Answer:
The approximate length of segment EF is 7 unit
Step-by-step explanation:
Given figure is the graph having E and F coordinate
The coordinate of point E = (
,
) = ( - 2 , -4 )
The coordinate of point F = (
,
) = ( 2 , 2 )
Let The distance between the points E and F = D
So, D = 
or, D = 
Or, D = 
or, D = 
∴ D = 
I.e D = 7.21 unit
So, Approximate value of D = 7 unit
Hence The approximate length of segment EF is 7 unit . Answer
Here is the set up:
x
x + 2
x + 4
x^2 + (x + 2) + (x + 4)^2 = 170
Take it from here.
Answer:I think it’s D
Step-by-step explanation:
x = # of hours the bike was rented.
$40 = $12 + $7x
Subtract $12 from both sides.
$28 = $7x
Divide both sides by $7
4 = x
Sandy rented the bike for 4 hours.
Answer:
-4x + y + 6z
Step-by-step explanation:
2x + 5y - z + (-6x - 4y + 7z) < distribute positive 1 to (-6x - 4y + 7z)
2x + 5y - z - 6x - 4y + 7z < combine like terms to get the answer
2x - 6x = -4x
5y - 4y = y
-z + 7z = 6z
our new expression is:
-4x + y + 6z we cannot simplify this any further, so this is our answer
