3-3x6+2= -13 ? Is that correct

Answers

Answer 1

Answer: If x is a sign of multiplication, then 3-3x6+2 = -13 is incorrect.

The order of mathematical operation is PEMDAS.

1st operation to perform is the numbers inside a PARENTHESIS
2nd operation to perform is the number with EXPONENTS
3rd operation to perform is MULTIPLICATION
4th operation to perform is DIVISION
5th operation to perform is ADDITION
6th operation to perform is SUBTRACTION.

3-3x6+2 = -13

operation present are multipication, addition, and subtraction.

3-3x6+2 = -13

first, do multiplication : 3 - 18 + 2 = -13
second, do addition: 3 - 20 = -13
third, do subtraction: -17 = -13 ANSWERS ARE NOT EQUAL. THUS, INCORRECT.

Answer 2

Answer: No. Add before you subtract.
3x6 = 18 Multiply first
18+2=20 Addition
3-20= -17 Subtraction is last
-17 is answer

What is the slope of the line

Find an equation of the line that has the given slope and contains the given point. m=7/3 (1,6)

Answers

The point-slope form:

$y-y_1=m(x-x_1)$

We have the point (1, 6) and the slope m = 7/3. Substitute:

$y-6=(7)/(3)(x-1)$ use distributive property

$y-6=(7)/(3)x-(7)/(3)$ add 6 to both sides

$y=(7)/(3)x+(11)/(3)$ multiply both sides by 3

$3y=7x+11$ subtract 7x from both sides

$-7x+3y=11$ change the signs

$7x-3y=-11$

Answer:

point-slope form: $y-6=(7)/(3)(x-1)$

slope-intercept form: $y=(7)/(3)x+(11)/(3)$

standard form: $7x-3y=-11$

Explain why 83×93 is not the prime factorization of 7,719í

Answers

83×93 is not the prime factorization of 7,719 because 93 is not a prime number:

93 = 3×31

Therefore the prime factorization of 7,719 is 83×3×31.

Answer:

Because it isn't a prime number
