If Samantha moved point A 9 units down and 6 units to the right, at what point would she end up?
Based on the transformaion of point A, the coordinate of the point she would end up is (3, -4)
How to determine the point she would end up?The complete question is added at the end of this solution
From the question, we have the following point
Starting point = (-3, 5)
The movement is given as
9 units down and 6 units to the right
The above can be represented mathematically as
(x, y) = (x + 6, y - 9)
When the above translation is applied on point A, we have the following equation
A' = (-3 + 6, 5 - 9)
Evaluate the sum and he difference in the above equation
A' = (3, -4)
Hence, the coordinate of the point she would end up is (3, -4)

Find the equation of the line through (7,−2) which is parallel to the line y=−x−4.
Give your answer in the form y=mx+b.
Answer:
y = -x + 5
Step-by-step explanation:
Parallel lines have the same slope, so the slope of the line we need to find is -1. Substituting into point-slope form, we get the equation to be
[tex]y+2=-(x-7)[/tex]
which rearranges into slope-intercept form as follows:
[tex]y+2=-x+7 \\ \\ y=-x+5[/tex]
Answer:
y=-x+5
Step-by-step explanation:
For the linear function f (x) = mx + b, f (-3) = 23 and f (2) = -7.
Find m and b.
Answer:
b = 8 , m = - 5
Step-by-step explanation:
For this question we can use simulteanous equations to solve for m and b.
We first come up with 2 equations.
Given the first condition:
23 = -3m + b
b - 3m = 23 (Equation 1)
Now the Second Condition:
-7 = 2m + b
b + 2m = -7 (Equation 2)
Now, we will use Equation 1 - Equation 2 to eliminate b to solve for m.
-3m - (+2m) = 23 - ( - 7)
- 5m = 30
m = 30 ÷ -6 = -5
Now we substitute m into Equation 1 to solve for b.
b - 3(- 5) = 23
b + 15 = 23
b = 23 - 15 = 8
Answer: m=-6 b=5
Step-by-step explanation:
f(x)=mx+b
f(-3)=23 f(2)=7
[tex]\displaystyle\\\left \{ {{23=(m)(-3)+b} \atop {-7=(m)(2)+b}} \right. \ \ \ \ \left \{ {{23=-3m+b\ \ \ \ (1)} \atop {-7=2m+b\ \ \ \ (2)}} \right.[/tex]
Subtract equation (2) from equation (1):
-30=5m
Divide both parts of the equation by 5:
-6=m
Thus, substitute m=-6 in (2):
-7=(-6)(2)+b
-7=-12+b
-7+12=-12+b+12
5=b
Hence,
y=-6x+5

Four friends went scuba diving today. Ali dove 70 feet, Tim went down 50 feet, Carl dove 65 feet, and Brenda reached 48 feet below sea level. Write the 4 friends’ names in order from the person whose depth was closest to the surface to the person whose depth was the farthest from the surface.
The orders from the person whose depth was closest to the surface to the person whose depth was the farthest from the surface as:
Brenda < Tim < Carlton < Ali
Ascending order is a method of arranging numbers from smallest value to largest value. The order goes from left to right. Ascending order is also sometimes named as increasing order. For example, a set of natural numbers are in ascending order, such as 1, 2, 3, 4, 5, 6, 7, 8… and so on.
If the information is sorted from highest to lowest, it is said to be in descending order. For example 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 are arranged in descending order. In other words, if the numbers are arranged from the largest to the smallest number, it is said to be in descending order.
We can write, four friends went scuba diving today,
Ali dove = 70 feet,
Tim went down = 50 feet,
Carl dove = 65 feet,
Brenda reach = 48 feet below sea level.
To determine the order from the person whose death was closest to the surface to the person whose death was the farthest from the surface.
Arrange in ascending order of distance from sea level.
Brenda < Tim < Carlton < Ali
48feet < 50 feet < 65 feet < 70 feet
Therefore,
The order from the person whose depth was closest to the surface to the person whose depth was the farthest from the surface as:
Brenda < Tim < Carlton < Ali.

Find the value of each follow expression use a title diagram or a number line to help you 3(4)
The value of the expression 3(4) can be expressed as 12 with the help of a title diagram or a number line and the explanation for this same can be done easily if we take into consideration a number line.
What does the math number line mean?A number line is a diagram of a graduated straight line used to represent real numbers in introductory mathematics. It can also be assumed that every point present on a number line corresponds to a real number, and that every real number also corresponds to a point.
To solve this expression, we can deduce as follows:
As per the number line, for the expression 3(4).
Since it is absolutely positive, thus we will get the final answer in positive that means on the side of the number line lying right to zero.
To express this expression,
3 (4) means we have to move towards the right side of the number line from zero for 4 times and each time covering a total of 3 units each.
Thus, we start from zero, first time we reach 3 then 6, then 9 and then finally 12.
Thus, the value of the expression is received as 12.

For a recent year, 34 more Democrats than Republicans represented a country. If the total number of representatives of the country from these two parties was 484, find the number of representatives from each party.
In linear equation the number of Republicans are 225 and the number of Democrats are 259 .
What in mathematics is a linear equation?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.Let Republicans = x
then Democrats = x + 34
x + x + 34 = 484
2x + 34 = 484
2x = 484 - 34
2x = 450
x = 450/2
x = 225
x + 34 = 225 + 34 ⇒ 259
Therefore ,the number of Republicans are 225 and the number of Democrats are 259 .
