Answer:
Equivalent systems of equations review
Step-by-step explanation:
We're given two systems of equations and asked if they're equivalent.
x + 4y = 8 (1)
4x + y = 2 (2)
Interestingly, if we sum the equations in System A, we get:
Replacing the first equation in System A with this new equation, we get a system that's equivalent to System A:
This is System B, which means that System A is equivalent to System B.
Answer:
d-2 and d cannot = 8
Step-by-step explanation:
d^2 -10d+16
-----------------------
d-8
Factor the numerator
( d-8)(d-2)
-------------------
d-8
The undefined values occur when the denominator is equal to zero
d-8 = 0
d= 8
This means d cannot equal 8
Now cancel like terms in the equation ( d-8)
This yields d-2
Answer:
Hi there!
To find an expression equal to 5(h+9), we can distribute the 5 into the equation.

I do <u>not agree</u> that passing the state math and reading tests will be a predictor of a student's success in college.
<h3>What are the factors that determine a student's success
in college?</h3>
The factors that determine a student's success in college include the following:
- Students' attitudes to learning
- Teachers' attitudes to sharing knowledge
- Teaching methods for imparting knowledge
- Classroom learning environment
- Student's belief in gender stereotypes
- Parental factors.
<h3>Question Completion:</h3>
Do you agree with the board? Mention the factors that determine a student's success in college.
Thus, it is not necessarily true that passing the state math and reading tests will be a predictor of a student's success in college.
