Mathematics
1 answer:
Goshia [24]3 years ago

Answer:

C

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) = (5, 2), thus

y = a(x - 5)² + 2

To find a substitute (4, - 3) into the equation

- 3 = a + 2 ⇒ a = - 3 - 2 = - 5

y = - 5(x - 5)² + 2 ← in vertex form

Expand (x - 5)² and distribute by - 5

y = - 5(x² - 10x + 25) + 2

  = - 5x² + 50x - 125 + 2

  = - 5x² + 50x - 123 ← in standard form

Problem Page A table of values of a linear function is shown below. x −1 0 1 2 3 y −6 −8 −10 −12 −14 Find the slope and y -inter
Ivenika [448]
When x=0, y=-8, so that is the y-intercept.

When x increases by 1, y decreases by 2, so the slope is -2.

The equation of the function is
.. y = -2x -8

Answer:

1)(2x + y \:  \:  \: 2) = (1 \:  \: x - y) \\ so \: compare \: 2x + y = 1...(1) \\ 2 = x - y....(2) \\ 2x + y = 1...(1) \\ x - y = 2....(2) \\ (1) + (2) \\ 3x + 0y = 3 \\ x =  \frac{3}{3}  = 1 ....(3)\\  \\ put \: (3)in \: (1) \\ 2 \times 1 + y = 1 \\ y = 1 - 2 \\ y =  - 1 \\ here \: x = 1 \\ y =  - 1 \\ 2)(x  + 2y \:  \:  \: 3) \: and \: ( - 1 \:  \:  \: 2x - y) \\ here \: x + 2y =  - 1...(1) \\ 2x - y = 3...(2) \\ (2) \times 2 =  > 4x - 2y = 6...(3) \\ x + 2y =  - 1....(1) \\ (1) + (3) \\ 5x + 0y = 5 \\ x =  \frac{5}{5}  = 1....(3) \\ put \: (3) \: in \: (1) \\ 1 + 2y =  - 1 \\ 2y =  - 2 \\ y =  \frac{ - 2}{2}  =  - 1 \\ here \: x = 1 \\ and \:  \\ y =  - 1 \\ thank \: you
