Equation 1: x² + y = 7
Equation 2: 3x + 7 = 9
Use Equation 2 to solve for "x" and plug in "x" into Equation 1 to solve for "y".
3x + 7 = 9
3x = 2
x = 
*********************************
x² + y = 7
()² + y = 7
+ y = 7
y = 7 -
y = 
-
y = 
Answer: (, )
Answer:
Decrease
Step-by-step explanation:
160/40 = 4 units/hour

The answer of the question is 'b'.
Answer:
A. True
Step-by-step explanation:
Even numbers are divisible by 2 with no remainder. 13/2 = 6.5 so yes.
Percent error is calculated as
.
The approximation in this case is 3.14, and the theoretical or actual value is pi.
Using the formula, the percent error will be:
= -0.0507%
