The function f(x) = –x2 + 20x – 75 models the profit from one customer, in dollars, a shop makes for printing photos, where x is

trasher [3.6K]

The function is graphed as shown below

Part A:

We use the formula $- \frac{b}{2a}$ to find the vertex of the function. A quadratic function of the form of $a x^{2} +bx+c$ and equating this form to the given function $- x^{2} +20x-75$ , we have
$b=20$ and $a=-1$ .

Substituting $a$ and $b$ into the vertex formula, we have
$x=- \frac{20}{2(-1)}=10$ , as shown in the graph

This calculation means that the highest profit is achieved when the number of photo printed equals to ten photos

Part B:

We can find solution to this equation by factorising

$- x^{2} +20x-75=0$
$-( x^{2} -20x+75)=0$
$x^{2} -20x+75=0$
$(x-5)(x-15)=0$
$x=5$ and $x=15$ , as shown in the graph

The two values means that the company makes no profit when they either produce 5 or 15 photos

Answer:

A) (2x+15)=65=180°

Step-by-step explanation:

Hey there!

It's a straight line, which means that the sum will be 180°.

So, (2x+15)=65=180°

Hope this helps!

Find common denominators. 10 is the common denominator. Multiply 2 to numerator and denominator of -3/5

(-3/5)(2/2) = -6/10

x + 1/10 = -6/10

Isolate the x. Subtract 1/10 from both sides

x + 1/10 (-1/10) = -6/10 (-1/10)

x = -6/10 - 1/10

x = -7/10

-7/10 is your answer for x

hope this helps
