Step-by-step explanation:

I cannot read the initial expression without doubt, but I just guess it is 3×sqrt(8).

that would make it : sqrt(9×8) = sqrt(72).

A is correct : sqrt(9)×sqrt(8) = sqrt(9×8) = sqrt(72).

B is correct : sqrt(6)×sqrt(12) = sqrt(6×12) = sqrt(72).

C is NOT correct : sqrt(6)×sqrt(24) = sqrt(6×24) = sqrt(144) = 12

D is correct : sqrt(3)×sqrt(24) = sqrt(3×24) = sqrt(72)

E is NOT correct : 72 is NOT sqrt(72)

F is NOT correct : sqrt(3)×sqrt(12) = sqrt(3×12) = sqrt(36) = 6

Find the Value of X.

ArbitrLikvidat [17]

Answer:

Step-by-step explanation:

∠ TUL + ∠ LUV = ∠ TUV , substitute values

x + 16 + 11x = 172 , that is

12x + 16 = 172 ( subtract 16 from both sides )

12x = 156 ( divide both sides by 12 )

x = 13 → C

Choose the correct equation in point-slope form for the line that passes through the point with the given slope. (2, -1), m= -3

Inga [223]

Y - y1 = m(x - x1)
slope(m) = -3
(2,-1)...x1 = 2 and y1 = -1
now we sub....pay attention to ur signs
y - (-1) = -3(x - 2)....not done yet
y + 1 = -3(x - 2) <===

A coordinate plane with a line passing through (0, negative 4) and (2, 0). What is the equation of the graphed line written in s

Hoochie [10]

Answer:

d) The equation of the line passing through the points

$y = \frac{-x}{2} - 4$

Step-by-step explanation:

Step(i):-

Given points are ( 0, -4) and (2 ,0)

slope of the line

$m = \frac{y_{2}- y_{1} }{x_{2}- x_{1} } = \frac{2-0}{0-4} = \frac{-2}{4}= \frac{-1}{2}$

Step(ii):-

The equation of the line passing through the point ( 0,-4) and having slope

$m = \frac{-1}{2}$

$y - y_{1} = m ( x - x_{1} )$

$y - (-4) = \frac{-1}{2} ( x - 0 )$

2 ( y +4) = -x

2 y + 8 = -x

2 y = - x - 8

$y = \frac{-x}{2} - \frac{8}{2}$

$y = \frac{-x}{2} - 4$

Final answer:-

The equation of the line passing through the points

$y = \frac{-x}{2} - 4$
