How can you use transformations to graph this
function?
y=3.75 +2
Explain your steps.
Answer:
Sketch the graph of y=7^x
Reflect the graph across the y-axis to show the function y=7^-x
Stretch the graph vertically by a factor of 3 to show the function y=3*7^-x
Shift the graph up 2 units to show the function y=3*7^-x+2
Step-by-step explanation:
Answer: Draw a graph showing y=7x. The graph can be reflected across the y-axis to display the function y=7x-x. To display the function y=3*7-x, multiply the graph's vertical extent by 3. The graph should be moved up 2 units to display the function y=3*7-x+2.

Answer:
12) m∠BXD = 122°
13) m∠GXE = 50°
Step-by-step explanation:
12) m∠BXD = ∡BXC + ∡CXF + ∡FXD = 32° + 50° + 40° = 122°
13) m∠GXE = (90° - m∠AXG) = 90° - 40° = 50°

You are paying off a student loan in monthly installments. After
the 4rd payment the remaining balance is $13,900. After the 5th
payment your remaining balance is $13,500. If n is the number of
payments that have been made, what is the nth term rule?
Answer:
The loan will be paid after 39 monthly installments.
Step-by-step explanation:
Since I am paying off a student loan in monthly installments, and after the 4th payment the remaining balance is $ 13,900, while after the 5th payment my remaining balance is $ 13,500, to determine the amount of payments in which the loan was agreed I must perform the following calculation:
13900 - 13500 = 400
400 x 5 = 2000
2000 + 13500 = 15500
15500/400 = 38.75
Thus, the loan will be paid after 39 monthly installments.

On Monday, 30% of the 900 students at Maple Middle school walk to school. Complete the double numberline model. How many students walk to school on Monday?
the answer is 270 (dont click ant links in this app)
270 students walk to school on Monday.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Total students= 900
Percent of student who walk to school= 30%
So, the number of students walk to school on Monday
= 30% of 900
= 30/100 x 900
= 30 x 9
= 270
Hence, 270 students walk to school on Monday.

Answer:
The area of the composite shape is:
122.50 [tex]cm^{2}[/tex]Step-by-step explanation:
To find the area of composite shapes you can pull apart this in known shapes, in this case, a rectangle and a triangle. Taking into account this, we can find the rectangle area firstly:
Rectangle area = base * heightThe base of the rectangle is the measure from down (14 cm) and the height is the measure in the left side (7 cm), with these values we can replace the formula:
Rectangle area = base * heightRectangle area = 14 cm * 7 cmRectangle area = 98 [tex]cm^{2}[/tex]Now, to calculate the area of the remaining triangle, we must use the next formula:
Triangle area = [tex]\frac{base*height}{2}[/tex]Where the base would be equal to the left side of the shape (7 cm) and the height is the difference between the measurement in the top side and the measurement in the bottom side:
Height of the triangle = top side - bottom sideHeight of the triangle = 21 cm - 14 cmHeight of the triangle = 7 cmWe can replace in the formula:
Triangle area = [tex]\frac{7 cm * 7cm}{2}[/tex]Triangle area =[tex]\frac{49cm^{2} }{2}[/tex]Triangle area = 24.5 [tex]cm^{2}[/tex]By last, we must add the two values of the areas obtained:
Area of the composite shape = rectangle area + triangle area.Area of the composite shape = 98 [tex]cm^{2}[/tex] + 24.5 [tex]cm^{2}[/tex]Area of the composite shape = 122.5 [tex]cm^{2}[/tex]Find the total amount given the original price and tip rate. Round to the nearest cent if necessary. Original price: $41.32 Tip: 15%
Answer:
$6.20
Step-by-step explanation:
We can covert 15% to a decimal by moving the decimal point two places over.
15% = 0.15
41.32 X 0.15 = 6.198
6.198 ≈ $6.20
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Original price: $41.32
Tip: 15% = %6.189
Total amount = = Original price + Tip amount
The total amount is $47.509
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Original price: $41.32
Tip: 15%
Now,
The amount of the tip.
= 15% of 41.32
= 15/100 x 41.32
= $6.189
The total amount.
= Original price + Tip amount
= 41.32 + 6.189
= $47.509
Thus,
Original price: $41.32
Tip: 15% = %6.189
Total amount = = Original price + Tip amount
The total amount is $47.509

An ant stands atop a grassy hill looking at a castle. A horizontal bridge 20 feet long crosses the gap, forming a right angle with the castle wall. The hill slopes down to a moat (water) that is 10 feet wide. The moat has 0 alligators because this is a math problem, not Louisiana. The castle is 38 feet tall, measuring from moat to roof.
a) Draw a sketch showing all the information you have right now.
b) The angle of elevation from the ant to the castle roof is 54.5°. Find the height of the castle above the bridge to the nearest foot (whole number).
c) What is the distance of the vertical drop from the bridge into the moat?
d) Find the angle between the hillside and the underside of the bridge. You may assume that the hill's slope is perfectly straight.

What is the value of 95 - 10 + +2(141 - 7)?
Answer:
353
Step-by-step explanation:
95 - 10 + 2(141 - 7)
following PEMDAS we will do parenthesis first
95 - 10 + 2(134)
multiplication is next
95 - 10 + 268
addition and subtraction are interchangeable when using PEMDAS but you do whatever comes first. since it's subtraction first in this equation we will do 95 - 10.
85 + 268
now we are left with addition
85 + 268 = 353

Determine if the side lengths listed create a right triangle, acute triangle, obtuse triangle, or do not make a triangle. 3, 9, 10 Determina si las longitudes de los lados enumeradas crean un triángulo rectángulo, un triángulo agudo, un triángulo obtuso o no forman un triángulo. 3, 9, 10 * 1 point right acute obtuse not a triangle
Answer:
Obtuse triangle
Step-by-step explanation:
Given the side lengths :
3, 9, 10
Let :
a = 3 ; b = 9 ; c = 10 (longest side)
If a² + b² = c² (right angle)
If a² + b² > c² (acute angle)
If a² + b² < c² (obtuse angle)
a² + b²
3² + 9²
9 + 81 = 90
c² = 10² = 100
90 < 100
Hence,
a² + b² < c² (then we have an obtuse triangle)
