Sholpan [36]4 years ago
7 0

Answer:

x= -1, x=4

Step-by-step explanation:

5x²-15x-20

5x²-20x+5x-20=0

5x(x-4) +5(x-4)

(5x+5) (x-4) =0

5x=-5 or x=4

x= -5/5. or x=4

x= -1 or x=4

The lines can be defined by points on the line or by a given letter.

Responses:

1) Another name for the line <em>m</em> is the line \overleftrightarrow{CR}

2) Three points on the line <em>x</em> are C, E, and U

3) The common point of the line <em>x</em> and <em>n</em> is the intersection point <em>U</em>

4) Three points on the line <em>n</em> are U, L, and S

5) Three points on the line RS are R, F, and S

6) The common point of the line <em>n</em> and <em>y</em> is the intersection point <em>S</em>

7) Another name for the line CU is the line <em>x</em>

8) Another name for the line US is the line <em>n</em>

9) Three points on the line <em>y</em> are R, F, and S

10) Another name for the line CR is the line <em>m</em>

11) The common point of line US and RS is the point <em>S</em>

12) Three points that lie on the line <em>m</em> are C, A, and R

13) Another name for line <em>x</em> is line CU

14) The common point to the <em>m</em> and <em>y</em> is the point <em>R</em>

15) Another name for the line <em>n</em> is US

<h3>Which methods are used to find the correct responses?</h3>
  • A line extends infinitely in both direction and has no thickness, and it is the shortest distance between two points.

  • A line can be defined by two points that are on the line.

  • Two lines can intersect at one point.

Find the partial fraction decomposition of
Gwar [14]

\dfrac1{x(x-1)}=\dfrac ax+\dfrac b{x-1}

1=a(x-1)+bx

If x=0, then

1=-a\implies a=-1

If x=1, then

1=b

So we have

\dfrac1{x(x-1)}=\dfrac1{x-1}-\dfrac1x

I need help on #3 please
Ganezh [65]
The surface area of a shape is basically the sum of all the areas on a shape.

We’ve been given that the side is 17 mm.

An area of a square is A=s^2, in which s means side. So we do 17^2 to get the area of ONE of the squares.

Once we do that we get that the area of 1 square is 289.

Since there are 6 squares we need to multiply 289 by 6.

Therefore,

SA=1734mm^2

Graph a line with the indicated slope y-intercept slope =-5 and y-intercept (0,7)
mafiozo [28]
While we can't really graph it for you, this line has the equation y=-5x+7. We're given that (0, 7) is on the line, and another point on it is (2, -3). To graph the line, mark these two points on your graph, connect them with a segment, and extend this segment past both points.
