The equation of the line that passes through the point (10, -4) and has the slope -2/5 is y = 2/5 x
How to identify the equation of the lineThe slope, m of the linear function is given as -2/5.
The equation of the line that passes through point (10, -4) is calculated using the point slope formula which is given as:
x₁ = 10
y₁ = -4
m = -2/5
substituting in to the formula
(y - y₁) = m (x - x₁)
y + 4 = -2/5 (x - 10)
y + 4 = -2/5 x + 4
y = 2/5 x + 4 - 4
y = 2/5 x
The equation of the line is given as y = 2/5 x

dani had $200 in her savings account. When she turned 18, the bank began charging her a $5.00/month fee. Write a function in terms of a for the balance of her savings account if she doesn't notice the monthly fee.
Complete the following. Use standard slope-intercept form.
We can write a function in terms of 'a' for the balance of Dani's savings account if she doesn't notice the monthly fee as:
f(a) = 200 - 5a
where 'a' represents the number of months that have passed since Dani turned 18 and the bank began charging her the monthly fee.
So, f(0) = 200 represents the initial balance in Dani's savings account when she turned 18.
f(1) = 200 - 5(1) = 195 represents the balance in Dani's savings account after 1 month.
f(2) = 200 - 5(2) = 190 represents the balance in Dani's savings account after 2 months and so on.
Therefore, the function f(a) = 200 - 5a represents the balance of Dani's savings account after 'a' number of months if she doesn't notice the monthly fee.

What is its frequency?
The frequency of the motion is given as follows:
0.0318 Hz.
How to obtain the frequency of the motion?A standard cosine function is defined as follows:
g(x) = acos(b(x+c))+d.
The coefficients have these following roles:
a: amplitude.b: The period is of 2π/B.c: phase shift.d: vertical shift.Hence we must look first at coefficient b to obtain the period of the function.
The coefficient b is given as follows:
b = 0.2.
Hence the period of the function is of:
p = 2π/0.2
p = 10π.
The frequency is one divided by the period, hence:

What is the image point of ( 6 , 5 ) after the transformation D 5 ∘ 0 ∘T 0,0 ?
The image point of P(x,y) = ( 6 , 5 ) after applying a horizontal reflection is P'(x,y) = (1, 5).
How to determine the image after transformation?In geometry, a rigid transformation is a transformation applied onto a geometric object such that Euclidean distance in every point of it is conserved. Translations are examples of rigid transformations and are defined by this formula:
P'(x,y) = P(x,y) + T(x,y) (1)
Where:
P(x,y) - Original point
T(x,y) - Translation vector
P'(x,y) - Image point
If we know that P(x,y) = (6, 5) and T(x,y) = (5, 0), then the image point is:
P'(x,y) = (6, 5) + (5, 0)
P'(x,y) = (1, -6)

-3x-3y=3 solve by substitution
Answer: x = 2, y = -3
Step-by-step explanation: From the question,
-3x -3y = 3 ---------- this becomes the first equation
Make y the subject
-3y = 3 + 3x
y = (3 + 3x)/ -3 ----------this becomes our second equation
Substitute the value of y into the first equation
-3x -3(3 + 3x) = 3
-3x -9 + 9x = 3
Collect like terms
-3x + 9x = 3 + 9
6x = 12
Divide both sides by 6
6x/ 6 = 12/ 6
x = 2
Substitute x = 2 into the second equation to find y
y = (3 + 3(2) )/ -3
y = ( 3 + 6) / -3
y = 9/ -3

How to Determine if Three Side Lengths Are a Triangle?It's simpler than it seems to determine whether a triangle has three side lengths. The Triangle Inequality Theorem, which asserts that the sum of a triangle's two side lengths is always greater than the third side, will suffice. You will have a triangle if this holds true for each of the three possibilities of increased side lengths.
Theorem of Triangle Inequality. This theorem merely states that the third side of a triangle cannot be smaller than the total of the first two sides. You will have a valid triangle if this holds true for each of the three possible combinations. To confirm that the triangle is feasible, you will need to go through each of these combinations one at a time. Theorem a+b > c, a+c > b, and b+c > a can alternatively be thought of as an inequality. The triangle has sides of lengths a, b, and c.

