New cordinates are formed by adding 7 in x and subtracting 2 from y
A(−2, 2) =A ' (-2 +7 , 2 - 1 ) = A' (5,1)
B(−2, 4) = B' (-2 + 7 , 4 -1 )= B' (5,3)
C(2, 4) = C' (2 + 7 , 4 -1 )= C' (9,3)
<span>D(2, 2) D' (2 + 7 , 2 -1 ) = D' ( 9 , 1)</span><span>

Answer:
Prime factorization of 50 is 2 x 5 x 5 or 2 x 5^2
Step-by-step explanation:
-30= 5 (x+1 )
-5 from 5= 0
-5 from -30= -35
-35= (x+1)
1/-35= -35
Answer:
The length of the ramp is x = AC = 10.35 feet
Step-by-step explanation:
From the ΔABC
AC = x = length of ramp
BC = 10 feet
°


x = 10.35 feet
Therefore the length of the ramp is x = AC = 10.35 feet
Answer:
6 L
Step-by-step explanation:
Given two solutions:
1st solution is 90% saline solution. Let the volume of this solution be
litres.
2nd solution is 50% saline solution. Volume of this solution = 4 L
Resultant solution is 74% saline.
To find:
The volume of 1st solution = ?
Solution:
Total volume of the 74% saline mixture = (4+
) Litres
We can write equation here, as per the percentage of saline in the mixtures.
90% of
L + 50% of 4 L = 74% of (
+4)

Therefore, the volume must be <em>6 L</em>.
