7 0

Well it actually you can tell the answer, the answer will be 4x7=28
If you mean by another way then is: X/7less than or equal to 4
well then is 7x=?

X hour and 7 dollars per hour

x = hour

7(x) is your function

thank you for Anlian for pointing it out.. there is 4 hours

so x = 4

plug in 4 in x. 7(4)

7 x 4 = 28

28 is your answer

hope this helps

Decide if the function is an exponential growth function or exponential decay function, and describe its end behavior using limi

____ [38]

Answer:

The answer is (d)

Exponential decay function

$\lim_{x \to -\infty} f_x=0$

$\lim_{x \to \infty} f_x= \infty$

Step-by-step explanation:

∵ y = 0.8^x

∵ 0.8 < 1

∴ 0.8^x is decreasing ⇒ exponential decay function

Ex: 0.8^-4 = 2.441 ⇒ 0.8^4 = 0.4096

when x increase the value of 0.8^x decrease

$\lim_{n \to -\infty} f_x=0.8^{-\infty} = \frac{1}{0.8^{\infty}}=0$

$\lim_{x \to \infty} f_x=0.8^{\infty}=\infty$

∴ The answer is (d)

Bob can stamp all envelopes in the office in 5 hours and John can do the same job in 7 hours. How long will it take two of them

Delvig [45]

Answer:

<u>Bob and John can finish the job together in approximately 2.92 hours or 2 hours and 55 minutes</u>

Step-by-step explanation:

Let's recall that the formula for solving this kind of problems is:

T/A + T/B = 1, where T = time working together, A = the time for person A working alone, and B = the time for person B working alone.

Now, replacing with the values we have:

T/5 + T/7 = 1

35 is the Lowest Common Multiple of 5 and 7

5T + 7T = 35

12T = 35

T = 35/12

T = 2.92 (Rounding to the next hundredth) and 0.92 * 60 ≅ 55

T ≅ 2.92 hours (Around 2 two hours and 55 minutes)

Triangle EFG has vertices E(-3, 1), F(1, 1), and G(4, 5). Find the coordinates of the image of point F

Sloan [31]

Answer:

(1,-1)

Step-by-step explanation:

if its asking for a reflection on the x-axis, change the y's to the opposite of what it is.

Example, (5,6) change it to (5,-6)

its the same thing for the reflection on the y-axis

(7,-8) change it to (-7,-8)
