Answer: 12
Step-by-step explanation:
I will assume those are coordinates.
The distance between 2 points is given by √ (x2 − x1)^2 + (y2 − y1)^2.
Replacing the values, we get √ (5 − 5)^2 + (6 − -6)^2 = √0+144 = 12
8.33333333. You know you can use a calculator.
Determine whether the point 1,5 is a solution to the system of inequalities below y>3x , y>/2x+1
ANSWER
C. 7
EXPLANATION
We want to evaluate
We use the order of operations PEDMAS.
Dealing with the parenthesis first,we have
Note that:
and
Our expression now becomes:
Next, we add to get:
We finally subtract to get,
The correct answer is C
The distributive property "distributes" a number through all numbers/terms in a set of parentheses by multiplication.
EXAMPLES
Equivalent expressions are the first and last steps. The middle step just shows the work.
5(2 + 3x)= (5*2) + (5*3x)= 7 + 15x
4(2x + 4y)= (4*2x) + (4*4y)= 8x + 16y
10(4x + 5)= (10*4x) + (10*5)= 40x + 50
ANSWER:
Only one pair below is needed for your answer.
5(2 + 3x)= 7 + 15x
4(2x + 4y)= 8x + 16y
10(4x + 5)= 40x + 50
Hope this helps! :)
