Answer:

  • 16 - x ÷ 2
  • (16 - x) ÷ 2
  • 16 - (x ÷ 2).

Step-by-step explanation:

<u>Difference meaning (Math):</u>

  • Subtracting 2 numbers.

<u>If that's the meaning, equation should be:</u>

  • 16 - x ÷ 2.

<u>Remember:</u>

  • Parenthesis are sometimes required.
  • (16 - x) ÷ 2
  • 16 - (x ÷ 2).

Y² + 8y - 33 :

Break  the expression  into groups for formula ax²+ bx+c :

= (y²- 3y) + (11y - 33 )

Factor y from y² - 3y =>  y (y - 3)

Factor out 11 from  11 y - 33 => 11 (y - 3)

= y ( y- 3 ) + 11 ( y - 3 )

Factor  out common  term (y - 3 ) :

= ( y - 3 ) ( y + 11 )

hope this helps!

-2x+4y= 12 3x+7y= 18 last one greatly appreciated
LenaWriter [7]

Value of x is \frac{-6}{13}\\ and y is \frac{36}{13}

Solution set is (\frac{-6}{13}\\, \frac{36}{13})

Step-by-step explanation:

We need to solve the system of equations given.

-2x+4y=12\\3x+7y= 18

Solving

Let:

-2x+4y=12\,\,eq(1)\\3x+7y=18\,\,eq(2)

Multiply eq(1) by 3 and eq(2) by 2 and add both

-6x+12y=36\\6x+14y=36\\-------\\26y=72\\y=\frac{72}{26}\\y=\frac{36}{13}

Putting value of y in equation 1

-2x+4y=12\\-2x+4(\frac{36}{13})=12\\-2x+\frac{144}{13}=12\\-2x=12-\frac{144}{13}\\-2x=\frac{12*13-144}{13}\\-2x=\frac{12}{13}\\x=\frac{-6}{13}\\

So, value of x is \frac{-6}{13}\\ and y is \frac{36}{13}

Solution set is (\frac{-6}{13}\\, \frac{36}{13})

Answer with explanation will mark brainliest<br> for best response
Elina [12.6K]

Answer:

Angle B = 106.6 degrees

Step-by-step explanation:

b^2= a^2+c^2-2*a*c*cosB

9*9 = 4*4 + 7*7 - 2*7*4*cosB

81= 16+49-56cosB           Subtract 16 and 49 from both sides

16= -56cosB           Divide by -56 on both sides.

cosB= -16/56         Take the arccosine of both sides

B=arccos(-16/56)                    

B= 106.6
