-4 5/1 as a simplified fraction?

Andrej [43]

We have that
(c-4)/(c-2)=(c-2)/(c+2) - 1/(2-c)
- 1/(2-c)=-1/-(c-2)=1/(c-2)

(c-4)/(c-2)=(c-2)/(c+2)+ 1/(c-2)------- > (c-4)/(c-2)-1/(c-2)=(c-2)/(c+2)
(c-4-1)/(c-2)=(c-2)/(c+2)---------------- > (c-5)/(c-2)=(c-2)/(c+2)

(c-5)/(c-2)=(c-2)/(c+2)------------- > remember (before simplifying) for the solution that c can not be 2 or -2
(c-5)*(c+2)=(c-2)*(c-2)------------------ > c²+2c-5c-10=c²-4c+4
-3c-10=-4c+4----------------------------- > -3c+4c=4+10----------- > c=14

the solution is c=14

the domain of the function is (-∞,-2) U (-2,2) U (2,∞) or
all real numbers except c=-2 and c=2

Given the point (2,3) and the slope of 4 ,find y when x=22

Mariulka [41]

Y - y₁ = m(x - x₁)
y - 3 = 4(22 - 2)
y - 3 = 4(20)
y - 3 = 80
+ 3 + 3
y = 83

What is the first step when rewriting y = 3x2 9x – 18 in the form y = a(x – h)2 k?

stiks02 [169]

A quadratic equation has the general form of: 

y=ax² + bx + c

It can be converted to the vertex form in order to determine the vertex of the parabola. It has the standard form of:

y = a(x+h)² - k

This can be done by completing a square. The steps are as follows:

y = 3x2 + 9x – 18
y = 3(x2 + 3x) – 18
y + 27/4= 3(x2 + 3x+ 9/4) – 18
y = 3(x2 + 3/2)^2 – 99/4

Therefore, the first step is to group terms with the variable x and factoring out the coefficient of x^2.
