Answer:
y = -1/2c - 8
Step-by-step explanation:
2c - y = 6
2c -6 = y
Slope: 2. Slope of the perpendicular line: -1/2
Point (-4,-6)
y-intercept = -6 - (-1/2)(-4)
b = -6 -2 = -8
Answer:
4.5 pounds. 1 pounds is = to 16 ounces. 16 x 4.5 is 72 ounces so 4.5 pounds is 1 ounce bigger.
7B+5Y=487B+1Y=40Subtracting Eqn 2 from 1 we get 4Y=8so Y = $2 and X=$38/7
X*2 +5 =41
Subtract 5 from both sides
X*2=36
Square root of 36 is 6
X=6
Solve
6*2+5 =41
This’s correct!
Answer:
£0.465. It is a better value.
Step-by-step explanation:
If a pack of 6 batteries costs £2.79, price of a battery can be calculated as shown;
6batteries = £2.79
1 battery = x
x = cost of a battery
6x = £2.79
x = £2.79/6
x = £0.465
Price per battery will be £0.465. This price is a better value since the price is lesser than the cost of the 6batteries (£2.79) in a pack.
