A. 3y = 24
Step-by-step explanation:
Answer:
Vertex is (-a, -6), where a ≠ 0.
General Formulas and Concepts:
<u>Algebra I</u>
- Coordinates (x, y)
- Quadratics
<u>Algebra II</u>
Vertex Form: y = a(bx - h)² + k
- <em>a</em> is the vertical scale factor
- <em>b</em> is the horizontal scale factor
- (h, k) is the vertex
Step-by-step explanation:
<u>Step 1: Define</u>
y = -3(x + a)² - 6
↓ <em>Identify variables</em>
<em>a</em> = -3
<em>b</em> = 1
(h, k) = (-a, -6)
Answer:
Step-by-step explanation:
The angles <JKL, <EKL, and <JKE form a full angle which means their sum is equal to 360:
134 + 21x + 6 + 5x = 360 add like terms
140 + 26x = 360 subtract 140 from both sides
26x = 220 divide both sides by 26
x = 8.4 approximately
to find the angle m<JKL replace x with the value we found.
