X=1-2y how would you solve this?
Ivahew [28]

Answer:

You can't have a single answer.

Step-by-step explanation:

An indiviual equation can't be solved if it has 2 variables.

You can, however, graph it.

The line will create all the possible sets of answers for the problem.

*Remember solutions are found in the shaded area or on a solid line (points on a dashed line are not a solution).
Irina-Kira [14]

The solutions for the inequality are -

  • (3, 3)
  • (7, 7)
  • (10, 10)

<h3>What is the general equation of a Straight line? What is linear inequality?</h3>

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

A inequality is used to compare two or more expressions. The straight line inequalities are of the form -

y > mx + c

y < mx + c

y ≥ mx + c

y ≤ mx + c

We have the following inequality -

x + 3y > 6

We can write -

x + 3y > 6

3y > - x + 6

y > (-1/3)x + 2

Refer to the graph of the inequality attached. The plotted points in the shaded region represent the solutions for the inequality. We can write -

  • (3, 3)
  • (7, 7)
  • (10, 10)

Therefore, the solutions for the inequality are -

  • (3, 3)
  • (7, 7)
  • (10, 10)

One package of tile will cover 3 square feet.How many packages will shee need 8,13,15,39
IrinaVladis [17]

Hey there! :)

Answer:

13 packages.

Step-by-step explanation:

Begin by finding the total area of this composite figure. Separate the figure into separate rectangles. Use the formula A = l × w to calculate the area of each:

Smaller rectangle:

Subtract 7 from 9 to find the width:

9 -7 = 2. Therefore:

2 × 2 = 4 ft².

Larger rectangle:

7 × 5 = 35 ft².

Add up the two areas to find the area of the entire figure:

4 + 35 = 39 ft².

If each package of tile covers 3 ft², simply divide to find the package of tiles needed:

39 / 3 = 13 packages.
