Soue se compound inequality and give your answer in intentel notation- 10 AND-80-72-1

Answers

S= (-4, 1 ]

1) Solving that compounded inequality

4x +6 > -10 and -8x+7 ≥ -1

2) Let's start by 4x +6 > -10

4x +6 > -10 Subtracting 6 from both sides

4x > -10-6

4x > -16 Dividing both sides by 4

x > -4

And with -8x+7 ≥ -1

-8x+7 ≥ -1 Subtract 7 from both sides

-8x ≥ -1 -7

-8x ≥ -8 Multiply by -1

8x ≤ 8

x ≤ 1

3) Graphing the solution interval:

So the solution is the interval S= (-4, 1 ] not including x= -4 and including the value x = 1

Give the slope and y - intercept for each of the following equations, then sketch the graph. Give the slope ofany line perpendicular to the given line.y =22 +5Slope =y - intercept = (0,_ ) Slope of a Line Perpendicular =

Answers

Answer:

The slope is 2.

The y-intercept is 5 or (0, 5)

See graph below

Explanation:

Given:

y = 2x + 5

To find:

the slope, y-intercept, and plot a graph

To determine the slope and y-intercept, we will use the equation of line formula:

y = mx + b

m = slope

b = y-intercept

Comparing both equations:

y = y

2x = mx

m = 2

The slope = 2

5 = b

The y-intercept = 5

To plot the graph, we will assign values to x in order to get values to y that will be plotted:

let x = -4, 0, 4

when x = -4

y = 2(-4) + 5 = -3

when x = 0

y = 2(0) + 5 = 5

when x = 4

y = 2(4) + 5 = 13

Plotting the points:

EXPLANATION:

Given:

To find:

The domain and the range

Recall that the domain of a function is the set of possible input values for which the function is defined.

To determine the domain of a function from a graph, we consider the possible x-values from left to right.

So the domain of the given function can be written as;

[tex]Domain:(-5,-4]\cup[-1,2][/tex]

The range of a function is the set of possible output values.

To determine the range of a function from a graph, we consider the possible y-values from the bottom to the top.

So the range of the given function can be written as;

Answers

At the airport, the new runway will be parallel to a nearby highway. The equation that represents the highway is 6y = 8x - 11. Which equation could represent the new runway?



A. 9y = 12x + 5

B. 9x = 12y + 8

C. 12y = -9x + 2

D. 12x = -9y + 4

______________________________________________________

Parallel equations have the same slope

6y = 8x - 11

y= 8/6 x - 11/6

y= 4/3 x-11/6

y = m x +b (m is the slope )

_____________________________________________

You need to find the other equation with the same slope

____________________________

A. 9y = 12x + 5

y = 12/ 9 x + 5/9

y = 4/3 x + 5/9

_________________________

B. 9x = 12y + 8

12 y= 9x-8

y= 9/ 12 x- 8/12

y= 3/4 x - 4/6

discarded

________________________

C. 12y = -9x + 2

y = -9/12 x + 2/12

y = -3/4 x + 1/6

discarded

_________________________

D. 12x = -9y + 4

12x -4 = -9y

y = -12/9 x +4/9

y = -4/3 x+4/9

discarded

_______________

So then, A 9y = 12x + 5 is the equation that could represent the new runway because is parallel to the highway 6y = 8x - 11.

Point S is on line segment \overline{RT} RT . Given RT=3x,RT=3x, RS=3x-5,RS=3x−5, and ST=3x-1,ST=3x−1, determine the numerical length of \overline{RT}. RT .

Answers

The numerical length of the line segment RT is 6.

Length:

Length is the measuring unit used to identifying the size of an object or distance from one point to the other.

Given,

There is a point on the line segment RT.

And the values of the pots are,

RT = 3x, RS = 3x - 5 and ST = 3x - 1.

Now we need to find the length of the line segment RT.

To find the line of the line segment RT,

We have to add the length of the segments,

That can be written as,

=> RT = RS + ST

Now, we have to apply the values of the point to the equation, then we get,

=> 3x = 3x - 5 + 3x - 1

=> 3x = 6x - 6

=> 6x - 3x - 6

=> 3x - 6

=> 3x = 6

=> x = 2

If the value of x is 2, then the length of the line segment RT is,

RT = 3x => 3 x 2 = 6

Therefore, the length of the line segment RT is 6.

