Step-by-step explanation:
.3f+1 = .2f-4.5
1. Subtract .2f both sides
.1f+1 = -4.5
2. Subtract 1 from both sides
.1f = -5.5
3. Divide .1 both sides
f = -55
To check plug in -55 to all the f’s and both sides should be equal.
Hope this helps!
Answer:
Factoring
Step-by-step explanation:
(x+4)² = 15
x² + 8x + 16 = 15
x² + 8x + 1 = 0
![x = \frac{ - 8 + \sqrt{64 - 4} }{2} = - 4 + \sqrt{15} \\ \\ x = \frac{ - 8 - \sqrt{64 - 4} }{2} = - 4 - \sqrt{15}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B%20-%208%20%2B%20%20%5Csqrt%7B64%20-%204%7D%20%7D%7B2%7D%20%20%3D%20%20-%204%20%2B%20%20%5Csqrt%7B15%7D%20%20%5C%5C%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B%20-%208%20-%20%20%5Csqrt%7B64%20-%204%7D%20%7D%7B2%7D%20%20%3D%20%20-%204%20-%20%20%5Csqrt%7B15%7D%20)

The pictures too blurred, can you write it out?
Answer:
C
Step-by-step explanation:
Line A is Parallel to Line B
Line C intersects Line A and B
Right now the dirt bike is worth $500. Next year it will be worth 15% less, or 85% of the current value (because currently it's at 100%, so you would subtract the 15%). To find 85% of the dirt bike's value, you would take $500 and multiply by 85% (or 0.85). This would give you $425 after 1 year. You'd take $425 and multiply that by 85% for the next year, and continue until you reached 5 years of the value decreasing. Does this help?
