Answer:
- question 2 answer is C. (-1,7) and (6,28)
- question 3 answer is A. it is possible for a system of equations composed of linear function and a quadratic function to have 3 solutions.
- question 4 answer is (1,6)
P.s. if any question is wrong then I'm sorry. :(
Step-by-step explanation:
question 4
y=2x^2-5x+9
y= 2x^2+5x-1
y= 2x^2-5x+9=2x^2+5x-1
x=1
y= 2×1^2+5×1-1
y=6
Yes
No
Yes
No
This is because in order to be addition property of equality they have to add/ subtract by the same exact amount on both sides.
The subtraction in the standard form of the polynomial is
.
Given that
Expression;
.
We have to determine
The subtraction of a polynomial.
According to the question
Expression;
.
To find the subtraction of the polynomial follow all the steps given below.
- Step1; Write the expression as an additive inverse.

- Step2; Rewrite terms that are subtracted as the addition of the opposite.

![\rm 6m^5 + 3 + (-m^3) + (-4m) + m^5 + (2m^3) + 4m + (-6)\\\\(6m^5 + m^5) + [3 + (-6)] + [(-m^3) + (-2m^3)] + [(-4m) + 4m]\\\\](https://tex.z-dn.net/?f=%5Crm%206m%5E5%20%2B%203%20%2B%20%28-m%5E3%29%20%2B%20%28-4m%29%20%2B%20m%5E5%20%2B%20%282m%5E3%29%20%2B%204m%20%2B%20%28-6%29%5C%5C%5C%5C%286m%5E5%20%2B%20m%5E5%29%20%2B%20%5B3%20%2B%20%28-6%29%5D%20%2B%20%5B%28-m%5E3%29%20%2B%20%28-2m%5E3%29%5D%20%2B%20%5B%28-4m%29%20%2B%204m%5D%5C%5C%5C%5C)
- Step4; the resulting polynomial in standard form is,
![\rm (6m^5 + m^5) + [3 + (-6)] + [(-m^3) + (-2m^3)] + [(-4m) + 4m]\\\\ 7m^5-3m^2-3](https://tex.z-dn.net/?f=%5Crm%20%286m%5E5%20%2B%20m%5E5%29%20%2B%20%5B3%20%2B%20%28-6%29%5D%20%2B%20%5B%28-m%5E3%29%20%2B%20%28-2m%5E3%29%5D%20%2B%20%5B%28-4m%29%20%2B%204m%5D%5C%5C%5C%5C%207m%5E5-3m%5E2-3)
Hence, the subtraction in the standard form of the polynomial is

Answer:
The slope is 2/3 and the y intercept is 5/9
Step-by-step explanation:
This is written in the form
y= mx+b where m is the slope and b is the y intercept
y = 2/3x +5/9
m = 2/3 and b=5/9
The slope is 2/3 and the y intercept is 5/9
