What is the equation for the line that passes through the points (-2,1) and (1,-11)
givi [52]

Answer:

y=4x+7

Step-by-step

(-2,1) and (1,-11)

1)Rule you should use is run over rise aka slope

y²-y^1=

x^2-x^1=

(-11)-1=12

1-(-2)=3

12/3=4

slope =4

2)Rule of point slope intercept

y - y1 = m(x - x1)

y+1=4(x+2)

y+1=4x+8

   -1     -1

y=4x+7

!!!The volume of the given figure is______!!!!
choli [55]

Answer:

284.837734 ft^3 rounded up to 284.84 ft^3

Step-by-step explanation:

Cylinder Volume: pi*r^2h

pi*4^2*4=201.06193

Cone Volume: pi*r^2*(h/3)

pi*4^2*(5/3)=83.7758041

201.06193+83.7758041=284.837734

284.837734 ft^3

A2-b2 ÷5a-5b factorise​
katrin2010 [14]

Answer:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "b2"   was replaced by   "b^2".  1 more similar replacement(s).

STEP

1

:

           5a + 5b

Simplify   ———————

           a2 - b2

STEP

2

:

Pulling out like terms

2.1     Pull out like factors :

  5a + 5b  =   5 • (a + b)  

Trying to factor as a Difference of Squares:

2.2      Factoring:  a2 - b2  

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check :  a2  is the square of  a1  

Check :  b2  is the square of  b1  

Factorization is :       (a + b)  •  (a - b)  

Canceling Out :

2.3    Cancel out  (a + b)  which appears on both sides of the fraction line.

Final result :

   5 / a -b
