Answer:
Step-by-step explanation:
(5x^3+4x^2)−(6x^2−2x−9)
To find the opposite of 6x^2−2x−9 find the opposite of each term.
5x^3+4x^2−6x^2+2x+9
Combine 4x^2 and 6x^2 to get −2x^2.
5x^3-2x^2+2x+9
Actually in this case we will make use of the z test
statistic. In which we calculate for the z score and then use the standard
normal distribution tables to find for the P value at the calculate z score.
z = (x – u) / s
z = (97 – 98) / 2
z = -0.5
The z value should be greater than 1.65 to for the null
hypothesis to be accepted. Hence rejected.

Answer: 2y + 11x = -104
Step-by-step explanation:
The formula for calculating equation of line given two points is :
=
= -10
= -8
= 3
= -8
substituting the values into the formula , we have :
=
=
2(y - 3 ) = -11 ( x +10 )
2y - 6 = -11x - 110
2y + 11x = -110 + 6
2y + 11x = -104
Therefore : the equation of the line in standard form is 2y + 11x = -104