5. There are 9.75 ounces of Cinnamon Toast Crunch in a bowl. Additional cereal ispoured into the bowl at a rate of 1.5 ounces per second. How many ounces are inthe bowl after 3 seconds?

Answers

Question:

There are 9.75 ounces of Cinnamon Toast Crunch in a bowl. Additional cereal is poured into the bowl at a rate of 1.5 ounces per second. How many ounces are in the bowl after 3 seconds?

Solution:

If additional cereal is poured into the bowl at a rate of 1.5 ounces per second, then in 3 seconds the additional cereal into the bowl is 1.5x 3 = 4.5 ounces. Thus after 3 seconds, the bowl has the original amount that it already had and the new aggregate:

9.75 ounces + 4.5 ounces = 14.25

then, the correct answer is:

14.25

Describe the transformation from the graph of f to the graph of h. Write an equation that represents h in terms of x. Look at image for example. Let’s do problem number 11

Answers

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given functions.

[tex]\begin{gathered} f(x)=-(x+5)^2-6 \\ h(x)=\frac{1}{3}f(x) \end{gathered}[/tex]

STEP 2: Explain the transformation that occurs

What are Vertical Stretches and Shrinks?

While translations move the x and y intercepts of a base graph, stretches and shrinks effectively pull the base graph outward or compress the base graph inward, changing the overall dimensions of the base graph without altering its shape. When a graph is stretched or shrunk vertically, the x -intercepts act as anchors and do not change under the transformation.

This can be explained further as:

For the base function f (x) and a constant k > 0, the function given by:

[tex]\begin{gathered} h(x)=k\cdot f(x) \\ A\text{ vertical shrinking of f\lparen x\rparen by k factor where }0Calculate the equation that represents h in terms of x[tex]\begin{gathered} f(x)=-(x+5)^2-6 \\ h(x)=\frac{1}{3}\cdot f(x)=\frac{1}{3}\cdot-(x+5)^2-6 \end{gathered}[/tex]

Hence, the transformation from the graph is a vertical shrinking by 1/3 factor and the equation that represents h in terms of x is given as:

Answers

We will assume the next table to answer this question (a linear function) (since the data in the question is not clear):

Having this information, we can find the slope using the formula for it:

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

If we pick up from the table the next points:

x1 = 1, y1 =6

x2 = 2, y2 = 8

Then

[tex]m=\frac{8-6}{2-1}=\frac{2}{1}\Rightarrow m=2[/tex]

We can use the slope-point formula to find the y-intercept. We can use the point (3, 10). Then, we have:

[tex]y-y_1=m\cdot(x-x_1)\Rightarrow y-10=2\cdot(x-3)\Rightarrow y-10=2x-6[/tex][tex]y=2x-6+10\Rightarrow y=2x+4[/tex]

We end up with the slope-intercept formula for the line. Then the y-intercept is 4. In other words, if we have x = 0, then y = 4.

Then the slope for the values represented in the proposed table is m = 2, and the y-intercept is y = 4.

In the rhombus m<1 = 160 what are m<2 and m<3. This diagram is not drawn to scale. Show all work

Answers

We are given a rhombus shape.

The measure of angle ∠1 = 160°

Recall that in a rhombus, the oppsite angles are equal, this means ∠1 = ∠2

So, ∠2 = 160°

Recall that the sum of all four interior angles in a rhombus must be equal to 360°

The diagonal line divides the angles in half.

This means that angle 3 and angle x are equal.

[tex]\begin{gathered} 160\degree+160\degree+2(\angle3+x)=360\degree_{} \\ 320\degree+2(\angle3+x)=360\degree \\ 2(\angle3+x)=360\degree-320\degree \\ 2(\angle3+x)=40\degree \\ \angle3+x=\frac{40\degree}{2} \\ \angle3+x=20\degree \end{gathered}[/tex]

Since we know that ∠3 and ∠x are equal then

∠3 = 10° and ∠x = 10°

Therefore,

∠2 = 160°

∠3 = 10°
