Answer: a) 
b) Cost of a macadamia nut chip cookie is $33.93 and the cost of triple chocolate cookie. is $3.77
c) Elimination method because it enables us to eliminate one of the variables.
Step-by-step explanation:
Let x be the cost of macadamia nut chip cookie and y be the cost of triple chocolate cookie.
Then according to the question we have the following equations:-
Multiplying 5 on both sides of the equation (2), we get
...............(3)
By using elimination method, subtract equation (1) from (3) we get
Substitute the value of y in (2), we get
Answer:
Step-by-step explanation:
A. $0.08
Step-by-step explanation:
I would find out the total price of potatoes for each person:
Sofia: $0.85 x 3.8lb = $3.23
Flynn: $0.75 x 4.2lb = $3.15
To get the final answer, I would subtract to find the difference between the two prices.
$3.23 - $3.15 = $0.08
<span>f(x)= 3x-8
x = -2, </span><span>f(x)= 3(-2) -8 = -6 - 8 = -14
</span>x = -1, f(x)= 3(-1) -8 = -3 - 8 = -11
x = 0, f(x)= 3(0) -8 = 0 - 8 = -8
x = 1, f(x)= 3(1) -8 = 3 - 8 = -5
x = 2, f(x)= 3(2) -8 = 6 - 8 = -2
Domain <span> {-2, -1, 0, 1, 2}
</span>Range: <span> {-14, -11, -8, -5, -2}
</span>
answer
Range: {-14, -11, -8, -5, -2}
<span>The answer will be (x - 3)^2</span>
This is a geometric sequence of the form:
a(n)=(x+3)(-2x)^(n-1) because each term is -2x times the previous term...so
a(8)=(x+3)(-128x^7)
a(8)=-128x^8-384x^7
