Answer:
The cost for each pound of chocolate chips is $2.75 and the cost for each pound of walnuts is $3.75.
Step-by-step explanation:
9x+7y=51
3x+5y=27
----------------
9x+7y=51
-3(3x+5y)=-3(27)
-------------------------
9x+7y=51
-9x-15y=-81
-------------------
-8y=-30
8y=30
y=30/8
simplify,
y=15/4
9x+7(15/4)=51
9x+105/4=51
9x=51-105/4
9x=(204-105)/4
9x=99/4
x=(99/4)/9
x=(99/4)(1/9)=99/36
simplify
x=2.75
So the cost for each pound of chocolate chips is $2.75 and the cost for each pound of walnuts is $3.75.

Answer:
Table:
0,200
4, 262
8,344
12, 450
Population after 12 years is 450 deer
Initial population is 200 deer.
Step-by-step explanation:
You take the x in the table and plug it in as an exponent so you will need a calculator or multiple the 1.07 by that many times so 1.07 12 times multipled by itself. and the initial is 0 years so anything to the exponent of 0 is 1 so that show i got 200 for the x=0
Answer:
B)Only one graph intersects the y-axis above y=0
Step-by-step explanation:
Both functions are in y=mx+b. The y-intercept is b.
f(x) has the y-intercept 3. It intersects above y=0.
g(x) has the y-intercept -4. It intersects below y=0.
This means B is correct.
