You would now have 12 postcards now you have to buy 3 of the single set to get to 15 cards
Convert to a fraction by placing the decimal number over a power of 10 answer is 7/20
Answer:
The rate of change = 3
Initial value = 2
Step-by-step explanation:
The linear function has the form ⇒ y = mx + c
Where m is the slope or the rate of change, and c is y-intercept.
Given: A linear function passes through the point (1,5)and (7,23)
So, m = (y₂-y₁)/(x₂-x₁) = (23-5)/(7-1) = 18/6 = 3
So, y = 3x + c
By substitution with the point (1,5)
So, at x = 1 , y = 5
5 = 3*1 + c
c = 5 - 3 = 2
∴ y = 3x + 2
so, the rate of change = 3
And initial value = 2
initial value is the value at which x = 0 which is the y-intercept
Answer:
35 tons.
Step-by-step explanation:
70,000 divided by 2000 equals 35.
<span>3x – y = 18
We start by plugging in 27 for y. The goal is to isolate x by itself to solve for x.
3x - 27 = 18
Then we add 27 to both sides of the equation
3x = 45
Lastly, we divide both sides by 3 to finally isolate x by itself and solve.
x = 15</span>
