Alright! To solve this one you first have to find out what 1cm is equal to in km, to do that you have to divide 18km by 3cm:
[18 ÷ 3] = 6.
Now we know that 1cm is 6km. To find how far apart they are on the map you simply divide 54km by 6km:
[54 ÷ 6] = 9.
They are 9cm apart on the map.
Answers:
1: y = 1x + 0.5
3: the y-intercept shows that the original data began above 0 and has had a steady increase since. (not sure abt this one)
4: I'm sorry i don't know this one
5: the data collection shows that the height to arm span has a ratio of 1 throughout you can tell this by using the line of best fit.
6: according to the line of best fit the height of the person will also be about 66 inches.
7: according to the line of best fit the arm span will also be about 74 inches.
Step-by-step explanation:
12-(-6)=18
-18+12=-6
Right side:
(1/27)^(2x+10)
=(3^-3)^(2x+10)
= 3^(-6x - 30)
Re-write both sides:
3^(4x-5) = 3^(-6x - 30)
from here, you can solve x
4x - 5 = -6x - 30
4x + 6x = -30 + 5
10x = -25
x = -2.5
You solve this by using google.com or YouTube.com
Or just pay attention in class to get this.
