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
No.
This is because the y value of 1 repeats itself, which never happens in an exponential function. This function is likely quadratic, which forms a parabola.
8x+6+4= 3x- 2x- 4 is the correct step
Answer:
480 cm²
Step-by-step explanation:
New side lengths:
80% of 30 cm = 0.8% × 30 cm = 24 cm
80% of 25 cm = 0.8 × 25 cm = 20 cm
area = length × width
area = 24 cm × 20 cm
area = 480 cm²
27000 is halfway because the difference between them is 500. 500 divided by 2 is 250. 26750plus 250 is 27000