What is the additive inverse of 3 /- 7?
The additive inverse of 3/-7 is -3/7. This means that when 3/-7 is added to its additive inverse, the result is 0.
The additive inverse of any number is the number with the same absolute value but with the opposite sign. Therefore, the additive inverse of 3/-7 is -3/7. When two numbers are added together, the signs of the numbers can affect the result. For example, when two negative numbers are added, the result is a negative number. When two positive numbers are added, the result is a positive number. When one number is positive and one number is negative, the result depends on the relative size of the two numbers. For example, if the positive number is larger than the negative number, the result is a positive number. However, if the negative number is larger than the positive number, the result is a negative number. In the case of 3/-7, the negative number is larger than the positive number, so the result of adding 3/-7 to its additive inverse is 0.

(a) Find the vertical distance fallen in 6 seconds.
(b) If the ball is dropped from a height of 240 m, find the time it takes to hit the ground.
Answer:
180 m , ≈ 6.9 seconds
Step-by-step explanation:
let vertical distance be represented by d and time t
given d is directly proportional to t² , then the equation relating them is
d = kt² ← k is the constant of proportion
to find k use the condition , the ball falls 80 m in 4 seconds , then
80 = k × 4² = 16k ( divide both sides by 16 )
5 = k
d = 5t² ← equation of proportion
(a)
when t = 6
d = 5 × 6² = 5 × 36 = 180 m
(b)
when d = 240
240 = 5t² ( divide both sides by 5 )
48 = t² ( take square root of both sides )
[tex]\sqrt{48}[/tex] = t , that is

How do you determine if three points are in a straight line in 3D?
To determine if three points are in a straight line in 3D, you can calculate the vector between the first two points and then check if the third point is in the same direction as the vector.
What is straight line?Straight line is a line that extends infinitely in two opposite directions and has no curves or bends. It is the shortest distance between two points and is the basic form of geometry. A straight line is composed of two end points and all the points in between that make up the line. Straight lines are used to create shapes and constructions in mathematics, science and engineering.
If the dot product of the vector and the point is 0, then the three points are in a straight line. Alternatively, you can calculate the area of the triangle formed by the three points and if it is 0, then the points are in a straight line. Another option is to calculate the determinant of the matrix formed by the three points and if it is 0, then the points are in a straight line. Finally, you can calculate the angle between the two vectors formed by the three points and if it is 0, then the points are in a straight line.

According to the table for a $150,000 mortgage, Lastri's credit score needs to improve by 62 points for her to take a mortgage for $150,000.
What is the credit score?The credit score refers to an individual's or entity's creditworthiness rating.
The credit score predicts a person's credit behavior and ability to repay credit.
Financial institutions and lenders use the credit score to determine the amount of credit to offer a borrower, the attached credit risks, and the accompanying interest rate, including monthly payments.
Annual mortgage payments Lastri can afford = $13,900
Monthly payment = $1,158 ($13,900 ÷ 12)
Current credit score = 498
Minimum credit score for a monthly payment of $1,158 = 560
Additional credit score improvement = 62 (560 -498)

What is a constant of dilation?
A constant of dilation is a number used to change the size of a figure while preserving its shape. It is also known as a scale factor.
The constant of dilation is used in a dilation transformation, a type of transformation that changes the size of a figure without changing its shape or orientation.
The constant of dilation is typically represented by the letter "k" and is a number greater than 0. If the constant of dilation is greater than 1, the dilation will increase the size of the figure. If the constant of dilation is less than 1, the dilation will reduce the size of the figure. And if the constant of dilation is equal to 1, the dilation will not change the size of the figure.
It's important to note that the constant of dilation is a factor that applies to all the points of the figure, and it's the same for all the points of a figure during a dilation transformation.
