Step-by-step explanation:
Given:-
- The oranges produced last year, x = 36
- The oranges produced this year, y < 10
Find:-
What are the possible values for how many fewer oranges were produced from the tree this year
Solution:-
- The possible values for how many fewer oranges were produced this year relative to last can be determined by solving an inequality that signifies a difference (d) between last year and this year production as follows:
d = x - y
d = 36 - (<10)
- To remove the inequality from Right hand side we we can shift it to left hand side by inverting the inequality sig, since last production is exactly known we have:
d≥36 - 10
d≥ 26
- So the number of oranges produced are at least 26 less than last year and lower bound would be if there is no orange produced this year. Hence, the range is:
d : [ 0 , 26 ]
Answer :A)-2
Step-by-step explanation: If you multiply B; x + 9y =10 by -2 you will have -2 x+ -18y= -20. Then when you add B with a 2x + 8y = 5
-2x +-18y=-20
=0 +-10y=-15
We need to use the formula for simple interest which is
I= prt
Where I is the amount of money you earned or pay in interest
p is the principal, the amount you deposited or borrowed
r is the interest rate expressed as a decimal
t is time in terms of years
In this problem, I= 1,680
p= 3000
t= 8
'. r is what we are looking for.
Substituting the numbers into the simple interest formula, we get
I=. p r t
1,680=(3000)(r)(8). Multiplying
1,680= 24,000r Divide both sides by 24,000
0.07= r
So, the percentage is (0.07)(100)= 7%...
Hey there!
A function is a relation to numbers in which an input value as a specific output value.
a) Is a function. All x values go to specific y values. For domain, look at the x values. You go from 2 to 8. So, 2≤x≤8 (we can assume the line just goes this long since we are not given anymore information) For the range, we have the same thing. It goes from 5 to 8. 5≤y≤8
b) Is not a function. 1 cannot go to two y-values.
c) Is not a function. Does not pass vertical line test.
d) Is a function. Passes the vertical line test. For the domain on this one, it would be infinite, which you could represent as (-∞,∞) It is infinite because the line as two arrows that continue forever. For the range, it would be anything greater than 2. y≥2 or 2≤y
The question stated you only needed to find the domain and range for the functions, so you would just do it for a) and d).
I hope this helps!
