Shift down and right
<u>Shift 3 units down</u>
The rule is: (x,y)=> (x,y-a)
Where a is the number of units shifted down
In this case:
So, we have:
== >
<u>Shift 2 units right</u>
The rule is: (x,y)=>(x-b,y)
Where b is the number of units shifted right
In this case:
So, we have:
==>
Open bracket:
Hence, the new equation after the transformation is:
Answer:
B i think
Step-by-step explanation:
21 COINS
9 are NICKLES
all the other are pennies
21 - 9 =12
so 12 pennies
1 nickle is 5 cents so
5*9 = 45 cents so
45 + 12 = 57
so the answer is 57 cents
Answer:
x = - 2 ±
Step-by-step explanation:
Given
x² = - 4x + 3 ( add 4x to both sides )
x² + 4x = 3
To complete the square
add (half the coefficient of the x- term)² to both sides
x² + 2(2)x + 2² = 3 + 2²
(x + 2)² = 3 + 4 = 7 ← take the square root of both sides
x + 2 = ± ← subtract 2 from both sides
x = - 2 ± ← exact values
