Step-by-step explanation:

Domain of a function represents the set of x-values (input values) and y-values (output values) of the function represent the Range of the function.

Given function is,

If Domain (input values) of this function is,

{-12, -6, 3, 15}

Table for the input-output values of this function,

x        -6         3        15       -12

y        11         5         -3        15

Answer:

2 mm

Step-by-step explanation:

Let x be the sides of the original square,

then the area of the original square is x^2

The sides of the new square is x + 6

The area is (x + 6)^2

Then (x + 6)^2 = 16*x^2

Take square root on both sides and get

x + 6 = 4x,

3x = 6

so x = 2 mm

Answer:

Step 1

Step-by-step explanation:

they were supposed to multiply 2x by 4 and -1 by 4 but they only multiplied 2x by 4.

Answer:

B. Incorrect with error in STEP 1

Step-by-step explanation:

3x - x + 4 = 4(2x - 1)

Step 1: Simplify

2x + 4 = 8x - 4

Step 2: Subtract 8x from both sides.

2x+4−8x=8x−4−8x

−6x+4=−4

Step 3: Subtract 4 from both sides.

−6x+4−4=−4−4

−6x=−8

Step 4: Divide both sides by -6.

-6x/-6 = -8/-6

x = 4/3

so, the other answer is wrong because she did not multiply the numbers in the parenthesis correctly

Answer:

104 m²

Step-by-step explanation:

From inspection of the diagram, we can see that the composite figure is made up of a triangle and a rectangle.

Triangle

If you turn the figure 90° clockwise, you will see that the base of the triangle = 8m and the height of the triangle = 6m.

Area of a triangle = 1/2 x base x height

⇒ area of the triangle = 1/2 x 8 x 6 = 24 m²

Rectangle

From inspection, the length of the rectangle = 10m and the width = 8m

Area of a rectangle = length x width

⇒ area of the rectangle = 10 x 8 = 80 m²

Composite figure area

Therefore the total area of the figure = area of triangle + area of rectangle

⇒ total area = 24 + 80 = 104 m²

Answer:

104 m^2

Answer:it’s 10x + 12

Step-by-step explanation:

your welcome

The sum of ten times a number and 12 can be written as 10x + 12.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The expression "ten times a number" can be represented as 10x, where x is the number.

So, "the sum of ten times a number and 12" can be written as:

10x + 12

This expression represents a mathematical operation where 10 times the number is added to 12.

Thus,

The sum of ten times a number and 12 can be written as 10x + 12.

Rhombus has all sides equal. The total amount of paper that will be needed to cover the wall is 396 in².

Given to us

Each rhombus will be 6 inches tall and 4 inches wide.

A.)

The area of each rhombus can be found using the formula,

[tex]Area = \dfrac{1}{2} \times d_1 \times d_2[/tex]

We know that diagonals of the rhombus are of length 6 in and 4 in. therefore,

[tex]Area = \dfrac{1}{2} \times 6 \times 4\\\\Area = 12\ in^2[/tex]

Hence, the area of the single rhombus is 12 in².

We know that the wall is 11 feet long, also, 1 foot = 12 inches, therefore,

11 feet = 132 in.

Now, since the wall is 132 in long and the width of the rhombus is 4 in, therefore, the number of rhombi that will be needed,

[tex]\dfrac{132}{4} =33[/tex]

Hence, the number of rhombi that will be needed is 33.

We know the area of each paper rhombus, also, we know the number of rhombi that will be needed. Therefore,

[tex]33 \times 12 = 396\ in^2[/tex]

Hence, the total amount of paper that will be needed to cover the wall is 396 in².

Answer:

x = 24

PS = 45

Step-by-step explanation:

Perimeter of P Q R S is :

( 4x + 1 ) + ( 2x - 3 ) + ( 2x - 3 ) + 4 + ( 4x + 1 )

4x + 1 +  2x - 3  +  2x - 3 + 4 +  4x + 1

And in the question , given that the perimeter of this figure is 288.

Now let us find the value of x.

4x + 1 +  2x - 3  +  2x - 3 + 4 +  4x + 1  = 288

4x + 2x + 2x + 4x + 1 - 3 - 3 + 4  + 1 = 288

12x + 0 = 288

12x = 288

Divide both sides by 12

x =  24

And now let us find the value of PS

PS = 2x - 3

PS = 2× 24 - 3

PS = 48 - 3

PS = 45

Answer:

The answer is A. 12%

Step-by-step explanation:

Answer:

(exact form)   z= -7/5

or

(decimal form)   z= -1.4

or

(mixed number form)   z= -12/5

Step-by-step explanation:

Answer:

The value of z is -7/5

Step-by-step explanation:

1/3 (z + 1/5) = -2/5

z/3 + 1/5 × 3 = -2/5

z/3 + 1/15 = -2/5

15z + 3/45 = -2/5

15z + 3 = -2(45) ÷ 5

15z + 3 = -2(9)

15z + 3 = -18

15z = -18 – 3

15z = -21

z = -21/15

z = -7/5

Thus, The value of z is -7/5

Answer:

y=1/5x-4

Step-by-step explanation:

Hi there!

We want to write the equation of the line, and we're given that the line has a slope of 1/5, and the y intercept of the line is (0, -4)

There are multiple ways to write the equation of the line, the most popular being slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

We are already given the slope (1/5), so we can plug it in as m in the equation.

y=1/5x+b

Now for b, we are also given the y intercept; the value of b is the value of y at the point of the y intercept

In this case, b would equal -4

So substitute -4 as b into the equation:

y=1/5x-4

This is the equation of the line.

Answer:

c) x = 1 ± i √29 / 5​

Step-by-step explanation:

assuming we are solving for x we can use the quadratic formula

quadratic formula : [tex]\frac{-b+or-\sqrt{b^2-4(a)(c)} }{2(a)}[/tex]

where the values of a,b and c are derived from the equation

the equation is put in quadratic form : ax² + bx + c

so in 5x² -2x + 6 a = 5 , b = - 2 and c = 6

we then plug these values of a, b and c into the quadratic formula

recall quadratic formula [tex]\frac{-b+or-\sqrt{b^2-4(a)(c)} }{2(a)}[/tex]

a = 5 , b = - 2 , c = 6

[tex]\frac{-(-2)+or-\sqrt{(-2)^2-4(5)(6)} }{2(5)}[/tex]

remove parenthesis at -(-2) to get positive 2 because the negative signs cancel out

[tex]\frac{2+or-\sqrt{(-2)^2-4(5)(6)} }{2(5)}[/tex]

evaluate exponent

[tex]\frac{2+or-\sqrt{4-4(5)(6)} }{2(5)}[/tex]

multiply -4(5)(6)

[tex]\frac{2+or-\sqrt{4-120} }{2(5)}[/tex]

subtract 120 from 4

[tex]\frac{2+or-\sqrt{-116} }{2(5)}[/tex]

multiply 2 and 5

[tex]\frac{2+or-\sqrt{-116} }{10}[/tex]

because we cant have a negative square root we replace the negative sign with i (which equals -1 )  and add it to the outside of the square root

[tex]\frac{2+or-i\sqrt{116} }{10}[/tex]

we then simplify  the radical

[tex]\frac{2+or-2i\sqrt{29} }{10}[/tex]

we then simplify the fraction

2/10 = 1/5 so both 2's cancel out

[tex]\frac{1+or-i\sqrt{29} }{10}[/tex]

the answer is C

Answer:

Yes.

Step-by-step explanation:

Replace x with -2 and y with -3.
