B) for the total of both games it will be -1 points
C) the player had a better score on the first game because the added total on the first game was 2 while in the second game the total was -3
Step-by-step explanation:
40a. 2 for game 1. Add 3+(-1)= 3-1=2. -3 for game 2. Add -5 and 2 which gets -3

The choose C. 9/8
I hope I helped you^_^
Answer:
A. 49/81
B. -66/5
C. 9/8
Step-by-step explanation:
Slide 1:
Dividing fractions is exactly the same as multiplying fractions, you just flip the second fraction so the expression becomes -7/9*7/-9 which is 49/81.
[tex]\frac{-7}{9}*\frac{7}{-9} =\frac{-49}{-81} =\frac{49}{81}[/tex]
Slide 2:
To make 22 a fraction you just put it over 1 to make 22/1 and you just multiply across. -66/5
Slide 3:
To transform a mixed number into an improper fraction, you multiply the denominator by the whole number and then add the numerator. You take that number and put it over the denominator. You should now have -9/2. Multiply across. Cancel out the negatives. 9/8

Adoes thi involve coding?
Step-by-step explanation:
The graph will show the height of the red car as the time increases. Predict what this graph will look like before pressing start to run the ferris wheel.
How long does it take for the person riding the ferris wheel to make a complete revolution?
One revolution is ____
0 seconds
30 seconds
60 seconds
or
80 seconds
Answers
As per the graph, the time it takes for the person riding the ferris wheel to make a complete revolution is typically 60 seconds.
When the ferris wheel starts, the height of the red car will initially increase as it ascends from the ground level. As the ferris wheel continues to turn, the red car will reach its maximum height, usually at the topmost position of the ferris wheel, and then descend back to the ground level. This motion will repeat as the ferris wheel continues to rotate.
Now, let's determine how long it takes for the person riding the ferris wheel to make a complete revolution. One revolution corresponds to the time it takes for the ferris wheel to complete one full cycle of motion, going from its initial position, through its highest point, and back to its initial position. This time can be calculated by finding the time period of the sinusoidal function representing the height of the red car.
To find the time period, we need to know the duration for one complete cycle of the sine wave, which is the time it takes for the ferris wheel to complete one revolution. The time period can be derived from the angular speed of the ferris wheel. If we know the angular speed (usually given in rotations per minute or radians per second), we can calculate the time it takes for one revolution.

which is
4x -28 - 2x + 2 = -10
The equation 4(x − 7) −2(x+1) = −10 is equivalent to 4x -28 - 2x + 2 = -10
The correct answer would be an option (C)
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
Given that the equation as
⇒ 4(x − 7) −2(x+1) = −10
We have to open the brackets above and apply the distributive property of multiplication,
⇒ 4x -28 - 2x + 2 = -10
Thus, the equation 4(x − 7) −2(x+1) = −10 is equivalent to 4x -28 - 2x + 2 = -10
So the correct answer would be option (C)

A). –4, –2 and 0 only
B). 2, 4 and 6 only
C). 0, 2 and 4 only
D). –6, –4, –2 and 0 only
Answers
The correct option is B, 2, 4 and 6 only.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
The given inequality can be simplified as shown below,
3 + (1/2)x ≥ 4
(1/2)x ≥ 4 - 3
(1/2)x ≥ 1
x ≥ (1 × 2)
x ≥ 2
Since the value of x should be greater than or equal to 2. Therefore, it can be concluded that the values of x from the options that can satisfy this inequality are 2, 4 and 6 only.

Answers
Answer: These lines are perpendicular
Step-by-step explanation:
Let's use slope intercept form, y=mx+b (m=slope, b=y intercept)
Parallel lines have the same slope, or m
y=3x+7 and y=3x+32 are parallel because they have the same mPerpendicular lines have an opposite reciprocal slope
y=2x+13 and y= -1/2+2 are perpendicular because they are reciprocalsy=-2x+1 is already in slope intercept form. Let's change the other problem
