Step-by-step explanation:

Rounding to nearest tenth:

i) if number in 100th place is 5,6,7,8 or 9, then add 1 to number in the tenth place and after adding remove all the digits right to it.

EG: 4.567 = 4.6

ii) if number in 100th place is 0,1,2,3 or 4, then write down number in the tenth place as it is and then remove all the digits right to it.

Eg: 4.523 = 4.5

a) 0.32 = 0.3 (b) 3.87 = 3.9 (c)0.709 = 0.7

d) 12.75 = 12.8 (d)12.745 = 12.8 e) 645.059 = 645.1

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

$\left|x+3\right|$

First solution case Positive

$+(x+3)$

$x$

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

Second solution case Negative

$-(x+3)$

$-x-3$

$-x$

$-x$ ------> 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

Inequality A

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

Inequality B

$1+5\leq 4$

$6\leq 4$ -----> 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

Inequality A

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

Inequality B

$0+5\leq 4$

$5\leq 4$ -----> 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

Inequality A

$-3>-2$ ------> 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

Inequality A

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

Inequality B

$1+3\leq 4$

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

therefore

the ordered pair is a solution
