Answer:
17
Step-by-step explanation:
if f(2)=12
f(3)=5(3)+2
f(3)=15+2
f(3)=17
Let's solve your inequality step-by-step.
5x+38<4(2−5x)
Step 1: Simplify both sides of the inequality.
5x+38<−20x+8
Step 2: Add 20x to both sides.
5x+38+20x<−20x+8+20x
25x+38<8
Step 3: Subtract 38 from both sides.
25x+38−38<8−38
25x<−30
Step 4: Divide both sides by 25.
<u>25x</u> <u>-30</u>
25 < 25
25
x< <u>−6</u>

Answer:
2 miles
Step-by-step explanation:
15 miles - 9 miles = 6 miles
12 laps / 6 miles = 2 miles
This is a polynomial with more than 2 as a degree. Using Descartes Rule of Signs:
f(x) = x⁶ + x⁵ + x⁴ + 4x³ − 12x² + 12
Signs: + + + + − + 2 sign changes ----> 2 or 0 positive roots
f(−x) = (−x)⁶ + (−x)⁵ + (−x)⁴ + 4(−x)³ − 12(−x)² + 12 f(−x) = x⁶ − x⁵ + x⁴ − 4x³ − 12x² + 12
Signs: + − + − − + 4 sign changes ----> 4 or 2 or 0 negative roots
Complex roots = 0, 2, 4, or 6
Answer:
The answer is $86 in all.
Step-by-step explanation:
What you first do is make the problem into a equation which would be
($25 + $25) + ($16 + $16)
or if you are at a more advance level it would be
2($25 + $16)
in word form it would be , add $25 and $16 two times for a total of $86 in total.
