Answer:
(-1.5, 9) midpoint of AB
Step-by-step explanation:
The midpoint of A"B" is ...
M" = (A" +B")/2 = ((-3, 1) +(4, -9))/2 = (-3+4, 1-9)/2 = (1/2, -4)
We can "undo" the reflection across the x-axis to find M'. Reflecting M" back across the x-axis negates its y-coordinate:
M' = (1/2, 4)
We can undo the translation right 2 and down 5 by translating M' left 2 and up 5.
M = M' +(-2, 5) = (1/2-2, 4 +5)
M= (-1.5, 9)
The midpoint of AB is (-1.5, 9).
Answer:
Step-by-step explanation:
Multiply both sides by d:
Expand:
+4d on both sides:
Factorise d out of the left-hand side:
Divide both sides by (3x +4):
Answer:
My infer/best guess should be about 11% of a increase
Answer:
1. 7x + 2 3/5
2. 2x-6.3
3. 27t + 36b
4. 3.5a - 9.1p
5. 8(x+7)
6. 3(x+19)
7. y= -8.9
8. n = -18
Step-by-step explanation:
1. combine like terms
2. Keep change change then combine like terms
3. distribute
4. distribute
5. have 8 in common
6. have 3 in common
7. subtract 1.6 from -7.3
8. multiply both sides by -2/3
