The -3 at the end of the equation would be the location of the lower point on the Y axis
and since the x-4 part is in between the vertical lines, that means the absolute value, which is always positive so the graph would make a V shape
so the correct graph would be D
The answer my dear friend is 260
Answer:
z = 5
x = 0
x = 1
Step-by-step explanation:
(z - 5)x^2 - (z - 5)x = 0 Take out z - 5 as a common factor
(z - 5)(x^2 - x) Take out x as a common factor
(z - 5)(x)(x - 1) Any one of these could equal 0. There are 3 solutons.
z - 5 = 0 Add 5 to both sides
z - 5 + 5 = 0 + 5
z = 5
===============
x = 0
===============
x - 1 = 0
x - 1 + 1 = 0 + 1
x = 1
==============
It looks like you have number 1 correct.
For number 2, what is alike is the exponent of 2. To combine them, add them together. You can do this because they are like terms (aka have the same variable and exponent)
3-4-1= -2. The answer is -2x^2
For number 3, those are not like terms. They either do not have the same variable (x or y) or they do not have the same exponent (1 or 2)
Both the exponent and the variable have to be the same for it to be a like term.
