You question isn't clear, but I assume that you are asking for the slop of a line parallel to y=-(5/4)(x)+7.
The line parallel would have a slop of -5/7 and the line perpendicular would have a slop of 5/7.
The difference between the two answers is the sign of the two slopes, one is positive the other is negative

Answer:

$x =320$

Step-by-step explanation:

Given

$x^2 + 200x = 166400$

Required

Find x

We have:

$x^2 + 200x = 166400$

Rewrite as:

$x^2 + 200x - 166400 = 0$

Expand

$x^2 + 520x - 320x - 166400 = 0$

Factorize

$x(x + 520) - 320(x + 520)= 0$

Factor out x + 520

$(x - 320) (x + 520)= 0$

Split

$x - 320 = 0\ or\ x + 520= 0$

Solve

$x = 320\ or\ x =- 520$

Side length must be positive;

So:

$x = 320$

If (a-b)²=7 and (a²+b²) =29.what is ab? Plssss asap

navik [9.2K]

Answer:

Given - (a-b)²=7

(a²+b²) =29

To find - ab

Solution -

( a- b) ^2 = 7

(a^2 + b^2) = 29

Expanding the bracket by using identity

a^2 + b^2 -2ab = 7

29 - 2ab = 7 (given a^2 + b^2 = 29 )

-2ab = 7 -29

-2ab = (-22)

ab = (-22) /(-2)

ab = 11
