Answer:

1. 8

Explanation: 5x + 20(.50)=50

5x + 10=50. Now do 50-10 to get 40. So,

5x=40. Now divide 40/5 to get 8.

2. .5

5(8) + 20x=50. Now do 5*8

40 + 20x=50. Now, 50-40 to get

20x=10. And divide 10/20 to get .5

Answer:

1. x = 8

2. y = 1/2

Step-by-step explanation:

1. Plug the function

5x + 20(0.50) = 50

= 5x + 10 = 50

Subtract 10 from both side

= 5x = 40

Divide 5 on both sides

= x = 8

2. Plug in the function

5(8) + 20y = 50

= 40 + 20y = 50

Subtract 40 on both sides

= 20y = 10

Divide 20 both sides

= y = 10/20 | 1/2

ANTONII [103]

Step-by-step explanation:

There is a total amount of vehicle of 100

which is good because now you can say 73% is cars 16% is small trucks 6% is large trucks and 2% motorcycle and 3% bicycle. Adding the trucks (small 16, large 6) gives us 24% so you can do 100% - 24% and get 74%. Thanks and goodbye!

(f·g)(x) is x^5 - 5x^4 + 4x³ - x² + 5x - 4

Step-by-step explanation:

Step 1: Given, f(x) = x² - 5x + 4 and g(x) = x³ - 1 Find (f·g)(x)

(f·g)(x) = f(x)·g(x) = (x² - 5x + 4)(x³ - 1)

= x^5 - 5x^4 + 4x³ - x² + 5x - 4

= x^5 - 5x^4 + 4x³ - x² + 5x - 4

PLZ HELP, GIVNG BRAINLIEST!! Look at the pic to answer the question's both parts.

zhuklara [117]

Answer:

see explanation

Step-by-step explanation:

Given

(a + bi)(a - bi) ← expand using FOIL

= a² - abi + abi - b²i² → i² = - 1

= a² + b²

Since a and b are any real numbers, then

a² + b² is a real number

When a complex number is multiplied by its conjugate the result is always real.

For a certain strain of bacteria, r, is 0.825 (compounded continuously) when t is measured in days. How long will

fgiga [73]

Answer:5.48 days

Step-by-step explanation:

Given

Initial amount of bacteria $x_o=20$

Final Population of bacteria $x=2000$

$r=0.825$

Using formula

$x=x_o(2)^{\frac{T}{r}}$

where T=time in days

$2000=20(2)^{\frac{T}{0.825}}$

$100=2^{\frac{T}{0.825}}$

Taking log both side

$\log_{10} (100)=\log _{10} (2^{\frac{T}{0.825}})$

$2=\frac{T}{0.825}\log _{10}2$

$T=\dfrac{2\times 0.825}{\log 2}$

$T=5.48\ days$
