Answer:
D
Step-by-step explanation:
Current coordinate of R : ( 1,5 )
Applying translation with rule (x,y) --> (x+1 , y-1)
Coordinate after translation ( 1 , 5 ) ==> ( 1 + 1 , 5 - 1 ) ==> ( 2 , 4 )
applying dilation with scale factor of 3 , to apply dilation multiply x and y values by scale factor which is 3
Coordinate after dilation ( 2 , 4 ) ==> ( 2 × 3 , 4 × 3 ) ==> ( 6 , 12 )
The final coordinate is ( 6 , 12 )
Answer:
17
Step-by-step explanation:
131-12=3x+4x+12-12
119= 3x+4x
119=7x
119/7=7x/7
17=x

⟨1⟩
<u>Solution</u><u>:</u>
In ∆RQS and ∆DQS, we have
- RQ = SD [Given]
- RS = QD [Given]
- QS = QS [Common side]
∴ ∆RPQ =~ ∆DQS [By SSS congruence rule]
⟨2⟩
Solution:
In ∆UVW and ∆KMV, we have
- VW = VM [Given]
- ∠UVW = ∠KMW [vert. opp ∠s]
- VW = VK [Common side]
∴ In ∆UVW =~ ∆KMV [By SAS congruence criterion]
Answer:
The Civil Rights Act of 1964: A Long Struggle for Freedom. ... The act did not fulfill all of the goals of civil rights activists. It would take further grassroots mobilization, judicial precedent, and legislative action to guarantee civil rights for African Americans.
