Answer:
A. 1.65 k = 48
B. 105
Step-by-step explanation:
- If we name "k" the amount of apples that Kayla has, and "r" the amount of apples thata Richard has, we know that r + k =48 (the two of them together have 48 apples).
- In addition, we know that Kayla has 35% more apples than Richard. This means that k (1-0.35) = r (the apples of Richard are 0.35 % smaller than the apples of Kayla). Then 0.65 k = r
- Then, taking these two considerations together, r + k= 48 and 0.65 k= r, imply 0.65 k + k = 48 (I just replace the second equation into the first one). Which finally means that k= 29 (and r = 19 because r+ k=48).
- If Kayla has 162 apples, and according previous statements, she has 35% more apples than Richard, this means that 0.65 k= r, therfore if k=162, r= 162 x 0.65 = 105 (Richar has 105 apples).

Answer:
Step-by-step explanation:
Remember when you divide fractions, you need to get the reciprocal of the divisor and multiply. So your first simplification would be:
Next we factor what we can so we can further simplify the rest of the equation:
We can now cancel out (x+2)
Next we factor out even more:
We cancel out x-4 and reduce the 3 and 6 into simpler terms:
And we can now simplify it to:
Answer:
First graph
Step-by-step explanation:
Start by determining the y-intercept. Letting x = 0 yields f(0) = 2(1) = 2. This exponential graph must pass through (2, 0). This eliminates both the second and the fourth answer choices.
Looking at the first graph, we see that (1, 6) is on the graph. Does this agree with f(x) = 2(3)^x evaluated at x = 1? Is f(1) = 2(3)^1 = 6? YES. So the first graph is the correct one for f(x) = 2(3)^x.
