No; since there is the added possibility of field goals, the number of points is not proportional to touchdowns. If only touchdowns were possible, then yes, it would be proportional.
Answer:
2.81 and 0.3 are two decimals that give a product of 8.43 which is close to 8.4
Step-by-step explanation:
let consider a decimal number 0.3
now consider another decimal number 2.81
now if we multiply these two numbers then we get 8.43 which is also a decimal number and it is close to 8.4.
Given:
1st purchase: <span>38 bed sheets and 61 towels for $791.50
2nd purchase: </span><span>54 bed sheets and 50 towels for $923
Let x = bed sheets ; y = towels
38x + 61y = 791.50
54x + 50y = 923.00
Find the value of y:
50y = 923.00 - 54x
y = 923/50 - 54x/50
y = 18.46 - 1.08x
Substitute y to find the value of x.
38x + 61y = 791.50
38x + 61(18.46 - 1.08x) = 791.50
38x + 1126.06 - 65.88x = 791.50
38x - 65.88x = 791.50 - 1126.06
- 27.88x = -334.56
x = -334.56/ -27.88
x = 12
Find the value of y using the value of x.
y = 18.46 - (1.08x)
y = 18.46 - (1.08*12)
y = 18.46 - 12.96
y = 5.5
Each bed sheet costs $12 and each towel costs $5.50
To check:
</span>38x + 61y = 791.50
38(12) + 61(5.5) = 791.50
456 + 335.5 = 791.50
791.50 = 791.50
<span>54x + 50y = 923.00</span>
54(12) + 50(5.5) = 923
648 + 275 = 923
923 = 923
Answer:
<u>(3, -1)</u>
Step-by-step explanation:
<u>Given</u>
<u>Subbing the value of y</u>
- 4x + 5(3x - 10) = 7
- 4x + 15x - 50 = 7
- 19x = 57
- x = 3
- y = 3(3) - 10
- y = 9 - 10
- y = -1
- Solution is <u>(3, -1)</u>
The answer is D because the answers are put into vertex form and all you have to do is look at your (h,k) values
