Answer:
The equation is y = 5x + 4.
--
Step-by-step explanation:
☆Remember: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
☆Slope-intercept: [tex]y = mx + b[/tex]
---
☆We need to find the slope first. So just plug in according to the slope formula!
[tex]m = \frac{9 - 4}{1 - 0} = \frac{5}{1} = 5[/tex]
---
☆Now we need to find the y-intercept. We are going to plug in the slope and a set of coordinates to find the y-intercept.
[tex]y = mx + b \\ 9 = 5(1) + b \\ 9 = 5 + b \\ \frac{ - 5 = - 5 \: \: \: \: \: \: \: \: \: \: \: \: }{4 = b \: \: \: \: \: \: \: \: \: } [/tex]

an activity of 8 minutes each is to be performed by 5 students of class one after the other. the activity starts at 11:10 am with a break of 1 minute between two consecutive activities. when would the activity finish?
Answer:
11:54 a.m
Step-by-step explanation:
Given that:
Length of activity = 8 minutes
Number of students = 5
Nreak length between each consecutive activity = 1 minutes
Start time = 11:10 a.m
Total activity time = Length of activity * number of students = (8 * 5) = 40 minutes
Total. Break time = 1 + 1 + 1 + 1 = 4 minutes
Total length of activity = (40 + 4) = 44 minutes
11:10 a.m + 44 minutes = 11:54 a.m
If 2 hours of TV had 40 commercials, how many commercials were in 1/2 hour?
Answer: 10
Since there are 40 commercials in 2 hours you divide 40 by 2 to find out how many commercials there were in one hour. Then divide by two again bc 1/2 hour is 30 minutes and you get 10.

A triangle has side lengths of 12 inches 14 inches, and 18 inches. What best represents the perimeter of the triangle in centimeters? (1 inch ~ 2.54 centimeters)
Answer:
111.76 cm
Step-by-step explanation:
The formula for the perimeter of a triangle is given as:
Side A + Side B + Side C
Since our final answer is going to be in centimeters we have to convert the sides from inches to centimeters
Hence:
1 inch ~ 2.54 centimeters
For 12 inches
1 inch = 2.54 cm
12 inches = x
Cross Multiply
x = 12× 2.54 cm
x = 30.48 cm
For 14 inches
1 inch = 2.54 cm
14 inches = x
Cross Multiply
x = 14× 2.54 cm
x = 35.56 cm
For 18 inches
1 inch = 2.54 cm
18 inches = x
Cross Multiply
x = 18× 2.54 cm
x = 45.72 cm
Hence, the perimeter of the triangle
= 30.48 cm + 35.56 cm + 45.72 cm
= 111.76 cm

b. $3,496.78
C. $3.322.66
d. $3,381.00
Answer: b. $3,496.78
Step-by-step explanation:
Based on the table, the annual premium for a 20-Year Endowment insurance policy for a 25-year-old healthy male with a face value of $89,753 is $3,322.66. The correct option is C.
What is annual premium?The total amount paid in a year to keep the life insurance policy in force is referred to as the annualized premium.
A life insurance policy's annualized premium does not include taxes or rider premiums.
A premium is the cost of purchasing an insurance policy. Premiums are the monthly payments you make for many common insurance policies, such as life, auto, business, homeowners, and renters.
To find this answer, we look at the male row in the 20-Year Endowment column and find the value that corresponds to age 25. The value is $37.02. Then, we multiply this value by the face value of the policy ($89,753) and divide by 1,000.
($37.02 * $89,753) / 1,000 = $3,322.66
Therefore, the answer is option C.

Find the horizontal distance of a soccer ball being kicked at a 40 degree angle with a velocity of 50 feet per second, to the nearest foot
Answer:
77 ft
Step-by-step explanation:
The horizontal distance is the range and it is a projectile motion.
So, range R = u²sin2θ/g where u = velocity = 50 ft/s, g = acceleration due to gravity = 32 ft/s² and θ = projection angle = 40°.
Substituting the values of the variables into the equation, we have
R = u²sin2θ/g
= (50 ft/s)²sin2(40°)/32 ft/s²
= (2500 ft²/s²)sin80°/32 ft/s²
= (2500 ft²/s²) × 0.9848/32 ft/s²
= 2462.02 ft²/s² ÷ 32 ft/s²
= 76.94 ft
≅ 77 ft to the nearest foot

What is the x-coordinate of the image when M(4, -1) is reflected in y = 3.
Answer:
4
Step-by-step explanation:
y=3 is a horizontal line, so it will not affect the x coordinate.
The x-coordinate of the image when M(4,-1) is reflected in y = 3 is : 4
What is reflection?Reflection is the mirror image of a shape.
It is the process of flipping a shape around a certain axis to look like the original shape.
Analysis:
Since the reflection is at y = 3 which is along the x-axis, only the y coordinate changes. The x coordinate remains the same. So, the x- coordinate is still 4.
In conclusion, the x-coordinate is 4.

B7 formula: =AVERAGE(B3:B6)
B8 formula: =B1*B2*B7
Step-by-step explanation:
There are two parts to finding the answer to the questions posed. (1) You need to understand what you are being asked to calculate. (2) You need to know how to write that calculation as a spreadsheet formula.
It is beyond the scope of this answer to give a tutorial in spreadsheets. Many web sites, videos, books, and other help sources are available to teach you how to open and use a spreadsheet. Presumably, you've been given an introduction in your class.
_____
a) The problem statement tells you that cell B7 contains the average of the values in cells B3 to B6.
The AVERAGE function will compute the average of a range of cells. It can be used in cell B7 to compute the average of the values in cells B3 to B6. The formula would generally be written ...
=AVERAGE(B3:B6)
__
b) Problem 10 doesn't tell you explicitly what the pension formula is. We have to assume that it is similar to the formulas described in problems 8 and 9. That is, it is the product of a percentage, years worked, and the average of some number of salaries. In problem 10, the average is of 4 salaries.
The value in B8 will be the product of the pension credit percentage per year worked, the number of years worked, and the average of the last 4 years' salaries. Those values are in cells B1, B2, and B7, so the formula is written ...
= B1*B2*B7

Which equation has a graph parallel to the graph of 9.x + 3y = -22?
Answer:
y = -3x - 8.3
Step-by-step explanation:
You need to rearrange 9x + 3y = -22 in the form y = mx+c.
9x+3y = -22
3y = -9x - 22
y = -3x - 7.3
As long as the gradient is the same, the lines will be parallel. So you can give any number to the intercept (in this case I gave 8.3) and you will have parallel equations.
Final answer : y = -3x - 8.3
The equation of the line having the parallel graph will be;
⇒ Y = -3x + 8
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
Given that;
The equation of line is,
⇒ 9x + 3y = - 22
Now,
Since, The general form of the equation of the line:-
⇒ y = mx + b
Where, m = slope
b = y-intercept
And, Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
For the parallel lines, the slope of the two lines is always equal.
Here, The given equation will be written as,
⇒ 9x + 3y = -22
⇒ 3y = -9x -22
⇒ y = -3x - (22/3)
Let the equation of the graph is,
⇒ Y = -3x + 8
It has slope = m = dy/dx = - 3
Therefore, the equation of the line having the parallel graph is Y = -3x + 8.
