Answer:

f\left(0\right)=\left(0\right)^2-4\left(0\right)=0-0=0

f\left(1\right)=\left(1\right)^2-4\left(1\right)=1-4=-3

f\left(2\right)=\left(2\right)^2-4\left(2\right)=4-8=-4

f\left(3\right)=\left(3\right)^2-4\left(3\right)=9-12=-3

f\left(4\right)=\left(4\right)^2-4\left(4\right)=16-16=0

Step-by-step explanation:

Given the function

f\left(x\right)=x^2-4x

Putting x=0 in the equation to find f(0)

f\left(x\right)=x^2-4x

f\left(0\right)=\left(0\right)^2-4\left(0\right)=0-0=0

   

Putting x=1 in the equation to find f(1)

f\left(x\right)=x^2-4x

f\left(1\right)=\left(1\right)^2-4\left(1\right)=1-4=-3

Putting x=2 in the equation to find f(2)

f\left(x\right)=x^2-4x

f\left(2\right)=\left(2\right)^2-4\left(2\right)=4-8=-4

Putting x=3 in the equation to find f(3)

f\left(x\right)=x^2-4x

f\left(3\right)=\left(3\right)^2-4\left(3\right)=9-12=-3

Putting x=4 in the equation to find f(4)

f\left(x\right)=x^2-4x

f\left(4\right)=\left(4\right)^2-4\left(4\right)=16-16=0

3x + y = 10<br> x = 2y + 1 <br><br> simplifying
Vinvika [58]

Answer:

y = 1 , x = 3

Step-by-step explanation:

3x + y = 10

x = 2y + 1

3(2y + 1) + y = 10

6y + 3 + y = 10

7y = 7

y = 1

x = 2(1) + 1

x = 3

What is the answer??
Amanda [17]

Answer:

angle 1= 104                angle 2= 76

Step-by-step explanation:

angle 1 equals x+66 and angle 2 equals 2x so you set up an equation where they are the sum of 180 degrees because the angles are supplementry angles.

x+66+2x=180                        set the sum of the angles to 180

3x+66=180                            combind like terms

3x=144                                   subract 66 from both sides

x=38                                      divide 3 from both sides

Now you put x back into the measurments

angle 1= (x+66)                              angle 2= 2x

              (38+66)                                           2×38

angle 1= 104                                   angle 2= 76

Or after you know angle 1 you can subtract angle 1 from 180 to get angle 2.

.75x-20= 620 what does x equal rounded to the nearest 100?
vodomira [7]

To solve this, we’ll have to use inverse operations.

Since addition is the inverse to subtraction, we’ll add 20 to 620.

20 + 620 = 640

From there, since division is the inverse of multiplication, we’ll divide .75 by 640.

640/.75 = 853.33333 repeating. We can round this to 853.33, to round to the nearest hundredth.

Therefore, 853.33 would be your answer! You can check this by solving the equation forwards (853.33 x .75 = ~640, 640 - 20 = 620.)

Hope this helps! :)
