Write an expression for the length of the third side of an isocoles triangle
Answer:
[tex]y = 180 - 2x[/tex]
Step-by-step explanation:
Required
Triangle: Isosceles
Required
An expression for the third side
Let the equal sides be x and the third side be y
From triangle sum theorem, we have the following expression:
[tex]x + x + y = 180[/tex]
[tex]2x + y = 180[/tex]
Subtract 2x from both sides
[tex]-2x +2x + y = 180 - 2x[/tex]
[tex]y = 180 - 2x[/tex]
Hence, the third side of an isosceles triangle is: [tex]y = 180 - 2x[/tex]
Describe what a frequency table is what is used for
Answer:
A frequency table shows the distribution of observations based on the options in a variable. Frequency tables are helpful to understand which options occur more or less often in the dataset. This is helpful for getting a better understanding of each variable and deciding if variables need to be recoded or not.
Step-by-step explanation:
hope this helps! :)
The usage of frequency table is to create graphs such as histograms, bar charts, and pie charts to visualize the data.
We are given that;
The frequency table
Now,
A frequency table is a table that lists items and shows the number of times the items occur. It is a way of organizing data and summarizing how often each value or category appears in a dataset.
Frequency tables can be used for any type of variable, such as categorical, ordinal, or numerical.
Frequency tables can help us to understand the distribution of data, identify patterns, and compare different groups.
For example, suppose we have a dataset of 20 students' favorite colors. We can make a frequency table to show how many students prefer each color:
| Color | Frequency |
| ----- | --------- |
| Red | 5 |
| Blue | 7 |
| Green | 4 |
| Yellow| 2 |
| Pink | 2 |
Therefore, by the table answer will be to create graphs such as histograms, bar charts, and pie charts to visualize the data.

The system of equation which have no solution are A, B and D.
What is a slope ?Slope defines rate of change or we can also say it is rise over run.
According to the given question we have to determine given system of equations which have no solution.
We know when two lines are parallel to each other they have no solution cause they have no common intersection points and we also know parallel lines have same slope with different y intercept.
Let us write all the system of equations in slope intercept form which is
y = mx + b.
A.
y = -3x + 5.
y = -3x + 4.
This system of equation has no solution cause have have same slope and different y intercept hence parallel to each other.
B.
y = 4x - 1.
4y = 16x - 1
y = 4x - 1/4.
Same slope different y intercept so no solution.
C.
-2y = -5x + 3.
y = (5/2)x - 3/2.
-4y = -10x + 6.
y = (5/2)x - 3/2.
Same slope same y intercept so they are on top of another so infinite no. of solutions.
D.
3x + 7y = 42
7y = - 3x + 42.
y = (-3/7)x + 6.
14y = -6x + 50.
y = (-3/7)x + 25/7.
Same slope different y intercept so they are parallel to each other.
E.
y =2x + 5.
y = 5x².
Different slope and y intercept so they are not parallel.

A tree has a shadow 900 inches long. At the same time of day, Evelyn's shadow is 72 inches long. The two triangles formed by the tree, Evelyn, and their shadows are similar right triangles, as shown in the diagram below.
Evelyn is 65 inches tall. What is the height of the tree in inches?
Answer:
812.5 inches
Step-by-step explanation:
Turn these numbers into fractions:
[tex]\frac{h}{900} \frac{65}{72}[/tex]
Solve 900/72 to get 12.5. This means that multiplying 72 x 12.5, you get 900. So, to find the height of the tree: h you multiply 65 x 12.5. Your answer to this is 812.5.

2x+1/2y=7
6x-1/2y=5
Answer:
1) Subtracting one from the other
2) x = 0.375 and y = 0.125
Step-by-step explanation:
Equation 1 :
[tex]\frac{2x+1}{2y}=7\\\\[/tex]
Equation 2:
[tex]\frac{6x-1}{2y}=5[/tex]
To solve these equations by the Elimination method we multiply equation 1 with 6 and multiply equation 2 with 2 so now,
[tex]\frac{2x+1}{2y} =7\\\\2x+1=14y\\\\Multiplying\ Equation\ 1\ with\ 6\\\\12x+6=84y[/tex]
Now for the second equation:
[tex]\frac{6x-1}{2y}=5\\\\6x-1=10y\\\\Multiplying\ equation\ 2\ with\ 2 \\\\12x-2=20y[/tex]
Now subtracting equation 2 from equation 1
[tex]12x+6=84y\\\\12x-2=20y\\\\Subtracting\ leads\ to\\12x-12x+6-(-2)=84y-20y\\0+8=64y\\8=64y\\8/64=y\\0.125=y[/tex]
now insert this value of y into any equation
lets insert it into equation 1
[tex]\frac{2x+1}{2y} =7\\\\2x+1=14y\\2x+1=14(0.125)\\2x+1=1.75\\2x=1.75-1\\2x=0.75\\x=0.75/2\\x-0.375[/tex]

The statements in the two column proof can be explained as follows;
Statement [tex]{}[/tex] Explanation
1. p║q [tex]{}[/tex] Given
∠1 ≅ ∠11
2. ∠1 ≅ ∠9 [tex]{}[/tex] Corresponding angles on parallel lines crossed by a common transversal are congruent
3. ∠9 ≅ ∠11 [tex]{}[/tex] Transitive property of equality
Given that ∠1 ≅ ∠11 and we have that ∠1 ≅ ∠9, then we can transit the terms between the two expressions to get, ∠9 ≅ ∠11 which is the same as ∠11 ≅ ∠9
4. a║b [tex]{}[/tex] Corresponding angles on parallel lines are congruent
Whereby we now have ∠9 which is formed by line a and the transversal line q, is congruent to ∠11 which is formed by line b and the common transversal line q, and both ∠9 and ∠11 occupy corresponding locations on lines a and b respectively which are crossed by the transversal, line q, then lines a and b are parallel to each other or a║b.

A function, f(x) = x, is vertically translated 4 units up and then reflected across the y-axis. What's the new function in terms of g(x)?
Answer:
The new function is g(x) = -x + 4
Step-by-step explanation:
If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k If the function f(x) reflected across the y-axis, then its image is g(x) = f(-x)∵ A function f(x) = x
∵ It is vertically translated 4 units up
→ By using the 1st rule above, the value of k = 4
∴ k = 4
∵ Its image h(x) = f(x) + k
∴ Its image h(x) = f(x) + 4
∴ Its image h(x) = x + 4
∵ Then it is reflected across the y-axis
→ By using the 2nd rule above, change the sign of x in h(x)
∵ h(x) = x + 4
∴ g(x) = h(-x)
∴ g(x) = -x + 4
∴ The new function is g(x) = -x + 4
