The vertex of this parabola is at (2, -4). When the y-value is -1, the x-value is 3. What is the coefficient of the squared term
rjkz [21]

Answer:

3

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (2, - 4) , thus

y = a(x - 2)² - 4

To find a substitute (3, - 1 ) into the equation

- 1 = a(3 - 2)² - 4 ( add 4 to both sides )

3 = a

Thus

y = 3(x - 2)2 - 4 ← equation in vertex form

   = 3(x² - 4x + 4) + 4

    = 3x² - 12x + 12 + 4

     = 3x² - 12x + 16 ← equation in standard form

with coefficient of x² term = 3

PLEASE HELP! WILL NAME BRAINLIEST!!
lbvjy [14]

Answer:

Y = 60 degrees and X = 12

Step-by-step explanation:

x+3 and 15 are congruent so x+3 = 15, 12+3 = 15 therefore x = 12

y = 60 vertically opposite angles are equal. :D

A group of friends go out for lunch. If they order 2 hot dogs and 4 cheeseburgers, the bill will
Trava [24]

Answer:

$2.75 = cost of a hot dog

$4.50 = cost of a cheeseburger

Step-by-step explanation:

Let x = cost of a hot dog

     y = cost of a cheeseburger

(1)      2x + 4y = 23.5           (2)    5x + y = 18.25    

                                                           y =  18.25 - 5x

        2x +4(18.25 - 5x) = 23.5

         2x + 73 - 20x = 23.5

         -18x + 73 = 23.5

                  -18x = -49.5

                       x = 2.75                       y = 18.25 - 5(2.75)

                                                           y = 18.25 - 13.75

                                                           y = 4.50

$2.75 = cost of a hot dog

$4.50 = cost of a cheeseburger
