What is the equation of the line that is perpendicular to 3x -6y =2 and contains the point (-2,--5)​
julsineya [31]

Answer:

y=-2x-12

Step-by-step explanation:

first, putt 3x-6y=2 in standard form:

subtract 3x from both sides: -6y=-3x+2

divide both sides by -6 to isolate y: y=1/2x-1/3

if the other line is perpendicular to this, you must find the slope by finding the opposite reciprocal of 1/2x: -2

now we have 2 points a slope, so we use the point-slope formula: y-y1=m(x-x1)

y+2=-2(x+5)

Use the distributive property: y+2=-2x-10

subtract 2 for both sides to isolate y: y=-2x-12

What’s the answer to this equation?
Tresset [83]

Answer:

Part A) The graph in the attached figure

Part B) see the explanation

Step-by-step explanation:

Part A) Graph the function

we have the quadratic function

y=3x^2-12x-36

This is a vertical parabola open upward

The vertex is a minimum

using a graphing tool

The graph in the attached figure

Part B) What are the values of a, b and c?

we know that

The values of a and b represent the x-intercepts of the quadratic equation

The x-intercepts are

(-2,0) and (6,0)

so

a=-2\\b=6

Find the value of c

we know that

The x-coordinate of the vertex in a vertical parabola is equal to the midpoint of the roots

so

The value of c is equal to

c=\frac{a+b}{2}

substitute the given values

c=\frac{-2+6}{2}=2

see the attached figure

You want to put a 4 inch thick layer of topsoil for a new 28 ft by 14 ft garden. The dirt store sells by the cubic yards. How ma
Digiron [165]

Answer:

Step-by-step explanation:

1 yard = 3 feet = 36 in

so 1 in = 1/36 yard,  1 ft = 1/3 yard.

The volume of the layer of the topsoil, is:

4 in * 28 ft * 14 ft = 4 *(1/36)*23*(1/3)*17*(1/3)  yard cubed =

(4*28*14)/(36*3*3)= 1955/324=

The store only sells increments of 1/4 = 0.25 cubic yards.

we need 6.034/0.25=

So we need to buy 25 (24 will not be enough) increments of 1/4 cubic yards.
