The price of a four-star meal, only $5050 per couple decades ago, has since increased 400400%. The current price of a four-

Vikentia [17]

Answer:

The correct answer is C.

Step-by-step explanation:

The price of a four-star meal, only $50 per couple decades ago, has since increased 400%.

This means that if the $50 per couple is 100%(decimal 1), the current price is 100%+400% = 500%(decimal 5). So we can solve a rule of three to find the current price of a four-star meal.

1 - 50

5 - x

$x = 50*5$

$x = 250$ .

The current price of a four star meal is $250 per couple.

The correct answer is C.

Angle 2 is 2x+10 angle 4 is 4x+80 solve for x

Airida [17]

Answer:

Step-by-step explanation:

Angle 2 is 2x+10

angle 4 is 4x+80

and from the figure we can understand that when we add these 2 equations

We get

6x+ 90= 180

6x = 180 - 90= 90

6x= 90

x = 90 ÷ 6 = 15

answer = 15

Write an equation of the parabola that opens up whose vertex (−1, 2) is 3 units from the focus. (Vertex form or Parabola Form is

TEA [102]

Answer:

y2 = 4ax (opens right, a > 0)

y2 = -4ax (opens right, a > 0)

x2 = 4ay (opens up, a > 0)

x2 = -4ay (opens down, a > 0)

Vertex at (h, k) :

(y - k)2 = 4a(x - h) (opens right, a > 0)

(y - k)2 = -4a(x - h) (opens right, a > 0)

(x - h)2 = 4a(y - k) (opens up, a > 0)

(x - h)2 = -4a(y - k) (opens down, a > 0)

Equation of a Parabola in Vertex form

Vertex at Origin :

y = ax2 (opens up, a > 0)

y = -ax2 (opens down, a > 0)

x = ay2 (opens right, a > 0)

x = -ay2 (opens left, a > 0)

Vertex at (h, k) :

y = a(x - h)2 + k (opens up, a > 0)

y = -a(x - h)2 + k (opens down, a > 0)

x = a(y - k)2 + h (opens right, a > 0)

y = -a(y - k)2 + h (opens left, a > 0)

If f(x) = 2х2 + 3 and g(x) = х2 -7, find (f- а)(x).

Lerok [7]

Answer:

C. x^2 -4

Step-by-step explanation:

What you do is subtract the functions as said by

(f-g)(x).

so:

f(x)-g(x)

(2x^2+3) - (x^2 -7)

2x^2 -x^2 +3 - 7= x^2 -4
