Vertical reflection over the x-axis, shrink of 1/3, right 3, up 2
Answer:
x=−5
Step-by-step explanation:
Subtract 2525 from both sides of the equation.
x2+10x=−25x2+10x=-25
To create a trinomial square on the left side of the equation, find a value that is equal to the square of half of bb.
(b2)2=(5)2(b2)2=(5)2
Add the term to each side of the equation.
x2+10x+(5)2=−25+(5)2x2+10x+(5)2=-25+(5)2
Simplify the equation.

Raise 55 to the power of 22.
x2+10x+25=−25+(5)2x2+10x+25=-25+(5)2
Simplify −25+(5)2-25+(5)2.
Tap for more steps...
x2+10x+25=0x2+10x+25=0
Factor the perfect trinomial square into (x+5)2(x+5)2.
(x+5)2=0(x+5)2=0
Set x+5x+5 equal to 00 and solve for xx.
Tap for fewer steps...
Set the factor equal to 00.
x+5=0x+5=0
Subtract 55 from both sides of the equation.
x=−5
if y=2x then the y for -1 would be -2
so your first coordinates are )-1, -2) and so on so forth
second coordinates are (0,0) third are (1,2) fourth are (3,6) fifth are (4,8)
not sure if that's what you had or not but that should be about right.
