Answer:

130z-3

Step-by-step explanation:

Break down the equation:

(9z^{2}-4)=

9z * 9z= 81z

You can't subtract 4, so I left it at (81z- 4)

(7z^{2}+ 1)=

7z * 7z= 49z

You can't add 1, so I left it at (49z+ 1)

Then Solve:

You can add 81z and 49z.

81z+49z= 130z

-4+1= -3

Hope this helps!

Line n passes through points (7, 12) and (4, 15). What is the slope of a line that
vitfil [10]
So anytime we have a slope and want to find the slope of a perpendicular line, we just have to remember a perpendicular line's slope is the negative reciprocal (reciprocal means flip the fraction). So if we had a slope of 3/4, the slope perpendicular to it would be - 4/3.


First we need to find our slope, to do this we take the change in y over the change in x like so:

(15-12)/(4-7) = - 3/4

The slope perpendicular to this is 4/3.

Ahmed buys a house worth 268,000 pounds and its value rises at a compound rate of x% per year.
levacccp [35]
It would be .546% increase per year. You divide 292662.70 by 268000 and get 1.092025 and then divide by 2 for the years and get .546. Hope this helps

What is the solution to the equation x2 +6x=40
eimsori [14]

Answer:

x=10  x=-4

Step-by-step explanation:

x^2 +6x = 40

subtract 40 from each side

x^2 +6x -40 = 0

what numbers multiply to -40 and add to 6

-10 *4 = -40       -10 +4 = 6


(x-10) (x+4) = 0

using the zero product property

x-10 = 0  x+4 =0

x=10      x=-4
