Which statement is true about the equation? 3y-6x=-3

Mekhanik [1.2K]

<span>B.When x=-4, y=-9 and when x=2, y=3.

</span><span>3y-6x=-3
3(-9) - 6(-4)= -3
-27 +24 =-3
-3 = -3

</span>
<span>3y-6x=-3
3(3) -6 (2) = -3
9 - 12 = -3
-3 = -3

What is 3/2 x + 30 degrees

jekas [21]

Sum of internal angles of any triangle = 180∘

∴x + 2x + 3x = 180∘
∴6x = 180∘
∴ x = 30∘

So the angles are: 30∘, 60∘ and 90∘

<span>(3,5),
(5,8),
(6,13)
------
(14,26)/3

then use the point slope form of a line to find equation of line

</span> $y-y_1=m(x-x_1)
\\y - \frac{26}{3} = 2.5(x- \frac{14}{3})
\\y - \frac{26}{3} = \frac{5}{2} (x- \frac{14}{3})
\\y - \frac{26}{3} = \frac{5}{2} x- \frac{5}{2}\times\frac{14}{3}
\\y - \frac{26}{3} = \frac{5}{2} x- \frac{35}{3}
\\6y-52=15x-70
\\15x-6y-18=0$

What is the sum of the next two terms in the sequence: -3, -1, 3, 9, 17

Korvikt [17]

Answer: 66 because you are adding 2 then 4 then 6 then 8 then 10 then 12 therefore 17+10= 27, and 27+12= 39 and 39+27 equals 66
