Answer:
17.6 miles
Step-by-step explanation:
5 divided by 8 is 1.6
1.6 times 11 is 17.6
Answer:
B=-4+18r-18s
Step-by-step explanation:
move all terms not containing B to the right side of the equation. Hope this helps.
This solution is arrived at using the principles of Quadratic Functions and Inequalities. It is to be noted that the function increases at (-8, 4).
<h3>What are Quadratic Functions?</h3>
A quadratic function can be defined as that is written in the following way: f(x) = ax2 + bx + c: Where a, b, and c are numbers not equal to zero.
<h3>How do we solve the problem above?</h3>
To solve the problem f(4x - 3) ≥ f(2 - x^2), Df = (-8 , 4), we:
- Rewrite
- Collect like terms
- Expand
- Factorize, then
- Solve for <em>x</em>.
A) 4x - 3 ≥ 2 - x²
Rewrite as: x² + 4x - 2 - 3 ≥ 0
B) Collect the like terms
x² + 4x - 5 ≥ 0
C) Expand to have x² + 5x - x - 5 ≥ 0
D) Factorizing the expression we have
x(x + 5) - 1(x + 5) ≥ 0, from this we Factor away x + 5
(x - 1)(x + 5) ≥ 0
E) Solving for x we obtain: x ≥ 1 or x ≥ -5
This can also be rewritten to read:
-5 ≤ x ≤ 1
