Answer:

The answer is A) 16 units.

Step-by-step explanation:

ABC is an equilateral triangle. So all the angles are equal to 60°

m∠BCA = 2x = 60°

2x = 60

x = 30

AB = x-14         we have that x = 30

So: AB = 30-14 = 16

Write a linear equation that passes through the point (2,-9) and has a slope of -5
Anna [14]

Answer:

  • y = -5x + 1

Step-by-step explanation:

<u>Given:</u>

  • The slope m = -5 and point (2, -9)

<u>Use point slope form:</u>

  • y - y₁ = m(x - x₁), where (x₁, y₁) is the given point

<u>So the equation is:</u>

  • y - (-9) = -5(x - 2)
  • y + 9 = -5x + 10
  • y = -5x + 1

How to solve function operations
Mama L [17]
" Given f (x) = 3x + 2 and g(x) = 4 – 5x, find (f + g)(x), (f – g)(x), (f × g)(x), and (f / g)(x).1. = [3x + 2] + [4 – 5x] = 3x + 2 + 4 – 5x. = 3x – 5x + 2 + 4. = –2x + 6. (f – g)(x) 2. = f (x) – g(x)= [3x + 2] – [4 – 5x] = 3x + 2 – 4 + 5x. = 3x + 5x + 2 – 4. = 8x– 2. 3. ...= (3x + 2)(4 – 5x) = 12x + 8 – 15x2 – 10x. = –15x2 + 2x + 8. " - Google

The product of two consecutive integers is 90. Which equation can be used to find the two integers?
joja [24]
Two consecutive integers would be x and x+ 1
if you multiply them you have x(x + 1) = x^2 + x
if you want the product to equal 90 you get x^2 + x = 90
The first option is correct.
