Answer:

Vertex of parabola (-1, -10)

Step-by-step explanation:

For a given quadratic y = ax² + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k. If you've already learned the Quadratic Formula, you may find it easy to memorize the formula for k, since it is related to both the formula for h and the discriminant in the Quadratic Formula: k = (4ac – b2) / 4a.

The simplified form of 10 - 3 x 2/1+1 is 5. This is obtained by applying the order of operations in mathematics, which first executes multiplication and division from left to right then does addition and subtraction from left to right.

To simplify the expression 10 - 3 x 2/1 + 1 using the Order of Operations (PEMDAS/BODMAS), we follow these steps:

1. Parentheses/Brackets (None): There are no parentheses in the expression.

2. Exponents/Orders (None): There are no exponents.

3. Multiplication and Division (Left to Right): Multiply 3 by 2, which equals 6.

4. Addition and Subtraction (Left to Right): Now, perform the remaining operations from left to right: 10 - 6 + 1.

Now, solve the expression step by step:

1. 10 - 6 = 4

2. 4 + 1 = 5

So, the final answer is 5.

The given expression, 10 - 3 x 2/1 + 1, is simplified using the Order of Operations (PEMDAS/BODMAS). First, we perform multiplication and division from left to right. We multiply 3 by 2, resulting in 6. Then, we move on to addition and subtraction. Subtracting 6 from 10 gives us 4. Finally, we add 1 to 4, resulting in the final answer, which is 5.

The Order of Operations is crucial in mathematics to ensure that expressions are evaluated consistently and correctly. It helps us avoid ambiguity and ensures that mathematical operations are carried out in the correct sequence. In this case, following the order of operations leads us to the correct simplified answer of 5.

Answer: the answer is 5

Step-by-step explanation:

first you would multiply 3 x 2 = 6. then you would divide 6 by 1 and get 6. You then take 10-6+1 and it equals 5.

B; 25.65+13.23+6.35=45.23

To do this mentally just add the 2 decimals places together first (1.23). Then just add the whole numbers (44). Then add the 2 numbers together, 44+1.23=45.23
