Answer:

A (0,3)

Step-by-step explanation:

The given trapezoid has vertices:

(0,6), (7,12), (7,9) and (0,12).

We want to choose from the given options, a point that is a vertex for the image produced by a dilation about the origin with a scale factor of 1/2.

Note that the mapping for such a dilation is:

[tex](x,y)\to( \frac{1}{2} x, \frac{1}{2} y)[/tex]

This implies that:

[tex](0,6)\to(0,3)[/tex]

[tex](7,12)\to(3.5,6)[/tex]

[tex](7,9)\to(3.5,4.5)[/tex]

[tex](0,12)\to(0,6)[/tex]

Therefore correct choice is (0,3)

Answer:

Equation for total number of balls = 8x+6x+5x =19x where x represent a single tennis ball.

Step-by-step explanation:

Given that Kayla has;

8 red tennis balls

6 green tennis balls

5 blue tennis balls

Let;

red tennis ball be r

green tennis balls be g

blue tennis balls be b

The total number of tennis balls is 8+5+6=19 balls

Multiplication is a repeated form of addition where ;

5*5*5 = 3*5= 5+5+5= 15

In this case, r+g+b=19 but r ,g and b are not repeated thus applying multiplication equation will not give the sum of the balls

However if you let a single ball to be represented by x then a single ball x will be multiplied by the number of balls in that category to get the total number of balls per color

For red balls= 8x

For green balls=6x

For blue balls=5x.

Total number of balls = 8x+6x+5x =19x where x represent a single tennis ball.

To find the total number of tennis balls Kayla has, she needs to add the number of each color of balls together, not multiply. When she adds 8 red, 6 green, and 5 blue balls, she gets 19 tennis balls in total.

In this case, Kayla doesn't need to use a multiplication equation to find out the total number of tennis balls she has. Rather, she just needs to add the numbers together. Kayla has 8 red tennis balls, 6 green tennis balls, and 5 blue tennis balls. So, to figure out how many tennis balls she has in total, she simply adds these numbers together: 8 + 6 + 5 = 19 tennis balls in total.

In this problem, we know that Harry saved $100 each week for 8 weeks. In other words, he saved a total amount of money:

[tex]\text{Amount of money saved}=8\times 100=\$800[/tex]

We know that he earned $48 on his savings of $800, so for every $100 the interest (I) he earns is:

[tex]I=\frac{48}{8}=\$6[/tex]

So, in conclusion Harry did earn $6 in interest for every $100

Step-by-step explanation:

the coordinate of k would be (-6,10.5)

Answer:

The multiplication property of equality states that if two values a and b are equal when you multiply each by the same value c, the products are equal.

Step-by-step explanation:

Multiplication property of equality:

So, if

[tex]a = b[/tex]

Then, we can write by multiplication property of equality

[tex]a=b\\\Rightarrow a\times c = b \times c\\\Rightarrow ac = bc[/tex]

Thus, the correct answer is

The multiplication property of equality states that if two values a and b are equal when you multiply each by the same value c, the products are equal.

Final answer:

The statement in question highlights the equality property of multiplication, which states that if two values are equal, their products with a same multiplier are also equal. This principle is fundamental in mathematics, particularly in algebra, where it underpins the manipulation and understanding of equations.

Explanation:

The statement "if two values a and b are equal when you multiply each by the same value c, the products are equal" refers to the basic principle of the equality property of multiplication in mathematics. This property underlines that if a = b, then a × c = b × c. This fundamental concept is crucial for understanding algebraic expressions and equations, where the manipulation of variables and constants is based on such properties.

For example, if we assert that 3 (number a) and 3 (number b) are equal and we choose to multiply both by 2 (number c), the resulting products, 6 and 6, are indeed equal. This example clearly illustrates how the equality of products remains consistent regardless of the multiplier, as long as the initial quantities are equal.

This principle is foundational in mathematics and serves as a cornerstone for solving equations, thereby reinforcing the understanding that equality is maintained through operations of multiplication by a constant.

Answer:

p = 3n + 2

Step-by-step explanation:

let n be the number of shapes and p the perimeter

We can construct the following table

n : 1    2    3

p : 5   8    11

The differences in p are constant

8 - 5 = 11 - 8 = 3

Thus p = 3n + ?

n = 1 → 3(1) + ? = 5 ⇒ 3 + ? = 5 ⇒ ? = 2

n = 2 → 3(2) + ? = 8 ⇒ 6 + ? = 8 ⇒ ? = 2

n = 3 → 3(3) + ? = 11 ⇒ 9 + ? = 11 ⇒ ? = 2

We require to add 2 to 3n

Thus

p = 3n + 2

Answer: 37%

Step-by-step explanation:

n( green ) = 15

n( yellow) = 18

n(Orange) = 16

Total = 49

P(yellow) = n(yellow) / Total number

P(yellow) = 18/49

P(yellow) = 0.367

converting to percentage

P(yellow) = 0.367 x 100 = 36.7

To the nearest percent

P(yellow) = 37%

Step-by-step explanation:

Slope of v: a=(9-14)/(10-1)=-5/9

Slope of w: b=-1/a=9/5=1.8

Answer:

y = 9

Step-by-step explanation:

Calculate the slope m of line k using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (5, 8) and (x₂, y₂ ) = (2, y)

m = [tex]\frac{y-8}{2-5}[/tex] = [tex]\frac{y-8}{-3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex]

The slope of line l is m = 3, thus slope of line k is

m = - [tex]\frac{1}{3}[/tex]

Equating the 2 slopes for line k

[tex]\frac{y-8}{-3}[/tex] = - [tex]\frac{1}{3}[/tex] ( multiply both sides by - 3 )

y - 8 = 1 ( add 8 to both sides )

y = 9

To find the value of y, we can use the fact that the slopes of Perpendicular lines are negative reciprocals of each other. Using the given information and equations, we can solve for y.

To determine the value of y, we can use the fact that the slopes of perpendicular lines are negative reciprocals of each other. Since line l has a slope of 3, the slope of line k would be -1/3. We can use the slope-intercept form, y = mx + b, to find the equation of line k.

Substituting the coordinates (5, 8) and the slope -1/3 into the equation, we can solve for y.

Using the point-slope form, y - y1 = m(x - x1), where (x1, y1) is the given point (2, y). We can rearrange this equation to get y = mx + b form, substitute the values, and solve for y to find the value of y.

Using the cost equation C = $25 + ($1.50 x M), we solve for the greatest number of miles Kelly can travel with an $80 budget, which is 36 miles after rounding down to the nearest whole number.

To determine the greatest number of miles Kelly can travel, we use the equation provided by the truck rental company. The total cost of renting a truck is composed of a one-time fee and a per-mile charge. To begin, we subtract the one-time fee from the total budget to find out how much money is left for the per-mile charges.

The equation representing the total cost (C) for the miles (M) driven is:

C = $25 + ($1.50 × M)

Kelly has $80 to spend, so we set the total cost equal to $80:

$80 = $25 + ($1.50 × M)

Now, we solve for M:

$55 = $1.50 × M

M = $55 / $1.50

M = 36.67

Since Kelly cannot travel a fraction of a mile, we round down to the nearest whole number. The greatest number of miles Kelly can travel is 36 miles.
