Answer:
y=3/2x-2
Step-by-step explanation:
gradient line 1= -2/3
perpendicular meaning gradients when multiplied should be -1
gradient line 2=3/2
<u>y</u><u>+</u><u>2</u>=3/2
x-0
y+2=3/2(x-0)
y+2=3/2x-0
A=(1,2,3)
B=(0,1,2)
A×B=(1,2,3)×(0,1,2)
A×B=((0,1),(1,1),(1,2),(0,2),(1,2),(2,2),(0,3),(1,3),(2,3))
Quarter = 0.25
Nickel = 0.05
3 Quarters = 0.25 * 3 = 0.75
6 Nickels = 0.05 * 6 = 0.30
Add to find the total amount of money they have:
0.75 + 0.30 = 1.05
They have to split it equally:
1.05 / 3
Answer: x= 5 and y= -2 or (5,-2)
7 hours
24 + 3x = 45
3x = 21
x=7
