Answer:

Domain: [tex][-1,\infty)[/tex]

Range: [tex](-\infty, 3][/tex]

Decreases over: [tex](-1,-\infty)[/tex]

Step-by-step explanation:

Given

[tex]f(x) = -\sqrt{x + 1} + 3[/tex] --- Missing from the question

Solving (a): The domain

To get the domain, the expression under the square root must not be negative.

In other words:

[tex]x + 1 \ge 0[/tex]

Solve for x

[tex]x + 1 -1\ge 0-1[/tex]

[tex]x \ge -1[/tex]

Hence, the domain is:

[tex][-1,\infty)[/tex]

To get the range, we plot the values of the domain in the expression.

[tex]x = -1[/tex]

[tex]f(x) = -\sqrt{x + 1} + 3[/tex]

[tex]f(-1) = -\sqrt{-1+1} +3[/tex]

[tex]f(-1) = -\sqrt{0} +3[/tex]

[tex]f(-1) = -0 +3[/tex]

[tex]f(-1) = 3[/tex]

[tex]x = \infty[/tex]

[tex]f(\infty) = -\sqrt{\infty +1}+3[/tex]

[tex]f(\infty) = -\sqrt{\infty}+3[/tex]

[tex]f(\infty) = -\infty+3[/tex]

[tex]f(\infty) = -\infty[/tex]

So, the range is: [tex](-\infty, 3][/tex]

To get the interval where the function increases or not, we simply plot the graph of f(x).

See attachment for graph.

From the attachment, it will be observed that the graph of f(x) continuously decreases from x = -1, and it never increased.

This implies that, the graph decreases over the interval [tex](-1,-\infty)[/tex]

Answer:

Replace all occurrences of y with 6x−3 in each equation.

Replace all occurrences of y in 18x−3y=9 with 6x−3 .

18x−3(6x−3)=9

y=6x−3

Simplify 18x−3(6x−3).

9=9

y=6x−3

Remove any equations from the system that are always true.

y=6x−3

Step-by-step explanation:

Answer: y = 80*

all circles have 360* so we can subtract what we have to get what we want

Answer:

$150

Step-by-step explanation:

Costo de 2 cajas de pastillas = $ 320

Costo de la solicitud y tarifa de revisión = x

La ecuación se da como:

320 + x = 470

x = 470 - 320

x = 150

El costo de la solicitud y la tarifa de revisión = $ 150

Answer:

y=9x

Step-by-step explanation:

First let's find the slope of this.

To find the slop we can take two points.

(1,9) & (3,27)

27-9/ 3-1 (slope equation) = 18/2=9

The slope of the equation is 9.

Now let's use point-slope form to find the equation.

(1,9)

y-9=m(x-1) (substitute the x2 and y2 values for the coordinate values)

y-9=9(x-1) (substitute m for the slope)

y=9x-9+9

y=9x

Answer:

43

Step-by-step explanation:

180 - (109+28) = 43

the sum of all angles in a triangle is 180

Answer:

C = 101

E = 46

Step-by-step explanation:

79 + 134 = 213

180 - 79 = 101 (C+F has to equal 180)

79 + 134 + 101 = 314

360 - 314 = 49 (trapezoids have a total degree of 360)

The measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.

It is given in the picture that measures the angles of a trapezoid.

It is required to find the other angles.

It is defined as the quadrilateral having four sides in which two sides are parallel to each other it is a 2-dimensional geometry.

We have a trapezoid CDEF in which ∠D = 134° and ∠CFE = 79°

We know in trapezoid:

∠C+∠F = 180° and

∠D+∠E = 180°

For ∠C = 180° - ∠F ⇒ 180° - 79° ⇒ 101°

For ∠E = 180° - ∠E  ⇒ 180° - 134° ⇒46°

We have another trapezoid JKLM in which ∠K = 83°

We know in isosceles trpezoid:

∠K = ∠J = 83° and

∠L = ∠M

∠L = 180° - ∠K ⇒ 180° - 83°  ⇒ 97° ⇒ ∠M

Thus, the measure of angles are ∠C = 101°, ∠E = 46°, ∠J = 83°, ∠L =97°, and ∠M = 97°.

Answer:

5m

Step-by-step explanation:

add them and add 1

An expression equivalent to m + m + m + m as a sum of two terms is 4m.

An expression is combination of variables, numbers and operators.

The given expression is:

m + m + m + m

Equivalent expressions are expressions that work the same even though they look different.

We can combine like terms to simplify the expression:

m + m = 2m

Now plug in the expression of m+m in the given expression.

So the expression becomes:

m + m + m + m = 2m + 2m

Now we have expressed the given expression as a sum of two terms, which are both 2m:

2m + 2m = 4m

Therefore, an expression equivalent to m + m + m + m as a sum of two terms is 4m.

Answer:

  -2/3

Step-by-step explanation:

The slope formula is useful for this.

  m = (y2 -y1)/(x2 -x1)

  m = (2 -(-6))/(-9 -3) = 8/-12

  m = -2/3

The slope of the line is -2/3.

Equation = 4(2x - 5) + 15 =1

First:

4(2x - 5) +15 - 15 = 1 - 15

4(2x-5) = - 14

Then

4(2x-5)/4 = -14/4

2x - 5 = -7/2

+5               +5

2x = -7/2 + 5

Simplify

2x = -7/2 + 5

2x = 3/2

Divide

2x = 3/2

2x/2 = (3/2)/2

Answer:

56πx² + 36πx + 6π square inches

Step-by-step explanation:

The radius of a cylindrical gift box is ​(3x+1​) inches. The height of the gift box is twice the radius. What is the surface area of the​ cylinder? Write your answer as a polynomial in standard form.

The surface area of a cylinder is given as:

2πr(r + h)

The radius of a cylindrical gift box is ​(3x+1​) inches.

The height of the gift box is twice the radius = 2(3x + 1) inches

= 6x + 2 inches

The surface area of the cylinder is:

= 2 × π × 3x + 1( 3x + 1 + 6x + 2) square inches

= 2 × π × 3x + 1(9x + 3) square inches

= 2π × 3x + 1(9x + 3) square inches

= 6πx + 2π( 9x + 3) square inches

= 6πx (9x + 3) + 2π( 9x + 3) square inches

= 56πx² + 18πx + 18πx + 6π square inches

= 56πx² + 36πx + 6π square inches

The surface area of the​ cylinder is 56πx² + 36πx + 6π square inches
