Can you write a linear inequality whose solution contains only points with positive x-values and y-values? why or why not?

Answers

No, you can not. So a linear inequality would be an infinitely long straight line on a math graph. Having a solution contains only positive x, y value would mean that your line cannot exceed the first quadrant of the graph. Try to draw an infinite long straight line, only within the first quadrant, clearly, you can not.
Final answer:

Yes, a linear inequality can be written whose solution contains only points with positive x-values and y-values.

Explanation:

A linear inequality is a mathematical statement that expresses a relationship between two linear expressions using inequality symbols (>, <, ≥, or ≤). It describes a region of values that satisfy the inequality, often represented on a coordinate plane as a shaded area.

Yes, a linear inequality can be written whose solution contains only points with positive x-values and y-values. One example of such an inequality is y > 0. This inequality represents all the points above the x-axis in the coordinate plane, where both x-values and y-values are positive.

The product of some negative number and 3 less than twice that number is 209. find the number

Answers

the negative number would most likely be -19/2

let the negative number be x,
3 less than twice that negative number would be (2x-3)
hence,
equation form
x multiply by (2x-3) equals to 209
it would result in equation

Chad bought 8 pounds of strawberries for $25.25. What is the cost, c, of 1 pound of strawberries?

Answers

Answer: $3.15625 

In this case, you know that a number of strawberries (8 pounds) and the cost ($25.25). Then to find out how much the cost of 1 pounds strawberry you just need to divide the cost with 8. Since the unit used is all same(all use pounds), you don't need to do any conversion. The calculation would be:
$25.25 / 8 = $3.15625 




Given the system of equations, what is the solution?
x + 2y = 7
x - 2y = -1

(A.) {(-8, -12)}
(B.) {(3, 2)}
(C.) {(-4, 6)}

Answers

We can do the elimination method to find the solution for this problem. The elimination method involves adding the two equations together to get rid of a like term.

x + 2y = 7
+ x - 2y = -1
—————————
2x = 6

Now that we eliminated 2y because they cancel out, we are left with 2x = 6. Divide both sides by 2 in order to get x.

The answer is: x = 3.

Now that we know the numerical value of x, all we have to do is plug x into either system of equation in order to find the numerical value of y.

x + 2y = 7

3 + 2y = 7

2y = 4

y = 2

The solution to the problem is (3, 2).

Final answer:

The solution to the system of equations x + 2y = 7 and x - 2y = -1 is found by eliminating y, yielding x=3 and y=2, which is option B, (3, 2).

Explanation:

The solution to the system of equations x + 2y = 7 and x - 2y = -1 can be found by adding or subtracting the two equations to eliminate one of the variables. By adding the two equations, we eliminate y and get 2x = 6, which results in x = 3. Substituting x = 3 back into either of the original equations yields y = 2. Therefore, the solution to the system is (3, 2), which corresponds to option B.

The cost of a movie ticket is $5. it costs a group of friends $105 to go to the movies. which equation describes the number of people that went to the movies?

Answers

525, I believe. Because each ticket is $5, and in total, the tickets were $105. So I multiplied 5 x 105=525. 

Please correct me if I'm wrong.

The equation that describes the number of people that went to the movies could be 5x = 105

What is a solution to a system of equations?

For a solution to be solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs,

So solution to a system is the intersection of all its equation at single point(as we need common point, which is going to be intersection of course)(this can be one or many, or sometimes none)

Given; The cost of a movie ticket is $5. it costs a group of friends $105 to go to the movies.

Each ticket cost is $5,

The tickets were $105.

So, multiplied 5 x 105 = 525.

Let x be the number of people that went to the movies.

So, 105 / 5 = x = 21

OR

5x = 105

Therefore, the equation that describes the number of people that went to the movies could be 5x = 105

Two angles are supplementary. one angle measures 12 degrees less than 5 times the other. find the measure of each angle

Answers

supplementary angles, when added, = 180 degrees

a + b = 180
a = 5b - 12

5b - 12 + b = 180
6b - 12 = 180
6b = 180 + 12
6b = 192
b = 192/6
b = 32 <=== one angle is 32 degrees

a = 5b - 12
a = 5(32) - 12
a = 160 - 12
a = 148 <=== the other angle is 148
Final answer:

The measures of the two supplementary angles are 32 degrees and 148 degrees, respectively.

Explanation:

The question is about finding the measures of two supplementary angles given the relationship between them. Supplementary angles are two angles whose measures add up to 180 degrees. If we let x be the measure of the first angle, then the measure of the second angle is 5x - 12 degrees, according to the problem statement.

