Answer:
he invested $10,000 at 7% and $12,000 at 6%
Step-by-step explanation:
- There are 2 equations that appear from this problem
- X+Y=22,000 and 0.07x + 0.06y = 1420
- Lets start by simplifying X+Y=22000
Y = 22000 - x
- now plug this into the Y value for the other equation
0.07x + 0.06(22000-x) = 1420
0.07x + 1320 -0.06x = 1420
0.01x = 100
X = 10000
- now plug 10000 into x for the simplified equation
Y = 22000 - 10000
Y = 12000
Answer:
- 32
- 400
Step-by-step explanation:
Lets start by defining the numbers in the equation.
This equation is in slope-intercept form meaning that it is y=mx+b or y = b+mx they are both the same
In slope-intercept form,
- m = slope or rate
- and b = y-intercept
Th equation is y=400+32x so now we know
For the first question the change per minute is the rate so it is <u>32.</u>
For the second question the starting amount is the same as the y-intercept so it is <u>400.</u>
Answer:
what are you doing
Step-by-step explanation:
45.3297 rounded to the nearest tenth is 45.3
3 is in the tenths place, so you look at the number to the right of it. If that number is 5 or more, you round up. If the number is 4 or less, you round down. So you round 45.3297 down to 45.3
