In total there are 32 keys.
There 24 silver and copper keys so the probability of one being drawn is 24/32
Now just simplify
24/32 = 12/16 = 6/8 = 3/4
Answer:
Step-by-step explanation: add the equations
2x² = 30
x² = 15
y² = 12 - 15
= -3
x4 -y4 = 15² - (-3)²
= 216
37 because theres 32 plus 5 which makes it 37
Answer:
y = 2x -3
Step-by-step explanation:
y = 2x + b
plug the point in to the formula and solve for b
17 = 2 x 10 + b
b = -3
Use this to write the formula y = mx + b
m is slope
