Explain the steps of graphing 2x + 4≤ 12.

Answer:

This is a proportion

Step-by-step explanation:

Cross multiply:

12 * 20 = 16 * 15

Simplifying:

12 * 20 = 16 * 15

Multiply 12 * 20

240 = 16 * 15

Multiply 16 * 15

240 = 240

Add '-240' to each side of the equation.

240 + -240 = 240 + -240

Combine like terms: 240 + -240 = 0

0 = 240 + -240

Combine like terms: 240 + -240 = 0

0 = 0

Solving

0 = 0

Answer:

4x+6y<=10

Step-by-step explanation:

The linear inequality that describes the graph is 4x+ 6y ≤ 10.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

As, The bold straight line passes through the points (1,1) and (-2, 3).

so, equation of line will be

(y- 1) = (3-1)/ (-2-1) (x-1)

y-1 = 2 / (-3) (x-1)

-3y + 3 = 2x - 2

-3y -2x = -5

If we multiply by 2 both side we get

-6y - 4x = -10

4x+ 6y= 10

So, the required inequality for gray area is 4x+ 6y ≤ 10.

Answer:

12x + 2

Step-by-step explanation:

12 is multiplyed by both the x and the (1/6) since it is outside the equation.

so 12 times x = 12x since we dont know what x is

and 12 times (1/6) = (12/6) = 2

Answer:

If b = 6 and c = 10, the value of an expression is 3.

Step-by-step explanation:

Given the expression

[tex]\frac{5b}{c}[/tex]

We have to evaluate the expression if b = 6 and c = 10.

Important Tip:

In order to evaluate the expression  [tex]\frac{5b}{c}[/tex], all we need to do is to substitute the value of b and c in the expression.

As the expression is

[tex]\frac{5b}{c}[/tex]

substitute b = 6 and c = 10 in the expression

[tex]\frac{5b}{c}=\frac{5\left(6\right)}{10}[/tex]

     [tex]=\frac{30}{10}[/tex]

      [tex]=3[/tex]       ∵ [tex]\frac{30}{10}=3[/tex]

Therefore, if b = 6 and c = 10, the value of an expression is 3.

Answer:

24/36

Step-by-step explanation:

Have a nice day..........

Answer:

C) 23

Step-by-step explanation:

If the computer monitor is 20 inches wide, and 12 inches high, we can solve for the diagonal by using the Pythagorean theorem.

Let a = the width, let b= the height, let c = the diagonal.

a^2 + b^2 = c^2

20^2 +12^2 =c^2

400 + 144 = c^2

544 = c^2

C is approximately equal to 23 inches.

Answer:

[tex]x=18[/tex]

Step-by-step explanation:

By rearranging and multiplying by 6 at the end:

[tex]\frac{1}{2}x - 7 = \frac{1}{3}(x-12)\\\frac{1}{2}-7 = \frac{1}{3}x - 4\\\frac{1}{2}x - \frac{1}{3}x = -4 + 7\\(\frac{3}{6} - \frac{2}{6})x = 3\\\frac{1}{6}x = 3\\x = 3 \cdot 6 = 18[/tex]

Answer:

x=1, y=1.

Step-by-step explanation:

From the second equation:

x = 8 - 7y, so substituting for x in the first equation:

3/8(8 - 7y) + 1/3y = 17/24

3 - 21/8 y + 1/3y = 17/24

1/3y - 21/8y = 17/24 - 3

Multiply through by 24:

8y - 21*3 y = 17 - 72

8y - 63y = -55

-55y = -55

y = 1.

And  substituting for y in the second equation:

x + 7(1) = 8

x = 8 - 7

x =  1.
