The point (3,-1)( 3 , − 1 ) is a solution to this system of equations:
Answers
The system of equations we have is:
[tex]\begin{gathered} -3x-2y=-7 \\ x+4y=1 \end{gathered}[/tex]And we need to check if the point (3,-1) is a solution.
Step 1. Identify the values of x and y from the point.
In a point, the first number represents the x-value, and the second number represents the y-value. So in point (3,-1) 3 is the x-value, and -1 is the y-value:
[tex]\begin{gathered} x=3 \\ y=-1 \end{gathered}[/tex]Step 2. Substitute the x and y-value into the first equation and check that the result is equal to -7.
The first equation is:
[tex]-3x-2y=-7[/tex]Substituting x=3 and y=-1:
[tex]-3(3)-2(-1)=[/tex]Solve the operations:
[tex]-9+2=-7[/tex]Since we get -7 as the result, (3,-1) is a solution for the first equation. But we still need to check if the point is a solution for the second equation.
Step 3. Substitute the x and y values into the second equation and check that the result is 1.
The second equation of the system is:
[tex]x+4y=1[/tex]Substituting x=3 and y=-1:
[tex]3+4(-1)=[/tex]Solving the operations:
[tex]3-4=-1[/tex]The result we get is -1, not 1. Thus, since the point (3,-1) is not a solution for the second equation, it is also not a solution to the system of equation.

Mr. Jensen purchased an airline ticket on a web site. The original price of the airline ticket was $473.00. He used a coupon code to receive a 20% discount. A sales tax of 12% was applied after the discount. What was the total purchase price of the airline ticket after the discount, including sales tax?
A $105.92
B $332.99
C $423.81
D $529.76
Answers
The price of the online ticket after discount, including sales tax, is $423.81.
What is percentage?Percentage is a measurement to find the value of a given number out of a hundred.
Given that,
The original price of the airline ticket = $473
Discount after applying coupon code = 20%
The price after applying coupon code = 473x4/5 = 378.4
Since, there is a sales tax of 12%,
So the price of airline ticket after sales tax = 378.4 x 112/100 = 423.808
The price of online ticket after discount and including sales tax is $423.81

You are tasked with analyzing a design that has been drawn for a bridge over an existing two-lane road. The arch over the road is in the shape of a half-ellipse that is 40 feet wide at the base of the arch and it is 15 feet tall at the center of the arch. The bridge must have a 13-foot clearance for vehicles on the road. The 22-foot-wide road is centered directly beneath the highest point of the arch. a) the semi-truck will NOT be able to pass under the bridge,so it is time to make an adjustment. You will need to modify the design of the bridge. Keep the arch shape as half an ellipse, and the base as 40 feet wide. You may adjust the bridge’s arch up to 18 feet above the center line of the two-lane road below, but no more than that because of restrictions concerning the road crossing over the bridge. Give a new equation for the ellipse that represents your modified design.
Answers
We are asked to determine the equation of an ellipse that has a base of 40 feet and a height of 18 feet. This can be visualized in the following diagram:
The general form of the equation of an ellipse is:
[tex]\frac{x^2}{a^2}+\frac{y^2}{b^2}=1[/tex]We have set the origin of the coordinate system to be in the middle of the ellipse. The value of "a" is the x-intercept of the ellipse and the value of "b" is the y-intercept of the ellipse. Therefore, the equation is:
[tex]\frac{x^2}{(20)^2}+\frac{y^2}{(9)^2}=1[/tex]Now, we solve the squares:
[tex]\frac{x^2}{400}+\frac{y^2}{81}=1[/tex]And thus we have determined the equation of the ellipse.

What are equations?A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.Like this: 2x - 4 Equals 2. In the above example, the variable x exists.So, to find the value of x, we will solve the equation:
7(x/9) + 2 = 25/9
Now, solve this equation as follows:
7(x/9) + 2 = 25/9
7x/9 = 25/9 - 2
7x/9 = 7/9

2) Preserves both angles and distance.
3) Preserves only angles but not distance
How to Interpret Transformation of Objects?
In transformations, there are different types such as dilation, reflection, translation, rotation, e.t.c
1) Dilation of a quadrilateral by a scale factor of 2;
When we dilate by a scale factor of 2, it simply means we are enlarging the side lengths by a scale factor of 2. Thus, the side lengths will increase but angles remain the same.
2) Translation of a rhombus 3 units to the right and then a reflection across the x-axis;
When we translate an object, it means we just move it from one point to the other and this means that the length and angles do not change, Similarly, reflection is just a mirror image and it also means that the length and angles do not change.
3) Translation of a triangle 2 units to the left and then a dilation by a scale factor of 5 about the origin;
This will end up changing the side lengths but not the angles.
