Answer:

y= -2x+9

Step-by-step explanation:

The equation will be written this way :

y= m*x+c

  • m is the slope
  • c is a constant
  • m =( f(4)-f(2))/(4-2)=(1-5)/2= -4/2 = -2
  • y = -2x+c
  • replace x and y by the coordinates of a point to get c
  • 1= -2*4+c
  • c = 9

y = -2x+9

Answer:

y=-9/4.5+9

Step-by-step explanation:

To find the equation you do y=mx+b which means y= slope + y-intercept.

To get the slop you do rise over run which in this situation is 9/4.5. And the y-intercept is when the line touches the y-axis and in this problem it is 9. So the answer is y=-9/4.5+9

joja [24]

Answer: The regular price of  the shirt is $20.

Step-by-step explanation:

To find the regular price, find a number that 25% of it is equal to 5.

Solve using the equation,

25% * x = 5     Where x is the regular price.

0.25x = 5  

    x= 20    

This means that the regular price is $20.

Which expression is equivalent to
Sunny_sXe [5.5K]

By taking a common factor, we will see that the equivalent expression is:

12*\sqrt[3]{6c}

<h3>How to find the equivalent expression?</h3>

Here we start with the expression:

5*\sqrt[3]{6c} + 7*\sqrt[3]{6c}

Notice that if we define:

\sqrt[3]{6c} = u

We can rewrite our expression as:

5u + 7u

Now we can take the common factor u to write:

(5 + 7)u = 12u

Now if we replace u y the cubic root, we will get:

12*\sqrt[3]{6c}

So the correct option is the third one.
