Answer:
x = 4 (ONE solution)
Step-by-step explanation:
This is a first order linear equation, so we can expect 1 solution.
Multiplying out the left side, we get:
8x - 24 = 7x - 20, which simplifies to:
x = 4 (ONE solution)
Answer:
ok
Step-by-step explanation:
Answer:
Given that Angelo spends the same amount every day from the amount in
the lunch card, the function of the amount remaining is a linear function.
The constant rate of change of the function is; -5.25
The two ordered pairs used to find the constant rate of change are; (1, 44.75) and (2, 39.5)
Reasons:
The amount Angelo's mother put on the lunch card = $50
A possible table of values to the question is presented as follows;
Required:
The constant rate of the function that gives the amount remaining from the
amount Angelo's mother put on his lunch card.
Solution:
The two ordered pairs that can be used to find the slope or constant rate of change are;
(x₁, y₁) = (1, 44.75), and (x₂, y₂) = (2, 39.5)
With the above two ordered pairs, we have the constant rate of change of the function given as follows;
The constant rate of change for the function that gives the amount remaining in the lunch card is; -5.25
Here, Series: 750, ............... 1350
It's an A.P. where, a = 750 a(11) = 1350
We know, a(n) = a + (n - 1)d
1350 = 750 + (11 - 1)d
1350 - 750 = 10d
600/10 = d
d = 60
In short, Rate of change would be; $60 per year.
B.) y-y1 = m(x - x1)
y - 750 = 60(x - 1)
y - 750 = 60x - 60
y = 60x + 690
In short, Your Equation would be: 60x + 690
Hope this helps!
