Using the completing-the-square method, rewrite f(x) = x2 + 10x + 7 in vertex form

mr Goodwill [35]

Answer:

f(x) = (x - (-5))^2 + (-18)

Step-by-step explanation:

Given:

f(x) = x^2 + 10x + 7

Rewrite f(x) in vertex form

Solution:

f(x) = ax^2 + bx + c is a quadratic function.

The vertex form of f(x) is a(x - h)^2 + k, where (h, k) is the vertex.

=> f(x) = x^2 + 10x + 7

= x^2 + 10x + 25 - 18

= (x + 5)^ - 18

= (x - (-5))^2 + (-18)

=> f(x) can be rewritten in form of a(x - h)^2 + k, where (h, k) is the vertex, with a = 1, h = -5, k = -18

Given that the points ( 16 , − 5 ) and ( − 40 , 16 ) lie on a line, what is the equation of the line? Select two answer.

djyliett [7]

Answer:

The equation of line with given points is Y = - $\frac{3}{8}$ X + 1

Step-by-step explanation:

Given as :

The points are ( 16 , - 5 ) And ( -40 , 16 )

The line equation in points form :

Y - y1 = m ( X - x1)

Where m is the slope of line

Now , m = $\frac{y2 - y1}{x2 - x1}$

Or, m = $\frac{16 +5}{-40 - 16}$

Or, m = $\frac{21}{- 56}$

SO, Y + 5 = m ( X - 16)

Put the value of slope

∴ Y + 5 = $\frac{21}{-56}$ ( X - 16)

Or, ( - 56) × ( Y + 5 ) = 21 X - ( 21 × 16 )

Or, - 56 Y - 280 = 21 X - 336

Or, - 280 + 336 = 21 X + 56 Y

Or, 56 = 21 X + 56 Y

∴ Y = - $\frac{21}{56}$ X + 1

Or, Y = - $\frac{3}{8}$ X + 1

Hence The equation of line with given points is Y = - $\frac{3}{8}$ X + 1 Answer
