What is the solution to a system of linear equations if the answer is -3=-3?
Vsevolod [243]

Answer:

No solution

Step-by-step explanation:

So the equation is saying that -3 is equal to 3. But that is false so it would make the system of linear equations be no solution. Which means that you are giving a number that is equal to another number when its not. For example, lets say that you are given 4=-20 well that would be no solution because those aren't equal. Now lets say you are given 20=20 that would be infinitely many solutions because the two numbers are equal to each other.

Hope this helps

Anastaziya [24]

Answer:

\displaystyle d = \sqrt{13}

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

<u>Algebra I</u>

  • Coordinates (x, y)

<u>Algebra II</u>

  • Distance Formula: \displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (4, -8)

Point (7, -10)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>

  1. Substitute in points [DF]:                     \displaystyle d = \sqrt{(7-4)^2+(-10+8)^2}
  2. (Parenthesis) Subtract/Add:                \displaystyle d = \sqrt{(3)^2+(-2)^2}
  3. [√Radical] Exponents:                         \displaystyle d = \sqrt{9+4}
  4. [√Radical] Add:                                    \displaystyle d = \sqrt{13}

Rasek [7]

Answer:

10.875 total, 1.5 times each are below.

Step-by-step explanation:

1.5 (1 1/2) x 1.5 = 2.25

0.5 (2/4) x 1.5 = 0.75

0.125 (1/8) x 1.5 = 1.875

4 x 1.5 = 6

2.25 + 0.75 + 1.875 + 6 = 10.875 total

I need the answer to the clue/message not the MATH which requires you to do math
iVinArrow [24]

Answer:

HE WAS LAST SEEN HEADING NORTH

Step-by-step explanation:

360: A

25×10×40 = 10000: I

(15×10.5×20)/450 = 7: W

(35×16×50)/800 = 35: S

3168/(22×9) = 16: N

cuberoot(64) = 4: R

6.5×15×8.5 = 828.75: G

4×2×3 = 24: E

3885/(18.5×15) = 14: H

3³ = 27: T

½ (7×9×12) = 378: L

30×20×11 = 6600: D

3600/(2×4÷5) = 90: O
