x−1

first, draw the graph for equations y=2x+1 and y=

x−1

for y=2x+1

substitute y=0 we get, 2x+1=0⟹x=−0.5

substitute x=0 we get, y=1

therefore, y=2x+1 line passes through (0.5,0) and (0,1) as shown in fig.

Hence, y≥2x+1 includes the region above the line.

for y=

x−1

substitute y=0 we get,

x−1=0⟹x=2

substitute x=0 we get, y=−1

therefore, y=2x+1 line passes through (2,0) and (0,-1) as shown in fig.

Hence, y>

x−1 includes the region above the line.

the intersection region is the shaded region as shown in above figure which includes I, II and III quadrants.

Point R is the midpoint of KL. If KR = 7x - 10 and RL = 3x + 34, find KL.

Answers

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

R is the midpoint of KL ;

Thus R bisects KL , which means :

[tex]KR = RL[/tex]

So :

[tex]7x - 10 = 3x + 34[/tex]

Add sides 10

[tex]7x - 10 + 10 = 3x + 34 + 10 \\ [/tex]

[tex]7x = 3x + 44[/tex]

Subtract sides 3x

[tex] - 3x + 7x = - 3x + 3x + 44[/tex]

[tex]4x = 44[/tex]

Divide sides by 4

[tex] \frac{4x}{4} = \frac{44}{4} \\ [/tex]

[tex]x = 11[/tex]

_________________________________

[tex]KL = KR + RL[/tex]

[tex]KL = (7x - 10) + (3x + 34)[/tex]

[tex]KL = (7 \times 11 - 10) + (3 \times 11 + 34) \\ [/tex]

[tex]KL = (77 - 10) + (33 + 34)[/tex]

[tex]KL = (67) + (67)[/tex]

[tex]KL = 60 + 7 + 60 + 7[/tex]

[tex]KL = 60 + 60 + 7 + 7[/tex]

[tex]KL = 120 + 14[/tex]

[tex]KL = 134[/tex]

Explanation:

First you need to find the area of the triangle. To do that you do BH*0.5
So- 8*6*.5
And you get- 24
So if the area of of the rectangle is 5 times the size of the area of the triangle then you do 5*24 and get 120
And since we know 12 is one of the sides and to find area of a rectangle u do L*W, all you would do is 120/12 and you get 10

Here is a system of equations. y=2x-1 y=-x-4 Graph the system. Then write its solution. Note that you can also answer "No solution" or "Infinitely many" solutions.​

Answers

Answer:

The solution of the given system is: (-1,-3)

Step-by-step explanation:

Given equations are:

[tex]y = 2x-1\\y = -x-4[/tex]

Solving a system using graph means plotting the lines represented by the system of equations and then finding out where the lines intersect. If the lines intersect at only one point, that point is solution of the system.

We have used the online graphing calculator "Desmos" plot the lines.

Manually, the points can be obtained by substituting values of x in both equations

In the attached picture, the red line represents the first equation and the blue line represents the second. Both lines intersect at (-1,-3)

Find the final sale price of a basketball that is $ 35 which is on sale for 50% and then gets an additional 10% off.

Answers

Answer:

$15.75

Step-by-step explanation:

$35 * 0.50 = 17.5

$35 - $17.50 = $17.50

$17.50 * 0.10 = $1.75

$17.50 - $1.75 =$15.75

Answer:

$15.75

Step-by-step explanation:

To find the percent of a number, we need to express the percent as a decimal with the decimal point of the original percent moved two places to the left. We cannot add the two percents together. You are only paying 50% of the original price.

50% = 0.5

We will now move to decimal two places to the left.

0.005 x 35 = 17.50

Now, we find 90% (since we only care about the amount you are paying) of $17.50

0.009 x 17.50 = 15.75

$15.75

Determine the domain and range of the function shown in the graph.

Answers

Answer:

The domain and range of the function shown in the graph will be:

{x|x ≥ -4}; {y|y ≥ 2}

Thus, option 2 is true.

Step-by-step explanation:

We know that domain is the set of all possible values for which is the function is defined.

First, let's check the domain. We see a closed circle at x = -4 and the graph is heading towards +ve infinity i.e. [-4, ∞).

A closed circle means the point is included in the domain.

Therefore, the domain is:

{x|x ≥ -4}

We know that the range is the set of values of the dependent variable for which a function is defined.

Now, let's check the range. We see a closed circle at y = 2 and the y-values of the graph are heading towards +ve infinity. i.e. [2, ∞)

Therefore, the range is:

{y|y ≥ 2}

Hence, the domain and range of the function shown in the graph will be:

{x|x ≥ -4}; {y|y ≥ 2}

Thus, option 2 is true.

The measure of the angle is 44 times greater than its supplement.
What is the measure of the​ supplement?

Answers

Answer: The measure of it's supplement is 4°

Step-by-step explanation:

If an angle is 44 times is supplement, then we can represent it by the equation   x = 44y    where  x is the angle and y is it's supplement.

Supplementary angles add up to 180 degrees, meaning that  x + y = 180.

  x = 44y  

x + y = 180  

Using both equations substitute the value for x in the first equation, into the second equation and solve for y.

 

44y + y = 180           Combine like terms on the left side

   45y = 180        Divide both sides   45

 y = 4  

This means the measure of it's supplement is 4 degrees.

Now input 4 into one of the equations for  y and solve for x to find the main angle.

x = 44(4)

x = 176  

This also means that the angle itself is 176 degrees.

The measure of the supplementary angle is 4°.

It is given that the measure of the angle is 44 times greater than its supplement.

We have to find out the measure of the supplement.

What are supplementary angles ?

Two angles are said to be supplementary angles if the sum of two angles is 180°.

As per the question ;

The measure of the angle is 44 times greater than its supplement.

Let's assume the supplementary angle is x .

So,

The other angle will be 44 × x .

We know that sum of two angles if they are supplementary is 180°.

⇒ x + 44 x = 180 °

⇒ 45 x = 180°

⇒ x = 180 ÷ 45

⇒ x = 4°

And the other angle will be ;

= 44 × 4

= 176°

Thus , the measure of the supplementary angle is 4°.

An investor flips a house, selling it for $88,000. If her profit was 30%, how much did she pay for the house originally? Round to two decimal places.

Answers

Answer:

She paid $67692.31 for the house originally.

Step-by-step explanation:

Let the initial cost of the house be [tex]x[/tex] dollars.

Given:

Selling price of the house (S.P) = $88000

Profit made = 30% of 'x' = [tex]0.30x[/tex]

We know that,

Profit = Selling Price - Original price

[tex]0.30x = 88000 - x[/tex]

Adding [tex]x[/tex] on both sides, we get:

[tex]0.30x+x = 88000\\\\1.3x=88000[/tex]

Dividing both sides by 1.3, we get:

[tex]x = 88000/1.3\\\\x = \$ 67692.307[/tex]

Rounding to 2 decimal places, we get:

[tex]x=\$67692.31[/tex]

Therefore, she paid $67692.31 for the house originally.
