The Correct choice is D
For the function f(x) = -x+8, f(x-k) = f(x)+k. Option (D) is correct.
What is function?Function is a combination of different types of variable and constants.
A function is denoted by f(x).
The given function is,
f(x) = -x+8,
Substitute x= x+k in the given function,
f(x+k) = -(x+k)+8
f(x+k) = -x-k+8
f(x+k) = -x+8-k
Substitute -x+8= f(x) here,
f(x+k) = f(x)-k
Substitute x= x-k in the given function,
f(x-k) = -(x-k)+8
f(x-k) = -x+k+8
f(x-k) = -x+8+k
Substitute -x+8= f(x) here,
f(x-k) = f(x)+k
Hence, option (D) is correct.

Answer:
Step-by-step explanation:
1) Determining the nature of roots:
Quadratic equation: ax² + bx +c = 0
Find D (Discriminant) using the D = b² - 4ac
If D = 0 , then the two roots are equal.
If D > 0, then the equation has two distinct real roots.
If D < 0, then the roots are complex/ imaginary.
One can find the sum and product of the roots using the below mentioned formula.
1) sum of roots = [tex]\frac{-b}{a}[/tex]
2) Product of roots = [tex]\frac{c}{a}[/tex]
If sum and product of the roots are given, one can frame the quadratic equation by x² - (sum of roots)*x + product of roots = 0
2) i) x² - 6x + 9 = 0
a = 1 ; b = -6 and c = 9
D = (-6)² - 4 * 1 * 9 = 36 - 36 = 0
D = 0. So, two equal roots
ii) x² - 4x + 3 = 0
a = 1 ; b = -4 ; c = 3
D = (-4)² - 4 * 1 * 3 = 16 - 12 = 4
D > 0. So, two distinct real roots.
iii) x² - 4x - 3 = 0
a = 1 ; b = -4 ; c = -3
D = (-4)² - 4*1*(-3) = 16 + 12 = 28 > 0
D > 0. So, two distinct real roots.
iv) x² - 4x + 7 = 0
a = 1 ; b = -4 ; c = 7
D =(-4)² - 4 *1 *7 = 16 - 28 = - 12
D< 0. So, two imaginary/ complex roots.
What is the equation of the line shown on the graph?
A y=x
B y=4x
C Y= -x
D Y =1/4 X
Answers
Take two points from the graph and solve for the slope:
Let (x1, y1) = (2, 8)
(x2, y2) = (4, 16)
substitute these values into the slope formula:
m = (y2 - y1)/(x2 - x1)
m = (16 - 8) / (4 - 2)
m = 8/2
m = 4
Therefore, the slope is 4.
The y-intercept is the y-coordinate of the point (0, b) where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.
Looking at the graph, the line crosses at the point of origin, (0, 0). Therefore, the y-intercept, b = 0.
The correct answer is option B) y = 4x.

Step-by-step explanation:
Mental math means to find a way to do this problem in your head without using paper, pencil or a calculator.
The question says there are 23 classes and each class is to collect 101 items.
The equation would be 23 x 101.
To do this in your head real quick, make the numbers easier to multiply.
Make the 101 items 100. That means you are telling each class to collect 1 less item or 23 less items total.
You can do this in your head real quick. 23 classes collecting 100 items is 2300 items.
You had each class collect 100 items instead of 101. That mean you didn't collect 23 items. So if you add those back in, you will get
2323 items.
Your turn: Type in two addition expressions, both of which have an output value of -100.
1) Use two negative numbers.
2) Use one positive number and one negative number.
