<span>A.) y = 0.3(2)x
These are exponential decay</span>
Part A: David wrote 0.003 + 0.0001 instead of <span>0.03 + 0.001
Part B: T</span>he 1 should be in the thousandths place
Hope this helps, make sure to count each place from right after the decimal which is the tenths place, then hundredths, etc.
Answer:
My answer is 20ft I'm not really sure but hope this helps
Given equations are;<span>
2a + 3b = -1 ..................equation 1
3a + 5b = -2 ....................equation 2</span>
Now multiply equation 1 with (-3)
The equation will be;
-6a -9b = 3 …………………..equation 3
Now multiply equation 2 with (2)
The equation will be;
6a + 10b = -4 ……………..equation 4
Now add equation 3 and equation 4
-6a – 9b = 3
<span>6a + 10b = -4</span>
<span>------------------------------</span>
0a + b = -1
b = -1
Now put the value of b in equation 1
2a + 3(-1) = -1
2a -3 = -1
2a = -1+3
2a = 2
a=1
Thus the solution is (a,b) = (1,-1)

2/3y = 18
y = 18 / (2/3)
y = 18 * 3/2
y = 54/2
y = 27 <==
