A</u>

$3>-2$ ------> is true

<u>Inequality B</u>

$1+3\leq 4$

$4\leq 4$ -----> is true

therefore

the ordered pair is a solution

Condense log₂ 4 + log₂ 5

yawa3891 [41]

Answer: $\log_2(20)$

Work Shown:

$\log_2(4) + \log_2(5)\\\\\log_2(4*5)\\\\\log_2(20)\\\\$

The rule used is $\log_{b}(\text{x}) + \log_{b}(\text{y}) = \log_{b}(\text{xy})$
