Answer:
A = 2.37500
B = 8.5
Step-by-step explanation:
Explanation A - 19 divided by 8 is 2.37500
Explanation B - 34 divided by 4 is 8.5
Answer:
- (4, 0) and (-2, 0)
- (1, -9)
- (0, -8)
Step-by-step explanation:
Finding the x-intercepts :
- y-value of the x-intercept is 0
- 0 = (x - 4)(x + 2)
- x - 4 = 0 ⇒ x = 4
- x + 2 = 0 ⇒ x = -2
- The x-intercepts are : (4, 0) and (-2, 0)
Finding the vertex :
- Expanding the function f
- f(x) = (x - 4)(x + 2)
- f(x) = x² - 4x + 2x - 8
- f(x) = x² - 2x - 8
- Vertex = (h, k)
- h = -b/2a = -(-2)/2(1) = 1
- k = (1)² - 2(1) - 8
- k = 1 - 2 - 8 = -9
- The vertex is : (1, -9)
Finding the y-intercept :
- Substitute x = 0 in the function
- f(0) = 0² - 2(0) - 8
- f(0) = -8
- The y-intercept is : (0, -8)
What was your question that was never answered?
I think it is C. but Im not positive
Answer:
Your answer is B
Step-by-step explanation:
Take 300 and subtract it by 99 you'll get 201
3 times 67 is 201
Which is why your answer is B!
