Answer:

x ≈ 14.30

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Trigonometry</u>

  • sin∅ = opposite over hypotenuse

Step-by-step explanation:

<u>Step 1: Define variables</u>

∅ = 39°

opposite leg = 9

hypotenuse = x

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute:                              sin39° = 9/x
  2. Multiply <em>x</em> on both sides:       xsin39° = 9
  3. Isolate <em>x</em>:                                 x = 9/sin39°
  4. Evaluate:                                 x = 14.3011
  5. Round:                                    x ≈ 14.30

Show that line passing through points (3,-2) and (-4,-2) is a horizontal line​
Ierofanga [76]

Step-by-step explanation:

horizontal lines will have a gradient(m) of 0

so if m=0 , the line is horizontal

formula to find m:

m=y2-y1 / x2-x1

insert coordinates into formula

m =  \frac{ - 2 - ( - 2)}{ - 4 - 3}  \\  \\ m =  \frac{ - 2 + 2}{ - 7}  \\ m =  \frac{0}{ - 7}  \\ m = 0

As m=0 , therefore it is a horizonta line.

hope this helps..

The sum of three numbers is 85. The second is 7 more than the first. The third is 2 more than four times the second. Find the nu
9966 [12]
Let x=the first number
Then x+7=second number
And 4(x+7)+2=third number (2 more than 4 times the second)
Now we are told that:
x+(x+7)+(4(x+7)+2)=85 get rid of parentheses
x+x+7+4x+28+2=85 simplify
6x+37=85 subtract 37 from each side
6x+37-37=85-37
6x=48
x=8---first number
x+7=8+7=15 second number
4(x+7)+2=4*15+2=62 third number

8+15+62=85
85=85

- sqrt737 is rational or irrational
denpristay [2]

Answer: <u>Irrational </u>

It's irrational because of how 37 comes out of the square root.

For example:

The square root of 64 comes out to 8, which is a whole number. But 37, comes out as an integer and a decimal.
