Mathematics

Alenkinab [10]3 years ago
8 0
8/-4
Divide as usual. Only difference is that since you are dividing by a negative number, you must include the negative sign in your answer.

-2 or -2/1. 8 and -4 can both be divided by -4. 8/-4 = -2. -4/-4 = 1. P.S. it doesn't matter where the negative sign is. Ex. it could be 2/-1 and still be the same.

Find the value of x. If necessary, round to the nearest tenth
Luden [163]

Answer:

8

Step-by-step explanation:

→ Use trigonometry to find x, we have no hypotenuse so we utilise the TOA formula

TOA = Tan = Opposite ÷ Adjacent

→ The opposite of the triangle is 8√3 and we want to find the adjacent of this triangle so we rearrange

Opposite ÷ Tan

→ Substitute in the values

8√3 ÷ tan(60) = 8

Solve with matrices. <br><br> 5x -3y = 18 and 2x + 7y = -1
muminat

We'll use Cramer's rule for 2 equations:

ax + by = e

cx + dy = f

5x -3y = 18 a=5 b=-3 e=18

2x + 7y = -1 c=2 d=7 f=-1

denominator determinant (dn) = (a * d) - (c * b) = 5 * 7 - (2 * -3) = 41

x = [(e * d) - (f * b)] / dn

[18 * 7 - (-1 * -3)] / 41 =

123 / 41 = 3

y = [(a * f) - (c * e)] / dn

= (5 * -1) -(2 * 18) / 41 =

-41 / 41 = -1

The sum of x and 16 is less than 32
OleMash [197]
I'm unsure of the question but this expression can be written as:
16 + x < 32.
This can be simplified to:
x < 16
