Choose the graph that represents the following system of inequalities: y ≤ −3x + 1 y ≤ 1 over 2x + 3 In each graph, the area for
Vanyuwa [196]

The graph that represents the inequality has been shown in the attachment.

<h3>How to solve for the graph</h3>

We have these equations

y ≤ −3x + 1

y ≤ x + 3

We remove the inequality sign from both of these equations

y = −3x + 1

y = x + 3

−3x + 1  = x + 3

such that

x = -0.5

we use this value for x in any of the equations

x + 3 = -0.5 + 3

= 2.5

the point of intersection is at 2.5, -0.5

we test for the origin. 0,0

3x + 1

= 3*0 + 1

= 1

for  x + 3

0+3 = 3

This is 0≤1 and 0≤3

Hence the graph should be shaded to the origin.

Answer:

See below ↓

Step-by-step explanation:

19.

  • \frac{x-1}{2} - \frac{x-3}{5} - \frac{x-7}{10} + \frac{x-2}{5}
  • \frac{5(x-1)-2(x-3)-(x-7)+2(x-2)}{10}
  • \frac{5x-5-2x+6-x+7+2x-4}{10}
  • \frac{4x+4}{10}
  • \frac{2x+2}{5}

20.

  • \frac{2x+3}{2x} + \frac{x+3}{4x} - \frac{18x+6}{8x^{2} }
  • \frac{4x(2x+3)+2x(x+3)-(18x+6)}{8x^{2} }
  • \frac{8x^{2} +12x+2x^{2} +6x-18x-6}{8x^{2} }
  • \frac{10x^{2}-6}{8x^{2} }
  • \frac{5x^{2}-3}{4x^{2} }

Write an equation to model growth or decay in the following scenario. A stock is declining at a rate of 25% of its value every 2
yawa3891 [41]

The exponential function that models this situation is:

y(t) = 225(0.75)^{\frac{t}{2}}

------------------------------------------

A decaying exponential function has the following format:

y(t) = y(0)(1 - r)^t

In which:

  • y(0) is the initial value.
  • r is the decay rate, as a decimal.

In this problem:

  • The stock started at $225, thus y(0) = 225.
  • Declines at a rate of 25% every 2 weeks, thus r = 0.25, t = \frac{t}{2}

The equation is:

y(t) = y(0)(1 - r)^t

y(t) = 225(1 - 0.25)^{\frac{t}{2}}

y(t) = 225(0.75)^{\frac{t}{2}}
