Write an inequality that represents the graph.
Answer:
y > x + 2
Step-by-step explanation:
positive slope so positive x it translated 2 units UP the yaxis so +2 it's a DASHED line so that means it's the regular signs if it was a SOLID line u would have to use the less than equal too signs the shading is ABOVE the line so it's going to be a greater than sign !!I appreciate all answers I like

A boy starts from a point A and walks 4 km due east to B. He then changes direction and walks 3 km due north to C. Find the distance of C from A.
Answer:
Distance C from A =5km
Step-by-step explanation:
use the Pythagoras theorem's
{AC}^{2} = {BC}^{2} + {AB}^{2}
AC=✓3^2 + 4^2
AC = ✓9+16
AC = ✓25
AC = 5 km
therefore, C from A = 5 km

An angle between 0 and 2π that is coterminal with 960° is
Answer:
4 pi/3
Step-by-step explanation:
960 degrees in standard position is the same thing as 960-360 = 600 degrees in standard position because rotating the second line 360 degrees just brings it back to where it started.
Do it again to get 600 - 360 = 240
240 degrees would end up in the same spot as 600 degrees and 960 degrees, so they are all coterminal.
Convert 240 degrees to radians:
240 * pi/180 = 4pi/3.

Explain or show that the point (5, -4) is a solution to this system of equations:
3x - 2y = 23
2x + y = 6
Answer:
see explanation
Step-by-step explanation:
If (5, - 4) is a solution to the system then both equations will be true when (5, - 4) is substituted into them.
Substitute (5, - 4) into the left side of the equations and if equal to the right side then (5, - 4) is a solution.
3(5) - 2(- 4) = 15 + 8 = 23 = right side
2(5) + (- 4) = 10 - 4 = 6 = right side
Then (5, - 4) is a solution to the system of equations.
or by solving
3x - 2y = 23 → (1)
2x + y = 6 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate the y- term
4x + 2y = 12 → (3)
Add (1) and (3) term by term to eliminate y, that is
7x = 35 ( divide both sides by 7 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (2)
2(5) + y = 6
10 + y = 6 ( subtract 10 from both sides )
y = - 4
Solution is (5, - 4 )
Using the concept of simultaneous equation, the solution to the system of equations is (5, - 4)
Given the system of linear equations :
3x - 2y = 23 _______(1)2x + y = 6 ________ (2)From (2) :
y = 6 - 2x ______(3)Substitute (3) into (1)
3x - 2(6 - 2x) = 23
3x - 12 + 4x = 23
7x = 23 + 12
7x = 35
Divide both sides by 7 to isolate x
x = 35 / 7
x = 5
From (3)
y = 6 - 2(5)
y = 6 - 10
y = -4
Therefore, the solution to the system of equation is (5, - 4)

What is the slope of the line that passes through the points (3,9) and (7,5)? Write
your answer in simplest form.
Answer:
M = -1
Step-by-step explanation:
Use the slope formula:
M = (y2-y1)/(x2-x1)
M = (5-9)/(7-3)
M = -1
The required slope for the lines -1.
Given that,
To determine the slope of the line that passes through points (3,9) and (7,5).
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m = tanx, where x is in degrees.
What is simplification?The process in computation 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,
Slopes of the line can be given as,
m = [y₂ - y₁ ] / [x₂ - x₁]
for points, (3,9) and (7,5)
m = 5 - 9 / 7 - 3
m = -4 / 4

You have a bull's eye where each section is 2" wide as shown in the diagram. Find the following probabilities.
Answer:
a) 1/16
b) 7/16
Step-by-step explanation:
a) The area of the outside circle is π (8")² = 64π in².
The area of the center circle is π (2")² = 4π in².
So the probability is (4π / 64π) = 1/16.
b) The area of the outside strip is π [(8")² − (6")²] = 28π in².
So the probability is (28π / 64π) = 7/16.

