income =$1200
expenditure=$450
saving=$1200-$450
=$750
ratio of income to expenditure is 1200:450
=8:3
ratio of savings to income is 750:1200
=5:8

Answer:
Range: (-∞, 0]
General Formulas and Concepts:
<u>Algebra I</u>
- Range is the set of y-values that are outputted by function f(x)
Step-by-step explanation:
When we graph the equation, we should see that our y-values span from -∞ to 0. Since 0 is a closed dot, it is inclusive in the range:
(-∞, 0] or y ≤ 0
Answer:
8 is the slope
Step-by-step explanation:
Because the amount per 1 thing is the slope
729-243=486
486×3=1458
1458+729=2187(x=7)
1458×3=4374
4374+2187=6561(x=8)
4374×3=13122(average rate of change for interval 8 to 9)
13122+6561=19683(x=9)
Ans: B
12 x 5.2
Estimate:
since 5.2 is about 5, we can estimate this to:
12 x 5 = 60
Find the Product:
12
<u> x 5.2
</u> 2 4
<u> + 6 0 0
</u> 6 2 4
now add the decimal back in. In the original problem there is one decimal place (the .2 in 5.2) so we move the decimal place one over in our product
624 becomes 62.4
