It's A. All you have to remember here are your rules of translations. If there is side to side movement within a parabola it will be indicated within a set of parenthesis with the x coordinate. If there is no set of parenthesis with the x there is no side to side movement. The quantity $(x+3) ^{2}$ tells us that the vertex has moved left 3 units.

In the question, "35 is what percent of 40?" what is the 35?

schepotkina [342]

Answer:

35 is the 'is' and 40 is the 'of'

Step-by-step explanation:

is/of = %/100

35/40 = x/100

cross-multiply to get:

40x = 3500

x = 3500/40

x = 87.5

Help!! <br>2x+3 (x-4)=x-20

prohojiy [21]

Remember you can do anything to an equation as long as you do it to both sides

2x+3(x-4)=x-20
first distribute
2x+3(x)+3(-4)=x-20
2x+3x-12=x-20
5x-12=x-20
minus x both sides
4x-12=-20
add 12 to both sides
4x=-8
divide both sides by 4
x=-2
