So right of the bat the equation we know from what's given is y = 2x (+b)
we gotta find out what b is
so we plug the coordinate in
3=8+b.
b=-5
so we put all the pieces back together to get
y = 2x - 5
<h3><u>The system of linear equations that represents the situation is:</u></h3>
a + b = 28
16a + 10b = 400
<h3><u>20 scented candles and 8 unscented candles were sold</u></h3>
<em><u>Solution:</u></em>
Let "a" be the number of scented candles sold
Let "b" be the number of unscented candles sold
From given,
Cost of 1 scented candles = $ 16
Cost of 1 unscented candles = $ 10
<em><u>The shop sells 28 candles today</u></em>
Therefore,
a + b = 28
b = 28 - a ------- eqn 1
<em><u>The shop sells 28 candles today and makes $400</u></em>
Therefore,
number of scented candles sold x Cost of 1 scented candle + number of unscented candles sold x Cost of 1 unscented candles = 400

16a + 10b = 400 ------ eqn 2
<em><u>Substitute eqn 1 in eqn 2</u></em>
16a + 10(28 - a) = 400
16a + 280 - 10a = 400
6a = 400 - 280
6a = 120
a = 20
<em><u>Substitute a = 20 in eqn 1</u></em>
b = 28 - 20
b = 8
Thus 20 scented candles and 8 unscented candles were sold
Answer:
<h2>
The turkey needs to cook for 5 more minutes </h2>
Step-by-step explanation:
According to recipe, Amanda should cook for total of 1/2 hour which is 30 minutes. If she has been cooking for 25 minutes, the remaining time needed for the turkey to cook will be t<u>he difference between the total time and the time she has already spent in cooking.</u>

Hence, the turkey needs to cook for 5 more minutes

Step-by-step explanation:
You use collateral to decrease the risk for the bank. It can be like a car, or house. If you don't pay them back, they take the car or house.
Answer:
4v - 7w = (101 , -36)
6u -8v = (-78 , 58)
2u +v - 4w = (40 , -4)
11u + 3w = (-88 , 89).
Step-by-step explanation:
u(-5, 7) ; v(6 , -2) ; w(-11,4)
4v - 7w = (4*6+[-7]*[-11] , 4*[-2] + [-7]*4)
=(24+77 , -6 - 28)
4v - 7w = (101 , -36)
6u - 8v = (6*[-5]+[-8]*6 , 6*7+[-8]*[-2] )
= (-30-48 , 42+16)
6u -8v = (-78 , 58)
2u + v - 4w = (-10+6+44 , 14 -2 -16)
2u +v - 4w = (40 , -4)
11u + 3w = (11*[-5]+3*[-11] , 7*11 +3*4)
= (-55-33 , 77+12)
11u + 3w = (-88 , 89)
