Answer:
No Solution
Step-by-step explanation:
If two lines have the same slope and different y-intercepts, that means there is no solution. If the y-intercept and the slope are the same, it will have infinite solutions... So because these have the same slope, but different y-intercepts, they won't have any solution.
Answer:
x = ±sqrt(y-11)
Step-by-step explanation:
y = x^2 +11
Subtract 11 from each side
y -11 = x^2 +11-11
y-11 = x^2
Take the square root of each side
±sqrt(y-11) = sqrt(x^2)
±sqrt(y-11) = x
You would just do 4 x 7, which means there are 28 combinations.

I hope this this is what you need ..
Let's assume
number of small notebooks =x
number of large notebooks =y
we are given
total number of notebooks =31
so, we get

now, we can solve for y

we have
Small notebooks cost $3.50 and large notebooks cost $5.00
she has $134 to spend
so, we get

now, we can plug y





now, we can find y


so,
number of small notebooks is 14
number of large notebooks is 17.............Answer
