Answer:
x = 49/8, y = -11/2
Step-by-step explanation:
look at the attached picture.
Answer:
If the expression is:
-3x + 12 = -3x + 12, infinite solutions
If the expression is:
-3x + 12 = -3x - 12, no solutions
Step-by-step explanation:
Step 1: Distribute
-3x + 12 = 3x = 12
If both lines have the same slope and same y-int, they are the same line and therefore have infinite solutions.
If both lines have the same slope but different y-int, then they are parallel and therefore have no solutions.
Answer:
m = 7 - 3n
Step-by-step explanation:
m + 3n = 7
subtract 3n from both sides
m + 3n = 7
- 3n -3n
m = 7 - 3n
Answer:
50 miles per hour
Step-by-step explanation:
Here,
Time= 8 hours
Distance=400 miles
The speed is calculated by dividing the distance by time.
So,
Average Speed=Distance/Time
= 400/5
=50 miles per hour
Answer:
When you have two sets of data, one that represents an independent variable (X) and another that represents a dependent variable (Y) (it is a response of the first variable). A diagram called scatterplot can be generated to present the ordered pairs (X, Y) in the Cartesian plane to see how the two variables are related.
In this case the independent variable (X) is the age variable of the calf and the dependent variable (Y) is the weight of the calf.
The diagram can be seen in the attached file.
