Answer:

Step-by-step explanation:

1. 2 + 3{(4 - 1)2}

let solve the bracket first

2+3{(3)2}

2+3(9)

2 + 27

=29

2. 3y - ( x +2)

where x = -5 and y = 3

3(3) - (-5 + 2)

9 + 5 - 2

i multiply the bracket with negative sign

9 + 3

= 12

3. 2(4x - 3) + 3x

distribute

8x - 6 + 3x

combine the like terms

8x + 3x -6

Answer: 4

Step-by-step explanation:

We know that a plane is 2 dimensional surface that extends infinitely far.

The number of points required to define a plane = 3

Here , we have 4 points A, B, C, and D.

So, the number of possible combinations of 3 points to make a plane from 4 points = C(4,3)

=4            [ C(n,n-1)=n ]

Hence, the greatest number of planes determined using any three of the points A, B, C, and D if no three points are collinear = 4.

Explain how you got the answer(:
Natali [406]
Hey there :) I'm pretty sure that your answer is D) ∠S ≅ <span>∠Y because corresponding angles of similar triangles are congruent.

I think that it is the answer because if you shift your paper around, and look at the angles from different views, you can tell that angles S and Y are congruent, or the same, because of the way that both angles are at the end of the longer sides of both triangles.

So, your answer is D!

~Hope this helped!~</span>

If f(x)=x/3 -2 and g(x)=3x^2+2x-6 find (f+g)(x)
umka21 [38]

Answer:

(f + g)(x) = 3x² + (7/3)x - 8

Step-by-step explanation:

To find (f + g)(x), you need to add both the f(x) and g(x) equations together.

f(x) = x/3 - 2 ..... which is equal to ... f(x) = (1/3)x - 2

g(x) = 3x² + 2x - 6

(f + g)(x) = ((1/3)x - 2) + (3x² + 2x - 6)          <----- Add both equations

(f + g)(x) = 3x² + (1/3)x + 2x - 2 - 6              <----- Rearrange (2 = 6/3)

(f + g)(x) = 3x² + (7/3)x - 8                           <----- Simplify similar terms
