Answers
Answer:
option A is correct
Step-by-step explanation:
mod's has a simple function -
if |x| is given it simply means that the value of "X" can't be negative
Option A is correct, |–3| = 3 and –|–4| = –4 is true statement.
What is Number system?A number system is defined as a system of writing to express numbers.
The absolute value or modulus of a real number x, denoted |x|, is the non-negative value of x without regard to its sign.
|-x|=x
For option A
|–3| = 3 and –|–4| = –4 is true
For option B
|–3| = 3 and –|4| = 4 is not true because –|4| is -4.
For option C
–|3| = 3 and |4| = 4 is not true because –|3| is -3
For option D
|–3| = 3 and |–4| = –4 is not true because |-4| is 4
Hence, option A is correct, |–3| = 3 and –|–4| = –4 is true statement.

Graph the line with slope 8 and y-intercept −8.
Answers
To create the slope 8, you would have to do the rise over run:8/1. which means u go up 8 units and to the side one unit and you keep doing that. And since the y-intercept is -8, then you start your first point at -8 and continue to go up.

What is graph?Graphing basic functions like linear functions and quadratic functions is easy. The basic idea of graphing functions is
Identifying the shape if possible. For example, if it is a linear function of the form f(x) = ax + b, then its graph would be a line; if it is a quadratic function of the form f(x) = ax2 + bx + c, then its a parabola.
finding some points on it, by substituting some random values of x and finding the corresponding values of y by substituting each value into the function.
For graphing quadratic function also, we can find some random points on it. But this may not give a perfect U-shaped curve. This is because, to get a perfect U-shaped curve, we need where the curve is turning. i.e., we have to find its vertex. After finding the vertex, we can find two or three random points on each side of the vertex and they would help in graphing the function.
Given:
slope= 8
y- intercept = -8
So, the equation can be
y= mx+ c
y= 8x - 8

Find all excluded values for the expression. That is, find all values of x for which the expression is undefined.
x+6/x² - 6x-27
Answers
Answer:
The values of x for the expression is undefined is -3 or 9
Step-by-step explanation:
Given function,
[tex]f(x) = \frac{X +\ 6}{X^2 - 6X-27}[/tex]
The values of x for which the expression is undefined is obtained when the denominator is equal to zero, from the expression it is given by;
x² - 6x - 27 = 0
Factorize the equation
x² + 3x - 9x - 27 = 0
x (x + 3) -9(x + 3) = 0
(x + 3)(x - 9) = 0
x = -3 or x = 9
Therefore, the values of x for the expression is undefined is -3 or 9

A square window has an area of 1,232 in2. (a) What is the length of 1 side of the window? Round your answer to the nearest tenth. Show all of your work. (1 point for the correct answer and 1 point for showing how you got your answer)
Answers
x = length of one side.
1,232in^2 = x^2
Take the sqrt of both sides.
35.1 in = x
The length of one side = 35.1 in
Step-by-step explanation:
We know that,
area of square = a²
→ 1,232 = a²
→ a = √1232
→ a = 35.0 in
Nearest 10th = 35.1 in

Drag the tiles to the correct boxes to complete the pairs. Match the angle measurements in radians with equivalent measurements less than or equal to 360°.
Answers
Answer:
60° =19π/3
288°=22π/9
315°=23π/4
80°=18π/5
Step-by-step explanation:
The question is incomplete. Find the completed question in the attachment.
We are to convert the radian values to the corresponding degrees that are less than 360°
Since π rad = 180°
For 23π/4:
If π rad = 180°
23π/4 = x
Cross multiply:
πx = 23π/4 × 180
x = 23π/4π × 180
x = (23×180)/4
x = 1035°
Next is to scale down 1035° to a degree less than 360 and to do this we will be subtracting multiples of 360° from the value gotten.
x = 1035 - (360×2)
x = 1035 - 720
x = 315°
Hence 23π/4 = 315°
For 18π/5:
If π rad = 180°
18π/5 = y
Cross multiply:
πy = 18π/5 × 180
y = 18π/5π × 180
y = (18×180)/5
y = 648°
In scaling down:
y = 648°-360°
y = 288°
Hence 18π/5 = 288°
For 22π/9:
If π rad = 180°
22π/9 = t
Cross multiply:
πt = 22π/9 × 180
t = 22π/9π × 180
t = (22×180)/9
t = 440°
In scaling down:
t = 440-360°
t = 80°
Hence 22π/9 = 80°
For 19π/3:
If π rad = 180°
19π/3 = y
Cross multiply:
πy = 19π/3 × 180
y = 19π/3π × 180
y = (19×180)/3
y = 3420/3
y = 1140°
In scaling down:
y = 1140°-(3×360)°
y = 1140-1080
y = 60°
Hence 19π/3 = 60°
Answer:
the other person was almost right except they mixed up 2 of them. this is the right answer, i hope this helps :)
60° =19π/3
288°=18π/5
315°=23π/4
80°=22π/9

if (x,y) is the solution to the system of equations above, what is the value of 3x - y?
Answers
3x - y = 5
Step-by-step explanation:2x + y = 10 | ×2
x - 2y = -5
4x + 2y = 20
x - 2y = -5
add
4x + x + 2y - 2y = 20 - 5
5x = 15
x = 15 : 5
x = 3
replace x
4(3) + 2y = 20
12 + 2y = 20
2y = 8
y = 8 : 2
y = 4
3x - y =
= 3(3) - 4
= 9 - 4
= 5
