Answer:
y = - 1 and x = 8
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the lune passes through.
The line passes through (8, - 1) with y- coordinate - 1, thus
y = - 1 ← equation of horizontal line.
--------------------------------------------------------------------
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (8, - 1) with x- coordinate 8 , thus
x = 8 ← equation of vertical line
When in doubt, graph it.
The 3rd and 4th choices are appropriate.
_____
This is what is known as a "logistic function." It is used to model population growth when there is a resource limit. It starts out exponential, but then slows as it reaches the "carrying capacity" of the environment. The lower asymptote is zero; the upper one is the carrying capacity of the resource--here 15/1 = 15.
<span>2x + 8y = –2 --------- (1)
5x + 6y = 9 </span>--------- (2)
(1) x 5 : 10x + 40y = -10 ----------- (1a)
(2) x 2 : 10x + 12y = 18 ----------- (2a)
(1a) - (2a) : 28y = -28
y = -1
Substitute y = -1 into (1)
2x + 8(-1) = –2
2x - 8 = -2
2x = 6
x = 3
Answer : (3, -1) (Answer A)
The correct answer is y = 3x + 2y.
Answer:
Step-by-step explanation:
Distribute:
Y+-3+(-2)(x)+(-2)(1)
Y+-3+-2x+-2
Combine like terms
Y+-3+-2×+2
(-2×)+(y)+(-3+-2)
-2x+y+-5
