Answer: The Jolene's unit rate in dollars per pound of grain is 0.25.
Explanation:
It is given that the Jolene is making a line graph that represents the price of grain and the number of pound purchase.
The number of pounds are shown on x-axis and the price in dollar are shown on y-axis.
The cost of 1 pound is 0.25, therefore the point (1,0.25) lies on the line.
The cost of 4 pound is 1, therefore the point (4,1) lies on the line.
The unit rate in dollars per pound of grain is the the slope of the line.
The slope of a line is,
Therefore, Jolene's unit rate in dollars per pound of grain is 0.25.
I’d assume the answer would be z= s^2. Because the value of s squared determines what value z will be (that’s why it varies based on s’s value)
Answer:
b=-3
Step-by-step explanation:
If the expression simplifies to bx that means the terms and the constant terms must be cancel out.
Simplify it first.
We know –4 + 4 will cancel out. If we simplify this expression to only an x term, then the terms should be cancelled. Therefore, we say that 4ax^2 – x^2 = 0.
If we put a = ¼, then we can find the value of b:
if the expression is equivalent to bx
Therefore, b = –3.
