Answer:

Step-by-step explanation:

(3 - 7) - 9 - 5 = -4 - 9 - 5

                   = -18

3 - (7 - 9) - 5 = 3 - (-2) - 5

                    = 3 + 2 - 5

                    = 5 - 5

                    = 0

3 - 7 - (9 - 5) = 3 - 7 - 4

                    =  3 - 11

                    = -8

Answer:

width = 18.97 inches

Step-by-step explanation:

To find the smallest width of the box to fit the bat, we need to put the bat in the diagonal of the box.

The diagonal of the box is given by:

diagonal^2 = length^2 + width^2 + height^2

Then, using the diagonal = 36 inches, length = 30 inches and height = 6 inches, we have:

36^2 = 30^2 + width^2 + 6^2

1296 = 900 + width^2 + 36

width^2 = 360

width = 18.97 inches

Step-by-step explanation:

the equation for the line is written in slope intercept form y=mx+b m is the slope and b is the y intercept where the line crosses the y-axis

Hello! :)

This equatio is written in slope-intercept form, which looks like so:

y=mx+b

Here, m is the slope, and b is the y-intercept.

In the given equation, 2 is the slope, and 3 is the y-intercept.

I HOPE IS RIGHT

Hey!!!

here's your answer

X+128=180( sum of angle in straight line)

or,X=180-128

X=52 degree.

So the value of X is 52 degree.

Hope it helps...

Step-by-step explanation:

Answer:

3x + 3

Step-by-step explanation:

Answer:

(- 6, 0 )

Step-by-step explanation:

Given the 2 equations

3x + 2y = - 18 → (1)

2x + 9y = - 12 → (2)

Multiplying (1) by 2 and (2) by - 3 and adding will eliminate the term in x, that is

6x + 4y = - 36 → (3)

- 6x - 27y = 36 → (4)

Add (3) and (4) term by term to eliminate x

- 23y = 0

y = 0

Substitute y = 0 into either of the 2 equations and evaluate for x

Substituting into (1)

3x + 0 = - 18

3x = - 18 ( divide both sides by 3 )

x = - 6

Solution is (- 6, 0 )

Answer: y =2x

Step-by-step explanation:

Hi, to answer this question we have to write an equation with the information given:

Since a circle with a 2-inch radius has a diameter of 4 inches, it means that the diameter of a circle (y) is equal to two times its radius (x).

Mathematically speaking:

y = 2 x

Answer:

x=1

Step-by-step explanation:

-4-2(3-x)=-2(x+3)

Expand parentheses:

-4-6+2x=-2x-6

Add 2x+6 to both sides:

4x-4=0

Add 4 to both sides:

4x=4

Divide both sides by 4:

x=1

i) Focus ( 0,a) = [tex](0,\frac{1}{2} )[/tex]

ii) The equation of the directrix is

                            [tex]y = -\frac{1}{2} or y +\frac{1}{2} =0[/tex]

Step-by-step explanation:

Step(i):-

  A parabola is the set of all points in a plane that are equidistant from a fixed line and a fixed point (not in a line) in the plane

• The Fixed line is called the directrix of the parabola.

• The Fixed point is called the focus of the parabola.

• A line through the focus and perpendicular to the directrix is called the axis of the parabola.

• The point of intersection of parabola with the axis is called the vertex of the parabola.

Given Parabola x² = 2 y

Comparing  x² = 4 a y

                   4 a = 2

                     [tex]a = \frac{1}{2}[/tex]

  Focus ( 0,a) = [tex](0,\frac{1}{2} )[/tex]

Step(ii)

The equation of the directrix is y = -a or y +a=0

The equation of the directrix is

                            [tex]y = -\frac{1}{2} or y +\frac{1}{2} =0[/tex]

The equation of the directrix is 2 y +1 =0

  D)  g(x) = |x +6| -2

Step-by-step explanation:

To translate f(x) h units to the right and k units up, you use the transformation ...

  g(x) = f(x -h) +k

You want to translate your function 6 units left and 2 units down, so (h, k) = (-6, -2) and the transformed function is ...

  g(x) = |x +6| -2

Answer:

A mathematical term that does not include an equal or inequality sign is called an expression.

Step-by-step explanation:

Example:

(2+2)4+8

You do what's in parenthesis first, which is 2+2 = 4

Then, you multiply 4 by 4 because there is no sign between the paratinsees

4 x 4= 16

Then you add 8.

Your answer is 24.