Since the angles are supplementary, we can set up the following equation: x + (5x - 12) = 180. This simplifies to 6x - 12 = 180. Solving for x gives us x = 32, so the first angle measures 32 degrees.

Substitute x = 32 into the equation for the second angle gives us: 5x - 12 = 5(32) - 12 = 148 degrees. Therefore, the two angles measure 32 degrees and 148 degrees, respectively.

What is m∠D ?

Enter your answer in the box. __°

Answers

check the picture below.

Answer

Find out the m∠D .

To proof

In Δ ABE

∠EAB + ∠ABE + ∠AEB = 180 °

(By using the angle sum property of a triangle.)

As given and shown in the diagram

∠EAB = 14° , ∠ABE = 45 °

Put in the above equation

14° + 45° + ∠AEB = 180 °

∠AEB = 180 °- 59°

∠AEB = 121 °

∠AEB = ∠DEC = 121°

(by using the vertical opposite angles property)

Now in ΔCED

∠DEC + ∠EDC + ∠ECD = 180 °

(Angle sum property of a triangle)

(as given ∠DEC = 121° ,∠ECD = 27° shown in the diagram  )

∠EDC = 180 ° - 27 ° - 121 °

∠EDC  = 32°

therefore

∠ D = 32 °

Hence proved

A right triangle has exterior angles at each of its acute angles with measures in te ratio 13:14. find the measures o the two acute angles of the right triangle.

Answers

The sum of the exterior angles of all polygon is always equal to 360°. The exterior angle sharing the same side with that of the right angle of the triangle is equal to 90°. If the other exterior angles are 13x and 14x then, they add up to 270°. 

The equation that would allow us to determine the values of the angles are,
                          13x + 14x = 270
                              x = 10
The exterior angles are 130 and 140°. The exterior angle and the interior angle always add up to 180°. 

Interior angle 1:   180° - 130° = 50°
Interior angle 2:    180° - 140° = 40°

Therefore, the measures of the two acute angles of the triangle are 50° and 40°.

This is because the answer of said question MUST be greater than 50...

We also know that the question states "the sum of y and 20"

So... that will look like this:

y + 20

We also know that it says "the sum of y and 20 is more than 50", so we set that up like this:

The length of a rectangle is twice its width. if the area of the rectangle is 162 m2 , find its perimeter.

Answers

L = 2W
A = L * W
A = 162

162 = 2W(W)
162 = 2W^2
162/2 = W^2
81 = W^2
sqrt 81 = W
9 = W

L = 2W
L = 2(9)
L = 18

P = 2(L + W)
P = 2(18 + 9)
P = 2(27)
P = 54 <===== perimeter is 54 m
Final answer:

The width of the rectangle is 9m and the length is 18m. The perimeter of the rectangle is 54m.

Explanation:

Let's assume the width of the rectangle as 'w'. According to the given information, the length would be twice the width, so the length can be represented as '2w'.

The formula for the area of a rectangle is length multiplied by width, which can be written as 'A = lw', where 'A' is the area. By substituting the given area value of 162m2, the equation becomes '162 = 2w * w'.

Solving this equation, we get 'w = 9m' which represents the width. The length can be found by doubling the width, so the length is '2 * 9m = 18m'.

The perimeter of a rectangle can be calculated using the formula 'P = 2(l + w)', where 'P' is the perimeter, 'l' is the length, and 'w' is the width. Plugging in the values, the perimeter of the rectangle is 'P = 2(18m + 9m) = 54m'.

First write it in vertex form :-

y= a(x - 2)^2 + 3    where a is some constant.

We can find the value of a  by substituting the point (0.0) into the equation:-

0  = a((-2)^2 + 3

4a = -3

a = -3/4

so our equation becomes  y =  (-3/4)(x - 2)^2 + 3




The required equation is  y =  (-3/4)(x - 2)² + 3 that represents given parabola.

What is Parabola?

A parabola is a U-shaped curve this is drawn for a quadratic function,

f(x) = ax² + b x + c.

The parabola equation into the vertex form:

(y-k) = a(x-h)²

Where (h,k) are the x and y-coordinates of the vertex.

The parabola has vertex (2, 3) which is given in the question

Here h = 2,and  k = 3

Substitute the values of h = 2 and  k = 3 in the above equation

y - 3 = a(x - 2)²

y = a(x - 2)² + 3

If the parabola contains the point (0, 0)

Substitute the point (0, 0) in the above equation

0  = a((-2)² + 3

4a = -3

a = -3/4

Thus, the equation becomes y =  (-3/4)(x - 2)² + 3

Hence, the required equation is  y =  (-3/4)(x - 2)² + 3 that represents given parabola.
