Simplify:
7x+3=7x-3
Now 7x goes away and you get 3=-3, which cannot be true, so there is no solution
Top row is x= 10, x^2 =100, x^3 = 1000
Bottom row is 5, 25, 125
The answer is
A. No, because 1 x-value corresponds to 2 different y-values
How much after subtraction
Answer:
cosR = 
Step-by-step explanation:
assuming the right triangle has ∠ Q = 90° with legs 5 and 12
then this is a 5- 12- 13 right triangle with hypotenuse PR = 13 cm
then
cosR =
=
=
