Answer:
The correct answer is C. All integers where n ≥ 1
The domain for n in the given arithmetic sequence is the set of positive integers.
The domain of the arithmetic sequence an = −4 + 4(n − 1) is the set of all possible values for n. In this case, since n represents the position in the sequence, it can only take on positive integer values starting from 1. Therefore, the domain for n is the set of all positive integers: {1, 2, 3, 4, ...}.

Answer:
27x+24
Step-by-step explanation:
distribute the 8 and add like terms (24x and 3x)
Answer:
5x - 30
Step-by-step explanation:
5 must multiply with what's in the bracket for being next to it
5 x X = 5x
5 x -8= -40
5x - 40 + 10
- 40 + 10 = -30
5x - 30
Answer:
-30+5x
Step-by-step explanation:
5(x-8)+10
x-8 evaluates to x-8
Multiply 5 by x-8
we multiply 5 by each term in x-8 term by term.
This is the distributive property of multiplication.
Multiply 5 and x
Multiply 1 and x
The x just gets copied along.
x
5 × x = 5x
Multiply 5 and -8
1
5 × -8 = -40
5*(x-8) evaluates to 5x-40
-40 + 10 = -30
The answer is -30+5x
5*(x-8)+10 evaluates to -30+5x
Answer: A proportional relation between two numbers, x and y is when:
y= k*x, where k is a real number.
this is read as "the number y is k times the number x" so y is proportional to x, and the constant of proportionality is k.
The equation in the problem is: y = 4x - 5, here you have an x-intercept equal to -5, this quantity breaks the proportionality relation. So in this case y is not proportional to x.
f(x)=2x−1
f(x)=−12x−1
f(x)=−2x−1
The straightline through the points (0, -1) and (-1, 1), represents the equation f(x) = -2x - 1. The correct option is D.
The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
For the equation f(x) = -2x - 1, we can see that the slope (m) is -2, and the y-intercept (b) is -1.
To graph this line, we can plot the y-intercept first, which is the point (0, -1) on the y-axis. Then, using the slope of -2, we can find another point on the line by moving 2 units up and 1 unit to the left, which gives us the point (-1, 1). We can continue this process to plot more points on the line, but two points are enough to draw a straightline.
So, we can draw a straight line through the points (0, -1) and (-1, 1), which represent the equation f(x) = -2x - 1.
