Answer:

6a + 6b

Step-by-step explanation:

Use  Distributive property: a( b +c) =(a *b) +(a*c)

6(a + b) = 6*a + 6*b

            = 6a+ 6b

Step-by-step explanation:

it means the shape of the balloon is close to a sphere.

the volume of a sphere is

4×pi×r³

so, it bases on r³.

that means any scaling factor f between 2 similar balloons for the radius has to be multiplied in 3 times (once for every "r").

in our case we know

8.4 = 2.8 × f

f = 8.4 / 2.8 = 3

so,

large volume = small volume × f×f×f =

= small volume × f³ = 92×3³ = 92×27 =

= 2,484 cm³

Answer:

b) 70.6

Step-by-step explanation:

To calculate average you need to add up all the numbers and divide by the quantity of numbers. They are calculating with mph, with ten hours, so there will be ten numbers. First you do 73 x 6 (6 because of 6 hours of 73 mph) which is 438. Then you do 67 x 4 which is 268. you add it up, then find a total of 706. Then you divide it by ten to find the answer 70.6

Using the concept of closure, it is found that the false statement is given by:

Polynomials are closed under division. When you divide polynomials, the result will always be a polynomial.

A polynomial is said to be closed under an operation if the operation always results in a polynomial. It holds true for the addition, subtraction and  multiplication operations.

As for the division, if the degree of the numerator is lower than the degree of the denominator, the result of the division will have a negative exponent, which is not a polynomial, hence the division operation is not closed.

Answer:

[tex] \: [/tex]

Step-by-step explanation:

It is given that, The circumference of a circle is 198 cm and we are to find the radius of the circle.

[tex] \: [/tex]

To find the radius of the circle we must know this formula first :

[tex]\\{ \longrightarrow \qquad{ \underline {\boxed{ \pmb{ \mathfrak{ \: 2 \pi r \: =Circumference_{(circle)}}}}}}} \: \: \bigstar \\ \\ [/tex]

Now substituting the values in the formula :

[tex]\\{ \longrightarrow \qquad{ {{ \tt{ \: 2 \times 3.14 \times r \: =198}}}}} \\ \\ [/tex]

[tex]{ \longrightarrow \qquad{ {{ \tt{ \: 6.28 \times r \: =198}}}}} \\ \\ [/tex]

[tex]{ \longrightarrow \qquad{ {{ \tt{ r \: = \frac{198}{6.28} }}}}} \\ \\ [/tex]

[tex]{ \longrightarrow \qquad{ \pmb {{ \frak{ r \: = 31.528 }}}}} \\ \\ [/tex]

Therefore,

-4x-6=-5y+9y

-4x-6= 4y

-4x= 4y+6

4x=-4y-6

x= (-4y-6)/4

Answer:

i believe it's (1,-8)

Step-by-step explanation:

you subtract the "+3," since it's really the opposite, from 4 to get 1. The -8 stays the same since the transformation doesn't affect the y's.

Since  the resulting function has a leading degree of 1, hence the set or ordered pairs (1,6), (2,9), (3,12), (4,15) satisfies a linear function

The standard equation of a linear function is y = mx + b

where:

m is the slopee

b is the y-intercept

Using the coordinate point (1, 6) and (2, 9)

Find the slope

Slope = 9-6/2-1
Slope = 3/1

Slope = 3

For the y-intercept

Recall that y = mx + b

9 = 3(2) + b

b = 3

Determine the equation

y = 3x + 3

Since the resulting function has a leading degree of 1, hence the set or ordered pairs (1,6), (2,9), (3,12), (4,15) satisfies a linear function.

The slope of a line perpendicular to the line whose equation is 2x + 3y = 24 is,

⇒ m = - 2/3

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The perpendicular line is,

⇒ 2x + 3y = 24

Now,

Since, Product of slopes of perpendicular line are - 1.

So, We need to find the slope of the line.

Hence, Slope of the line is,

2x + 3y = 24

y = - 2/3x + 8

m = dy/dx = - 2/3

m = - 2/3

Thus, The slope of a line perpendicular to the line whose equation is 2x + 3y = 24 is,

⇒ m = - 2/3

Step-by-step explanation:

Number : 2 Cost : $10

Number : 3 Cost : $15

Number : 7 Cost : $28

⇒ The cost is not always the same per person.

⇒ Predicted number in a group for cost of $40 :

⇒ Since 7 costs $28 and if we use 8, it will be $5 per head but the price difference will be too large

⇒ 10 people is more reasonable at a rate of $4 per person

The coordinates of the final vertices of the two transformations are W" = (-4,1), X" = (-2,1), Y" = (-2,4) and Z" = (-3,2)

The coordinates of the polygon WXYZ are:

W = (-4,-1)

X = (-2,-1)

Y = (-2,-4)

Z = (-3,-2)

When reflected across the y-axis, the rule of transformation is:

(x,y) -> (-x,y)

So, we have:

W' = (4,-1)

X' = (2,-1)

Y' = (2,-4)

Z' = (3,-2)

When rotated by 180 degrees, the rule of transformation is:

(x,y) -> (-x,-y)

So, we have:

W" = (-4,1)

X" = (-2,1)

Y" = (-2,4)

Z" = (-3,2)

Hence, the coordinates of the final vertices of the two transformations are W" = (-4,1), X" = (-2,1), Y" = (-2,4) and Z" = (-3,2)

The solutions of the given equation are x = 4 or x = -5.

The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations.

Given is an equation, 3(x – 4)(x + 5) = 0 we need to find the solution of the equation,

So, we can see that the equation is a quadratic equation, so it will have two solutions,

The equation is already in factored form,

So,

3(x – 4)(x + 5) = 0

Solution,

x-4 = 0

x = 4

x+5 = 0

x = -5
