4≤x/2.1
To Solve
Multiply by 2.1
8.4≤x
Step-by-step explanation:
when multiplied together, the gradients of the 2 graphs should equal -1 (of they are perpendicular).
x-7y=4
-7y= -x + 4
y= -1/7 x + 4/7
21x+ 3y=11
3y=-21x+11
y=-21/3 x + 11/3
-21/3 * -1/7 = 1
when multipled together, the 2 gradients dont equal -1 therefore they are not perpendicular
unless I've made a mistake with the signs at some point haha
The conclusion is that both gym charge the same, because the identity 75 = 75 means that the two equations are equivalent (the same).
It would be $75.
Becuase, $15 divided by 2 years equals $7.50 a year.
Therefore, $7.50 X The 10 years would be $75.
Hope that helped.
