The function () = 150(1.3)
represents the number of bikes sold at Peer’s Bike store in months. The graph
represents the amount of bikes sold at Cycles R Us bike store in the same time period
Cycles R Us sold 100 bikes more than Peer's Bike store in week zero.
Peer's Bike store sold 50 bikes more than Cycles R Us bikes store.
Exponential function:An exponential function is defined by the expression,[tex]y(t)=y_0(1+r)^t[/tex]
Where, [tex]y(t)=[/tex] Final value
[tex]y_0=[/tex] Initial value
[tex]r=[/tex] rate of increase
[tex]t=[/tex] Time or duration
Given in the question,
Exponential function representing the bikes sold at Peer's Bike store,[tex]y(t)=150(1.3)^t[/tex]
At t = 0,
[tex]y(0)=150(1.3)^0[/tex]
[tex]y(0)=150[/tex]
Graph representing the function for the bikes sold at Cycles R Us bikes store,[tex]y(t)=y_0(1+r)^t[/tex]
From the graph attached,
At t = 0 , [tex]y_0=100[/tex]
Difference in the bikes sold at Peer's Bike store and Cycles R Us bikes store = [tex]150-100[/tex]
= [tex]50[/tex]
Therefore, 50 more bikes were sold at Peer's Bike shop than at Cycles R Us store.

Answer:
4:6
Step-by-step explanation:
Use elimination to solve the system of equations. Enter your answers in the boxes.
3x - 2y = 24
x + 2y = 48
X =
Hy=
v
Answer:
x = 18 , y = 15
Step-by-step explanation:
Given the 2 equations
3x - 2y = 24 → (1)
x + 2y = 48 → (2)
Adding the 2 equations term by term will eliminate the y- term
4x + 0 = 72
4x = 72 ( divide both sides by 4 )
x = 18
Substitute x = 18 into either of the 2 equations and solve for y
Substituting into (2)
18 + 2y = 48 ( subtract 18 from both sides )
2y = 30 ( divide both sides by 2 )
y = 15

John says the transformation rule (x, y) Right-arrow (x + 4, y + 7) can be used to describe the slide of the pre-image (4, 5) to the image (0, –2). What was his error?
sample response: The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5) into the rule. You get (4, 5) → (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image. Instead the rule was applied to the image. This is the source of the error.
Answer:
The transformation rule should be applied to the pre-image. The application of the rule results in the point (8, 12). The transformation rule was applied to the wrong point.

Answer:
67.9
Step-by-step explanation:
The polygon has 6 sides.
Sum if interior angles = (n-2)180
=(6-2)180
= 4 x 180
= 720
A + B + C + D + E + F = 720
x+40 + 2x-9 + 2x + 2x + x + x+78 = 720
9x + 109 = 720
9x = 720-109
9x = 611
x = 611/9
x = 67.9

Answer:

Multiply
For every 1 mm on the map there are 200 miles of actual distance (third option)
8 cm, 26.8 cm, and 58 cm (last option)
Step-by-step explanation:
Question 1:
An airplane is 180 feet long. Blake makes a scale model of the airplane at 1:60 of its actual size how long is the model?
If the model is scaled down by 1/60, then the model is 60 times smaller than the actual airplane. Set the model size as "x" and so we can write this ratio.
1 / 60 = x / 180
Cross multiply (multiply 60 and x, and 180 and 1)
60x = 180
x = 3 feet
Question 2:
To produce an enlarged or reduced measure you ____ the scale.
In order to find the measure, you multiply it by the scale factor.
Question 3:
A scale on a map is 1 mm: 200 miles
The question tells us that for every 1 mm, there are actually 200 miles. So the answer is the first option, For every 1 mm on the map there are 200 miles of actual distance.
Question 4:
What are the new dimensions if we expand the triangle below by a factor of 4.
If we multiply by the scale factor, 4, we get
2 * 4 = 8
6.7 * 4 = 26.8
14.5 * 4 = 58
Thus, the answer is 8 cm, 26.8 cm, and 58 cm (last option)

PLS HELP ME 12x - 15 = 6 - 3x
Can you pls show me the solving steps and the answer I have to type a paper on how to solve this problem help me plsss (10 points)
Answer:
x= 21/15
if you need to reduce it would be x=7/5
Step-by-step explanation:
12x-15 =6-3x
add 3x to both sides
15x- 15 = 6
now add 15 to both sides
15x = 21
lastly divide both sides by 15
x= 21/15
if you need to reduce it would be x=7/5
Answer:
x = 7/5 or 1.4
Step-by-step explanation:
12x - 15 = 6 - 3x Need to move one variable term to the other side to
+3x + 3x isolate it on one side
---------------------------
15x - 15 = 6 need to +15 to isolate the variable term
+15 +15
-----------------------
15/15x = 21/15 (simplify 21/15 = 7/5) need to divide by 15 to isolate x
------------------------
x = 7/5 or 1.4

Answer:
∠V = 33°
∠W = 90°
∠X = 57°
Step-by-step explanation:
In a right triangle, the sum of the acute angles is 90 degrees
(2x+3) + (3x+12) = 90
combine like terms
5x + 15 = 90
5x = 75
x = 15
∠V = 2x+3, x=15
2(15) + 3
30 + 3
33°
∠X = 3x+12, x=15
3(15) + 12
45 + 12
57°

Answer:
(4√2)x inches
Step-by-step explanation:
