You can use a simultaneous equation - x + 7y=24 minus x-9y= -24 you end up with 16y = 48
Divide 48 by 16 and you get 3 is equal to y. Now put three into an equation eg, x + 21 = 24 it is now obvious that x = 3 as well as y = 3
Answer:
3/4
Step-by-step explanation:
f(x) = 3 *2^x
Let x= -2
f(-2) = 3 *2^(-2)
= 3 * 1/2^2
= 3 /4
Answer:
No
Step-by-step explanation:
Lets simplify both expressions:
We will start with Gloria's first expression:
Apply distributive property:
Combine like terms, we are then left with:
Now lets simplify the second expression
Apply distributive property
Rearrange:
Now we can see that the two equations are not equal, as the first is 12 greater than the second. Another way we could have tested this was plugging in a value for x and then solving.
Answer:
), M-1,0), and N(-5, -2): (x, y) → (x, y – 5) K'( L'(_. M' ( N' (.
