SashulF [63]3 years ago
4 0

Answer:

x = 4 , y = 4

Step-by-step explanation:

Solve the following system:

{4 x - 2 y = 8 | (equation 1)

y = (3 x)/2 - 2 | (equation 2)

Express the system in standard form:

{4 x - 2 y = 8 | (equation 1)

-(3 x)/2 + y = -2 | (equation 2)

Add 3/8 × (equation 1) to equation 2:

{4 x - 2 y = 8 | (equation 1)

0 x+y/4 = 1 | (equation 2)

Divide equation 1 by 2:

{2 x - y = 4 | (equation 1)

0 x+y/4 = 1 | (equation 2)

Multiply equation 2 by 4:

{2 x - y = 4 | (equation 1)

0 x+y = 4 | (equation 2)

Add equation 2 to equation 1:

{2 x+0 y = 8 | (equation 1)

0 x+y = 4 | (equation 2)

Divide equation 1 by 2:

{x+0 y = 4 | (equation 1)

0 x+y = 4 | (equation 2)

Collect results:

Answer: {x = 4 , y = 4

An exponentially function is expressed in the form y = axb^x . The relation represents a growth when _ and a decay when _ .
Sergio [31]

Answer:

The relation represents a growth when b>1 and a decay when 0<b<1

Step-by-step explanation:

Any function in the form f(x)= a(b^x), where a > 0, b > 0 and b not equal to 1 is called an exponential function with base b. If 0 < b < 1.  It is an example of an exponential decay. The general shape of an exponential with b > 1 is an example of exponential growth. An exponential function is expressed in the form y=a(b^x) The relation represents a growth when  b >1 and a decay when 0<b<1.

Awarding 90 Points
Amanda [17]

Answer:

  • 1090

Step-by-step explanation:

<h3>Given AP </h3>
  • a₁₂ = 62
  • a₂₀ = 102
<h3>To find</h3>
  • S₂₀
<h3>Solution</h3>
  • a₁₂ = a + 11d = 62
  • a₂₀ = a + 19d = 102

<u>Subtract the first equation from the second one:</u>

  • 8d = 40
  • d = 5

<u>Find a:</u>

  • a + 11*5 = 62
  • a = 62 - 55
  • a = 7

<u>Find the sum of the first 20 terms:</u>

  • S₂₀ = 1/2*20(a + a₂₀) = 10(7 + 102) = 10(109)= 1090
