{x | x R, x ≤ -1}

Answer:

Solving the linear equation [tex]3(-4x + 5) = 12[/tex] we get [tex]\mathbf{x=\frac{1}{4}}[/tex]

Step-by-step explanation:

We need to solve to find the value for x in the linear equation: [tex]3(-4x + 5) = 12[/tex]

1. Use the distributive property:

Multiply 3 with terms inside the bracket

[tex]3(-4x + 5) = 12\\3(-4x)+3(5)=12\\-12x+15=12[/tex]

2. Use the subtraction property of equality:

Subtracting 15 on both sides

[tex]-12x+15-15=12-15\\-12x=-3[/tex]

3. Division property of equality:

Divide both sides by -12

[tex]\frac{-12x}{-12}=\frac{-3}{-12}[/tex]

[tex]x=\frac{1}{4}[/tex]

So, solving the linear equation [tex]3(-4x + 5) = 12[/tex] we get [tex]\mathbf{x=\frac{1}{4}}[/tex]

Answer:

x= [tex]\frac{1}{4}[/tex]

Answer:

1 pound of apple costs $2.50

1 pound of strawberries costs $1.25

Step-by-step explanation:

System of Equations

Let's define the following variables:

x = cost of 1 pound of apples

y = cost of 1 pound of strawberries

.........................................

Marcus purchased 3 pounds of apples and 4 pounds of strawberries for a total of $12.50. Thus:

3x + 4y = 12.50       [1]

Shannon purchased 5 pounds of apples and 1 pound of strawberries for a total of $13.75, thus:

5x + y = 13.75       [2]

We need to solve the system of the equations [1] and [2].

Solving for y in [2]:

y = 13.75 - 5x       [3]

Substituting in [1]

3x + 4(13.75 - 5x) = 12.50

Operating:

3x + 55 - 20x = 12.50

-17x = -55 + 12.50 = -42.50

Dividing by -17:

x = -42.50/(-17)

x = 2.5

Substituting in [3]:

y = 13.75 - 5*2.5

y = 1.25

Solution:

1 pound of apple costs $2.50

1 pound of strawberries costs $1.25

Answer:

(- 4, - 10 )

Step-by-step explanation:

Given the 2 equations

- 10x + 2y = 20 → (1)

y = 3x + 2 → (2)

Substitute y  3x + 2 into (1)

- 10x + 2(3x + 2) = 20 ← distribute parenthesis and simplify left side

- 10x + 6x + 4 = 20

- 4x + 4 = 20 ( subtract 4 from both sides )

- 4x = 16 ( divide both sides by - 4 )

x = - 4

Substitute x = - 4 into (2) for corresponding value of y

y = 3(- 4) + 2 = - 12 + 2 = - 10

solution is (- 4, - 10 )

Answer:

x=$7

Step-by-step explanation:

The total cost of bill is $32, $11 is from a plate of corn tacos. And there are 3 purchased burrito bowls at a cost of $x each.

$32 (total bill)

-$11 (tacos)

=$21

$21 / 3 (burrito bowls)

=$7

x or the cost of each burrito bowl is $7

Step-by-step explanation:

Answer:

a/b = 2

so , a = 2b

b/c = 3/4

so , c = 4b/3

c/a = (4b/3) / 2b

which gives 2/3

Step-by-step explanation:

Step-by-step explanation:

[tex] \frac{b}{c} = \frac{3}{4} \\ 3c = 4b \\ c = \frac{4b}{3} [/tex]

[tex] \frac{a}{c} = 2 \\ a = 2b[/tex]

Answer:

y=2

Step-by-step explanation:

horizontal lines are y= the y intercept

if you want the line to go through the point (-2,2) it would be y=2 because points are written as (x,y)

the line y=2 would cross through the y access at 2 and also cross through every other point that is (x,2)

Answer:

C

Step-by-step explanation:

Once

[tex]\sqrt{xy} = 6[/tex]

We know that [tex]xy = 36[/tex]

There are infinity values for [tex]x, y[/tex], but considering [tex]x, y \in \mathbb{Z}[/tex]

Below we have all the solutions for [tex]x, y[/tex]

Negative:

[tex]\\x = -36 \text{ and } y = -1\\x = -18 \text{ and } y = -2\\x = -12 \text{ and } y = -3\\x = -9 \text{ and } y = -4\\x = -6 \text{ and } y = -6\\x = -4 \text{ and } y = -9\\x = -3 \text{ and } y = -12\\x = -2 \text{ and } y = -18\\x = -1 \text{ and } y = -36\\[/tex]

Positives:

[tex]x = 36 \text{ and } y = 1\\x = 18 \text{ and } y = 2\\x = 12 \text{ and } y = 3\\x = 9 \text{ and } y = 4\\x = 6 \text{ and } y = 6\\x = 4 \text{ and } y = 9\\x = 3 \text{ and } y = 12\\x = 2 \text{ and } y = 18\\x = 1 \text{ and } y = 36\\[/tex]

We can see that [tex]x + y \neq 18[/tex]

Step-by-step explanation:

The area of the circular opening is  201.14 sq.inches.

Area is the space occupied by any given surface in a two dimensional plane.

A circular duct has a diameter of 16 inches

Area of the circular opening is given by

πd²/4

d is the diameter of the circle

= (22/7) * (16)²/4

= 201.14 sq.inches

Therefore the area of the circular opening is  201.14 sq.inches.

Answer:

The answer is the third option 2 pounds cost a total of 12$.

Step-by-step explanation:

With the way the graph is working makes 2 pounds a total of 12$.

The ordered pair (2, 12) indicates that 2 pounds of Swiss cheese cost a total of $12.00. which is the correct answer would be an option (C).

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The provided graph shows the relationship between the total price of the sliced Swiss cheese in dollars, y, and the weight of Swiss cheese in pounds, x.

This can be determined by looking at the graph and finding the point on the graph that corresponds to the ordered pair (2, 12).

From the graph, it can be seen that point (2, 12) lies on the line representing the total cost of Swiss cheese.

This means that the y-coordinate, 12, represents the total cost in dollars of the Swiss cheese, and the x-coordinate, 2, represents the amount of Swiss cheese in pounds.

Therefore, the ordered pair (2, 12) shows that the price of 2 pounds of Swiss cheese was $12.00.

Answer:

You need to give us the answers

Step-by-step explanation:

Answer:

The first step would be to plot the y-intercept. In this equation, the y-intercept is 5. The ordered pair is (0, 5), because (x, y).

You go up 5 from the origin (the center of the graph, (0, 0) ), and plant a dot on the y-axis.
