Answer 1

Answer:

y = -5x - 10

Step-by-step explanation:

Slope-intercept form: y = mx + b

m = slope

b = y-intercept

Now, in your case:

5x + y = -10

Move 5x (don't forget to change the signs!):

y = -5x - 10

-2x + 4 < 16
Help me please I didn’t pay attention

Answers

Answer:

I think it’s done like this, I’m not sure

First, collect the like terms

-2x<16-4

-2x<12

x<12/-2

x<-6

So, you substitute -6 instead of x to find which is greater

12+4<16

16<16

Which makes it false

Step-by-step explanation:

I hope I explained well, please give me brainliest

The solution of the inequality - 2x + 4 < 16 will be;

⇒ - 6 < x

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The inequality is,

⇒ - 2x + 4 < 16

Now,

Solve the expression as;

⇒ - 2x + 4 < 16

Subtract 4 both side, we get;

⇒ - 2x + 4 - 4 < 16 - 4

⇒ - 2x < 12

Divide by 2 , we get;

⇒ - x < 6

Multiply by - 1, we get;

⇒ x > - 6

⇒ - 6 < x

Thus, The solution of the inequality - 2x + 4 < 16 will be;

⇒ - 6 < x

twice the sum of k and 9 is 4

Answers

Answer:

2(k + 9) = 4

Step-by-step explanation:

Use distributive property.

2 x k = 2k

2 x 9 = 18

Equation:

2k + 18 = 4

Subtract 18 from both sides

2k = -14

Divide both sides by 2

k = -7

Answer:

-7

Step-by-step explanation:

First, we need to write this an equation

2(k+9)=4

2k+18=4

-18       -18

2k=-14

You are at a fruit stand to get some fresh produce. You notice that the person in front of you gets 5
apples and 4 pears for 10 dollars. You get 5 apples and 5 pears for 11 dollars. Write a system of
equations that could be used to find the price of an apple and the price of a pear.

Answers

Answer:

[tex]5A + 4P = 10[/tex]

[tex]5A + 5P = 11[/tex]

1 apple costs $1.2

1 pear costs $1

Step-by-step explanation:

Represent Apples with A and Pears with P

For the person in my front, the expression is:

[tex]5A + 4P = 10[/tex]

For me, the expression is

[tex]5A + 5P = 11[/tex]

Hence, the system of equation is:

[tex]5A + 4P = 10[/tex]

[tex]5A + 5P = 11[/tex]

Solving for the values of A and P.

Substract equation (2) from (1)

[tex]5A - 5A + 4P - 5P = 10 - 11[/tex]

[tex]-P = -1[/tex]

[tex]P = 1[/tex]

Hence, 1 pear costs $1

Substitute 1 for P in [tex]5A + 4P = 10[/tex]

[tex]5A + 4 * 1 = 10[/tex]

[tex]5A + 4 = 10[/tex]

[tex]5A = 10 - 4[/tex]

[tex]5A = 6[/tex]

[tex]A = \frac{6}{5}[/tex]

[tex]A = \$1.2[/tex]

Hence, 1 apple costs $1.2

What is the slope of the line that passes through (1, 4) and (-3, -3)?

Answers

Answer:

y=7/4x+9/4

Step-by-step explanation:

You want to find the equation for a line that passes through the two points:

(1,4) and (-3,-3).

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

First, let's find what m is, the slope of the line...

The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.

For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:

So what we need now are the two points you gave that the line passes through. Let's call the first point you gave, (1, 4), point #1, so the x and y numbers given will be called [tex]x_1[/tex] and [tex]y_1[/tex]. Or,

Also, let's call the second point you gave, (-3,-3), point #2, so the x and y numbers here will be called [tex]x_2[/tex] and [tex]y_2[/tex]. Or,

Now, just plug the numbers into the formula for m above, like this:

m=  

[tex]\frac{-3-4}{-3-1}[/tex]

m= 7/4

So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this:

y=7/4x+b

Now, what about b, the y-intercept?

To find b, think about what your (x,y) points mean:

(1,4). When x of the line is 1, y of the line must be 4.

(-3,-3). When x of the line is -3, y of the line must be -3.

Because you said the line passes through each one of these two points, right?

Now, look at our line's equation so far: y=7/4x+b. b is what we want, the 7/4 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specifically passes through the two points (1,4) and (-3,-3).

So, why not plug in for x and y from one of our (x,y) points that we know the line passes through? This will allow us to solve for b for the particular line that passes through the two points you gave!.

You can use either (x,y) point you want..the answer will be the same:

(1,4). y=mx+b or 4=7/4 × 1+b, or solving for b: b=4-(7/4)(1). b=9/4.

(-3,-3). y=mx+b or -3=7/4 × -3+b, or solving for b: b=-3-(7/4)(-3). b=9/4.

See! In both cases we got the same value for b. And this completes our problem.

The equation of the line that passes through the points

(1,4) and (-3,-3)

is

y=7/4x+9/4

Find the slope of each of the two lines using the formula

y1-y2/x1-x2

Then if the slopes are the same, they’re parallel, and if they are the opposite reciprocal they are perpendicular. If they aren’t either of those options then it’s neither

Let me know if this helped!

9514 1404 393

Answer:

  21.  perpendicular

  22.  neither

  23.  parallel

Step-by-step explanation:

It can help to plot the points on a graph and draw lines through them. This can also let you count grid squares, which can make it easier to find the slope.

21. See attachment 1. The lines are perpendicular.

QR has a slope of -3/2. ST has a slope of 2/3, the opposite reciprocal.

__

22. See attachment 2. The lines are neither parallel nor perpendicular.

__

23. The x-coordinates of Q and R are the same, so this is a vertical line at x=-1. The x-coordinates of S and T are also the same, so it is a vertical line at x=11. The two vertical lines are parallel to each other.

Additional comment

When you have a number of problems that all require similar arithmetic, it can be useful to embed that arithmetic in a spreadsheet. You have to enter the numbers somewhere to "show work" or perform a calculation, so you may as well enter them into a spreadsheet that does the calculation for you.

Of course, the slope formula is ...

  m = (y2 -y1)/(x2 -x1)

If you simply show the values of m for each pair of points, you can see if they are equal (lines are parallel). You can also have the spreadsheet compute their product to see if it is -1 (lines are perpendicular). If you get a #DIV/0! error, it means the line is vertical (and the product will also give an error). You can avoid error messages by making the spreadsheet more sophisticated, but that isn't necessary for the purpose here.

Transform the equation.
Shift y=5√x+5 horizontally, 5 units to the right and a stretch by a factor of 4
What is the transformed equation?

Answers

Answer:

1. I assume that stretching vertically by factor of 2 means that every point on the transformed curve is twice as far from the x axis as the original curve.

Imagine that you have plotted y=5x.  you want to change the y scale so that each point on the original curve is two times as high.  For example, one point on the original curve is (1,5).  This point must be relocated to (1,10).  Similarly, the point (2,10) on the original curve must be relocated to (2,20).

You can see that these relocations are accomplished if we transform the function to y=2(5x)=10x.
