Absolute value- the
real number without regard to its sign.

Multiplication- *Negative* x *Negative* = Positive alwayss

Multiplication- *positive* + * Negative* = Negative always (same vise versa)

Division- *Negative* x *Negative* = Positive alwayss

Division - *positive* + * Negative* = Negative always ( same vise versa )

Additon- You do keep change change with this one ( example- -7 + 6 change this too- (-7 - (-6) = -1)
no matter weather its a positive or negative number KEEP THE SIGN OF THE BIGGER NUMBER!

Subtraction- You do keep change change with this one also ( example- 6 - -12 change this too- (6 + (12) = -18)
no matter weather its a positive or negative number KEEP THE SIGN OF THE BIGGER NUMBER!

Hope this helped

Please help me on this!!<br> 5n+17≥n–3≥–15+5n
DENIUS [597]

Answer:

-5 ≤ n ≤ 3

Step-by-step explanation:

Firstly we solve the equation two at a time;

5n + 17 ≥ n - 3

5n - n ≥ -3 - 17

4n ≥ -20

n ≥ -5

-5 ≤ n

n - 3 ≥ -15 + 5n

n - 5n ≥ -15 + 3

-4n ≥ -12

-n ≥ -3

n ≤ 3

Therefore,

5n+17 ≥ n–3 ≥ –15+5n, becomes

-5 ≤ n ≤ 3

Confusion...help please
kifflom [539]

Given:

In triangle KLM, KL = 123 cm and measure of angle K is 35 degrees.

To find:

The length of the side KM to the nearest tenth of a centimeter.

Solution:

In a right angle triangle,

\cos \theta =\dfrac{Base}{Hypotenuse}

In the given right triangle KLM,

\cos K=\dfrac{KM}{KL}

\cos (35^\circ)=\dfrac{KM}{123}

0.819152=\dfrac{KM}{123}

Multiply both sides by 123.

0.819152\times 123=KM

100.755696=KM

KM\approx 100.8

The measure of side KM is 100.8 cm.

Therefore, the correct option is (2).

Can someone help me with these 2
frosja888 [35]

Answer:

Step-by-step Yes it is, assuming we decide to use the Pythagorean Theorem to find the hypotenuse (10) it'll be possible considering the formula is c²=√a²+b²

(c being the longest side of the triangle)

a= 6 and b= 8

c² =√6² + 8²

c² = √100 square root of 100 equals 10

c= 10p explanation:
