what system of linear inequalities is represented by the graph?
Answer:
y > 2x - 4 and y ≤ [tex]\frac{x}{2}-1[/tex]
Step-by-step explanation:
In this question we will find the equations of the lines first then decide the inequality sign.
Dotted line in the graph passes through two points (2, 0) and (0, -4)
Let the equation of the line is y = mx + c
Where m = slope and c = y-intercept
Slope (m) of the line will be = [tex]\frac{y-y'}{x-x'}[/tex]
m = [tex]\frac{0+4}{2-0}[/tex]
m = 2
y-intercept of the line = (-4)
So, equation of the line will be y = 2x - 4
Now we see the shaded area is above the dotted line so inequality will be
y > 2x - 4
Now for the bold line
Let the equation of this line is y = m'x + c'
This line passes through points (2, 0) and (0, -1)
then slope of the line m' = [tex]\frac{y-y'}{x-x'}[/tex]
m = [tex]\frac{0+1}{2-0}[/tex] = [tex]\frac{1}{2}[/tex]
y-intercept = c = -1
Then equation of the line will be
y = [tex]\frac{x}{2}-1[/tex]
Since shaded area is below the bold line therefore, inequality sign will be "less than equal to"
Inequality of the bold line will be y ≤ [tex]\frac{x}{2}-1[/tex]
System of the linear inequalities will be
y > 2x - 4 and y ≤ [tex]\frac{x}{2}-1[/tex]

Tim made a down payment of $1,000. He pays $450 for 36 months. What is the total amount he pays for the car?
Answer:
$ 17,200
Step-by-step explanation:
Given,
The amount of down payment = $ 10000,
Also, monthly payment = $ 450,
Number of months = 36,
So, the total payment ( except down payment ) = number of months × monthly payment
= 36 × 450
= $ 16200,
Hence, the total amount paid for the car = down payment + total payment
= $ 1,000 + $ 16,200
= $ 17,200
In the diagram below, what is the approximate length of the minor Arc de? "if you can, explain please"
Answer:
D) 23.6 cm
Step-by-step explanation:
We first find the circumference of the circle. Circumference is given by the formula
C = 2πr, where π = 3.14 and r is the radius. The radius of our circle is 15 cm; this gives us
C = 2(3.14)(15) = 94.2.
Next we find the portion of the circumference associated with the given arc. The measure (in degrees) of the arc is 90°; this makes it 90/360 of the circle. 90/360 simplifies to 1/4; this means this arc is 1/4 of the circumference:
1/4(94.2) = 23.55
This rounds to 23.6.
Points J, K, L, and M are midpoints of the sides of the rectangle EFGH. Prove that quadrilateral JKLM is a rhombus by finding the lengths of the sides. The diagram is not drawn to scale.
Quadrilateral JKLM is a rhombus because its sides are all equal in length. By using the midpoints of the rectangle EFGH, we find that JK and LM are both 2a in length, and KL and MJ are both 2b in length, confirming that all four sides are equal.
To prove that quadrilateral JKLM is a rhombus, we find the lengths of its sides.
Since J, K, L, and M are midpoints of the sides of rectangle EFGH, the segments connecting them will be parallel to the sides of EFGH and half the length.
We can use the coordinates of F(-a,b), G(a,b), H(a,-b), and E(-a,-b) to find the lengths:
JK is parallel to EH and GH, so its length is half of EH and GH, and since E and G are on the same vertical line, the length of JK is a - (-a) = 2a.
KL is parallel to EG and FH, so its length is also half of EG and FH, and since E and F are on the same horizontal line, the length of KL is b - (-b) = 2b.
LM is parallel to EH and GH, hence its length is the same as JK which is 2a.
MJ is parallel to EG and FH, hence its length is the same as KL which is 2b.
Given that JK = LM and KL = MJ, and all are equal to 2a or 2b, quadrilateral JKLM has all sides of equal length. Therefore, it is a rhombus.
The probable question may be:

