Answer:

A

Step-by-step explanation:

Answer:

[tex]y=-0.667x+-10[/tex]

Step-by-step explanation:

Given the following question:

Point A = (-9, -4), (x1, y1)
Point B = (-6, -6), (x2, y2)

[tex]m=\frac{y2-y1}{x2-x1}[/tex]
[tex]m=\frac{-6--4}{-6--9} =\frac{-2}{3}[/tex]
[tex]m=\frac{-2}{3}[/tex]

Write in slope intercept form:

[tex]y=mx+b[/tex]
[tex]m=\frac{-2}{3}=-2\div3=-0.667[/tex]
[tex]y=-4[/tex]
[tex]x=-9[/tex]
[tex]-4=-0.667\times-9+b[/tex]
[tex]-0.667\times-9=6[/tex]
[tex]b=-10[/tex]
[tex]y=-0.667x+-10[/tex]

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:

Yes, they're the same.

Step-by-step explanation:

-3-2c can be re-written as -1(2c+3) and -3 can be re-written as -1(3). So you can rewrite the fraction as -1(2c+3)/-1(3). The -1's go away and the new fraction is (2c+3)/3.

anyways, hope this helped! :)

Answer:

[tex]4x^2y-7xy+10xy^2[/tex]

Step-by-step explanation:

We have [tex]\left(6x^2y-8xy+7xy^2\right)+\left(3xy^2-2x^2y+xy\right)[/tex] and need to add them together.

Though complicated at first, we can simplify by taking out the parenthesis and making this whole question into one equation.

[tex]\left6x^2y-8xy+7xy^2\right+\left3xy^2-2x^2y+xy\right[/tex]

Now combine like terms, meaning you can only add the terms that have the same ending, in math, you cannot add numbers that have different exponents or variables.

Therefore:

[tex]\left6x^2y-8xy+7xy^2\right+\left3xy^2-2x^2y+xy\right[/tex]

[tex]6x^2y-2x^2y-8xy+xy+7xy^2+3xy^2[/tex]

[tex]4x^2y-7xy+10xy^2[/tex]

Answer:

y = 55°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

100° is an exterior angle of the triangle , then

y + 45° = 100° ( subtract 45° from both sides )

y = 55°

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:

r = 3.95 mm (nearest hundredth)

Step-by-step explanation:

[tex]\textsf{volume of a cylinder} = \pi r^2h[/tex]

(where r = radius and h = height)

Given, volume = 686 mm² and height = 14 mm:

[tex]686=\pi r^2\times14[/tex]

[tex]\implies\pi r^2=686 \div14=49[/tex]

[tex]\implies r^2=49 \div \pi[/tex]

[tex]\implies r=\sqrt{49 \div \pi }=3.949327085...[/tex]

[tex]\implies r=3.95 \ \textsf{mm}[/tex]

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:

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:

slope: 2 as we see, with every increase in x, y increase twice the more.

Step-by-step explanation:

The slope of the linear graph in the question obtained using the ratio of the rise and run of the line is 2.

Recall :

Slope = Rise / Run

From the graph :

Rise = y2 - y1 = 5 - (-1) = 5 + 1 = 6

Run = x2 - x1 = 2 - (-1) = 2 + 1 = 3

The slope of the graph can be expressed thus :

Slope = Rise / Run = 6 /3 = 2

Therefore, the slope of the line in the graph attached is 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.
