Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 
x ← is in slope- intercept form
with slope m = -
Answer:
15.71
Step-by-step explanation:
Length AB = sqrt ( (3-3)^2 + (2- - 1)^2) = sqrt9 = 3
Length BC = sqrt ( (-3-3)^2 + ( -1-2)^2) = sqrt 45
Lemgth CA = sqrt( 6^2) + (-1 - -1)^2 = sqrt 36 = 6
Perimeter = 3 + 6 + sqrt45
= 15.71
Answer:
x = -13
Step-by-step explanation:
-5(x - 1) = -7(x + 3)
Distribute on both sides.
-5x + 5 = -7x - 21
Add 7x to both sides.
2x + 5 = -21
Subtract 5 from both sides.
2x = -26
Divide both sides by 2.
x = -13
Answer:
0
Step-by-step explanation:
(x – y) – (x – y)
Distribute the minus sing
x-y-x+y
Combine like terms
x-x-y+y
0
Answer:
B. could become equal to the population mean if proper sampling techniques are employed.
Step-by-step explanation:
If any similarities it does not mean equal.
