Mathematics
1 answer:
Alex787 [66]3 years ago

Answer:

option (3)

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

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

Given

f(x) = x² - 12x + 7

Using the method of completing the square

add/subtract ( half the coefficient of the x- term )² to x² - 12x

f(x) = x² + 2(- 6)x + 36 - 36 + 7

      = (x - 6)² - 29

with vertex (h, k ) = (6, - 29 )

Each figure shows a triangle with one of its angle bisectors.
OLga [1]

Answer:

m<2 is 17 degrees

Step-by-step explanation:

We can see that the angle at the vertex E was bisected to give two different but equal angles

Thus, we have it that;

2x + 7 = 4x-3

4x-2x = 7+ 3

2x = 10

x = 10/2

x = 5

so m<2 = 4(5) -3 = 20-3 = 17 degrees

Answer:

a) y = \frac{7}{17}

b) x = 4

Step-by-step explanation:

a) \frac{3y+2}{5} =4y-1

3y + 2 = 20y - 5

2 = 20y - 3y - 5

2 = 17y - 5

2 + 5  = 17y

7 = 17y

y = \frac{7}{17}

b) x² + 5 = 21

x² = 21 - 5

x² = 16

x = √16

x = 4
