Its not 3/-2 because its still negative; when u flip a reciprocal it is either positive or negative! if its already negative then your reciprocal has to be positive so the answer to your question would be 3/2

$\sf{\implies Range = Highest \: - lowest }$

→ Range of Lewistown = 74 - 64

→ Range of Lewistown = 10 .

→ Range of Hamersville = 71 - 55

→ Range of Hamersville = 16 .

☆ Range of Hamersville - Range of Lewistown

→ 16 - 10

→ 6

Answer → The range for Hamersville is 6 more than the range for Lewistown .

Find the slope, distance and midpoint between

Dovator [93]

Answer:

Slope- 4

Distance- 12.4

Midpoint- (6,8)

Step-by-step explanation:

Slope- $\frac{y2-y1}{x2-x1}$

$\frac{2-14}{4-7} =\frac{-12}{-3}=4$

Distance- $d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}$

$d = \sqrt{(4 - 7)^2 + (2-14)^2}$

$d = \sqrt{-3^2 + -12^2}$ $d = \sqrt{144+9}=\sqrt{153}$

$\sqrt{153} = 12.4$

Midpoint- $\frac{x1+x2}{2} ,\frac{y1+y2}{2}$

$\frac{7+4}{2} =\frac{12}{2} = 6=x$

$\frac{14+2}{2} = \frac{16}{2} = 8 = y$

(6,8)

What are equivalent expressions for 6(y-1) and 64x+80

snow_tiger [21]

To find equivalent expressions, distribute the first one and factor the second one.

$6(y-1) \\ (6*y)+(6*-1) \\ 6y-6 \\ \\ 6(y-1)=6y-6 \\ \\ 64x+80 \\ 16( \frac{64}{16}x+ \frac{80}{16}) \\ 16(4x+5) \\ \\ 64x+80=16(4x+5)$

Cot²3x - 3cot3x +2 = 0 cotx = t what equation for t

kumpel [21]

Answer:

Step-by-step explanation:

cot²(3x)=y

y²-3y+2=0

y²-y-2y+2=0

y(y-1)-2(y-1)=0

(y-1)(y-2)=0

y=1,y=2

cot3x=1

tan 3x=1=tan (π/4)=tan (nπ+π/4)

3x=nπ+π/4=(4nπ+π)/4=(4n+1)π/4

x=(4nπ+1)π/12,n is an integer.

cot 3x=2

tan 3x=1/2

3x=tan^{-1}(1/2)≈26.57°+360n

x≈8.86°+120n
