You add 27 + 27 then subtract 5 and your answer will be 49

X+5/2=27 ,so 49 plus 5 equals 54/2 equals 27  I got close to 54 and saw  divided by 2 =27 and then I had to figure the number 49 by 49+5 would equal 54 and 54 is the answer.

Answer:

{a}^{2}  -  {b}^{2}= {(80)}^{2}  -{(45)}^{2}  \\(a + b)(a - b) = (80 + 45)(80 - 45) \\  = 125 \times 35 = \boxed{ 4375}✓

What is the slope of (-1,6) and (2,3)?
LenKa [72]

Answer:

-1

Step-by-step explanation:

For a line joining two points (x1, y1) and (x2, y2), it's slope is given as:

\boxed{ \mathsf{slope =  \frac{ y_{2} -y  _{1}}{ x_{2} - x _{1}} }}

Here, the two points are (-1, 6) and (2, 3) in place of (x1, y1) and (x2, y2).

Solving for slope:

\implies \mathsf{ \frac{3 - 6}{2 - ( -1 )} }

\implies \mathsf{ \frac{ - 3}{2  + 1 } }

\implies \mathsf{ \frac{ - 3}{3 } }

\implies \mathsf{  - 1 }

Hence, the slope of the line joining the given points is <u>-1.</u>
