-7x -2y= -13
-x + 2y= -11
-8x=-24
x=3
(3) - 2y= 11
-2y= 8
y= -4
(3,-4)
Answer:
a)f(o)=12
f(1)=0
f(12)=1320
c)x=1
Step-by-step explanation:
Firstly, add 2 to both sides of the equation: 
Next, multiply both sides by 5/3: 
Next, square root both sides: 
Lastly, factor out i (i = √-1) and <u>your answer will be
</u>
Right? So if you had a ten block that would represent that for a 10 so 15 minus 10 know 5 left so we would use 5 1 blocks
Answer:

Step-by-step explanation:
Since we know -7x=y we use the substitution method and plug it in the top equation.



or x=-2/3
Then plug it back in the the bottom equation

y=14/3
