The midpoint is calculated by averaging the coordinates of its endpoints:
Now we can use the usual distance formula to get the length of SM:
Answer:
Minimum: (2,4)
Step-by-step explanation:
h(x)=3(-4x)+16
=3(-4x+4-4)+16 (- For the balance of equation, and attention 1)
=3-3*4+16
=3+4
<h3>Attention:</h3>
1.
2. The formula for the vertex form is y = , the vertex is (h,k)
Given:
Gary bikes 3.5 miles in of an hour.
To find:
The distance covered by Gary in of an hour at the same speed.
Solution:
We have,
Distance covered in of an hour = 3.5 miles
Distance covered in hour miles
Distance covered in of an hour miles
miles
miles
Therefore, Gary could travel 10.5 miles in of an hour.
8×25=200
and
200×23=4600
so 8×25×23=4600
Step-by-step explanation:
Ok. First of all, we need to follow the order of operations: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. We don't have any parentheses, exponents, or division to resolve, so you can skip those. So now you have: Multiplication, Addition, and Subtraction. We have multiplication in each term, but each term is fully simplified, so we have Addition and Subtraction left.
With that out of the way, let's go ahead and rearrange this equation so it is easier to solve. (<em>Note: we can only rearrange terms that are positive because subtraction is not commutative. But we can turn negative terms into "positive" terms by the method shown below.</em>)
4a - 7b + 2ab - a + b
4a + (-7b) + 2ab + (-a) + b (<em>Now the terms are all positive, so we can rearrange them, but they still have the same value.</em>)
4a + (-a) + 2ab + (-7b) + b
3a + 2ab + 7b
And there we go. Our answer is fully simplified. If you can understand this, you'll be able to simplify without isolating and rearranging the terms each time.
Hopefully this was helpful and not confusing.
