When X=5 and y=10 in the formula A =xy-20. Find A

Delicious77 [7]

Answer:

A = 30

Step-by-step explanation:

x = 5

y = 10

A = xy - 20

substitute 5 and 10 in the place of x and y

(5*10) - 20

50 - 20

A = 30

Find the y-intercept and the axis of symmetry of f(x)=ax2+2ax+3.

Sonbull [250]

Answer:

$y= cx^2 +dx +e$

We see that:

$c = a, d= 2a , e= 3$

The axis of symmetry is defined by this formula:

$X= - \frac{d}{2c}$

And replacing we got:

$X= -\frac{2a}{2a}= -1$

Thn the axis of symmetry would be X=-1

Step-by-step explanation:

For this case we have the following function:

$y = ax^2 +2ax +3$

If we compare this function with the general expression of a quadratic formula given by:

$y= cx^2 +dx +e$

We see that:

$c = a, d= 2a , e= 3$

The axis of symmetry is defined by this formula:

$X= - \frac{d}{2c}$

And replacing we got:

$X= -\frac{2a}{2a}= -1$

Thn the axis of symmetry would be X=-1

Let f(x)=1/x and g(x)=x^3. Find f(x) -g(x)

kari74 [83]

To find f(x) - g(x), simply subtract g(x) from f(x).

$\frac{1}{x} -x^3$

If you need to simplify, we can find a common denominator:

$\frac{1-x^4}{x}$
