Find the equation of the line that passes through the points (-4,3) and (10,5). Plug in your slope and y-intercept, or your values for a and b into the equation below (if your answers are not whole numbers leave them as fractions!).
y =_____x+______
Answer:
y = 1/7x + 25/7
Step-by-step explanation:
Find the slope using the formula [ y2-y1/x2-x1 ]
5-3/10-(-4)
2/14
1/7
Find the y-intercept using slope-intercept form [ y = mx + b ], the slope, and one of the points given.
y = 1/7x + b
3 = 1/7(-4) + b
3 = -4/7 + b
3 4/7 = b
Put everything we solved for back into the formula.
y = 1/7x + 25/7

Step-by-step explanation:
- 10x - y = 27
- 4x - y = 9
Find the solution of the system equation.
Step-by-step explanation:
-10x - y = 27 ...1
-4x - y = 9 ...2
...1 - ...2
-10x -y - (-4x - y) = 27 - 9
-10x -y +4x + y = 18
-10x + 4x = 18
-6x = 18
x = 18/(-6)
= -3
Answer:
x = - 3, y = 3
Step-by-step explanation:
Given the 2 equations
- 10x - y = 27 → (1)
- 4x - y = 9 → (2)
Multiplying (1) by - 1 and adding to (2) eliminates the term in y
10x + y = - 27 → (3)
Add (2) and (3) term by term to eliminate y
6x = - 18 ( divide both sides by 6 )
x = - 3
Substitute x = - 3 into either of the 2 equations and solve for y
Substituting into (2)
- 4(- 3) - y = 9
12 - y = 9 ( subtract 12 from both sides )
- y = - 3 ( multiply both sides by - 1 )
y = 3
Solution is x = - 3, y = 3

Suppose A and B are points. What is the maximum number of distinct lines that contain both A and B?
Answer:
Step-by-step explanation:
there would be one distinct line
Points and lines are both undefined terms of geometry.
The maximum number of distinct lines that contain both A and B is 1
From the question, we have:
[tex]Points = 2[/tex] --- i.e. A and B
For any given 2 points, only one line can run through the points. In other words, only one line can run through point A and point B
The line can:
Start from point A and end at point BStart from point B and end at point BRun through both pointsHence, the maximum number of distinct lines that contain both A and B is 1

What is an exponential function?In Mathematics, an exponential function can be modeled by using this mathematical expression:
f(x) = ab^x
Where:
a represents the initial value or y-intercept.x represents time.b represents the rate of change.Based on the information provided above, an exponential function which models the situation is given by:
y = 200,000(1.09)^x
For the time between May 7 and May 21, we have:
Time = May 7 to May 21 = 15 days.
Substituting the given parameters into the exponential function formula, we have;
y = 200,000(1.09)^15
y = 200,000(3.6425)
y = 728,500 mosquitoes.

The reason is because y is rise or how far you go down while x is whether you go right or left. Lets use point D for example if we move 7 to the right x is positive then we lower 7 then y is negative that's why I think it's correct.
The bottom of Paul's fish tank is a square shape that has an area of 64 square inches.
Paul wants to buy a decorative square plate to put in the bottom of the tank. What
should be the length of the sides of the plate that Paul buys?
Answer:
Divide the area by 4 which makes 16 so that means that Paul should buy 16 inch plates.
Step-by-step explanation:
The length of the sides of the plate that Paul buys is 16 inches.
Given that,
The area of the square shape is 64 square inches.And, we know that the square contains 4 sides.Based on the above information, the calculation is as follows:
[tex]= \frac{64}{4}[/tex]
= 16

Suppose Jasmine drives from home to the office in 20 minutes. Use this information and part (b) to write an equation.
4.Jasmine drives every morning to her office that is 12 miles from her home.
* What is Jasmine's driving speed in mph?
Solve the equation you created in part (c) to answer the question.
Answer:
1. Her time in minutes is 720/s minutes
2. Given her time to be 20 minutes, her speed is 36 mph
Step-by-step explanation:
Mathematically,
Distance = speed * time
In this question, we want to calculate time;
So time = distance/speed
times = 12 miles/s mph = 12/s hours
Now we want our answer in minutes
Kindly recall that 60 minutes = 1 hour
So 12/s hours will be 12/s * 60 = 720/s minutes
2. Since she drives from home to the office in in 20 minutes, we want to calculate her speed in mph
From the time calculated above i.e 720/s
We can equate 20 = 720/s
20s = 720
s = 720/20
s = 36 mph

The slope of (1,8) and (3,12) is 2 and this can be determined by using two-point slope formula and also using the given data.
Given :
Points -- (1,8) and (3,12)
The following steps can be used in order to determine the slope of (1,8) and (3,12):
Step 1 - The two-point slope formula can be used in order to determine the slope of (1,8) and (3,12).
Step 2 - The two-point slope formula is given by:
