find the maximum value of c=4x+2y subject to the fallowing constraints x≥0 y≥0 2x+2y≤10 3x+y≤9
The maximum value of c=4x+2y subject to the constraints is 14
How to determine the maximum value?The objective function is given as:
c = 4x+2y
The constraints are given as:
x≥0 y≥0
2x+2y≤10
3x+y≤9
Rewrite 2x+2y≤10 and 3x+y≤9 as equations
2x+2y = 10
3x+y = 9
Divide 2x+2y = 10 through by 2
x+y = 5
Subtract x+y = 5 from 3x+y = 9
3x - x + y - y = 9 - 5
Evaluate the difference
2x = 4
Divide by 2
x = 2
Substitute x = 2 in x+y = 5
2+y = 5
Solve for y
y = 3
So, we have
(x, y) = (2, 3)
Substitute (x, y) = (2, 3) in c = 4x+2y
c = 4 * 2 + 2 * 3
Evaluate
c = 14
Hence, the maximum value of c=4x+2y subject to the constraints is 14

Please use elimination method to solve
The answer is x = 4, y = -1 or (4, -1).
We are given :
2x + 7y = 13x + 4y = 8Multiply the 1st equation with 3 and 2nd equation with 2.
3. 3(2x + 7y) = 3(1) ⇒ 6x + 21y = 3
4. 2(3x + 4y) = 2(8) ⇒ 6x + 8y = 16
Now, subtract : Equation 3 - Equation 4.
6x + 21y - 6x - 8y = 3 - 1613y = -13y = -1Substitute in the 1st equation.
3x + 4(-1) = 83x - 4 = 83x = 12x = 4Answer:
(4, - 1 )
Step-by-step explanation:
2x + 7y = 1 → (1)
3x + 4y = 8 → (2)
multiplying (1) by 3 and (2) by - 2 and adding will eliminate x
6x + 21y = 3 → (3)
- 6x - 8y = - 16 → (4)
add (3) and (4) term by term to eliminate x
0 + 13y = - 13
13y = - 13 ( divide both sides by 13 )
y = - 1
substitute y = - 1 into either of the 2 equations and solve for x
substituting into (1)
2x + 7(- 1) = 1
2x - 7 = 1 ( add 7 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
solution is (4, - 1 )

Answer:
y = 4x + 3
Step-by-step explanation:
as the line is parallel to the given equation, the gradient (4x) must stay the same, and as it must pass through the point (-2, -5), we can solve for the y intercept:
to calculate for the y intercept, it is best to express the equation in slope intercept form:
y = mx + b
in this equation, mx stands for the gradient, which ive already highlighted remains 4x, and b stands for the y intercept (which we don't know yet).
y = 4x + b
what we have been given instead is the coordinates for the point this line crosses through (-2,-5) meaning when x = -2, y = -5.
Using this information, we can replace x and y in the equation:
-5 = 4(-2) + b
with consideration to the order of operations, it is important to solve the brackets first
-5 = -8 + b
now to get b by itself add 8 to both sides of the equation:
-5 + 8 = -8 + 8 + b
3 = b
now we remember from the slope intercept equation, b = the y intercept, so we can now solve the equation.
y = 4x + b
replace b with the number we solved for (3).
y = 4x + 3
this is the equation of the line that is parallel to y = 4x + 1, and passes through the point (-2, -5)
hope this helps :)

Louise Tammy Dolores and Cheryl score 78 points in the tennis matches they play. A score consecutive number of points from smallest to greatest in respect to the order of the name is mentioned. How many points does Lewis score? Options:
A. 19 p
B. 20 p
C. 21 p
D. 18 p
Based on the fact that the number of points scored are consecutive numbers, the number of points scored by Lewis is D. 18 points.
How many points did Lewis score?Lewis is the player who scored the least amount of points as they are first in the order.
To find the total number of points scored in the game therefore, you need to assume Lewis's points based on the options, and then sum up the three numbers above it to see if they add up to 78 points.
If Lewis scored 19 points as the lowest then the total points would be:
= 19 + 20 + 21 + 22
= 82 points
If Lewis scored 20 points, the total points would be:
= 20 + 21 + 22 + 23
= 86 points
Lewis therefore scored less than 19 points.
If Lewis scored 18 points, the total is:
= 18 + 19 + 20 + 21
= 78 points
Lewis therefore scored 18 points.

