What is the equation of the line in the graph? explanation, please.
A. y = –1/3x – 1
B. y = 7/3x + 5
C. y = –5x + 7
D. y = –1/2x – 7

Answers

B.

The first thing I do with a line is sub in 0 for x. This will give you the y intercept. On the graph, we can see that the y intercept is (0,5). So, the equation we use has to have an output of 5 if we plug in 0. The only one this applies to is equation B.

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

1. Find the maximum and minimum values of z = 2x + 3y subject to the following constraints
[tex]0 \leqslant x \leqslant 7[/tex]
[tex]y \geqslant 1[/tex]
[tex]2x - y \geqslant - 5[/tex]
[tex]x + y \leqslant 11[/tex]
Copy and paste the text below and put your answers into the blanks. maximum value =
when x =
and y =
minimum value =
when x =
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)

what is g in this problem 4-(9g-5)=-18

Answers

Step-by-step explanation:

Let's solve your equation step-by-step.

4−(9g−5)=−18

Step 1: Simplify both sides of the equation.

4−(9g−5)=−18

4+−1(9g−5)=−18(Distribute the Negative Sign)

4+−1(9g)+(−1)(−5)=−18

4+−9g+5=−18

(−9g)+(4+5)=−18(Combine Like Terms)

−9g+9=−18

Step 2: Subtract 9 from both sides.

−9g+9−9=−18−9

−9g=−27

Step 3: Divide both sides by -9.

−9g−9=−27−9

g=3

g = 3
