Gradient = 

This means the gradient is 4x.
The y intercept is where the line crosses the y axis. We can see this is at -3.
<h2>
Rule: <u>y = 4x -3</u></h2>
Substitute your values to check if it's right.
y = 4x -3
5 = 4(2) - 3
5 = 8 - 3
5 = 5
1 = 4(1) - 3
1 = 4 - 3
1 = 1
Answer: Malik's total profit is $213
Step-by-step explanation:
2 * 45 = 90
2 * 65 = 130
130 - 90 = 40
3 * 85 = 255
3 * 126 = 378
378 - 255 = 123
5 * 5 = 25
5 * 15 = 75
75 - 15 = 50
50 + 40 + 123 = 213
44 chicken and 28 rabbits
Given:
chicken head + rabbit head = 72 heads
chicken feet + rabbit feet = 200 feet
c + r = 72
2c + 4r = 200
find the value of c using the 1st equation:
c = 72 - r
substitute c by its value in the 2nd equation:
2c + 4r = 200
2(72-r) + 4r = 200
144 - 2r + 4r = 200
2r = 200 - 144
2r = 56
r = 56/2
r = 28
c = 72 - r
c = 72 - 28
c = 44
c = 44 ; r = 28
To check:
2c + 4r = 200
2(44) + 4(28) = 200
88 + 112 = 200
200 = 200
The group with need to fill the spoon a total of 3 times this is because 1/8+1/8+1/8=3/8
#22: 10.2 gallons for $2.59 each = 10.2 x 2.59, which rounded is $26.42.
#23: 12 pieces that are 6.45 in wide each = 12 x 6.45, which is 77.4 in.
#25: Aaron started with $38.
$22.47 + $8.53 + $6.50 is $37.50.
38.00 - 37.50 is .50 or 50 cents.
Hope that helps!
