Answer:
See the attached image for the graph of the first system.
Step-by-step explanation:
Here's how to graph the first system.
Start with the inequality [tex]-y \le -2x-3[/tex]. You can make this easier to work with by multiplying through by -1. Remember to switch the inequality sign when multiplying by a negative number. OK, you get the inequality
[tex]y \ge 2x+3[/tex].
The graph will be a half-plane -- all the points on one side of a line. The line that is the boundary of the half-plane has an equation: [tex]y=2x+3[/tex] -- just use an = sign instead of the inequality sign.
Graph the line.
The equation of the line is in slope-intercept form: y = mx + b, so you can tell the y-intercept is 3 and the slope is 2 (think of it as a fraction 2/1). Graph the line by going to the point (0, 3) -- the y-intercept -- then use the slope 2/1 interpreted as "rise over run" to go up 2 units and right 1 unit, arriving at the point (1, 5). Draw the line through those points, (0, 3) and (1, 5).
Now you have to decide which side of the line the inequality [tex]y \ge 2x+3[/tex] is describing. To do this, pick a point which is not on the line, plug its coordinates into the inequality; if the result is true, shade the side of the line the point you picked is on (if false, shade the other side!)
An easy point to pick in this case is the origin, (0, 0). Put zeros in for x and y in the inequality, and you'll get the statement [tex]0 \ge 2(0)+3 \, \Rightarrow \, 0 \ge 3[/tex]. That's false, so shade the side of the line not containing the origin. In the image below, the shading is in purple.
All right, now for the other inequality, [tex]x+2\le 0[/tex]. Subtract 2 from both sides and the inequality becomes [tex]x \le -2[/tex]. This, too, graphs as a half-plane whose boundary line has equation [tex]x=-2[/tex]. Graph the line. A line with an equation that has x in it but not y is a vertical line with all its x-coordinates equal to the number on the right side of the equation. This line is vertical and goes through points such as (-2, 0).
Pick a point not on the line (the origin works again). Put the coordinates into the inequality to get [tex]0\le -2[/tex] which is false. Shade the side of the vertical line which does not contain the origin. In the image below, the shading is in black.
Finally, YAY! \o/ , the solutions to the system are all the points in the plane that got shaded twice. In the image, they are the cross-hatched points above the purple line and to left of the black line.
Note: If you get a system with three inequalities, you'll be graphing three half-planes and looking for points that got shaded three times!
Note: One of your questions has the inequalities [tex]x \ge 0[/tex] and [tex]y \ge 0[/tex] in it. These two inequalities say that the x and y coordinates are both positive or zero, confining your attention to Quadrant I in the upper-right part of a graph, above the x-axis and to the right of the y-axis.
C =tid circumference = 3.14 x diameter
If a circle has the diameter of 24 ft, what is the circumference?
ft.
Answer:
75.36.
Step-by-step explanation:
C= Pi D (Pi times diameter) so you do 3.14x 24 which then you get your answer of 75.36.

Answer:
Angle NKQ is 68 Degrees.
Step-by-step explanation:
With this, consider the arc that Angle NPQ is making. It is making an arc of 112 degrees since the Angle is coming out from the radius of the circle.
Now, there is also the arc 248 degrees for the remainder of the circle that is not within this angle's reach.
Since Angle NKQ shares these arcs, we can use the equation:
Big Arc + Small Arc / 2
to get the measure of this angle
(248 - 112) / 2
With this, Angle NKQ is 68 degrees.

Answer:
A) the down payment was $ 1,746, B) the total amount of the montly payments is $ 11,632.32, C) the total cost is $ 13,378.32, and D) the finance charge is 14.93%.
Step-by-step explanation:
Given that Carl bought a sailboat for $ 11,640 on the installment plan, and the installment agreement included a 15% down payment and 18 monthly payments of $ 646.24 each, to determine A) how much is the down payment, B) what is the total amount of the monthly payments, C) what is the total cost she paid for the sailboat on the installment plan, and D) what is the finance charge, the following calculations must be performed:
A) 11,640 x 0.15 = 1,746
B) 18 x 646.24 = 11,632.32
C) 11,632.32 + 1,746 = 13,378.32
D) 11,640 = 100
13,378.32 = X
13,378.32 x 100 / 11,640 = X
1,337,832 / 11,640 = X
114.93 = X
Therefore, A) the down payment was $ 1,746, B) the total amount of the montly payments is $ 11,632.32, C) the total cost is $ 13,378.32, and D) the finance charge is 14.93%.

You select a marble without looking and then put it back. If you do this 12 times, what is the best prediction possible for the number of times you will pick a pink marble? there are 3 pink marbles
Answer:
6 times
Step-by-step explanation:
If there are total of 6 marbles and 3 are pink, then you will have a one half (or 50%) chance of picking a pink marble. Because you put the marble back each time, your chance of picking a pink marble remains the same every time.
So one half of 12 is 6. You are predicted to pick a pink marble 6/12 times.

HURRY PICTURE INCLUDED
The highlighted part of this picture is a good representation of which
geometric term?
OA) line segment
B) ray
OC) line
OD) plane
The highlighted part is called Ray.
By the way, In geometry, a ray can be defined as a part of a line that has a fixed starting point but no endpoint.Name the angle and the intercepted arc.
Answer:
The angle formed is ∠LMK and the intercepted arc is LK.
Step-by-step explanation:
The given figure shows a circle of radius M. L and K are other points on the circle.
The distance from the center of the circle to a point on the circle is called radius.
LM and MK are the radius of the circle or
LM = MK
The angle formed is ∠LMK.
The intercepted arc is LK.
Reflect the vector (-3,5) across
the line y=x.
Answer:
(5, - 3 )
Step-by-step explanation:
Under a refection in the line y = x
a point x, y ) → (y, x ), then
(- 3, 5 ) → (5, - 3 )
The reflection vector is (5, -3) after reflecting over line y = x the answer is (5, -3).
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
We have:
The vector is (-3, 5)
The reflection line is y = x
The transformation rule:
(x, y) → (y, x)
(-3, 5) → (5, -3)
Thus, the reflection vector is (5, -3) after reflecting over line y = x the answer is (5, -3).

Answer:

Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 9^2 = 15^2
a^2 +81 =225
Subtract 81 from each side
a^2 = 225-81
a^2 = 144
Take the square root of each side
sqrt(a^2) = sqrt(144)
a=12
Answer:
a = 12 meters
Step-by-step explanation:
Use pythagorean theorem to identify the missing leg
pythagorean theorem = [tex]a^2+b^2=c^2[/tex]
In this case, we are looking for a so...
[tex]a^2+b^2=c^2[/tex]
[tex]a^2+9^2=15^2[/tex]
[tex]a^2+81=225[/tex]
[tex]a^2=225-81[/tex]
[tex]a^2=144[/tex]
It doesn't make sense for a to be equal to 144 so we must square root 144
144 = [tex]12^{2}[/tex] meters
Final Answer: 12 meters

Enter the ratio equivalent to tan(R).
Answer:
tan r = 35/12
Step-by-step explanation:
you use the rule tan=opposite/adjacent
The required ratio equivalent to tan(R) for triangle RTS is 35 / 12.
A triangle RTS is given with perpendicular = 35 base = 12 and the hypotenuse = 37
What is the triangle?The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°
What is simplification?
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
In order to find out the ratio equivalent to tan(R).0
We know that,
tan(r) = perpendicular / base
