If x=9 and y=- -2 evaluate the following expression: x+y

Mathematics
1 answer:
mel-nik [20]3 years ago
4 0

Answer:

x + y = 11

Step-by-step explanation:

You would need to substitute the numbers into the expression.

Evaluate means that we need to work out what the answer would be.

x + y is equivalent to 9 - - 2.

- - is equivalent to +.

Therefore you would do 9 + 2, which equals 11.

Hope this helps :)

The order of mathematical operation is MDAS.
M - multiplication
D - division
A - addition
S - subtraction

3 - 3 x 6 + 2

Multiplication : 3 x 6 = 18
Division: none
Addition : + 3 + 2 = 5 (combine positive numbers)
Subtraction : 5 - 18 = -13

3 - 18 + 2 = -13

Pete sold 150 shares of stock a at $10.98 per share through his broker. His broker charges $28 per trade. How much money did Pet
Andrews [41]

Answer:

$1619

Step-by-step explanation:

From the first statement, he sold 150 shares at $10.98 per trade, this means the total amount in which the sale cost is 10.98 × 150 =

$1647

Now we are told that the broker charged an amount of $28 per trade. Hence , the amount left after the broker had removed his charges is the total amount minus the broker fee.

That equals, 1647 - 28 which is $1619

Determine whether the following statement is true or false.
fenix001 [56]

Answer:

Step-by-step explanation:

No it doesn't. When you get stuck on a question like this one, you should go to Desmos and graph the equation. I've done that for you.

Correctly stated the equation should read f(x) = (x + 2)^2 + 4

As you can see from the graph the vertex is at -2,4. To find the x value of the vertex, create a small equation

x + 2 = 0

x = - 2

That will turn what is inside the brackets into 0. The value for x is always what will turn (x + a) to zero.

How does a computer drawing program compare to using a compass and straightedge?
notsponge [240]
A computer drawing program generally has more steps compared to using a compass and straightedge, although not by much. In a computer drawing program, you can erase an error within a click of a button, compared to having to manually perfect and erase your work when using a compass and straightedge. Also, you immediately have access to an online drawing program as long as you have Internet connection and a computer compared to having to go out and buy a new compass and straightedge. Other than that, they're generally the same despite being different mediums.

Hope this helps!
