Help with these please! Write the equation in slope intercept form (y=mx+b) of each graph.
olga_2 [115]
Y=-1/2+2

The y intercept is clearly 2 and you're going down 2 over two every time so your slope is -1/2.

For any quadratic functions, ax² + bx + c, we can easily find the x-coordinate of its vertex through the use of the formula below.

x_{vertex} = \frac{-b}{2a}

where a and b are the coefficients of the function. For f(x), we have a = -1 and b = -16. Thus, we have
 
x_{vertex} = \frac{-16}{2(-1)}
x_{vertex} = 8

Since we now have the x-coordinate of the vertex, we can just easily substitute 8 into f(x) as shown below.

y_{vertex} = f(8) = -(8)+16(8)-60
y_{vertex} = 60

Thus, the vertex of f(x) is (8, 60). The vertex of the function shows the maximum value that the function can reach. For this particular case, the vertex represents the maximum profit that the shop owner could earn.

The x-intercepts of the function are the values of x when f(x) is zero. By equation f(x) with zero, we can solve the quadratic equation to find the x-intercepts as shown below.

-x^{2}+16x-60 = 0
x^{2}-16x+60=
(x-6)(x-10) = 0
x = 6
x=10

From this, we can see that the x-intercepts are (6, 0) and (10, 0). We just discussed that the x-intercepts are the values of x when y is zero. So, for this case it means that the shop does not earn a profit if they sell 6 or 10 candles. Basically, the x-intercepts represent the number candles sold if the shop wants to break even.

Solvex²= 12x-15 by completing the square. Which is the solution set of the equation?
natka813 [3]

The solution to the equation by completing the square is (6 - √21, 6 + √21)

<h3>How to complete the square?</h3>

The equation is given as:

x²= 12x-15

Rewrite as:

x² -12x = -15

Take the coefficient of x

k = -12

Divide by 2

k/2 = -6

Square both sides

k/4 = 36

Add 36 to both sides of x² -12x = -15

x² -12x + 36 = -15 + 36

Evaluate the sum

x² -12x + 36 = 21

Express the equation as a perfect square

(x - 6)² = 21

Take the square root of both sides

x - 6 = ±√21

Add 6 to both sides

x = 6 ± √21

Split

x = (6 - √21, 6 + √21)

Hence, the solution to the equation by completing the square is (6 - √21, 6 + √21)
