What would make it true for just one value of x?

Answer:

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.

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:

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]

(B) No

Step-by-step explanation:

If I remember correctly a solution is a point that is on the shaded area or on a solid line, the point 3,-3 is not on the shaded region and not on a solid line. Even if it was on the line in this problem it wouldn't be a solution because it is a dotted line. Hope this helps!

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:

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]

[tex]⇢3x = 84[/tex]

[tex]⇢x = \frac{84}{3} [/tex]

Step-by-step explanation:

[tex]5 {x}^{2} - 4 {y}^{2} + 80 = 0[/tex]

[tex]5 {x}^{2} - 4 {y}^{2} = - 80[/tex]

[tex] - \frac{ 5{x}^{2} }{16} + \frac{ {y}^{2} }{20} = 1[/tex]

[tex] \frac{ {y}^{2} }{20} - \frac{5 {x}^{2} }{16} = 1[/tex]

To find foci,

[tex]c = \sqrt{ {a}^{2} + b {}^{2} } [/tex]

so

[tex]c = \sqrt{20 + 16} [/tex]

[tex]c = \sqrt{36} [/tex]

[tex]c = ±6[/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

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:

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

Answer:

It makes a right traiangle.

Step-by-step explanation:

Graph the points and you will see that it makes a right triangle.

The figure formed by the vertices A(3,5), B(3,1), and C(0,1) is a right-angled triangle.

In this triangle, side BC is the shortest side with a length of 3 units, side AB is the longest side with a length of 4 units, and side AC has a length of 5 units.

The right angle is formed between side BC and side AC at point C (0,1).

Here, we have to identify the figure with the given vertices A (3,5), B (3,1), and C (0,1), we can plot these points on a coordinate plane.

Let's plot the points A(3,5), B(3,1), and C(0,1) on a Cartesian coordinate plane.

A(3,5): This point is located at x-coordinate 3 and y-coordinate 5.

B(3,1): This point is located at x-coordinate 3 and y-coordinate 1.

C(0,1): This point is located at x-coordinate 0 and y-coordinate 1.

Since point A and point B share the same x-coordinate (x = 3), they lie on a vertical line. Point C has a different x-coordinate, so we need to connect it with the others to complete the figure.

The figure formed by connecting the points A, B, and C is a right-angled triangle.

To calculate the distances between the vertices, we'll use the distance formula:

Distance between two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is given by:

Distance = √[tex]((x_2 - x_1)^2 + (y_2 - y_1)^2)[/tex]

Let's calculate the distances:

Distance between A(3,5) and B(3,1):

Distance_AB = √[tex]((3 - 3)^2 + (1 - 5)^2)[/tex]

Distance_AB = √(0 + 16)

Distance_AB = √16

Distance_AB = 4 units

Distance between A(3,5) and C(0,1):

Distance_AC = √[tex]((0 - 3)^2 + (1 - 5)^2)[/tex]

Distance_AC = √[tex]((-3)^2 + (-4)^2)[/tex]

Distance_AC = √(9 + 16)

Distance_AC = √25

Distance_AC = 5 units

Distance between B(3,1) and C(0,1):

Distance_BC = √[tex]((0 - 3)^2 + (1 - 1)^2)[/tex]

Distance_BC = √[tex]((-3)^2 + 0^2)[/tex]

Distance_BC = √9

Distance_BC = 3 units

As we calculated, the distances between the vertices of the figure are:

AB = 4 units

AC = 5 units

BC = 3 units

Based on the distances, we can determine that the figure formed by the vertices A(3,5), B(3,1), and C(0,1) is a right-angled triangle.

In this triangle, side BC is the shortest side with a length of 3 units, side AB is the longest side with a length of 4 units, and side AC has a length of 5 units.

The right angle is formed between side BC and side AC at point C (0,1).
