Answer:
Step-by-step explanation:
2V - 66
This is just an expression. It is not an equation and it cannot be solved. You are just being asked to set up something that could be used later on.
Answer:
x=18, m∠1=140, m∠2=40
Step-by-step explanation:
m∠1 and m∠2 will equal up to 180
7x+14+2x+4=180
Combine like-terms
9x+18=180
Subtract 18 from both sides.
9x=162
Divide both sides by 9
x=18
Then plug in 18 for x in the angle measures
7(18)+14=140
2(18)+4=40
Answer:
These numbers are - parameters.
Step-by-step explanation:
A study of all the students at a small college showed a mean age of 20.9 and a standard deviation of 2.9 years.
These numbers are - parameters.
These numbers are parameters as they are for all the students, and merely not a sample.
Use the figure above as a reference. Identify the vertices of the rectangle before translation, the vertices are (-4,5), (1, 5), (-4,-2), and (1, -2). After translation of 6 units to the left, only the x-coordinates of the vertices are affected. Since the translation is to the left, subtract 6 from the x values of the vertices. Therefore, the vertices after translation are: (-10, 5), (-5, 5); (-10, -2) and (-5, -2).
The ordered pair not in the new set of vertices is (2, -2).
Answer:
y=4x
Step-by-step explanation:
Given : x represent the number of television show episodes that are taped in each seasons
To Find : write an expression for the number of episodes taped in 4 seasons
Solution:
Let number of episodes taped in 4 seasons be y
Number of the episodes taped in 1 season = x
So, number of episodes taped in 4 seasons :
y= 4x
Hence the required expression for the numder of episodes taped in 4 seasons :y= 4x
