7 weight exactly the same, therefore the 8th golf ball doesnt weigh the same as the 7. so the 8th ball is slightly lighter
The coordinate for A, B, C, and D: (Current coordinates)
A: (-1, 4)
B: (-5, 8)
C: (-5, 4)
D: (-4, 2)
Once we reflect acorss the y-axis the coordinates become:
A': (1, 4)
B': (5, 8)
C': (5, 4)
D': (4, 2)
In this situation the coordinates just become positive.
I hope this helps!
The solution of the system of equations is (-3 , -2)
Step-by-step explanation:
Steps for Using Linear Combinations Method)
- Arrange the equations with like terms in columns
- Analyze the coefficients of x or y
- Add the equations and solve for the remaining variable
- Substitute the value into either equation and solve
∵ 3 x - 8 y = 7 ⇒ (1)
∵ x + 2 y = -7 ⇒ (2)
- Multiply equation (2) by 4 to make the coefficients of y are equal in
magnitude and different in sign
∴ 4 x + 8 y = -28 ⇒ (3)
Add equations (1) and (3)
∵ 3 x - 8 y = 7 ⇒ (1)
∵ 4 x + 8 y = -28 ⇒ (3)
∴ 7 x = -21
- Divide both sides by 7
∴ x = -3
Substitute the value of x in equation (2) to find y
∵ x + 2 y = -7 ⇒ (2)
∵ x = -3
∴ -3 + 2 y = -7
- Add 3 to both sides
∴ 2 y = -4
- Divide both sides by 2
∴ y = -2
The solution of the system of equations is (-3 , -2)

Step-by-step explanation: You just draw a line that is long enough for your question its that simple
Answer:
y = 2
Step-by-step explanation:
For the exponential function in the form
y = a
Use ordered pairs from the table to find a and b
Using (0, 2 ), then
2 = a
( = 1 ) , thus
a = 2, so
y = 2
Using (1, 6 ) , then
6 = 2b ( divide both sides by 2 )
b = 3
Thus the exponential function is
y = 2
