Hello from MrBillDoesMath!
Answer:
d>4
Discussion:
I understand the question is asking us to solve for "d" in the inequality:
d + 2 > 6 => subtract 2 from both sides
d + 2 -2 > 6 - 2 => as 2 - 2 = 0
d > 6 -2 = 4
If I have misunderstood the question, please tell me.
Thank you,
MrB
6000 x 0.08 x 2 = 960
answer: interest $960
hope that helps
Answer:
Average rate of car: x+3
Walking rate: x
The equation is
10/15 = x/x+3
So
x = 6
So
Average rate of car: 9 mph
Walking rate: 6 mph
Step-by-step explanation:
What we know:
12 hour period from 8pm to 8am
temperature dropped from 8°F to 16°F from 8pm to 8am
We need to find temperature at 4 am.
We can start by setting up points:
8pm is are starting point with 8°F, we can express it as (0,8), 0 represents initial time from 0 to 12 hour span.
8am is the ending point with 16°F, we can express it as (12,16), 12 represents the end time of 0 to 12 hours span.
We will use these points to find slope.
slope=m=(16-8)/(12-0)=8/12=2/3
Now, we can set up an expression to find any temperature at a specific time. Aslo, x represents the hours not the the specific time of 4am. We will use 8 since 4am is the 8th hour of the 12 hour span. Using slope of 2/3 and the y intercept of (0,8) since we were already at 8°F at the initial time of 0 we have the function:
f(x)=2/3x+8
f(8)=2/3(8)+8= 40/3≈13.3°
Divide 200k by 5k, assuming that the budget is equal to the tax rate, then 2.5%
