Answer:
B. (-7 +/-√33) / 4
Step-by-step explanation:
2x2 + 7x + 2 = 0
x = [-7 +/- √(7^2 - 4*2*2)] / 2*2
x = -7/4 +/- √(33) / 4
= (-7 +/-√33) / 4
Y=40x+100 and the second question is y=1.69x
Answer:
Step-by-step explanation:
18 + x ≤ 28
x ≤ 28 - 18
x ≤ 10
1 ≤ x ≤ 10
<span>5x - 3y= -15
3y = 5x + 15
y = 5/3 x + 5
answer
slope m = 5/3
y intercept = 5</span>
Answer:
f(x) + g(x) = x² - 10x + 9
General Formulas and Concepts:
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = x² - 11x + 18
g(x) = x - 9
<u>Step 2: Find f(x) + g(x)</u>
- Substitute: f(x) + g(x) = x² - 11x + 18 + x - 9
- Combine like terms (x): f(x) + g(x) = x² - 10x + 9
