Answer:
A : quadratic trinomial
Step-by-step explanation:
Given
(3x² - 11x - 4) - (2x² - x - 6)
Distribute both parenthesis, noting the second is distributed by - 1
= 3x² - 11x - 4 - 2x² + x + 6 ← collect like terms
= x² - 10x + 2 ← this is a quadratic with 3 terms, thus quadratic trinomial → A

Answer:
312.5
Step-by-step explanation:
Since it is $250 plus 20 cents per poster, the equation is 0.20p+250. It is $1 per poster at store and you want to know when the cost is going to be the same so you set them equal to each other.
0.20p+250=p
250=0.80p
312.5=p
Answer:
4+16=0
4=−16=162
2=±4
Case 1 2=+4
=±2√
√=±(12√+12√)
=±2‾√+2‾√
Case 2 2=−4=43
=±23/2=±2()1/2
∵√=±(12√+12√)
=±(2‾√+2‾√)
So in all,
=2‾√+2‾√
=−2‾√+2‾√
=2‾√−2‾√
=−2‾√−2‾√
Let √=+
Squaring both sides, we have
=(+)2
0+1=2−2+2⟹
2−2=0(1)
2=1
=12
Plugging in (1) … ⟹
2−1(2)2=0
4=14
2=12
∴=±12‾√
∴=±12‾√
∴√=+=±(12+12)
This can also be shown as below
√=12+12
Or
√=−12−12 \
A ray is a line with one end. It starts at a given point and goes off in a certain direction forever to infinity. The point where the ray starts is called the endpoint.
Y-intercept = -2
Equation of the line is
Y=x-2
