Yes, Gerri is correct and if a number is a multiple of 9 it is also a multiple of 3.

What is a factor?

A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product because the product is divisible by them.

Here, we have

Gerri says that if a number is a multiple of 9 it is also a multiple of 3.

Since 3 is a factor of 9, anything 9 can go into, 3 can also go into.

3x3=9

So, whenever 9 can go into something, it will take 3 times as many 3s to go into that number.

Example:

3 nines = 27

9 threes = 27

9 is 3 times as many as 9.

Hence, Gerri is correct and if a number is a multiple of 9 it is also a multiple of 3.

Step-by-step explanation:

The equation that represents h(x) = g(x) – f(x) which is correct answer would be option (D)

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

From the given table, the values of x, f(x), g(x), and h(x) are given and there are corresponding values.

Therefore, the corresponding values for

When x = 1

f(x) = 3

g(x) = 18

h(x) = 18 - 15 = 3

When x = 2

f(x) = 12

g(x) = 21

h(x) = 21 - 12= 9

When x = 3

f(x) = -3

g(x) = 24

h(x) = 24 - (-3) = 27

Hence, The equation that represents h(x) = g(x) – f(x).

Answer:

An equation represents a circle with its center at (2, -3) and that passes through the point (6,2) is:

(x - 2)² + (y + 3)² = 41

Step-by-step explanation:

The standard equation of a circle having the center at point C(x₀, y₀) and radius r is given by

(x - x₀)² + (y - y₀)² = r²

It means that every point  P(x, y) belonging to the circle must satisfy the equation.

In this particular case, we have that the circle passing through P(x, y) = (6, 2) and the center C(x₀, y₀) = (2, -3).

Then substituting these values in the formula:

(x - x₀)² + (y - y₀)² = r²

(6 - 2)² + (2 - (-3))² = r²

switch sides

r² = (6 - 2)² + (2 - (-3))²

r² = (4)² + (2 + 3)²

r² = (4)²+ (5)²

r² = 16 + 25

r² = 41

r = √41, r = -√41

As r can not be negative, so

r = √41

Therefore , the equation of the circle with center at C = (2, -3) and radius r = √41 is:

(x - 2)² + (y + 3)² = (√41 )²

(x - 2)² + (y + 3)² = 41

Therefore, an equation represents a circle with its center at (2, -3) and that passes through the point (6,2) is:

(x - 2)² + (y + 3)² = 41  

Answer:

4x+14

Step-by-step explanation:

we know that in a rectangle, 2 sides are equal to one another (opposite sides), and the other 2 are equal to each other.

so,

2(5x+5) for the first 2 sides. you'd get 10x+10

2(2-3x) for the other two sides. you'd get -6x+4

add them up, and you'd get 4x+14

Answer:

Remember, 3 is the same thing as 3/1. Before we can divide, we need to make one more change. We'll switch the numerator and the denominator of the fraction we're dividing by: 1/3 in this example. So 1/3 becomes 3/1.

The line a and line d are perpendicular to each other.

A perpendicular line is a line that intersect another line at 90 degrees. Perpendicular lines are also called normal lines.

After constructing the two lines; line a and line intersect or meet each other at 90 degrees to the horizontal.

Thus, we can conclude that the line a and line d are perpendicular to each other.

Answer:

7

Step-by-step explanation:

first, we would set up an equation. let 3x-4 represent "four less than a number tripled". "a number" would be represented by x. let x+10 represent "the same number increased by 10".

set 3x-4 and x+10 equal to each other:

3x-4=x+10

next, we would solve this equation for x. first we would get the x together on one side of the equation. we would do this by subtracting x from both sides to remove it from the right side of the equation:

2x-4=10

then, we would get the 2x by itself. we would do this by adding 4 to both sides:

2x=14

finally, we would divide each side of the equation by 2 to find x:

x=7.

The number is 7.

Answer:

Option D: [tex]y=\frac{1}{3}x+2[/tex] is the correct answer.

Step-by-step explanation:

Given that:

Slope of the line = 1/3

Point = (-6,0)

Slope-intercept form of a line is given by:

y = mx + b

We will put the slope and point in the equation to find b.

[tex]0=\frac{1}{3}(-6)+b\\0=-2+b\\b=2[/tex]

Slope intercept form of the given line is;

[tex]y=\frac{1}{3}x+2[/tex]

Hence,

Option D: [tex]y=\frac{1}{3}x+2[/tex] is the correct answer.

Answer:

The pair of shoes is $84

Step-by-step explanation:

he saved 1/4 (25%) of what he needs to buy the shoes. 25 x 4 =100 =full price

21 x 4 =84. and also if you can do 84 - 25% on a calculator, the 25% would turn to 21, or at least in mine it did. Total price of shoes - money saved = money needed to buy shoes, which is $63.

Answer:

m ∠D = 29°

m ∠T  = 105°

Step-by-step explanation:

Given: ΔSTU and ΔDEF

To find: m ∠D and m ∠T

Solution:

According to SSS similarity criteria,

two triangles are said to be similar if their corresponding sides are proportional.

In ΔSTU and ΔDEF,

[tex]\frac{ST}{DE}=\frac{15}{6}=\frac{5}{2} \\\\\frac{TU}{EF}=\frac{10}{4}=\frac{5}{2}\\\\\frac{SU}{DF}=\frac{20}{8}=\frac{5}{2}[/tex]

So,

[tex]\frac{ST}{DE}=\frac{TU}{EF}=\frac{SU}{DF}=\frac{5}{2}[/tex]

Therefore,

ΔSTU ≈ ΔDEF

If two triangles are similar then measure of their corresponding angles are equal.

m ∠D = m ∠S = 29°

m ∠U = m ∠F = 46°

In ΔSTU,

m ∠S + m ∠T + m ∠U = 180°

29° + m ∠T + 46° = 180°

75° + m ∠T = 180°

m ∠T  = 180° - 75° = 105°

(According to angle sum property of a triangle, sum of measures of angles of a triangle is equal to 180°)
