Answer:
vertex = (- 2, 6)
Step-by-step explanation:
Given f(x) then f(x + a) represents a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Here a = 5 , thus a horizontal translation left by 5 units.
Thus
vertex of g(x) = (3 - 5, 6 ) = (- 2, 6 )
Answer: 5+7=2x
Step-by-step explanation:
3/2. you but as y over x and subtract the y’s then the x’s so -2-4 over -1-3 = -6/-4= 3/2
Answer:
<em>x = 7.5 cm </em>
Step-by-step explanation:
ΔBCA ~ ΔECD ⇒ the corresponding sides are proportional.
= 
AC = 4 + 6 = 10 cm
= 
⇔ 10x = 6(x + 5) ⇒ <em>x = 7.5 cm</em>
