Answer: a) 2 b)1  c)1/3 d)5/4

Step-by-step explanation:

Hi to solve this equation we simply have to replace the variable with the number given, and then isolate the variable.

  • 5x, if x= 2/5

5 x 2/5 = 10 /5 = 2

  • 5/x,if x =5

5/5= 1

In this case after replacing the number we have to simplify it.

  • 2y-1, if y =2/3

2 (2/3) -1 =

4 /3 -1 =

4/3 -3/3 = 1/3

In this case, to add fractions first we have to multiply the top and bottom numbers of the second fraction by 3, to have the same denominators.  

  • h+3/4, if h = 1/2

1/2 + 3/4 =

2/4 +3/4 = 5/4

Feel free to ask for more if it´s necessary or if you did not understand something.

5x if x= 2/5 . 5/1x 2/5= 10/5= 2

5/x = 5/5= 1

8/3_ 1 = 8/3- 3/3= 5/3

1/2+ 3/4 = 2/4+3/4= =5/4

If your starting salary is $50,000 and you receive a 4%increase at the end of every year, what is the total amount, indollars, y
Softa [21]
Answer

Total amount earned after 16 years = $93649

Explanation:

The principal, P = $50,000

Interest rate, r = 4% = 4/100

r = 0.04

The time, t = 16 years

Number of times intesrest is compounded per year, n = 1

Total amount is calculated below:

\begin{gathered} A=P(1+r)^t \\  \\ A=50000(1+0.04)^{16} \\  \\ A=50000(1.04)^{16} \\  \\ A=\$93649 \end{gathered}

Total amount earned after 16 years = $93649

Find the center, vertices, and foci of the ellipse with equation x squared divided by 400 plus y squared divided by 625 = 1
Inessa05 [86]

Answer:

x^2/400 + x^2/625

(x-0)^2/400) +(y-0^2/625)

x^2=400

X=sqrt. 400

x = 20

y^2=625

y = sqrt. 625

y= 25

a^2-c^2=b^2

sqrt 400-625 = c

20-25=c

The correct answer is c=-5

(-5,0)

(5,0)
