and y=
Answers
Answer:
Minimum Values:
x = 0, y = 1, z = 3
Maximum Values:
x = 7 , y = 11 , z = 47
Step-by-step explanation:
FOR MINIMUM VALUES:
0<= x <= 7
It is clear from the above inequality that the minimum value of x must be 0.
y>= 1
This inequality shows that the minimum value of y must be 1. Using these minimum values of x and y to get the minimum value of z:
z = 2x + 3y
z = (2)(0) + (3)(1)
z = 3 (Minimum)
FOR MAXIMUM VALUES:
0<= x <= 7
It is clear from the above inequality that the maximum value of x must be 7.
x + y <= 11
To calculate maximum value of y we can use the minimum value of x in this inequality:
0 + y <= 11
y <= 11
Hence, the maximum value of y is 11.
Using these maximum values of x and y to get the maximum value of z:
z = 2x + 3y
z = (2)(7) + (3)(11)
z = 47 (Maximum)

Answer:
x = - 6, x² = [tex]\frac{7}{2}[/tex]
Step-by-step explanation:
[tex]2x^{2}[/tex] + 12x - 7x - 42 = 0
2x^{2} (x + 6) - 7 (x + 6) = 0
(x + 6) x (2x - 7) = 0
x + 6 = 0
2x - 7 = 0
x = - 6
x = [tex]\frac{7}{2}[/tex]
x = - 6, x² = [tex]\frac{7}{2}[/tex]

which equation is perpendicular to y= -2x + 5 ?
A) y= -2x -5
B) y= 2x -3
C) y= 1/2x -2
D) y=-1/2x+1
Answers
The original equation had -2 as the slope. The opposite of -2 is 1/2.
When the number is negative, the opposite of it is positive.
And in order for them to be completely opposite, you have to flip the number. So 2 turned into 1/2, since the denominator of 2 is 1.
And so since the opposite slope is 1/2, C is the correct answer.

What is the solution to the system of equations2x + 3y = 40andy=x + 10?
A
x = 2; y = 12
B
x = 4; y = 14
C x = 12; y = 2
D x = 14; y = 4
Answers
Answer:
A is the correct answer
Step-by-step explanation:
If you plug y=x+10 in for the Y variable you just have to solve by multiplying.
1.) It should look like this:
2x + 3(x +10) = 40
2.) You will distribute the three which will make the equation look like this:
2x + 3x + 30 = 40
3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.
Hope that helps

What is happening to the variable?
How do you solve for the variable?
Answers
Answer:
n=15
Step-by-step explanation:
(subtract 6 from both sides of the equation.)
6+n/5=9
6+n/5-6=9-6
(Now you will have to simplify.)
n/5=3
(You will have to multiply all terms by the same value to eliminate fraction denominators.)
n/5=3
5xn/5=5x3
(You will now have to simplify.)
n=15
And that's how you get your answer.
