Answer:

x=15

Step-by-step explanation:

A line is 180 degrees

We know that 8x+19=139

8x+19=139

subtract 19 from both sides to isolate x

8x=120

divide both sides by 8

8x/8=120/8

x=15

Answer:

x = 23 y =67

Step-by-step explanation:

Since a rectangle is made up of 4 right angles you can solve y with the following equation:[tex]23 + y =90[/tex]

Then to solve for x, since x, y and the right angle makes up a triangle and a triangle has 180 degrees. You can use the following equation to solve for x:

[tex]x + 67 + 90 = 180[/tex]

Answer:

Expression equivalent to (k + k)(4) is 28.

Step-by-step explanation:

Given:

k(x) = 5x - 6

We need to find an expression equivalent to (k + k)(4)

First, we find,

(k + k)(x) = k(x) + k(x)

            = ( 5x - 6 ) + ( 5x - 6 )

            = 5x - 6 + 5x - 6

            = 5x + 5x - 6 - 6

            = 10x - 12

Now, (k + k)(4) = 10(4) - 12 = 40 - 12 = 28

Therefore, the Expression equivalent to (k + k)(4) is 28.

Considering the vertex, the quadratic equation that models the path of the golf ball is given by:

y = -0.0011875(x - 400)² + 190

The equation of a quadratic function, of vertex (h,k), is given by:

y = a(x - h)² + k

In which a is the leading coefficient.

In this problem, the vertex is at the maximum height of the parabola, given by (400, 190), hence h = 400, k = 190, and:

y = a(x - 400)² + 190

It starts at the origin, that is, when x = 0, y = 0, hence:

0 = 400²a + 190

a = -190/400²

a = -0.0011875.

Hence, the equation is:

y = -0.0011875(x - 400)² + 190

Answer: 0.9

Step-by-step explanation: All you need to just keep your decimal (0.9) as it is since 4 and 2 are below 5 then you don't need to round it higher. I hope this helped!

0.942

the nearest tenth of 0.942

to round to the nearest tenth, if the number in hundredths place is 5 or more you'll have to round up, if not keep it as it is and remove all the digits in the right side.

=0.9

hence, the nearest tenth of 0.942 is 0.9

Answer:

[tex]2x^{6}y^{2} }[/tex]

Step-by-step explanation:

Just Simplifying the Fraction.

we get,

[tex]=\frac{12x^{9} y^{4} }{6x^{3}y^{2} } \\\\=2x^{9-3} y^{4-2} \\=2x^{6} y^{2}[/tex]

Answer:

18.36 to nearest hundredth.

Step-by-step explanation:

base of the triangle = 1/3 * 32 = 16.

x^2 = 9^2 + 16^2

x^2 = 81 + 256 =  337

x = √337 = 18.36.

Answer:

1. Given the slope is 2, the equation now looks like y = 2x +b Given P (−1,4) we can solve for the b variable by substituting the x and y cordinates. 4 = 2 ⋅ (− 1) + b 4 = − 2 + b b = 6 Therefore the equation that has the slope of 2 and passes through the point (− 1,4) is y = 2x + 9 so it is d

2. i you can do that.

3. The equation for the slope of a line and the points also called point slope form of equation of a straight line is given by: y − y1 = m (x − x1) Whereas the slope-intercept form the equation of the line is given by: y = mx + b. Where b is the y-intercept.

4.In the formula,y = the y-coordinate of any point on the line,m = slope,x = the x-coordinate of any point on the line,and b = ...

Plug the slope and y-intercept into the formula. Remember,the slope is equal to the rise over the run.

Answer:

x = 28

Step-by-step explanation:

Supplementary angles mean that both angles are equal to 180. So, the equation becomes 3x + 96 = 180. Solving for x, we get 28.

Answer:

The value of x is 28

Step-by-step explanation:

Given :

Now,

Supplementary angles are a pair of angles that make sum of 180° .

Therefore, The sum of given angles will be equal to 180°.

i.e. one angle + other angle = 180°

Substituting the values of angles , we get..

[tex]⇢3x + 96 = 180[/tex]

[tex]⇢3x = 180 - 96[/tex]

Answer:

  (b)  y = -7x -27

Step-by-step explanation:

When x and y in the equation y = f(x) are replaced by (x-h) and (y-k), the function graph is translated h units right and k units up. The translated function can be written as ...

  y -k = f(x -h)

  y = f(x -h) +k . . . . . . add k

__

Your function is ...

  y = -7x

and you want to translate it by (h, k) = (-5, 8). That makes it ...

  y' = -7(x -(-5)) +8 = -7x -35 +8

  y' = -7x -27
