Answer:

y=-4x-4

Step-by-step explanation:

m=-4

point(-2,4)

y-4 = -4 (x- (-2) )

y-4 = -4 (x+2)

y-4 = -4x -8

y = -4x -4

Step-by-step explanation:

we are going to use quadratic equation for this particular question . so now we are going to change the signs i.e from negative to positive or from positive to negative(-2 will turns to +2) nd +4 will turns to-4)

therefore, (x+2)(x-4) then we na expand the bracket x(x-4)+2(x-4)

x square -4x+2x-8

therefore the equation is nothing but x square-2x-8

Lamonte and Fwam own competing taxicab companies. Both cab companies charge a one-time pickup fee for every ride, as well as a c
maksim [4K]

The cab rate model for Fwam will be given as y=2.8x+4.

<h3>What is an equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Here we have an equation model for Lamonte y=2.2x+2.5 here y is the total cost and x is the distance in miles.

So here Fwam charges a $4 pick up fee and $2.80 per mile. The equation model will be:-

y=2.8x+4.

Hence cab rate model for Fwam will be given as y=2.8x+4.

Which of the following trigonometric ratios are correct?
den301095 [7]

Hi there! In this problem, you should have the knowledge of three basic Trigonometric Ratio.

  • sinA = opposite/hypotenuse
  • cosA = adjacent/hypotenuse
  • tanA = opposite/adjacent

Now that we know three basic ratio. Let's check each choices!

  • sin50° = d/c

This choice is wrong because we focus on the 50° angle. When we focus on 50°, sin50° should be d/x and not d/c.

  • sin50° = c/x

This choice is also wrong because in ratio, it's cos50° that adjacent/hypotenuse.

  • tan50° = d/c

This choice is correct! As ratio states, tanA = opposite/adjacent.

  • tan50° = x/c

This choice is wrong. x/c is a reciprocal of cosine which is 1/cos. We call the reciprocal of cosine as secant or sec in short.

  • cos50° = x/d

This choice is wrong as x/d is a reciprocal of sine which is 1/sin. We call the reciprocal of sine as cosecant or cosec/csc in short.

  • cos50° = c/x

This choice is right by the ratio. Nothing really much to explain since we follow by ratio that is defined.

Answer

  • tan50° = d/c
  • cos50° = c/x

Questions can be asked through comment.

Furthermore, tan also has its reciprocal form itself which is called cotangent also known as cot in short.

Hope this helps, and Happy Learning! :)

Hey can you please help me posted picture of question
puteri [66]
We have the following function:
 P (m) = m / 6 + 9
 Clearing m we have:
 m = 6 * (p-9)
 m= 6*p - 6*9
 Rewriting:
 m (p) = 6p-54
 Answer:
 
The inverse function for this case is given by:
 
m (p) = 6p-54
