Answer:

x=-4.992 and x=-0.434

Step-by-step explanation:

we have    

\frac{\sqrt{3x+15}}{5}=2^{x}

we can divide the equation above into two equations

so

y=\frac{\sqrt{3x+15}}{5} ----> equation A

y=2^{x} ----> equation B

Solve by graphing

The solutions of the system are the x-coordinates of the intersection points both graphs

using a graphing tool

The solutions are x=-4.992 and x=-0.434

see the attached figure

Please help Which of the following inequalities is graphed on the coordinate plane?
Gekata [30.6K]

Answer:

The inequality which represents the graph is y ≤ -2x + 1 ⇒ A

Step-by-step explanation:

To solve the question you must know some facts about inequalities

  • If the sign of inequality is ≥ or ≤, then it represents graphically by a solid line
  • If the sign of inequality is > or <, then it represents graphically by a dashed line
  • If the sign of inequality is > or ≥, then the area of the solutions should be over the line
  • If the sign of inequality is < or ≤, then the area of the solutions should be below the line

Let us study the graph and find the correct answer

∵ The line represented the inequality is solid

∴ The sign of inequality is ≥ or ≤

→ That means the answer is A or B

∵ The shaded area is the area of the solutions of the inequality

∵ The shaded area is below the line

∴ The sign of inequality must be ≤

→ That means the correct answer is A

∴ The inequality which represents the graph is y ≤ -2x + 1

If storm has 3 bars she needs 22 bars but one bar equals 4 ores how many ores does she need?
oee [108]

Answer:

19 bars =<u> 76 more ores.</u>  22 bars = <u>88 total ores.</u>

Step-by-step explanation:

y = 4x

(4 times a number. Ex: x could be 98740757 or 2, it doesn't matter.)

1 b = 4 o

3 b = 12 o

22 - 3 = 19 b

19 b = 76 o (more)

22 b = 88 o (total)
