Answer: you didnt post graphs to look at
Step-by-step explanation:
Answer:
you could divide
Step-by-step explanation:
Answer:
x = 3, y = - 2
Step-by-step explanation:
By substitution method,
4x + y = 10 -------> equation 1.
7x + 2y = 17 -------> equation 2.
From equation 1,
y = 10 - 4x ------> equation 3.
Substitute equation 3 in 2,
7x + 2 ( 10 - 4x ) = 17
7x + 20 - 8x = 17
7x - 8x = 17 - 20
- x = - 3
x = 3
Substitute x = 3 in equation 1,
4 ( 3 ) + y = 10
12 + y = 10
y = 10 - 12
y = - 2
Hence,
x = 3
y = - 2
The formula for the amount A in an account with principal P and interest rate r compounded annually for t years is
... A(t) = P(1+r)^t
You want to find A when P=400, r=0.05, and t=3. Substituting those values gives you
... A(3) = 400·(1 +0.05)³
The appropriate choice is
... A. A(3) = 400·(1 +0.05)³
Ok don't panic!!!
First you look and see that 3 dozen is 36 and you need 720 cookies so that every person gets 2 cookies. so you first need to multiply 36 by 10 to get 360 then multiply that by 2.
So, in conclusion multipy each of the ingredients by 20! :)
17/16 x 20 = 340/16 of butter
5/8 x 20 = 100/8 of white sugar
7/4 x 20 = 140/4 of vanilla extract
15/8 x 20 = 300/8 of flour
5/6 x 20 = 100/6 of almonds
7/12 x 20 = 140/12 of confectioner's sugar
