Answer:
No, it is a quadratic function
Step-by-step explanation:
If you mean y=x²-1, then it is a quadratic, since we have x to the 2nd power.
If we had an equation in the form of y=mx+b, where m is the slope and b is the y intercept, it is linear.
An example of a linear function would be, y=6x-5

Write an expression equivalent to (9m3 + 5m2 - 3y 2) - (2m3+2m2) - (3m2 - y2) using the fewest number of possible terms
Answer = (9m³ + 5m² - 3y²) - (2m³+2m²) - (3m² - y²) [expand the brackets]
= 9m³ + 5m² - 3y² - 2m³- 2m²-3m² + y² [group like terms]
= 9m³- 2m³+ 5m²- 2m²- 3m²- 3y²+ y² [simplify]
= 7m³ - 2y²
John has 3-hectares farm land. He wanted that half of his farm will be transplanted by glutinous rice and the other half will be broadcasted by ordinary rice variety. How many kilos does he need to the two different rice variety?
NOTE:
100 kl/ha seeds needed if transplanting or direct seeding using drum seeder.
200 kl/ha seeds if the seeds will be broadcasted.
9514 1404 393
Answer:
150 kL glutinous rice
300 kL ordinary rice
Step-by-step explanation:
Each half of the property is 3 ha/2 = 1.5 ha.
For the transplanted glutinous rice, John needs ...
(100 kL/ha)·(1.50 ha) = 150 kL
For the broadcast ordinary rice, John needs ...
(200 kL/ha)·(1.50 ha) = 300 kL

Help! Please no links or I will report u!!
Answer:
D
Step-by-step explanation:
The range is all of the y values that make a function true. Our graph here starts at y=-2 and then goes up for infinity. This means the range is y ≥ -2. The domain is [0, ∞) because our x values start at 0 and go to infinity. This means the domain is restricted so A is not true, B is not true because the graph does not exist at x = -2.

Mary is buying tickets for a movie.
• Each adult ticket costs $9.
• Each child ticket costs $5.
• Mary spends $110 on tickets.
• Mary buys 14 total tickets.
How many adult tickets, and how many child tickets, does she buy?
Please explain your work! I will mark brainliest if you do :)
adult ticket = 10
child ticket = 4
Step-by-step explanation:
for example…
adult ticket = xchild ticket = yso that we get a system of equations
9x + 5y = 110…Equation 1
x + y = 14…Equation 2
solve the system of equations, this time I will use the Elimination and Substitution method
9x + 5y = 110
x + y = 14 (multiplied by 5)
↓↓↓↓↓↓↓
9x + 5y = 110
5x + 5y = 70
___________ _
4x = 40
x = 10
to find value of y subtitute x to one of Equation. for example from second Equation…
x + y = 14
10 + y = 14
y = 14 - 10
y = 4
∴ So, the number of each ticket was she bought is 10 adult ticket and 4 child ticket.

Factor Completely.
24x^2 - 44x + 12
Answer:
4(3x−1)(2x−3)
Step-by-step explanation:
Edit*
So first u common factor
24x^2-44x+12
4(6x^2-11x+3)
Then u use the sum product pattern
4(6x^2-11x+3)
4(6x^2-2x-9x-3)
Then find the common factor for both pairs
4(6x^2-2x-9x-3)
4(2x(3x-1)-3(3x-1))
Then rewrite in factor form
4(2x(3x-1)-3(3x-1))
4(2x−3)(3x−1)
