Answer:
y = -2x + 8
Step-by-step explanation:
y = mx + b
-8 = -2(8) + b
-8 = -16 + b
8 = b
y = -2x + 8
$19.99 x 4 = $79.96
$22.50 x 6 = $135
$19.99 x 6 = $119.94
$22.50 x 4 = $90
The best answer to this choice is 4 dvds for $19.99. why?, because if it was 6 or 4 dvds for $19.99 the price would be more inexpensive then the price for $22.50, because if it was 22.50 x 4 or 6 dvds the price would be more expensive.
Answer:
Apprentice = $800
Journeyman = $1600
carpenter = $4000
Step-by-step explanation:
Let the apprentice earns X dollars.
Then ,
Journeyman will make 200% of apprentice's earning which is 2X.
Also,
Carpenter makes 250% of the earning that journeyman makes.
Which is 2.5(2X) = 5X
Their total earning should come to $6400.
Thus,
X + 2X + 5X = 6400
8X = 6400.
X = $800
So,
Earning of apprentice = X = $800
Earning of Journeyman = 2X = $1600
Earning of carpenter = 5X = $4000
Answer:
do the reverse of pie r squared
Step-by-step explanation:
14 of the machine that cost $150 was sold and 8 of the machine that cost $225 was sold.
To solve this problem, we would write a system of linear equations.
- Let x represent the machine that cost $150
- Let y represent the machine that cost $225
We can proceed to write our equations now.
From equation 1
<h3>The Value of Y</h3>
put equation (iii) into (ii)
<h3>The Value of X</h3>
Since we know the number of y, we can simply substitute it into equation (i) and solve.
From the calculations above, 14 of the machine that cost $150 was sold and 8 of the machine that cost $255 was sold.
