9514 1404 393

Answer:

  A

Step-by-step explanation:

The axis of symmetry of quadratic ax²+bx+c is x=-b/(2a). For the given equation, the axis of symmetry is ...

  x = -4/(2(3/2)) = -4/3

The only graph with its vertex at x=-4/3 is graph A.

_____

<em>Additional comment</em>

You can also make the correct choice by evaluating the equation at a couple of different values of x. Convenient ones are x= -1, or 0, or +1. The value at x=0 is the y-intercept, (0, -2), which seems to be a point on all of the graphs. The value at x=1 is 3/2+4-2 = 3.5, which looks like it is only seen on graph A.

You have a balance of $4,600 on your credit card. The interest rate is 12% (1% per month). The late payment fee is $40.
MariettaO [177]

Answer:

$86

Step-by-step explanation:

first you gotta find the interest

4,600 * 1% = 46

so the interest is $46

then you add the interest and late fees together to get the payment for the month

46 + 40 = $86

your total cost is $86

Answer:

-2/3= x

Step-by-step explanation:

<u><em>square all the terms on both sides to get rid of the radicals:</em></u>

1^{2} + (\sqrt{1-x} )^{2} = (\sqrt{2x+4}) ^{2}

<u><em>exponent 2 and the radical cancel each other:</em></u>

1 + 1 - x = 2x + 4

2 - x = 2x + 4

<u><em>like terms on each side ( when you move one term tp the other side, it changes its sign ):</em></u>

2-x = 2x+4

2-4 = +x +2x

-2 = 3x

<u><em>now to keep the x alone, divide both sides by 3:</em></u>

-2/3 = 3x/3

-2/3= x
