Klio2033 [76]

Roll 1: 1 number out of 6 total numbers = 1/6
Roll 2: 1 number out of 6 total numbers = 1/6
Roll 3: 1 number out of 6 total numbers = 1/6
Roll 4: 1 number out of 6 total numbers = 1/6

Roll 1 AND Roll 2 AND Roll 3 AND Roll 4
1/6 x 1/6 x 1/6 x 1/6 = 1/1296

Find the slope of the line that passes through (4, 10) and (2, 1).

Oksanka [162]

Answer:

slope = $\frac{9}{2}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (4, 10) and (x₂, y₂ ) = (2, 1)

m = $\frac{1-10}{2-4}$ = $\frac{-9}{-2}$ = $\frac{9}{2}$

Solve 3x²-x-2=0. Please show all work.

lorasvet [3.4K]

3x²-x-2=0

Δ=1+24=25 (Δ=b²-4ac)

x₁,₂= $\frac{1(+/-)\sqrt{25} }{6}$

x₁,₂= $\frac{1(+/-)5}{6}$

x1= $\frac{1+5}{6}$ =6/6=1

x2= $\frac{1-5}{6}$ = $\frac{-2}{3}$

so

x1=1

x2= $\frac{-2}{3}$
