Answer:

126

Step-by-step explanation:

Row 1: 30+0*4

Row 2: 30+1*4

Row 3: 30+2*4

...

The list goes on. Do you see a pattern here? If we call the row number as r, the formula is 30+(r-1)*4. In the 25th row, the r is 25. So in the formula, it is 30+(25-1)*4=30+24*4=126.

I hope that helped.

Which of these is a point-slope equation of the line that is perpendicular to y-25=2(x-10) and passes through (-3,7)
OLEGan [10]
Y = 2x +13

We know the slope to be 2 because lines that are parallel have the same slope. Then we can solve using slope-intercept form and  the known point. 

y = mx + b ----> Input known values
7 = (2)(-3) + b ---> Multiple
7 = -6 + b ----> Subtract 3 from both sides
13 = b

Now we can use the y-intercept found and the slope to write the equation above.

I hope this helps you



1.k^2+5k-6=0


a=1


b=5


c= -6


disctirminant =b^2-4ac


disctirminant =5^2-4.1. (-6)


disctirminant =49


x1= -(5)+ square root of 49/2.1



x1=-5+7/2


x1=1



x2= -5- square root of 49/2.1


x2= -5-7/2


x2= -6
