Which system of linear inequalities is represented by the graph? O y=x-2 and x-2y 4 O y=x + 2 and x + 2y = 4 O y=x-2 and x + 2y = 4 O y =x-2 and x + 2y =-4
Answers
The two inequalities are (option c) y > x - 2 and2y + x < 4
Given,
Let's start by locating the red-hued area.
If the shadow is visible to be over the line, then the situation will be as follows:
y > ax + b
Hence the equation for the line is ax + b.
The slope is a, and the y-intercept is b.
The line in the graph intersects the y-axis at y = -2, which results in:
b = -2
Two points on the line are required to determine the slope; these points are (0, -2), and (2, 0)
We are aware of the slope for a line passing through the points (x1, y1) and (x2, y2) as follows:
a = (y2 - y1)/(x2 - x1) (x2 - x1)
The slope for this line will then be:
a = (0 - (-2))/(2 - 0) = 2/2 = 1
Then this line's equation is:
1x - 2
And here's the inequality:
y > x - 2.
The shaded area of the blue one is below the line, thus we will have:
y < ax + b
The y-intercept in this situation is y = 2.
This line crosses through the points (0, 2) and, as can be seen (4, 0)
The slope is then:
a = (0 - 2)/(4 - 0) (4 - 0) = -2/4 = -1/2
This inequality is then:
y < (-1/2)x + 2
If we rewrite this using the choices, we get the following:
y < (-1/2)x + 2
2y < -x + 2 ×2
2y + x < 4
The two inequalities are (option c) y > x - 2 and2y + x < 4

Answers
Let's call X the cost of one bunch of roses and Y the cost of one palm.
Then, the first order was for 13 bunches of roses and 4 palms, totaling $487, so:
13X + 4Y = 487
Additionally, the second order was for 6 bunches of roses and 2 palms, totaling $232, so:
6X + 2Y = 232
Then, solving for Y on the first equation, we get:
[tex]\begin{gathered} 13X+4Y=487 \\ 4Y=487-13X \\ Y=\frac{487-13X}{4} \\ Y=\frac{487}{4}-\frac{13}{4}X \\ Y=121.75-3.25X \end{gathered}[/tex]Replacing on the second and solving for X, we get:
[tex]\begin{gathered} 6X+2Y=232 \\ 6X+2(121.75-3.25X)=232 \\ 6X+2\cdot121.75-2\cdot3.25X=232 \\ 6X+243.5-6.5X=232 \\ -0.5X+243.5=232 \\ -0.5X=232-243.5 \\ -0.5X=-11.5 \\ X=\frac{-11.5}{-0.5} \\ X=23 \end{gathered}[/tex]Then, we can replace the value of X and calculated the value of Y as:

bit strings of length eight do not start with a one or do not end with a one are there.
A string is a combination which is made up of only two characters, either 1 or 0.
So, the combinations of the string can be found,
If the length of the bit string is 5, it means it will have 5 characters.
If this string either start with two zeroes or end with two zeroes. It mean there are only three positions are remaining which have two choices available for each place.
So, the total bit strings possible are,
= 2×(1×1×2×2×2)
= 16
16 such bit strings are possible.
If the length of the bit string is 6, it means it will have 6 characters.
If this string either do not start with two zeroes or do not end with two zeroes. It mean there are only four positions are remaining which have two choices available for each place.
So, the total bit strings possible are,
= 2×(1×1×2×2×2×2)
= 32
So, 32 such strings are possible.
Now, If the length of the bit string is 7, it means it will have 7 characters.
If this string either start with four ones or end with four ones. It mean there are only three positions are remaining which have two choices available for each place.
So, the total bit strings possible are,
= 2×(1×1×1×1×2×2×2)
= 16
So, 16 such strings are possible.
If the length of the bit string is 8, it means it will have 8 characters.
If this string either do not start with one and do not end with one. It mean there are only seven positions are remaining which have two choices available for each place.
So, the total bit strings possible are,
= 2×(1×2×2×2×2×2×2×2)
