Answer:

Option (A)

Step-by-step explanation:

Here, x+ 2y =8

c=x+3y

x≥2

y≥0

By considering the options (A) and (B)

For option (A)

x=8 and y=0

x+2y=8

put values of x and y in equation

8+2×0=8, which satisfies the equation

now  c= 8+3×0=8

Now,  for option (B)

x=2 and y=3

x+2y=8

put values of x and y

2+2×3=8, which satisfies the equation.

now c= 2+3×3=11

As we have to find the minimum value of c.

hence we take c=8

Hence, option (A) is correct.

Graph the inequalities to find the vertices of the shaded region: (2, 3) and (8, 0).

Now, evaluate the the function C = x + 3y at those vertices to find the minimum value.

C = x + 3y at (2, 3)  ⇒  C = (2) + 3(3)   ⇒  C = 2 + 9   ⇒   C = 11

C = x + 3y at (8, 0)  ⇒  C = (8) + 3(0)   ⇒  C = 8 + 0   ⇒   C = 8

The minimum value occurs at (8, 0) with a minimum of C = 8

Answer: A

What is the equation of a line that contains the point (2,-5) and is parallel to the line y=3x-4
aev [14]

Answer:

\large\boxed{y=3x-11}

Step-by-step explanation:

\text{Let}\\\\k:y=m_1x+b_1\\\\l:y=m_2x+b_2\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\\\l\ \parallel\ k\iff m_1=m_2\\\\===================================\\\\y=3x-4\to m_1=3\\\\\text{Therefore}\ m_2=3.\\\\\text{We have the equation:}\ y=3x+b.\\\\\text{Put the coorsdinates of the point (2, -5) to the equation of the line}\\\\-5=3(2)+b\\-5=6+b\qquad\text{subtract 6 from both sides}\\-11=b\to b=-11

Simplify. (-5.12) - (-4.7) (7.021)
aksik [14]
First, you should do the product first:
(-4.7)* (7.021)= -32.9987

Then, let's do the subtraction:
(-5.12)- (-32.9987)
= (-5.12)+ 32.9987
= 27.8787

Final answer: 27.8787

Hope this would help~
