1. How can you prove that a line parallel to one side of a triangle divides the other 2 sides proportionally?
2. In an isosceles triangle, how do you prove the base angles are congruent?
Answer:
1. You can prove that a line parallel to one side of a triangle divides the other 2 sides proportionally by using the Triangle Proportionality Theorem.
2. You prove the base angles are congruent by constructing the angle bisector through the vertex angle of an isosceles triangle. By constructing the angle bisector, we designed two congruent triangles and then used CPCTC to show that the base angles are congruent.

You purchased a computer for your business for $800. Using straight-line depreciation, the amount of depreciation allowed for each year after the purchase is given by the function f (x) = 800 − 114.29x. What type of function can you use to model the data?
Answer:
linear function
Step-by-step explanation:
The given function is linear function.
What is linear function?A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3[tex]x[/tex] - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with g([tex]x[/tex]), this function can be written as g([tex]x[/tex] )= 3[tex]x[/tex] - 2.
A linear function is of the form g([tex]x[/tex]) = m[tex]x[/tex] + b where 'm' and 'b' are real numbers. Here,
'm' is the slope of the line'b' is the y-intercept of the line'[tex]x[/tex]' is the independent variable'y' (or g([tex]x[/tex])) is the dependent variableGiven:

Answer:
y=9
9+6=15
y+6=15
Step-by-step explanation:
3+3+16+19+y=41+y
41+y/5=10
multiply both sides by 5
205+y/5=50
41+y=50
Rearrange the equation so y is isolated.
y= 50-41
y=9

Norma Ann planned a rectangular courtyard, as shown in the scale drawing below. She decides to change the width, the shorter side of the courtyard, from 45 ft to 40 ft. Which expression finds the change in the scale factor? PLSS HELP!
Answer: 45 / 40 ft
Step-by-step explanation:
Given that She decides to change the width, the shorter side of the courtyard, from 45 ft to 40 ft. Which expression finds the change in the scale factor?
Actual width of shorter side = 45 ft
New width of shorter side = 40 ft
Scale factor is the ratio of the actual length to the new or intended length
Scale factor = Actual width / New width
Hence, scale factor :
45 ft / 40 ft

The width of a rectangle is 5 feet less than the length. The perimeter is 62. Find the length and width of the rectangle.
Variables: ___________________________
Model equation: ______________________________
Length of the rectangle: ______________________________
Width of the rectangle: ______________________________
Perimeter formula: p = 2(w + l)
The perimeter is 62.
p = 62
The width of a rectangle is 5 feet less than the length.
w = l - 5
Substitute and solve.
62 = 2[(l - 5) + l)]
62 = 2l + 2l - 10
62 = 4l - 10
72 = 4l
18 = l
Substitute and solve for the width
w = 18 - 5
w = 13
Therefore, the length is 18 and the width is 13.
Best of Luck!
Answer:
see below and attached.
Step-by-step explanation:
Perimeter (P) = 2 L (Length) + 2 W (Width)
where P = 62
W = L - 5
P = 2L + 2W
62 = 2L + 2(L -5)
62 = 2L + 2L - 10
72 = 4L
L = 72/4
L = 18
W = L - 5
W = 18 - 5
W = 15
Variables : P, L, W
Model equation: P = 2L + 2W
Length of the rectangle: 18
Width of the rectangle: 13

In the following figure, three layers of cubes are stacked on top of each other. How many cubes of any size are in the figure?
Answer:
14
Step-by-step explanation:
It's 3x3, 2x2, and 1x1
9+4+1=14
Answer:
14 cubes
Step-by-step explanation:
The figure, there are 3 layers, so we can split up the layers.
In the 1st layer is just 1 cube.
In the 2nd layer:
2 x 2 = 4 cubes.
In the 3rd and final layer:
3 x 3 = 9 cubes.
We then add them:
1 + 4 + 9, giving us a total of 14 cubes.

What is a reflection of transformation?A reflection is a type of transformation. It maps one shape onto another. The function retains its basic shape; however, by including a negative sign in the appropriate place in the equation, the graph of the function will flip over one or the other of the axes.
For the given situation,
The options shows the different figures. we need to select the figure that correctly demonstrates the reflection.
Option A:
Here, the figure is not flipped on the axes.
The figure in option A does not show the transformation of reflection.

Answer:
[tex]x=7[/tex]
Step-by-step explanation:
[tex]\sqrt{3x+8}=\sqrt{4x+1}[/tex]
Square both sides:
[tex](\sqrt{3x+8})^{2} =(\sqrt{4x+1})^{2}[/tex]
[tex]3x+8=4x+1[/tex]
Subtract 8 from both sides:
[tex]3x+8-8=4x+1-8[/tex]
[tex]3x=4x-7[/tex]
Subtract 4x from both sides:
[tex]3x-4x=4x-7-4x[/tex]
[tex]-x=-7[/tex]
Divide both sides by -1:
