if 3x/4 - 13 = -9 then what is the value of x^2


show work!

Answer:

-3/4

Step-by-step explanation:

First, pick two coordinates.

(0,2) and (4,-1)

Then do the rise over run or y/x.

The y is 3 and the x is 4. That is 3/4.

Since the line is going down, it will be negative.

The answer is -3/4.

Answer:

65

Step-by-step explanation:

The triangle is isosceles. That means that the Vertical line meets the base at right angles because the peak angle is bisected. we are to assume. So the left angle is given as 25 degrees. The base and vertical angle meet and 90 degrees and so we solve for x, because every triangle has 180 degrees.

x + 25 + 90 = 180                  Combine the left.

x + 115 = 180                          Subtract 115 from both sides

x = 180 - 115

x = 65

According to given figure, the two sides of the triangle are equal. therefore it's opposite angles will be equal as well !

that is ~

Both angles measure 25° and the central (non - equal) Angle among them is 2x (2 times the Angle x)

Now, let's use Angle sum property of Triangle to find the value of x ~

Answer:

sin (32) = 8.5/x

Step-by-step explanation:

hypotenuse is opposite the right angle (x)

Looking at the 32° angle , the number 8.5 is the opposite 32° angle

Trig ratios are    sin ∠ =  opposite/hypotenuse

                           cos ∠ = adjacent/ hypotenuse

                           Tan ∠ = opposite/ adjacent

Explanation:

I got this same question and got it right.

Using the mean formular, the sum of the four scores that are not the median would be 360.

Average or mean score = 450 / 5

Mean score = 90

Hence, median score = mean score = 90

The sum of the 4 scores that are not the median can be calculated thus :

Sum of the 4 scores = 450 - 90 = 360

Hence, the sum of the 4 scores that are not the median is 360.

Step-by-step explanation:

x - 12 < 15

Answer:

x=1, y=3

Step-by-step explanation:

Rearrange equations 1 and 2 so that y is the subject

3x^2 = xy

Equation 1) y = 3x

Equation 2) 2y = 5x + 1

multiply the first equation by 2

2y = 6x

2y = 5x + 1

subtract the 2 equations from each other

2y - 2y = 6x - (5y +1)

0 = x - 1

x = 1

substitute x = 1 in the second equation

2y - 5(1) = 1

2y = 1 + 5

2y = 6

y = 3

Answer:

The right side of the equation is only a different way of writing the left side, so any value of x will solve this equation.

The equation   − 2 (  x  +  3  )  =  − 2 x  −  6  does not have any specific solutions for the simple reason that the left and rigth sides are two representations of the same equation.

We have  − 2 (  x  +  3  )  means that each term inside the parenthesis should be multiplied with  − 2 , i.e.

− 2 (  x  +  3 )  =  − 2  ⋅  x  −  2  ⋅  (  +  3 )  =  − 2 x  −  6

Which is exactly what the right side says.

Any value of x will, therefore, fulfill this equation.

Answer:

10*pi+20

Step-by-step explanation:

The diameter is 20m. The perimeter can be split into the curve part and the diameter. The curve part is 1/2 the length of the circumference of the circle, which is 1/2 of 20*pi, which is 10*pi. So the perimeter is 10*pi+20

Answer:

x = –9.41 or x = –6.59

Step-by-step explanation:

Hope it's help, study well goodluck

By solving the given Equation (x+8)² - 2 = 0 we get the Value from lesser x =  -9.41 and greater x = -6.59

To solve the Equation (x+8)² - 2 = 0 and find the values of x,

Step 1: Expand the equation

(x+8)² - 2 = 0

(x+8)(x+8) - 2 = 0

(x² + 16x + 64) - 2 = 0

x² + 16x + 62 = 0

Step 2: Set the equation equal to zero and rearrange

x² + 16x + 62 = 0

Step 3: Use the quadratic formula

The quadratic formula states that for an equation in the form ax² + bx + c = 0, the solutions for x can be found using the formula:

x = (-b ± √(b² - 4ac)) / (2a)

In our equation, a = 1, b = 16, and c = 62.

Substituting these values into the quadratic formula, we get:

x = (-16 ± √(16² - 4(1)(62))) / (2(1))

x = (-16 ± √(256 - 248)) / 2

x = (-16 ± √8) / 2

Step 4: Simplify the square root

√8 can be simplified as follows:

√8 = √(4 × 2)

     = √4 × √2

     = 2√2

Substituting this into our equation:

x = (-16 ± 2√2) / 2

Step 5: Simplify further

We can simplify the expression by dividing both the numerator and denominator by 2:

x = -8 ± √2

So the solutions for x are -8 + √2 and -8 - √2.

Rounding to two decimal places, the solutions are approximately:

lesser x = -8 - √2 ≈ -9.41

greater x = -8 + √2 ≈ -6.59

Therefore, the solutions for x, from least to greatest (rounded to two decimal places), are -9.41 and -6.59.
