Answer:

y=5x+42

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(7-(-3))/(-7-(-9))

m=(7+3)/(-7+9)

m=10/2

m=5

y-y1=m(x-x1)

y-(-3)=5(x-(-9))

y+3=5(x+9)

y=5x+45-3

y=5x+42

Marguerite is building a box from strips of wood.she needs 78 pieces of wood that are each 29 centimeters long.the wood comes in

dolphi86 [110]

Each strip is 29 cm

------------------------------------------------------
Change the m to cm
------------------------------------------------------
6 m = 600 cm

------------------------------------------------------
Find the number of strips for 1 6m-board
------------------------------------------------------
Find the number of strips that can be cut from the 6m board.

600 ÷ 29 = 20 pieces remainder 20cm

So we can only cut 20 pieces of 29 strips from one 6m board.

------------------------------------------------------
Find number of boards needed
------------------------------------------------------
70 ÷ 20 = 3.5

We need 3.5 of the 6m boards.

Since she can't have half a board, she has to buy 4 pieces of the board.

------------------------------------------------------
Answer: 4 pieces of the 6m board.

Solve for x: 4 over x plus 4 over quantity x squared minus 9 equals 3 over quantity x minus 3

dezoksy [38]

Answer:

Step-by-step explanation:

4/x + 4/(x²-9) = 3/(x - 3)

4 / x + 4 / [( x - 3) ( x + 3 )] = 3 / ( x - 3 ) / * x ( x - 3 ) ( x + 3 )

Restrictions : x ≠ 0, x ≠ - 3 , x ≠ 3;

4 ( x + 3 ) ( x - 3 ) + 4 x = 3 x ( x + 3 )

4 ( x² - 9 ) + 4 x = 3 x² + 9 x

4 x² - 36 + 4 x - 3 x² - 9 x = 0

x² - 5 x - 36 = 0

x² - 9 x + 4 x - 36 = 0

x ( x - 9 ) + 4 ( x - 9 ) = 0

( x - 9 ) ( x + 4 ) = 0

x - 9 = 0, or : x + 4 = 0

Answer:

x = 9, x = - 4
