It has a slope of -2/2 meaning it goes down and over 2. So the antis A
Answer:
(4, -1) is not a solution to the system
Step-by-step explanation:
The first point: (4,-1) doesn't satisfy the first inequality:
since we get to an absurd, because -1 cannot be strictly smaller than -1!
Answer:
x = 5
Step-by-step explanation:
5 - 1 = 4
4/2 =2

Answer:
a = -3/2 = -1.5
Step-by-step explanation:
(1+ax) (2+3x)³
Formula
(a+b)^3=a^3+3a^2b+3ab^2+b^3
(1 + ax) [ 2^3 + 3*2^2*3x + 3*2*(3x)^2 + (3x)^3]
(1 + ax) [ 8 + 12*3x + 6*9x^2 + 27x^3]
8 + 12*3x + <u>6*9x^2</u> + 27x^3 + 8ax + <u>36ax^2</u> + 54ax^3 + 27ax^4
coefficient of x^2 is zero
54x^2 + 36ax^2
54 + 36a = 0
36a = -54
a = -3/2
Answer:
P(5, 0 )
Step-by-step explanation:
Where the line crosses the x- axis the y- coordinate of the point P is zero.
Substitute y = 0 into the equation and solve for x
2x + 3(0) - 10 = 0 , that is
2x - 10 = 0 ( add 10 to both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Thus P = (5, 0 )
