slope = 4/1 = 4
b = y - mx
b = 4 - 4(1)
b = 0
so equation
y = 4x
answer
last one y = 4x
Answer: 25
Step-by-step explanation:
Answer:
x = -
Step-by-step explanation:
Given
49 + 2x = 6x + 52 ( subtract 6x from both sides )
49 - 4x = 52 ( subtract 49 from both sides )
- 4x = 3 ( divide both sides by - 4 )
x = = - = - 0.75
<span>Let number of experienced crew = X
Let number of novice crew = Y
Number of rooms experienced crew can prep = 6X
Number of rooms experienced crew can paint = 2X
Number of rooms novice crew can prep = 2Y
Number of rooms novice crew can paint = 2Y
Number of rooms to be prepped per week = 12
Number of rooms to be painted per week = 8
So, we have
Equation 1 - For Prepping
6X + 2Y = 12
Equation 2 - For Painting
2X + 2Y = 8 or 2Y = 8 - 2X
Replacing the value of 2Y from equation 2 in equation 1, we have
6X + (8 - 2X) = 12
Simplifying the equation we get
4X + 8 = 12
4X = 12 -8
4X = 4
X = 4/4
X = 1
Replacing the value of X in Equation 1, we get
6 * 1 + 2Y = 12
2Y = 12 - 6
2Y = 6
Y = 6/2
Y = 3
Total cost per week = 1 * 1000 + 3 * 750 = 1000 + 2250 = 3250
So, to optimize costs, John would need 1 experienced crew and 3 novice crews at a total cost of $3250 per week.</span>
