Mathematics

Answer: The missing coordinate R is 5.

Step-by-step explanation:

11=1/2(-4) + B

11=-2 +B  

B= 13

B represents the y-intercept

so we will use the equation y=mx + B  and we know the slope and y intercept.

r= 1/2(-16) + 13

r= 5

What is the value of the expression "two less than six times the difference of a number and five" when n = 9?
Burka [1]

Answer: The value of the expression when n=9 is 22

Step-by-step explanation:

In this case, you need to remember that:

1. Tthe word "less than" indicates a subtraction.

2.  By definition, the "Difference" in the result of a subtraction.

3. The word "times" indicates multiplication,

Based on the information given above, you know that  " Six times the difference of a number and five" can be expressed as:

6(n-5)

Then,  "Two less than six times the difference of a number and five" can be represented with this expression:

6(n-5)-2

Now you can substitute n=9 into the expression and the evaluate in order to find the value of the expression. This is:

6(9-5)-2=6(4)-2=24-2=22

Answer:

15 yds

Step-by-step explanation:

40 divided by 50 equals 4/5, so the lengths of the other triangle have to match that ratio. 3 fits into 12 four times and 15 five times, which makes it a four to five ratio.
