Answer:

40

Step-by-step explanation:

Let the number of 20cent coins be 'x'

Then, 10cent coins are 'x + 12'

Total amount = $5.4 = 540 cents

20(x) + 10(x + 12) = 540

20x + 10x + 120 = 540

30x = 540 - 120

30x = 420

x = 420/30

x = 14 (14 20cent coins)

x + 12 = 26 (26 10cent coins)

Total coins = 14 + 26 = 40

<h3>Answer:</h3>
  • x-intercept: 82.75
  • y-intercept: -2.15
<h3>Step-by-step explanation:</h3>

To find the x-intercept, set y=0 and solve.

... 0 = log(12x +7) -3

... 3 = log(12x +7) . . . . add 3

... 1000 = 12x +7 . . . . take the antilog. (10^3 = 1000)

... 993 = 12x . . . . . . . .subtract 7

... 82.75 = x . . . . . . . . divide by 12

To find the y-intercept, set x=0 and solve.

... y = log(12·0 +7) -3

... y = log(7) -3 . . . . . . simplify

... y ≈ 0.85 -3 = -2.15 . . . . use a calculator for the log function
