Answer:
Step-by-step explanation:
The equation to find the slope given 2 points is (y2-y1)/(x2-x1). Lets say that (-5,-2) is x1 and y1 respectively, and (-3,-6) is x2 and y2 respectively. Now, you'd substitute these values into the equation to get [(-6)-(-2)]/[(-3)-(-5)]. When you simplify this, you get (-4/2). When you simplify this further, you get -2. Your slope is -2.
Answer:
the answer is 16
Step-by-step explanation:
If you wish to<u> mentally estimate</u> the <u>total cost</u> of items, <u>rounding </u>off the items to the<u> nearest half dollar</u>, then you have to consider all five items separately.
Five items cost $1.85, $.98, $3.49, $9.78, and $6.18.
1. $1.85≈$2;
2. $0.98≈$1;
3. $3.49≈$3.50;
4. $9.78≈$10;
5. $6.18≈$6.
Then the total cost is
$2 + $1 + $3.50 + $10 + $6 =$22.50.
Answer: correct choice is C
Given:
The equation is:
To find:
The next step in simplifying the equation by using distributive property.
Solution:
Distributive property: According to this property if a, b and c are three real numbers, then
We have,
Using the distributive property, we get
It can be written as:
Therefore, the next step of the simplification is .
