Write the equation of the line that passes through the points (-8,-5) (5,−8)
Nikolay [14]

Answer:

y=-3/13x-89/13

Step-by-step explanation:

m=y²-y¹/x²-x¹

m=(-8)-(-5)/5-(-8)

m=-3/13

y-y=m(x-x1)

y-(-8)=-3/13(x-5)

y+8= -3/13x+15/13

-8 -8

y=-3/13x-89/13

The area, A, of a triangle is one-half the product of the triangle's base and height. A = A = (12)(5) A = ( b+ h) A = A = (b·h)
polet [3.4K]

Answer:

A = (1/2) * b * h

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as obtuse, scalene, right angle, equilateral and isosceles triangle.

The area of a triangle is half the product of the base of the triangle and the triangle height. The area is given by the formula:

A = (1/2) * b * h

A = (1/2)bh  = 0.5bh

Where A is the area of the triangle, b is the bae of the triangle and h is the height of the triangle.

Ms. Wang is shopping for a new refrigerator. Brand A costs $569 and uses 635 kilowatt-hours per year. Brand B costs $647 and use
katen-ka-za [31]

Answer:

Savings on electricity per year by brand B = 114.3 - 104.76 = $9.54

Step-by-step explanation:

Ms. Wang is shopping for a new refrigerator. Brand A costs $569 and uses 635 kilowatt-hours per year. Brand B costs $647 and uses 582 kilowatt-hours per year.

Let's assume he buys brand B, so he already has a loss over the price of the commodity that is , loss = 647 - 569 =$78

Cost of electricity = $0.18

Now in the case of electricity,

spending on Brand A = 635\times 0.18 = $114.3

spending on Brand B = 582\times 0.18 = $104.76

Savings on electricity per year by brand B = 114.3 - 104.76 = $9.54

(x+1)-6(x+1)+8 how to factorise it?<br>​
sergij07 [2.7K]

Answer:

Step-by-step explanation:

If you have written the question correctly, then you don't need to factor it. You only need to remove the brackets.

x + 1 + 6x + 6 + 8

7x + 15 is your final answer.

However, I think the question is

(x + 1)^2 + 6(x + 1) + 8

Let y = x + 1

y^2 + 6y + 8

(y + 2)(y + 4)

(x + 1 + 2 ) ( x + 1 + 4)

(x + 3)(x + 5)
