What is the value of the expression: 2 - (3x + 5y) if x = -3 and y = 4?
here is our equation,
[tex]2-(3x+5y)[/tex],
Now we will plug in our numbers
__________________
[tex]{\boxed{x=-3}}[/tex][tex]{\boxed{y=4}[/tex]__________________
[tex]2-(3\cdot-3+5\cdot4)[/tex]
simplify it and we get
[tex]2-(-9+20)[/tex]
[tex]2-11[/tex]
[tex]-9[/tex]
Hey there!
2 - (3x + 5y)
= 2 - (3(-3) + 5(4)
= 2 - (-9 + 20)
= 2 - 11
= -9
Therefore, your answer is: -9
Good luck on your assignment & enjoy your day!

Some events cannot be predicted with certainty, but we can determine how likely they are. The probability of an event is a measure of the likelihood that the event will take place.
Let’s take flipping a coin as an example. When the coin is flipped, there are two possible results, or outcomes—heads or tails. All possible outcomes of an event are called the event’s sample space, and the number of outcomes in the sample space is the sample size. In the event of flipping a coin, the sample space is {heads, tails} and the sample size is 2.
The probability of an event is represented as a fraction. The numerator of the fraction is the number of times an event occurs, and the denominator is the sample size.
Let’s find the probability of getting heads when a coin is flipped. A coin has two sides, and one of them is heads. So, the number of ways the event occurs is 1, and the number of possible outcomes is 2.
The probability of getting heads is (1/2), or 0.5. What do you think the probability of getting tails is? Why?
Now consider a different event, rolling a die. What is the probability of rolling a two on a die? What is the probability of rolling a multiple of two?
Answer:
the probability of getting tails is 1/2 the same reason as of heads
probability of 2 on a die: 1/6, multiple of 2: 1/2
Step-by-step explanation:
The numbers that can appear on a dice are:
{1,2,3,4,5,6}, so if we want 2 only there is only one in the outcomes so 1/6
now if we want multiples of 2 there are 3 of them in the outcomes {2,4,6}
so the probability 3/6 = 1/2
Answer:
Step-by-step explanation:
The two outcomes of the toss of a coin are heads or tails. For any individual toss of the coin, the outcome will be either heads or tails.

The quotient of 49 ÷ 3 or 49/3 is 16.33.
What is the difference between quotient and divisor?The number which divides a particular number is the divisor and the number which we get as a outcome is known as the quotient.
To determine the quotient of 49 ÷ 3.
49 ÷ 3 = 49/3 = 16.33 which is approximately is 17.
Therefore, the quotient of 49 ÷ 3 or 49/3 is 16.33 approximately is 17.

Square = 8.Step-by-step explanation:
Triangle is 2.
There are 4 triangles.
2 * 4 = 8.Then, we add 8 to the total:
8 + 8 = 16.On the other side, there are 2 squares.
8 * 2 = 16.We kept the counter weight thing balanced.
Every square is 8.
Explain how you would create opposite terms for the x-variable in this system.
3x – 6y = –8
-1x+4y=6
Answer:
Your answer would be, You can use the Elimination Method, by Multiplying, One or Both Equations by a Constant.
Solve System of Linear Equation:
3x - 6y = -8, -1/4x + 4y = 6 ====> y = 32 /21; x = 8 / 21
Steps:
[ 3x - 6y = -8, -1 / 4x + 4y = 6 ]
Isolate x for 3x - 6y = -8: x = -8 + 6y / 3
3x - 6y = -8
Add 6y both sides:
3x - 6y + 6y = -8 + 6y
Simplify:
3x = - 8 + 6y
Divide Both sides by 3:
3x / x = -8 / 3 + 6y / 3
Simplify:
x = -8 + 6y / 3
Substitute:
x = -8 + 6y / 3
[ 1 / 4 * -8 + 6y / 3 + 4y = 6 ]
Isolate:
-1 / 4 -8 + 6y / 3 + 4y = 6
y = 32 / 21
For x = -8 + 6y / 3
Substitute:
y = 32 / 21
x = -8 + 6 / 3 * 32 / 21
-8 + 6 / 3 * 32 / 21
x = 8 / 21
The Solution to the Systems of Equations are: y = 32 / 21; x = 8 / 21

Determine if the line below has a positive, negative, zero or undefined slope.
Positive Slope
Negative Slope
Zero Slope
Undefined Slope
PLEASE HELP!!!!!!!!!!!!!!!!!!!
Answer:
Positive slope.
Step-by-step explanation:
Look at the graph from left to right. As you do that, x is increasing. What's happening to y? It's getting larger--the points on the graph are getting higher and higher. That's positive slope: increasing x produces increasing y.
Negative slope occurs when x gets larger (move from left to right on a graph) and the values of y get smaller -- points on the graph get lower and lower. The graph falls from left to right.
Zero slope occurs when x gets larger and y stays the same. The graph is a horizontal line -- it does not rise or fall.
It costs $50 per hour to rent a jet ski. The total cost of a jet ski rental includes a flat fee plus an hourly fee. After 5 hours, the total cost is $265. Write an equation that represents the total cost y after x hours.
Answer:
50x + 15 = y
Step-by-step explanation:
You have to find the flat cost by multiplying the 50 by 5, and then plugging that in for your first constant, and then solve by subtracting that from 265 to get your flat rate, and then put it all together. (see attachment for details)
