Answer:

m=-5

Step-by-step explanation:

distribute -3: -3m+6=21

subtract 6 from both sides: -3m=15

divide by negative three: m=-5

If 12a - 5 = 4a + 11 ,then a= what?
FinnZ [79.3K]

Answer:

a=2

Step-by-step explanation:

12a - 5 = 4a + 11

Subtract 4a from each side

12a-4a - 5 = 4a-4a + 11

8a -5 = 11

Add 5 to each side

8a -5+5 = 11+5

8a = 16

8a/8 = 16/8

a =2

Write an equation to model this proportional relationship, where x represents the length of the rectangle and y represents the w
Kay [80]

When Area of rectangle is constant, then the length x is inversely proportional to the width y of the rectangle.

x\propto  \frac{1}{y}

We know that the area of a rectangle is given by the product of the length and width of the rectangle.

Area = Length*Width

In this given problem,

The length of the rerectanglctangle is represented by x

and the width of the rectangle is represented by y

If the area of the rectangle is represented by A now.

So by the formula,

A = x*y

When A is constant then,

x = A/y

\therefore x \propto \frac{1}{y}

So from the above calculation we can conclude that about relation between length and width that,

"When Area of rectangle is constant, then the length x is inversely proportional to the width y of the rectangle."

What is the equation for the line with a slope of - 2/3 that passes through (0, -2)
viktelen [127]

Answer:

y= -2/3x-2

Step-by-step explanation:

Since we have a point and a slope, we can use the point slope formula

y-y_{1} =m(x-x_{1})

m is the slope. In this case, m is -2/3

y1 is the y coordinate of the point. In this case, it is -2

x1 is the x coordinate. In this case it is 0.

We can substitute these values into the formula

y- -2= -2/3(x-0)

Distribute -2/3

y+2 = -2/3*x + -2/3*0

y+2= -2/3x+0

Subtract 2 from both sides. We want to get y by itself. This is because we want our line to be in y=mx+b form.

y+2-2= -2/3x+0-2

y= -2/3x -2
