Please help if you could

Goshia [24]

Answer:

f(x)= 6x+9....

Step-by-step explanation:

The given equation is:

y-6x-9=0

Add 6x+9 at both sides:

y-6x-9+6x+9=0+6x+9

Solve the like terms:

on the L.H.S -6x will be cancelled out by +6x and -9 will be cancelled out by +9

y=6x+9

Now convert it in function notation:

f(x)=y

f(x)= 6x+9....

Solve the system and give your answer as a coordinate point in the form (k, c) k+c=100 51k+11c=2500

Aleks [24]

Answer:

k = 35, c = 65

Step-by-step explanation:

Solve the following system:

{c + k = 100 | (equation 1)

{11 c + 51 k = 2500 | (equation 2)

Swap equation 1 with equation 2:

{11 c + 51 k = 2500 | (equation 1)

{c + k = 100 | (equation 2)

Subtract 1/11 × (equation 1) from equation 2:

{11 c + 51 k = 2500 | (equation 1)

{0 c - (40 k)/11 = -1400/11 | (equation 2)

Multiply equation 2 by -11/40:

{11 c + 51 k = 2500 | (equation 1)

{0 c+k = 35 | (equation 2)

Subtract 51 × (equation 2) from equation 1:

{11 c+0 k = 715 | (equation 1)

{0 c+k = 35 | (equation 2)

Divide equation 1 by 11:

{c+0 k = 65 | (equation 1)

{0 c+k = 35 | (equation 2)

Collect results:

Answer: {c = 65 , k = 35

Quadratic Functions Put the equationy = x^2 + 14a + 40 into the form y = (x - h )^2 + k: Answer: y Preview Get help: Video Poins

Artist 52 [7]

Answer:

The required form is $y=(x+7)^2-9$ .

Step-by-step explanation:

Consider the provided quadratic function.

$y=x^2 + 14x + 40$

We need to put the equation into the form $y = (x - h )^2 + k$

Add and subtract 49 in order to make the above function a perfect square.

$y=x^2 + 14x+49-49 + 40$

$y=x^2 + 14x+7^2-49 + 40$

$y=(x+7)^2-49 + 40$

$y=(x+7)^2-9$

Hence, the required form is $y=(x+7)^2-9$ .
