We have that
<span>f(x)=-x+0.5
g(x)=x</span>²+3x-4
f(x)=g(x)------------> -x+0.5=x²+3x-4-------------> x²+3x-4+x-0.5=0
x²+3x-4+x-0.5=0---------------> x²+4x-4.5=0
using a graph tool
see the attached figure
the solution are the points (-4.915,0) and (0.915,0)
Answer:
Step-by-step explanation:
Ms Fowler's ratio would be 8:7 and Ms Rivera's would be 16:15, they are not equivalent because the numbers didn't come out to the same ratio when i divided them and 16 and 1 aren't divisible by the same numbers.
here are the steps i took:
1. wrote down the original ratios (16:15 and 64:60)
2. I divided all the numbers by 2 and got them reduced to 8:7 and 30:32
3. I saw that the 8:7 couldn't be divided anymore, so I left it and divided 30 by 2 and 32 by 2 and got 16:15
4. I saw that I couldn't divide those anymore so I compared the ratios and saw that they were not the same so they weren't equal.
hope this helped!
A. If the restraunt is closed, we will become rich.
<span>"The company pays $55 a day for food and lodging and $0.45 for each mile traveled" means that if she travels
m miles and is on a trip for
x days then Rita will receive:
55x + 0.45m dollars.
Rita drove 300 miles, means that m=300. Thus </span>
55x + 0.45m becomes <span>
</span>
(dollars.)
She was reimbursed $2,335 means that
.
Part A:
.
Part B:
We are given the equation 55x+135=2,335. Subtracting 135 from both sides we have:
55x=2,335-135=2,200.
Dividing both sides by 55, we get: x=2,200/55=40.
Part C: since x represents the number of days Rita spend on this trip, and x=40, then Rita spent 40 days on this trip.
