3 is the scale factor you would use to dilate Figure A to Figure B.
Congruent means like the same thing so i would say the 2 right one which might be (B and D i guess) hope it helps and have a great day
Cool you're in K12 so am I. <span />
Answer:
(X+2)(v-5)
Step-by-step explanation:
first, group and factor out the greatest common factor and combine to get (x+2)(v-5)
Answer:
80° , 100°, 80°
Step-by-step explanation:
∠ 1 and ∠ 2 form a straight line and sum to 180° , then
2x + 40 + 2y + 40 = 180
2x + 2y + 80 = 180 ( subtract 80 from both sides )
2x + 2y = 100 → (1)
∠ 1 and ∠ 3 are vertical angles and are congruent , then
2x + 40 = x + 2y ( subtract x from both sides )
x + 40 = 2y ( subtract 40 from both sides )
x = 2y - 40 → (2)
Substitute x = 2y - 40 into (1)
2(2y - 40) + 2y = 100
4y - 80 + 2y = 100
6y - 80 = 100 ( add 80 to both sides )
6y = 180 ( divide both sides by 6 )
y = 30
Substitute y = 30 into (2)
x = 2(30) - 40 = 60 - 40 = 20
Thus x = 20 and y = 30
Then
∠ 1 = 2x + 40 = 2(20) + 40 = 40 + 40 = 80°
∠ 2 = 2y + 40 = 2(30) + 40 = 60 + 40 = 100°
∠3 = x + 2y = 20 + 2(30) = 20 + 60 = 80°
Given:
Consider the inequality is 
and its solution set is 
.
To find:
The statement that verify the solution set.
Solution:
Any value into the inequality form the solution set , will create a true statement and any value into the inequality not form the solution set , will create a false statement.
To verify the solution set set, we need to put any value form solution set into the given inequality.
Substituting a value into the inequality from the solution set, such as -2, will create a true statement.
Therefore, the correct option is A.
