Answer:

Step-by-step explanation:

There are two ways to go about solving this problem, depending on your available time and fluency with the topic:

Solve it “properly”, by graphing the inequalities yourself, then comparing your graph to the available options.

Use the test-taking strategies of “ruling out answers that are clearly wrong”, followed by “use enough of what you know about the problem to select the correct answer.

Let’s walk through both, since you should be able to do both, as this problem looks very much like a practice problem for a standardized Algebra 1 test.

So! To graph a linear inequality, the steps include graphing the line, determining what type of line, and determining how it’s shaded, though the order of these steps is only important if you’re doing math in pen, which is a terrible idea.

The first inequality:

What happens to the sign or signs of the coordinates when you reflect a point?
elena55 [62]

Part a: Reflecting a point across the x-axis, changes the sign of the y-coordinate.

Part b: Reflecting a point across the y-axis, changes the sign of the x-coordinate.

Part c: Reflecting a point across both the axes, changes the signs of both the coordinates.

Explanation:

Part a: Reflecting a point across the x-axis

The reflection is a transformation of a figure which represents a flip.

The rule for a reflection over the x -axis is given by

(x, y) \rightarrow(x,-y)

Hence, this represents the change of sign of the y-coordinate.

Thus, Reflecting a point across the x-axis, changes the sign of the y-coordinate.

Part b: Reflecting a point across the y-axis

The rule for a reflection over the y -axis is given by

(x, y) \rightarrow(-x, y)

Hence, this represents the change of sign of the x-coordinate.

Thus, Reflecting a point across the y-axis, changes the sign of the x-coordinate.

Part c: Reflecting a point across both the axes

The rule for a reflection across both the axes is given by

(x, y) \rightarrow(-x, -y)

Hence, this represents the changes the signs of both the coordinates.

Thus, Reflecting a point across both the axes, changes the signs of both the coordinates.

Suppose the equation E = $500 + $7x represents a person's earnings (+) for
Sholpan [36]

Answer:

Option D : $780 is the correct answer.

Step-by-step explanation:

Given expression is:

E = $500 + $7x

We will put all the values of given options to check.

A. Putting 430 in given expression

430 = 500 + 7x

430 - 500 = 7x

-70 = 7x

As the number of items sold cannot be negative, therefore, this option is not correct.

B. 530 = 500 + 7x

530 - 500 = 7x

30 = 7x

x = 4.3 (By dividing both sides by 7)

Which is not a whole number.

C. 680 = 500 + 7x

680 - 500 = 7x

7x = 180

x = 25.71

Which is also not a whole number.

D. 780 = 500 + 7x

780 - 500 = 7x

280 = 7x

7x = 280

x = 40

Which is a whole number.

Hence,

Option D : $780 is the correct answer.

Ignore the stuff underneath I did it in pen and messed up.
Vinil7 [7]
U didn't mess up....
V = pi * r^2 * h....divide both sides by (pi)r^2
V / (pi)r^2 = h

-4(11x+2)=80<br> Solve for x
jek_recluse [69]

Answer: x=-2

Step-by-step explanation:

To solve for x, we want to isolate x.

-4(11x+2)=80         [distribute]

-44x-8=80             [add both sides by 8]

-44x=88                 [divide both sides by -44]

x=-2

Now, we know that x=-2.
