7/5 * 5/7y = 7/5 * 6
y = 42/5.
The multiplication property of equality is used.
Answer:
(x - 4)
Step-by-step explanation:
Given x = a is a root then (x - a) is the corresponding factor
Given x = 4 is a root, then
(x - 4) ← is the corresponding factor
Note if x = - 4 is a root , then
(x - (- 4)), that is (x + 4) is the corresponding factor
Answer:
-2
Step-by-step explanation:
In a linear regression model we have the equation 
that relates 
and 
, where 
is the estimator of the slope and 
is the estimator of the Y-intercept. The coefficients and can be estimated with the equations:
. Thus,
Answer:
no
Step-by-step explanation:
first simplify or solve the original expression ( 3(x + 11/2)-3 )
1. Parenthesis go first so do the 11/2 = 5.5 (x+5.5)
2. Distribute the 3 to the parenthesis (3x + 16.5)
3. subtract 3 from the expression (3x + 13.5)
Compare new equation with 3x + 11/2. Are they the same? (3x+13.5 vs. 3x + 11/2)
They are not the same thing.
Answer:
0
Step-by-step explanation:
any numbers multiply by zero always equals to zero
