Clara lends half her collection of formal attires to her sister, Susan. Clara then buys four more attires. If she has 12 attires
alukav5142 [94]

Answer:

16

Step-by-step explanation:

Number of attires Clara has initially = x

lends half her collection of formal attires to her sister

Attires remaining after lending = Number of attires Clara has initially - attires she lent her sister

= x - 1/2x

= 1/2x

Clara then buys four more attires

= 1/2x + 4

If she has 12 attires now

12 = 1/2x + 4

12 - 4 = 1/2x

8 = 1/2x

x = 8 ÷ 1/2

= 8 × 2/1

= 16

x = 16

Number of attires Clara has initially = x = 16

Which of the following exponential regression equations best fits the data shown below
Art [367]

Answer:

(D) 8.46\cdot 3.51^x

Step-by-step explanation:

One could run this on a computer and verify the best fit through brute force. The more elegant way is, as usual, to think: What are special values of x for an exponential function? Zero, for starters - anything to the power of zero is 1. The function value for x=0 in the table is 10. Which choices A through D are close to 10 for x=0? Well, (C) and (D), the rest is too far. Next, what is the function value for the next easy one, x=1? The table says 30. Which of (C) and (D) is close to 30 for x = 1. It turns out we can safely exclude (C) because 10.84*1.77 is about 19 and that's way too far from 30. Let's check (D): 8.46*3.51=29.7 - that's quite close. Since there is no other candidate left, I bet my money on (D). Feel free to verify closeness for the other values of x if you are unconvinced yet.

Which shows the equation y + 4 = 2(x – 1) written in standard form? –2x + y = –5 –2x + y = –6 y = 2x – 6 y = 2x – 5
Cloud [144]
Y + 4 = 2(x - 1)
y + 4 = 2x - 2
-2x + y = -2 - 4 = -6
-2x + y = -6
