If the first term is n^2, then fisr make the equation =0, which would be n^2+7n+10. So what number multiplies to positive 10 and adds up to positive 7? 5 and 2. So factor the equation into (n+5)(n+2)=0. To make the equation 0, one of the parts have to be zero. The cases would be n=-5, -2

Write an equation of a line in point slope form that has a slope of -3 and passes through the point (3, -4).
Nesterboy [21]

1) Point-slope form

(y-y1)=m(x-x1)

m= - 3,

point (3,-4), so x1 = 3, y1 = - 4.

(y+4)= -3(x- 3)

2)Point-slope form

(y-y1)=m(x-x1)

m= - 3/4,

point (4,5), so x1 = 4, y1 = 5.

(y-5)= - 3/4(x-4)

If UW = 9x – 9, what is UW in units?
Tju [1.3M]
I will answer this question to the best of my ability, because you have not provided a value of x to plug in.


UW is always equal to 9x-9 or 9(x-1) whenever x is a real number.  By plugging in x, we can get the value.  For example, if x was 4, we plug in x, giving us 9*4-9=36-9=27 units or 9(4-1)=9(3)=27 units
Don't forget to include units when you complete your answer!

Hope this helps!  I did as much as I could!

Pls help due soon ty

The first table : y=4x
the second table: y=1.5x
the third table: y= 1.25x

if you want help on how to do it: plug each of those equations into the “desmos” graph! from looking at those table points (x,y) you can find which equation matches the table

for instance on table one: I put y=4x into desmos then looked at graph one, I chose the point (2,8) I went to 2 on the x axis and moved my finger up 8 and that point was directly on the line meaning that table matches the equation. be sure to also do the same thing with the other points to double check!
