The length of segment VY, represented by "a," is 25x - 21.
How to find the length of the segmentTo find the length of segment VY, we can use the fact that W is the midpoint of VY. The midpoint of a line segment divides it into two equal parts. Therefore, the length of VW plus the length of WY equals the length of VY.
Let VY be represented by "a." Then, according to the midpoint property:
VW + WY = VY
Substitute the given expressions for VW and WY:
(9x + 7) + (16x - 28) = a
Now, combine like terms:
25x - 21 = a
So, the length of segment VY, represented by "a," is 25x - 21.

The value of a phone when it was purchased was $500. It loses 1/5 of its value a year. What is the value of the phone after 1 year, 2 years, and 3 years?
Answer:
$200
Step-by-step explanation:
1/5 of 500 is 100 because 5 100s equal 500. so 3 years is 300. 500-300=200
Identify the slope of the line. Interpret the slope in the context of this problem. Y=-2.3332x+123.98
Answer:
Slope = 2.3332
Interpretation: As increases by 1 unit, y increases by 2.332 units
Step-by-step explanation:
Equation of a line in slope-intercept form is
y = mx + b
where m = slope and b = y-intercept
Comparing y=-2.3332x+123.98 to the standard equation form we get
m = 2.3332
b = 123.98
Slope is rise/run
It tells you the change in y-value for a unit change in x-value
Here 2.332 can be interpreted to mean that as x changes by +1 value, y changes by + 2.332
The average age of 8 men, 7 women and 1 boy is 45 years, that of 8 men being 48 years and of 7 women
being 46 years, determine the age of the boy.
The age of the boy is 14 years.
Given average age of 8 men, 7 women and 1 boy is 45 years.
Averages are used to condense a vast number of data points into a single value. It is a visual depiction of all the data set's available numbers. By adding up all the data values and dividing them by the total number of data points, the average is calculated.
age of 8 men is 48 years.
age of 7 women is 46 years.
age of the boy is = ?
= (45 ×16 ₋ 48 × 8 ₋ 7 × 46)
= (720 ₋ 324 ₋ 322)

What does area in math mean?
Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies. Consider your square as being composed of smaller unit squares.Area of pool = πr² = π(12)²= 452.4 ft²
area of house = 25 × 50 = 1250 ft²
area of ratio = 40 × 10 = 400 ft²
area of drive = 30 × 10 = 300 ft²
area of shed = 10 × 8 = 80 ft²²
total are all combined for above will be = 2482.4 ft²
total area of plot = 200 × 100 = 20000 ft²
lawn area = 20000 - 2482.4 = 17517.6 ft²
on converting ft² into yard²
lawn area = 17517.6 ft² = 1946.4 yard²
cost of each yard² = $0.03

Give the equation of the line with a slope of - 5/7 and a y intercept of 5
Answer:

Step-by-step explanation:
The equation of a line can be written in the form of y= mx +c, where m is the slope and c is the y-intercept. This is also known as the slope-intercept form.
Identify the value of the slope, m:
Given that the slope is [tex]-\frac{5}{7}[/tex], m= [tex]-\frac{5}{7}[/tex].
Substituting the value of m into the equation:
[tex]y=-\frac{5}{7} x+c[/tex]
Identify the value of the y-intercept:
Given that the y-intercept is 5, c= 5.
Substitute c= 5:

Write an equation of the form y=a sin b x or y=a cos b x to describe the graph below.
Greetings from Brasil...
In a trigonometric function of Cosine, we have:
F(X) = ±A ± B.COS(MX + N)where
A = move the graph up or down
B = change the amplitude
M = change period
N = move the graph left or right without distorting it
According to the statement, we don't have A and N, so
F(X) = ± B.COS(MX)
According to the graph presented, we have:
B = amplitude = 2.5 = 5/2
period = π

Period = 2π/M
π = 2π/M ⇒ M = 2

The summative product of B⁴ + [tex]M^{y}[/tex] is; [tex]M^{8y} + M^{y}[/tex]
How to use Laws of Exponents?We are given the equation as;
B⁴ + [tex]M^{y}[/tex]
Now, we are further told that;
B = [tex]M^{2y}[/tex]
Thus, we have our original expression as;
[tex](M^{2y})^{4}[/tex] = [tex]M^{y}[/tex]
According to laws of exponents, we know that;
When multiplying like bases, the same bases are kept and we add the exponents. When raising a base with a power to another power, retain the base the same and multiply the exponents. When dividing like bases, keep the base the same and subtract the denominator exponent from the numerator exponent.Thus; (x²)³ = x²*³ = x⁶
Applying that to our expression means we now have;
[tex]M^{8y} + M^{y}[/tex]
Thus, the summative product of B⁴ + [tex]M^{y}[/tex] is; [tex]M^{8y} + M^{y}[/tex]
