What is the maximum value of 3x + 5y in the feasible region?
(3, 7)
(0,7)
(6, 3)
(6, 0)
Answer:
Minimum value is 18
It occurs at P(6,0)
Step-by-step explanation:
The given objective function is
The vertices of the feasible region are .
We plug in the vertices in to feasible region and evaluate to obtain,
P(0,7) = 3(0) + 5(7)
P(0,7) = 0+35
P(0,7) = 35
P(3,7) = 3(3) + 5(7)
P(3,7) = 9+35
P(3,7) = 44
P(6,3) = 3(6) + 5(3)
P(6,3) = 15+15
P(6,3) = 33
P(6,0) = 3(6) + 5(0)
P(6,0) = 18+0
P(6,0) = 18
pls help ill mark brainliest
Answer:
No solution or B
Step-by-step explanation:
Multiply eq1 by 3.
3y=18x+6
3y-18x=12
Regroup:
18x-3y=-6
-18x+3y=12
Add:
0=6???
Impossible
So no solution.
Hope this helps plz mark brainliest :D
Answer:
No solution
Step-by-step explanation:
First we need to solve the equations.
I'll use the combining method
To do the combining method you need to get one of the variables in the first equation to be the negative correspondent to the same variable in the second equation.
(Ex:
If there was 2x in the first equation we would want there to be -2x in the second so they cancel out.)
y=6x+2
subtract 6x from each side to get the variables to line up
y-6x=2
3y-18x=12
To get -6x to equal 18x, we will multiply everything in the first equation by -3
-3y+18x=-6
3y-18x=12
Now combine the two terms
-3y and 3y cancel out
18x and -18x cancel out
-6+12=6
We are left with 0=6.
0 does not equal 6 so there is no solution.
is 20 a prime or composite number.

Leila said that the ratio 2 to 5 may also be written as 2:5. What is another way of writing a ratio?
Answer:
3
Step-by-step explanation:
I have done the test bere
The ratio 2 to 5 can be written as 2 : 5 or 2/5 or 2/(2 + 5) = 2/7 and
5/(2 + 5) = 5/7.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
A ratio a : b can be written as a/b. It can also be written as a/(a + b) and
b/(a + b).
So, the ratio 2 to 5 can be written as 2 : 5 or 2/5 or 2/(2 + 5) = 2/7 and
5/(2 + 5) = 5/7.

The length of each square on the grid represents 1 cm. The scale
from an actual rectangle to the drawing is 24 in. to 1 cm. Make a
new scale drawing where each centimeter represents 16 in.
Label the length and width of your drawing in centimeters.
Answer:
40.64 cm x 40.64 cm
Step-by-step explanation:
The directions say that 1 centimeter = 16 inches.
1 inch = 2.54 centimeters
Multiply by 16.
16 inches = 40.64 centimeters
We know each length of the square is 1 cm or 16 inches, according to the above.
(btw problem says rectangle, a square can be a rectangle.)
Help i need to past this test to get my permit
Answer:
See below for answers
Step-by-step explanation:
1st Problem:
Because the figure is a triangle, it's interior angles will add up to 180 always. Since it's a right triangle, we know one of the angles is 90, but we'll need to set up an equation to solve for x.
90+(2x-2)+(x+5)=180
2x-2+x+5=90
3x+3=90
3x=87
x=29
Therefore, B) 29, is the correct answer
2nd Problem:
Given side lengths of a, b, and c, if a+b<c, then it's a triangle. Since 8+8 is not less than 16, the sides do not make a triangle. The hypotenuse, c, must always be the longest length.
Therefore, A) Not a triangle, is the correct answer
3rd Problem:
To find angle x, we need the last interior angle of the triangle. Since the interior angles of a triangle add up to 180, we once again set up an equation to find the missing interior angle:
21+34+y=180
55+y=180
y=125
Since the missing interior angle is 125 degrees, it is supplementary to angle x, where supplementary angles add up to 180 degrees as well. So we would subtract 125 from 180 to get x. 180-125=55, so angle x is 55 degrees. Therefore, C) 55, is the correct answer.
4th Problem:
Again, use the Interior Angle Theorem to get x:
58+47+x=180
105+x=180
x=75
Therefore, A) 75, is the correct answer
5th Problem:
3,4,5 is a Pythagorean Triple, so it is a right triangle as 3^2+4^2=5^2. It is also scalene because none of the sides are equal to each other.
Therefore, B) Yes, scalene, is the correct answer

By the end of the first quarter of a football game, Al had gained 62 yards and had lost 21 yards. Al Lost an additional 15 yards and gained 18 yards in the second quarter. Replacing represents his total yardage for the first half of the game
Answer:
Y = Q + 44
Step-by-step explanation:
We can easily write an equation for this scenario by making a variable for the unknown number of yards at the start of the first quarter (which would be represented by the letter Q) and then adding or subtracting the gained/lost yards in the second quarter. This would give us the total yardage for the first half of the game which will be represented by the variable Y.
Y = Q + 62 - 21 - 15 + 18 ... we can simplify this by adding and subtracting the given values
Y = Q + 44

Find the discriminate
a = 4, b = -21, c = -18
to keep from getting "mixed up", evaluate the discriminant first ...
b<sup>2</sup> - 4ac = (-21)<sup>2</sup> - 4(4)(-18) = 729
sqrt(729) = 27
x = (21 +/- 27)/8
x = -3/4, x = 6
since the discriminant is a perfect square, the original quadratic will factor ...
4x<sup>2</sup> - 21x - 18 = 0
(4x + 3)(x - 6) = 0
x = -3/4, x = 6
Answer:729
Step-by-step explanation: Use the values of a, b and c to find the discriminant. Which is 729
