Answer:
y = - x + 4
Step-by-step explanation:
The first step is to find the slope-intercept form, which is:
y=x-6.
Then, y=x+6
y=-x+4 should be the answer since it passes through the point (-1, 5)
2 apples 3-1=2 because if you have 3 apples and tom takes 1 do the math 1-3 you're answer is 2
The relation is <em>not a function</em> if any x-value is repeated.
Assuming you have
(x, y) = (3, 10), (__, 20)
if x = 3, the relation is not a function.
The main idea here is to "translate" the words into maths.
First we need to identify the unknowns and label these.
We need to know the number if dimes and the number of quarters. So lets say
x: number of dimes
y: number of quarters
Now lets write equations from the written problem.
We know that there are 36 coind total, thus:
x + y = 36
We also know that the coins total 5.85 dollars, but it is better to count in cents, that is 585 cents.
x are the number of dimes, their value is x*10
y are quarters with value of y*25
thus:
10x+25y=585
We have two equations and two unknowns now, that needs to be solved to get the answer.
x + y = 36
10x+25y=585
