Answer:angle A = 21 degrees

Angle B = 80 degrees

Angle C = 79 degrees

Step-by-step explanation:

The sum of the angle in a triangle is 180 degrees. This means that in triangle ABC,

Angle A + angle B + angle C = 180 degrees. Therefore,

2x + 7 + 10x + 10 + 8x + 23 = 180

2x + 10x + 8x + 7 + 10 + 23 = 180

20x + 40 = 180

20x = 180 - 40 = 140

x = 140/20 = 7

Therefore,

Angle A = 2x + 7 = 2 × 7 + 7 = 14 + 7 = 21 degrees

Angle B = 10x + 10 = 10 × 7 + 10 = 70 + 10 = 80 degrees

Angle C = 8x + 23 = 8 × 7 + 23 = 56 + 23 = 79 degrees

Y= -3x^2-24x-46 write in vertex form
mario62 [17]

ANSWER

y= -3{(x + 4)}^{2}  + 2

EXPLANATION

The given function is:

y= -3x^2-24x-46

Factor -3 for the first 2 terms.

y= -3(x^2 + 8x)-46

We add and subtract the square of the coefficient of x.

y= -3(x^2 + 8x +  {(4)}^{2} )  - - 3( {4)}^{2} -46

Factor the perfect square trinomial.

y= -3 {(x + 4)}^{2} )  + 48 -46

The vertex form is:

y= -3{(x + 4)}^{2}  + 2
