Use the quadratic formula and plug in the coefficients

3x - 9 {x}^{2} = - 10 \\ - 9 {x}^{2} + 3x + 10 = 0 \\ b = 3 \\ a = - 9 \\ c = 10 \\ - \frac{3 + \sqrt{ {3}^{2} - 4( - 9)(10) } }{2( - 9)} \\ \frac{ - 3 + \sqrt{9 + 360} }{ - 18} \\ \frac{ - 3 + 3 \sqrt{41} }{{ - 18} } \\ \frac{ - 1 + \sqrt{41} }{ - 6}

I wasn't able to the plus or minus sign in so I just used the plus sign you can look up the quadratic formula online

Let w = 4. Enter >, <, or = to compare the expressions. 3w² + 1 10w + 8
Svetach [21]

Answer: ≥ without the line on the bottom.

Step-by-step explanation:

I am assuming the expression you are talking about are

3w^{2} +1 and 10w+8.

If we were to replace w with 4 and calculate, we will find the answer:

3*4^{2}  +1=3*16+1=48+1=49

10*4+8=40+8=48

Since the first expression, 3w^{2} +1, is bigger than the second expression, the correct symbol to use is ≥ without the line on the bottom.

the formula y-y=m(x-x) is the point -slope from of the equation of a line where m is the slope of the line and (x,y) and ( x,y)
hodyreva [135]
(4,-2)(5,0)
slope(m) = (0 - (-2) / (5 - 4) = 2/1 = 2
there is going to be 2 possible answers...

y - y1 = m(x - x1)
now we sub

using points (4,-2)..... y -(-2) = 2(x - 4) =
y + 2 = 2(x - 4) <==

using points (5,0)....y - 0 = 2(x - 5) <==
