Answer:
132°
Step-by-step explanation:
because the lines are parallel x + 48° must be 180°
therefore x = 132°
Answer:0.3000
Step-by-step explanation: 0.3104 is the answer but not rounded the answer might not be right!
Answer:
y⁴ - 2y²
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
4y⁴ - (3y² + 3y⁴) + y²
<u>Step 2: Simplify</u>
- Distribute negative: 4y⁴ - 3y² - 3y⁴ + y²
- Combine like terms (y⁴): y⁴ - 3y² + y²
- Combine like terms (y²): y⁴ - 2y²
Answer:
After looking at your pfp and then the question I have came to a conclusion
y= 1x + 2
Im not sure if the 1 is right but the second is 2 for sure
<span>
-20 = 4a - 2b + c
-4 = c
-20 = 16a + 4b + c
4a - 2b + c = 16a + 4b + c
4a - 2b = 16a + 4b
-6b = 12a
b = -2a
-20 = 4a - 2b + c
-20 = 4a + 4a - 4
-16 = 8a
-2 = a
b = 4
c = -4
y = -2x^2 + 4x - 4
y = -2 * (x^2 - 2x) - 4
y = -2 * (x^2 - 2x + 1 - 1) - 4
y = -2 * (x^2 - 2x + 1) + 2 - 4
y = -2 * (x + 1)^2 - 2 </span>
