I just aswerd these
1. solve for x in first to just find nterms of y
x=12-y
sub that for x in other one
first divide that one by 2 to make it easier
2x-y=18
2(12-y)-y=18
24-2y-y=18
24-3y=18
minus 24 both sides
-3y=-6
divide -3
y=2
D is answer
2.
find intersection of x+y=5 and -2x+3y=6
or easiers, just test the intersections
wait, they all intersect in the same place
this is super easy
pick ANY point that is in that reigon and see if it is true
A, if we pick lets say (5,5)
that is false for x+y<5
not A
B
pick (10,0)
false for first one
not B
C
pick (0,0)
true for first
false for 2nd
not C
D. pick (-10,0)
true for first
true for 2nd
answer is D
8.
time times object=time taken
35 for wall
frame or door=21
the first equation has to be in terms of minutes
2nd has to be in terms of loads
first one is
35w+21d=595
2nd is
9w+13d=267
D is answer
9.
find intersection
at p=3 and w=12
D is answer
the answer is D for all the questions
Answer:
Poland
Step-by-step explanation:
Despite the Britain and France's efforts to appease Germany by giving Hitler the Sudetenland, Hitler did not hesitate the break the peace agreement he had signed with the Britain and France and proceed to invade Poland in his question to capture all of Europe, and, possibly, the entire world.

Answer:
37,139
Step-by-step explanation:
Given the following :
Population in 2002 = Initial population (P0) = 22,800
Growth rate (r) = 5% = 0.05
Growth in 2012 using the exponential growth function?
Time or period (t) = 2012 - 2002 = 10years
Exponential growth function:
P(t) = P0 * (1 + r) ^t
Where P(t) = population in t years
P(10) = 22800 * (1 + 0.05)^10
P(10) = 22800 * (1.05)^10
P(10) = 22800 * 1.62889
P(10) = 37138.797
P(10) = 37,139 ( to the nearest whole number)
