Answer:
x = 21
Step-by-step explanation:
21 x 3 = 63 and 63 + 67 = 130 and sense there across from eachother this is correct because vertical angles are always the same measure.
Hope this helps!
Answer:
- (-1, -5), (-1/2, -3), (-1, -9)
Step-by-step explanation:
<u>The function in vertex form is:</u>
- f (x) = a(x - h)² + k, where (h, k) is the vertex
- f(x) = (x - 1)² - 3
i) y = f(x) - 2 = (x - 1)² - 3 - 2 = (x - 1)² - 5 ⇒ h = 1, k = -5
<u>Minimum point:</u>
ii) y = f(2x) = (2x - 1)² - 3 = 4(x - 1/2)² - 3 ⇒ h = 1/2, k = -3
<u>Minimum point:</u>
iii) y = 3f(x) = 3((x - 1)² - 3) = 3(x - 1)² - 9 ⇒ h = 1, k = -9
<u>Minimum point:</u>
A- 3 and 4 ... hope this helps uu
