How do you write a system of equations with the solution (-1,-1)? NEED HELP WILL MARK BRAINLIEST!!!

Step-by-step explanation:

7k² + 3k - 10

= 7k² + ( 10 - 7 ) k - 10

= 7k² + 10k - 7k - 10

= k( 7k + 10 ) - 1( 7k + 10)

= ( 7k + 10) ( k - 1)

Hope it will help :)

Answer:

Step-by-step explanation:

Use the Pythagorean Theorem to determine the roots

k = 1,-10/7

7k^2+3k-10 = 7(k-1)(k+10/7) = (k-1)(7k+10)

Answer: y=12 x =9

Step-by-step explanation:

In a parallelogram the diagonals bisect each other making them equal.

this means 2y + 6 = 30

we can rearrange this as 30 - 6 = 2y

24 = 2y  therefore y = 12

3x - 3 = 24

We can rearrange this as 24 + 3 = 3x

3x = 27

27 / 3 = 9

x = 9

After graphing  x⁵ – 4x³ + x² + 2, we have

local minimums : (1.46, -1.68)

increasing : 1.46 < x < -1.63

decreasing : -1.63 < x < 1.46

In discrete mathematics, and mοre specifically in graph theοry, a graph is a structure amοunting tο a set οf οbjects in which sοme pairs οf the οbjects are in sοme sense "related". The οbjects cοrrespοnd tο mathematical abstractiοns called vertices (alsο called nοdes οr pοints) and each οf the related pairs οf vertices is called an edge (alsο called link οr line).

Typically, a graph is depicted in diagrammatic fοrm as a set οf dοts οr circles fοr the vertices, jοined by lines οr curves fοr the edges. Graphs are οne οf the οbjects οf study in discrete mathematics.

ITS IS D (4,-3)

Step-by-step explanation:

Ap ex

The coordinates of M is M’(4,-3).

Rotation means the circular movement of an object around a center. It is possible to rotate different shapes by an angle around the center point.

Given:

LMNP is rotated 90° clockwise around the origin.

If we rotate the figure in LMNP  about 90 degrees then the coordinates will change into

(x, y)  to (y, -x).

As, x= 3, y=4

Hence, the coordinates of M is M’(4,-3).

Answer:

Step-by-step explanation:

-40x + 8y = -24

 3x  -  8y = 24

-37x = 0

x = 0

0 + y = -3

y = -3

(0, -3)

Answer:

I will show you how to solve for x and y.

Step-by-step explanation:

-5x + y = -3

3x - 8y = 24

You can isolate y in the first equation, and substitute that into the second equation.

so to isolate y in -5x + y = -3, you would add 5x to both sides

this gives you y = 5x - 3

Then substitute this y into the equation below.

3x - 8(5x-3) = 24     (this way, the y variable disappears)

then distribute the 8 into the bracket

3x - 40x + 24 = 24

combine the variables

-37x + 24 = 24

isolate x by moving the constants to one side

-37x = 0

so x = 0

I am not sure if you want the rest, but here it is.

substitute x = 0 into one of the equations.

-5x + y = -3

-5(0) + y = -3

y = -3

Explanation:

You move the decimal point two spots to the left to go from 2.85% to 0.0285

Or you can think of it like this:
