Answer:
y = (4/3)x - 50
Step-by-step explanation:
Step 1 :
Identify the independent and dependent variables.
The independent variable (x) is the square footage of floor space.
The dependent variable (y) is the monthly rent.
Step 2 :
Write the information given in the problem as ordered pairs.
The rent for 600 square feet of floor space is $750 :
(600, 750)
The rent for 900 square feet of floor space is $1150 :
(900, 1150)
Step 3 :
Find the slope.
m = (y₂ - y₁) / (x₂ - x₁)
Substitute (600, 750) for (x₁, y₁) and (900, 1150) for (x₂, y₂).
m = (1150 - 750) / (900 - 600)
m = 400 / 300
m = 4/3
Step 4 :
Find the y-intercept.
Use the slope 4/3 and one of the ordered pairs (600, 750).
Slope-intercept form :
y = mx + b
Plug m = 4/3, x = 600 and y = 750.
750 = (4/3)(600) + b
750 = (4)(200) + b
750 = 800 + b
-50 = b
Step 5 :
Substitute the slope and y-intercept.
Slope-intercept form
y = mx + b
Plug m = 4/3 and b = -50
y = (4/3)x + (-50)
y = (4/3)x - 50
That's such a broad question, and super subjective. I'd probably say that you learn math effectively from a good teacher or tutor, or if you're an individual learner, perhaps a textbook or any kind of online resource.
Answer:
w = weight of Adrian's cat
c = weight of Lauren's cat
c = 3 + w/2
given: c=10
10 = 3 + w/2
Solve to get 'w': 20=6+w; w=14 pounds
Step-by-step explanation:
Answer:
90$
Step-by-step explanation:
yeah he needs 90$ and he already has 54, so he only needs 36 left
The system of equations that represent the matrix is c
