Answer: All real numbers
Step-by-step explanation:
−2(x + 3) = −2(x + 1) − 4
-2x -6 = -2x -2 -4
-2x -6 = -2x -6
-2x = -2x
The output of the the equation 3+7+8=212473 i this we first multiply the 1st and the 2nd number then we multiply the 1st and the 3rd number,then we add the result of the two output and deduct with the last number (i.e 8) and then we reverse the output to get the whole answer.
Step-by-step explanation:
<u>Step 1</u>
We have been given that
3+5+6 = 153058
5+5+6 = 253094
5+4+7 = 202874
2+6+9 = 125455
3+7+8=212473
<u></u>
<u>Step 2</u>
1. Multiply 1st and 2nd number (ignore the signs of summation) and the result makes the first two digits of the resultant 6-digit number.
(i.e. 3*7=21)
<u>Step 3</u>
Multiply 1st and 3rd number, which makes the following two digits
For example :( 3*8=24)
<u>Step 4</u>
Now add the two results you got from the multiplications step 1 and 2
i.e. 21+24=45
<u>Step 5</u>
Now subtract the result obtained in step 4 from the 3rd number on the left side of the equation.
i.e. 45-8=37
<u>Step 6</u>
Now switch places of the digits, obtained in the result and there you have it, the last two digits. (i.e. 73)
<u>Step 7</u>
<u></u>
<u>so the final answer is </u>3+7+8=212473
Answer:
B
Step-by-step explanation:
-2x+4y=1
3x-6y=9
To find x
First, change the second equation to slope equation.
Next, you will get -6y=3x+ 9 and divide everything by -6. -6y/-6 = 3x/-6 + 9/-6
Then, simplify and you will get y= -1/2x-3/2.
After that, replace the y=-1/2x-3/2 from the second equation and replace the y with (-1/2x-3/2).
Then, use the -2x from the first equation, add 4 and put one of the parentheses after 4 and put down -1/2x-3/2, put another parentheses after -1/2x-3/2, and put the equal sign (=) and after the equal sign, put 1.
Lastly, your equation will look like -2x+ 4(-1/2x-3/2) = 1. Do -2x + 4 and then, multiply the 4 with (-1/2x-3/2). The equation with look like -2x+-4/2x-12/2 = 1.
Simplify the fractions (-4/2x and 12/2) and you will get -2x and 6.
The equation will look like -2x+-2x-6=1 and then, add 6 to the left side of = and the right side of =.
Add -2x and -2x together, it will get you to -4x=-7, and divide -4 on each side.
It will look like this -4x/-4=7/-4. Your answer for x is -1 3/4 or -1.75. I'd rather go with the decimal instead of fraction.
To find y
First, use the second equation.
Next, write down 3 and replace the x with -7/4 in parentheses because I'd rather use an improper fraction instead of a decimal. After the parentheses, subtract the -6y and put =9.
Then, the equation will look like 3/1(-7/4) -6y = 9. Distribute by multiplying 3/1 and -7/4 which will get you to -21/4.
After that, multiply 4/1 to the entire equation. It will look like 4/1(-21/4 -6y = 9). The equation will look like -21 -24y= 36. Add the -21 to both sides of the equation. You will get to -24y = 57. Divide -24y by -24 and 57 by -24. It will look like -24y/-24 = 57/-24. You will get the answer of -57/24, but you have to simplify the answer. If you divide by 3 to the numerator and denominator, you will get -19/8. However, I do prefer the decimal answer, which is -2.37.
Lastly, put the ordered pair together, since x= -1.75 and y= -2.37. Your answer will start with parentheses and then x and end with y and another parentheses, but in between x and y there's always a comma. So, your official answer is (-1.75, -2.37).