GIven :
The point (-7, -24) is on the terminal ray of angle θ which is in standard position.
To determine the trigonometric function first determine the value of the hypotenuse and to determine the value of the hypotenuse, the Pythagorean theorem can be used.
[tex]\rm H^2 = P^2 + B^2[/tex]
where H is the hypotenuse, B is the base, and P is the perpendicular.
Now, substitute the value of known terms in the above equation.
[tex]\rm H^2 = 7^2+24^2[/tex]
[tex]\rm H^2=49+576[/tex]
[tex]\rm H^2 = 625[/tex]
H = 25
Now, the values of the trigonometric functions are as follows:
[tex]\rm cos\theta=\dfrac{-7}{25}[/tex]
[tex]\rm sin\theta=\dfrac{-24}{25}[/tex]
[tex]\rm tan\theta=\dfrac{24}{7}[/tex]
[tex]\rm cosec\theta=\dfrac{25}{-24}[/tex]
[tex]\rm sec\theta=\dfrac{25}{-7}[/tex]

To find the six trigonometric values for angle θ (-7, -24) on the terminal ray, we can use sine, cosine, tangent, cosecant, secant, and cotangent ratios.
Explanation:The given point (-7, -24) lies on the terminal ray of an angle in standard position, denoted by θ. To find the six trigonometric values for angle θ, we can use the values of the coordinates of the point. The coordinate (-7) represents the x-value (adjacent side) and the coordinate (-24) represents the y-value (opposite side).
We can use the trigonometric ratios: sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot), to find the values.
Here, sinθ = y/r = (-24)/7.6, cosθ = x/r = (-7)/7.6, tanθ = y/x = (-24)/(-7), cscθ = 1/sinθ, secθ = 1/cosθ, and cotθ = 1/tanθ. By substituting the respective values, we can find all six trigonometric values.

The radius of a large sphere is 8 times the radius of a small sphere. the surface area of the large sphere is how many times the surface area of the small sphere?
The large sphere is 64 times the surface area of the small sphere.
What is a sphere?A sphere is a geometrical object that is a three-dimensional analogue to a two-dimensional circle. A sphere is the set of points that are all at the same distance r from a given point in three-dimensional space. That given point is the centre of the sphere, and r is the sphere's radius.
Given that, the radius of a large sphere is 8 times the radius of a small sphere.
Let the radius of a small sphere be x, then the radius of a large sphere is 8x.
We know that, the surface area of a sphere is 4πr².
Here, surface area of a small sphere = 4πx²
The surface area of a large sphere = 4π(8x)²
= 256πx²
Now, 256πx²/4πx² =64
Therefore, the large sphere is 64 times the surface area of the small sphere.

B) $59.65
C) $94.49
D) $138.93
(I would really appreciate
it if someone will help me)
Answer:
Option C. $94.49
Step-by-step explanation:
Jaime had a balance in his bank account on Sunday = $37
The table shows his account activity for the next four days.
From the given table we add all the deposits to his balance and then subtract all the withdrawals.
Balance on Sunday + Deposits
= 37.00 + 17.42 + 62.29 = $ 116.71
Now we subtract all the withdrawals
= 116.71 - (12.60 + 9.62)
= 116.71 - 22.22 = $94.49
The balance would be $94.49 in Jaime's account after his deposit on Thursday.

Find the value of angle c?? Please help
The angles with measures x and 4x are complementary angles. which is the value of x?
Answer:
x=18 degrees
Step-by-step explanation:
Hello
by definition, two angles are called complementary angles, if the sum of their degree measures is 90. Each angle is called complement of the other.
A = angle 1=x
B=angle 2 =4x
A and B are complementary angles,hence
A+B=90
replacing
[tex]x+4x=90\\\\5x =90\\x=\frac{90}{5} \\x=18\ degrees[/tex]
A=18 degrees
B=4*x
B=72 degrees
x=18 degrees
