2x-3y=9
Find slope-
x-intercept-
y-intercept-
Answers
get the equation in slope intercept form
2x-3y=9
subtract 2x from each side
-3y = -2x +9
divide by -3
y = 2/3 x -3
slope = 2/3
y intercept = -3
x intercept set y=0 and solve
0 = 2/3 x -3
add 3 to each side
3 = 2/3 x
multiply each side by 3/2
9/2 = x
the x intercept is 9/2 or 4 1/2
y=(2x-9)/3
y=(2/3)x-3
slope(m)=2/3
finding x-intercept..
if y=0
2x-3(0)=9
x=9/2
finding y-intercept..
if x=0
2(0)-3y=9
y=-3

It seems to me c could be any number besides 2,12,-1 or 0
why?
a function is defined by each x value having a single y value
if an x value has two numbers such as (0,1) (0,2) than it is not a function.
the vertical line test is great for seeing if something is a function becasue it determines if each x value has one y value.

Answer:
C
Step-by-step explanation:
the answer would be C, or y = 0.125x + 625 because in the problem, it says that the store would require an upfront payment of $25 PLUS $50 a month, then 12.5% interest at the end of the year, then it asks what the equation would be after 12 months. SO we know that is a year (since there are 12 months in a year) so we would multiply that by number by the $50 we would have to pay a month which would look like this: 12 months x $50 a month = $600. then, we would add the initial $25 dollars, which would give us a total of $625 which we'd add to the equation. next, if we look at 12.5% and then at our answer choices, we can see that they converted the percent to a decimal. 12.5% is equivalent to 0.125, therefore our final answer is C!
i hope this helps :D

switch all x wih y and y with x
solve for y
replace y with h(x)
f(x)=5/3x-2/7
y=5/3x-2/7
x=5/3y-2/7
x+2/7=5/3y
[3(x+2/7)]/5=y
(3x+6/7)/5=y
(21x+6)/35=y
(21x+6)/35=h(x)
h(x)=(21x+6)/35
last option is correct

Final answer:
The unit rate of the copy machine expressed in terms of copies per second is found by calculating the ratio 45 copies/25 seconds, which equals 1.8 copies/second.
Explanation:
To find the unit rate of copies per second, we need to divide the total number of copies by the total time taken. In other words, we have to find out how many copies are made in one second. Here, the copy machine makes 45 copies in 25 seconds.
To calculate the unit rate, we use the formula Unit Rate = Total Quantity / Total Time. Substituting the given numbers into the formula, we get:
Unit Rate = 45 copies / 25 seconds = 1.8 copies/second.
This means the copier's unit rate is 1.8 copies per second.