ΔCSR and ΔMDR share ∠CRS
Since lines [tex]n[/tex] and [tex]k[/tex] are parallel, ∠C ≅ ∠M and ∠S ≅ ∠D. These are corresponding angles.
Either of these sets of angles could be used along with ∠CSR to prove that ΔCSR and ΔMDR are similar because of AA.
Ohama is landing a plane on the runway. He's trying to decide where he should deploy the plane's landing gear so that the plane comes to a stop exactly at the end of the runway. The runway is 600 yards long, and the plane will travel half the distance with the landing gear than without the landing gear. Where should he deploy the landing gear ?
Answer:
Let's define:
A = distance traveled before deploying the landing gear
B = distance traveled after deploying the landing gear.
We must have that the sum of those two distances must be equal to 600 yards.
A + B = 600 yd.
And we know that:
" the plane will travel half the distance with the landing gear than without the landing gear."
Then we have that:
B = A/2.
Now we can replace this last equation in the first one:
A + B = 600yd
A + A/2 = 600yd.
(3/2)*A = 600yd.
A = (2/3)*600yd = 400yd.
Ohama should deploy the landing gear 400 yd into the runway.

True or False? When Liesl used the quadratic formula to solve a quadratic equation, she noticed the value of the discriminant was a perfect square. She immediately determined that she could have factored the quadratic equation she was solving.
Liesl is correct, if the discriminant is a perfect square, then we can factorize the quadratic equation.
Is the statement true or false?For a quadratic equation:
y = a*x^2 + b*x + c
The discriminant is:
D = b^2 - 4ab
Notice that for the equation:
0 = a*x^2 + b*x + c
The solutions are given by:
[tex]x = \frac{-b \pm \sqrt{D}}{2a}[/tex]
If D is a perfect square, then we know that the square root has solutions, so there are two values:
[tex]x_1 = \frac{-b + \sqrt{D}}{2a}\\\\x_2 = \frac{-b - \sqrt{D}}{2a}[/tex]
Now with these solutions, we can factorize our equation as:
[tex]y = a*(x - ( \frac{-b + \sqrt{D}}{2a}))*(x - ( \frac{-b - \sqrt{D}}{2a}))[/tex]
So Liesl is correct, if the discriminant is a perfect square, we can factorize the quadratic equation.

The number of tickets sold each day for an upcoming performance is given by p(x) = -0.4x2 + 8.8x + 13, where x is the number of days since the concert was first announced. When will daily ticket sales peak and how many tickets will be sold that day?
Answer:
The maximum sale of the tickets is 158 on the [tex]11^{th}[/tex] day.
Step-by-step explanation:
The number of tickets sold each day, p(x), for an upcoming performance is
[tex]p(x)=-0.4x^2+8.8x+13[/tex]
where x is the number of days since the concert was first announced.
For peak sales, the point of maxima has to be determined.
So, differentiate the function of the number of tickets sold each day, p(x), with respect to the number of days, x, and equate it to zero to get the extremum point (maxima or minima), i.e.
[tex]\frac {p(x)}{dx}=0[/tex]
[tex]\Rightarrow -0.8x+8.8=0[/tex]
[tex]\Rightarrow x=\frac{8.8}{0.8}=11[/tex]
Now, check the sign of the second derivative at x=11, to ensure the obtained point is corresponding to the maxima or minima,
[tex]\frac {p^2(x)}{dx^2}=-0.8[/tex]
As the second derivative is negative, so x=11 is the point corresponding to maxima.
Hence, on the [tex]11^{th}[/tex] day the daily ticket sales will be at the peak.
Putting x=11 in the function p(x) to get the number of tickets sold that day.
[tex]p(x=11)= -0.4(11)^2+8.8(11)+13[/tex]
[tex]\Rightarrow 158.2.[/tex]
The number of tickets should be an integer, the obtained peak value is 158.2 so the higher integral value is not possible but the lower integral value is possible.
So, the maximum sale of the tickets is 158 on the [tex]11^{th}[/tex] day.

Answer:
c
Step-by-step explanation:
The equation =( denominater * derivative of numerator - numerator * derivative of denominator) / denominator ^2
so the qstn is (x^2 + 3x +2) / (x+3)
apply the values as the above eqtn states
ie,[ (x+3) * derivative of (x^2 +3x + 2)] - [( x^2 +3x + 2) *derivative of (x+3)] /
(x+3)^2
derivative of numerator, (x^2 +3x + 2) is 2x+3
" of denominator, (x+3) is 1
so we get
[(x+3)* (2x + 3 ) - (x^2 +3x + 2) *1 ] / (x+3)^2
open the brackets
[ 2x^2 + 3x + 6x + 9 - x^2 +3x + 2 ] / (x+3)^2
subtract similar terms and we get the final answer in option c
