y=2x-3
Step-by-step explanation:
y=mx+c
m=gradient=
5-(-5)/4-(-1)
=10/5
=2
c=y intercept=-3
y=2x-3
Answer:
x = $3.50; y = $2.25
Step-by-step explanation:
First, come up with your two equations where x= price of walnuts and y= price of chocolate chips: 8x + 4y = 37 and 3x + 2y = 15. Solve the first equation.
3x + 2y = 15
3x = 15 - 2y
x = (15 - 2y)/3
Plug in the answer to your second equation.
8(15 - 2y)/3 + 4y = 37
(120 - 16y)/3 + 4y = 37
120 - 16y + 12y = 111
120 - 4y = 111
-4y = -9
y = 2.25
Plug in your answer to find <em>x.</em>
3x + 2(2.25) = 15
3x + 4.5 = 15
3x = 10.5
x = 3.5
Check your equation.
1) 3(3.5) + 2(2.25) = 15
10.5 + 4.5 = 15
15 = 15
2) 8(3.5) + 4(2.25) = 37
28 + 9 = 37
37 = 37
You do

-30
5n=-30 so...
-30/5=-6
Therefore
n=-6

Answer:
D.
Step-by-step explanation:
Since we're using exponential decay, the answer would have to be less than 1.00, already eliminating A, B, and C. 1.00 - .12 = .88, which proves that D is our answer. Hope this helped! If you could, please mark brainliest if it's right.
