x=10
Step-by-step explanation:
7x - 5=65
+5 +5 so the 5's cancel so add 5 to 65
7x =70 because you add 5 to 65 to get 70
7x 7
7 x cancels out so you answer will be
x=10
Answer:
A = (Z-CD - EFG)/B
Step-by-step explanation:
AB + CD + EFG = Z.
Subtract CD and EFG from each side
AB + CD + EFG-CD -EFG = Z-CD - EFG
AB = Z-CD - EFG
Divide each side by B
AB /B = (Z-CD - EFG)/B
A = (Z-CD - EFG)/B
Answer:
45 because an acute angle is 45 degrees
Answer:
A
Step-by-step explanation:
X values cannot repeat in a function, 3 is used as an X value twice in A, and therefore cannot be a function.
If this is graphed, you can use the vertical line test, if a vertical line on any point goes through other points, it is not a function.
In this case, just check if X repeats.
