  • Left to Right<u> </u>

<u>Algebra I</u>

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 2x - 5

f(x) = 15

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute in f(x) [Function]:                                                                             15 = 2x - 5
  2. [Addition Property of Equality] Add 5 on both sides:                                    20 = 2x
  3. [Division Property of Equality] Divide 2 on both sides:                                  10 = x
  4. Rewrite:                                                                                                             x = 10

A movie theater is located on a map of a city represented by a coordinate plane. The location of the movie theater is at (−4, 2)
Romashka [77]

See the graph

<h2>Explanation:</h2>

Remember to write complete questions in order to get good and exact answers. Here you haven't provided any option, but it's easy to plot this point on a coordinate system in order to know the location of the movie theater. We know that this theater is at the point:

(-4,2)

So let's plot this point in the cartesian plane:

  • The x-coordinate is -4
  • The y-coordinate is 2.

So the graph is shown below. Remember that the horizontal axis is called the x-axis while the vertical axis is called the y-axis.

  • x > 0 for the x-values to the right of the origin.
  • x < 0 for the x-values to the left of the origin.
  • y > 0 for the y-values above the origin
  • y < 0 for the y-values below the origin.

Michelle has $8 and wants to buy a combination of dog food to feed at least two dogs at the animal shelter. A serving of dry foo
Ghella [55]

Answer:

PART A: Inequality (a)

Solve for y

The graph of y ≥ ⅓(8-x) is represented by the upper red line and all points in the shaded area below it. The line is solid because points on the line satisfy the conditions.

 Inequality (b)

Solve for y

The graph of y ≥ 2 - x is represented by the lower blue line and all points in the shaded area above it. The line is solid because points on the line satisfy the conditions. The solution lies in the purple area. It consists of all combinations of x and y that make y ≥ ⅓(8 - x) and y ≥ 2 - x. A practical but not a mathematical condition is that all values of x and y must be zero or positive numbers (for example, you can't have -2 servings of food), so I have plotted only the numbers in the first quadrant.

PART B: If a point is a solution of the system, then the point must satisfy both inequalities of the system.

For x=8, y=2. Verify inequality A  is not true. So the point does not satisfy inequality A. Therefore, the point is not included in the solution area for the system.

PART C: I choose the point (3,1) which is included in the solution area for the system.

That means Michelle buys 3 serves of dry food and 1 serving of wet food.

For fun, if X=180 and Y=20 then what is (Y-X)x(53-33)+3,269= ???? For fun
Masja [62]

Answer:

6,469!

Step-by-step explanation:

180-20=160

53-33=20

160*20=3,200

3,269+3,200=6,469