The vertices of an isosceles triangle are A(3, 6), B(7, 2), and C4, 3).
What is the equation of the triangle's line of symmetry?
Answer:
[tex]y=x-1[/tex]
Step-by-step explanation:
The line of symmetry of an isosceles triangle is perpendicular to its base.
Given vertices of the isosceles triangle:
A = (3, 6)B = (7, 2)C = (4, 3)By sketching the triangle with the given points, we can see that AB is its base. (See attached graph).
To find the equation for the line of symmetry, first find the slope of the line AB. To do this, use the coordinates of points A and B and the slope formula.
Define the points:
[tex]\textsf{Let }(x_1,y_1)=(7, 2)[/tex][tex]\textsf{Let }(x_2,y_2)=(3, 6)[/tex][tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{6-2}{3-7}=-1[/tex]
As the line of symmetry is perpendicular to line AB, its slope is the negative reciprocal of the slope of line AB.
Therefore, the slope of the line of symmetry = 1.
The line of symmetry will pass through point C (4, 3).
Therefore, substitute the found slope and the coordinates of point C into the point-slope formula:
[tex]\implies y-y_1=m(x-x_1)[/tex]
[tex]\implies y-3=1(x-4)[/tex]
[tex]\implies y-3=x-4[/tex]
[tex]\implies y=x-1[/tex]
Therefore, the equation of the given isosceles triangle's axis of symmetry is:
[tex]y = x - 1[/tex]
If we graph the points
then we will get AC=CB
That means C is the point from where the axis of symmetry passes

The uppercase letters represent the angles, while the lowercase counterparts are the side lengths opposite said angle. For example, side b is opposite angle B.
Angle B is 41 and angle C is 90 because of the square marker. The remaining angle A is...
A+B+C = 180
A+41+90 = 180
A+131 = 180
A = 180-131
A = 49
Or note that
A = 90 - B = 90 - 41 = 49
This shortcut works since we have a right triangle.
---------
That takes care of the angles. Now onto the sides.
We'll need to use trig ratios to determine the missing sides. There are a few approaches, but this is one you could take
tan(angle) = opposite/adjacent
tan(A) = a/b
tan(49) = a/15
a = 15*tan(49)
a = 17.255526 approximately
Furthermore,
sin(angle) = opposite/hypotenuse
sin(B) = b/c
sin(41) = 15/c
c*sin(41) = 15
c = 15/sin(41)
c = 22.863796 approximately
There is another trig function (cosine) that you could use. Also, you could use the pythagorean theorem once you know two sides of the right triangle.
The pythagorean theorem is a^2+b^2 = c^2

escribe la ecuacion de la circunferencia que tiene como diametro AB donde A(3,-4) y B(-2,-4
La ecuación estándar de la circunferencia es (x - 0.5)² + y² = 2.5².
¿Cómo derivar la ecuación estándar de la circunferencia?
En este problema debemos derivar la ecuación estándar de la circunferencia, cuyo diámetro está comprendido por el segmento de recta entre los puntos A(x, y) = (3, - 4) y B(x, y) = (- 2, - 4). La ecuación estándar de la circunferencia se presenta a continuación:
(x - h)² + (y - k)² = r² (1)
Donde:
(h, k) - Coordenadas del centro.r - Radio de la circunferencia.El centro de la circunferencia es el punto medio del segmento de recta AB:
(h, k) = 0.5 · (3, - 4) + 0.5 · (- 2, 4)
(h, k) = (1.5, - 2) + (- 1, 2)
(h, k) = (0.5, 0)
Y el radio de la circunferencia es la mitad de la longitud del segmento de recta AB:
[tex]r = \frac{1}{2}\cdot \sqrt{(-2 - 3)^{2}+[-4 - (-4)]^{2}}[/tex]
r = 2.5
Por tanto, la ecuación estándar de la circunferencia es (x - 0.5)² + y² = 2.5².
