The solution to the system of inequalities y > -2x+7, y ≤ 3x-8 is the set of points ( (x,y) pairs ) in the intersection of the regions these inequalities are true for, as shown in the graph by the intersection of the blue and red colors.

When mathematical expressions are compared, with non-strict equality, then such mathematical statements are called mathematical inequalties.

A collection of inequalities for which we consider common solution for all inequalities is called a system of inequalities.

Suppose there is inequality given as: y ≥ f(x)

The region it covers is the region of value pairs (x,y) for which this inequality holds true.

We've to draw the region covered by it.

For a function y = f(x), there is y > f(x) on one side of the graph of the function y = f(x) in XY plane, and on other side there is y < f(x).

We just need to figure out this fact at 1 point on either side of the graph of the function y = f(x) , and then the area where y > f(x) is true, along with the curve of the function y = f(x) is included in the region covered by inequality y ≥ f(x)

For this case, the inequalities given are:

y > -2x+7, y ≤ 3x-8

Their solution is the points lying in the intersection of the regions these inequalities are true for, as shown in the graph by the intersection of the blue and red colors.

Answer:

i think there was a discount of 40

Step-by-step explanation:

Answer:

The answer is: 40% Off Discount

Step-by-step explanation:

$100 - $60 = 40%

Hence, 440 cupcakes were sold on that day.

The bakery sold a total of 400 cupcakes that day, with 224 of them being chocolate cupcakes, representing 56 precent of the total.

Use the concept of percentage defined as:

A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred.

Given that,

A bakery sold 224 chocolate cupcakes in a day.

The 224 chocolate cupcakes represent 56% of the total number of cupcakes sold that day.

To find the total number of cupcakes sold,

Use the percentage given and some simple math.

If 56% of the cupcakes sold were chocolate cupcakes and that amounts to 224 cupcakes,

Set up the following equation:

0.56 x Total number of cupcakes = 224 cupcakes

To find the total number of cupcakes,

Divide both sides of the equation by 0.56:

Total number of cupcakes = 224 cupcakes / 0.56

Calculating this,

The bakery sold a total of 400 cupcakes that day.

Answer:

The answer is 105 degrees

Step-by-step explanation:

Z + 43 = a straight line which needs to equal 180 degrees.

Z = 180 - 43 = 137

answer: z = 137 degrees

Answer:

so we know that 43 and y are congruent so y = 43.

we also know that y + x has to equal 180

so

180 - 43 = 137

so x is 137. We also know that z and x are congruent, so therefore z is 137.

Using the z-distribution, as we are working with a proportion, the 99% confidence interval is given by:

a) (0.733, 0.927).

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

In this problem, we have a 99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.

The other parameters are p = 0.83, n = 100, hence the bounds of the interval are given as follows.

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.83 - 2.575\sqrt{\frac{0.83(0.17)}{100}} = 0.733[/tex]

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.83 + 2.575\sqrt{\frac{0.83(0.17)}{100}} = 0.927[/tex]

Hence option a is correct.

Answer:

C. √147

Step-by-step explanation:

Set the values of the triangle up in the Pythagorean Theorem.

a² + b² = c²

x² + 7² = 14²

Take 7 and 14 to the power of 2.

x² + 49 = 196

Subtract 49 from both sides.

x² = 147

Take the square root of both sides. There will only be one answer since lengths cannot be negative.

x = √147

Answer:

C

Step-by-step explanation:

using Pythagoras' identity in the right triangle.

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 7² = 14²

x² + 49 = 196 ( subtract 49 from both sides )

x² = 147 ( take square root of both sides )

x = [tex]\sqrt{147}[/tex]

[tex]\dashrightarrow \sf \ 13.5[/tex]

Answer:

13.5

Step-by-step explanation:

[tex]3*(7+2)/\sqrt{4}[/tex]

You use PEDMAS - priority of calculation

1) Paranthesis

2) Exponents

3) Divide or Multiple (whichever comes first, reading left to right)

4) Add or Subtract (whichever comes first, reading left to right)

so,

Parenthesis first:

[tex]7+2=9[/tex]

becomes

[tex]3*9/\sqrt{4}[/tex]

No exponents, so we skip this step

Left to right for multiply or divide: first comes multiply.

[tex]3*9 = 27[/tex]

becomes

[tex]27/\sqrt{4}[/tex]

Now, last one is divide:

[tex]27/\sqrt{4} = 27/2 = 13.5[/tex]

Answer:

$1.08

Step-by-step explanation:

Use a system of equations. Let x represent eric's money and y represent erica's money.

x+y=5.40

2x=1/2y

Let's solve for y in the second equation and substitute it into the first.

Double both sides.

4x=y

Substitute

x+4x=5.40

5x=5.40

Divide by 5

x=$1.08

Applying the chord theorem, since chords RS and TU are equal, then the measure of arc RS is: 106°.

The chord theorem states that if two chords in a circle are equal in length, then their corresponding minor arcs will also be equal in measure.

Since chords RS = TU, therefore:

m(RS) = m(TU)

Substitute

8x - 14 = 7x + 1

8x - 7x = 14 + 1

x = 15

m(RS) = 8x - 14

Plug in the value of x

m(RS) = 8(15) - 14

m(RS) = 106°

NF = 16

Step-by-step explanation:

Since N is the incenter of ΔABC then ND = NE = NF

ND = NE ⇔ 6x - 2 = 3x + 7 ⇔ 6x - 3x = 7 + 2 ⇔ 3x = 9 ⇔ x = 3

Now , we calculate ND:

ND = 6(3) - 2 = 18 - 2 = 16

Answer:

The reasoning of Jamie is incorrect

Step-by-step explanation:

No, because in the expression 4(x+1)  you will first need to multiply 4 by x, your result is 4x, and then you multiply 4 by 1, you get 4, so the answer will be 4x+4, as mentioned up in the problem.

Also in the expression 6x-2x+4  ,you will first need to subtract 2x from  6x, your result is 4x ,and then you add 4 , so the answer will be 4x + 4

Finally,we obtain

6x-2x+4 = 4x + 4 and 4(x+1) = 4x + 4

Conclusion:

The reasoning of Jamie is NOT correct.

Answer:

Np Jamie is wrong

Step-by-step explanation:

No, because in the phrase 4(x+1), you must first multiply 4 by x, which gives you 4x, and then multiply 4 by 1 to get 4, giving you 4x+4, also, in the phrase 6x-2x+4, you must subtract 2x from 6x to get 4x, and then add 4 to get 4x + 4x.

Our final solution is:

4(x+1) = 4x + 4 and 6x-2x+4 = 4x + 4
