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

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

/2      /2

k=-7

Step-by-step explanation: 14*20.5 is 287 I rounded 287 to 300 and then muttplied 300 by 4 and got 1200 that would be 6 rolls

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.

Answer:

a) [tex]\frac{1}{x^3}[/tex]

b) [tex]\frac{1}{a^2}[/tex]

Step-by-step explanation:

Reciprocal of a number is 1 divided by that number

We need to find reciprocal of x^3 and a^2. To find the reciprocal we will do is: 1 divided by the given number

a) Reciprocal of x^3

[tex]=\frac{1}{x^3}[/tex]

b) Reciprocal of a^2

[tex]=\frac{1}{a^2}[/tex]

Answer: 9.

Step-by-step explanation:  First take 6 and divide it by 2, and then multiply by 3. This gets to the correct answer of 9.

Answer: The answer is 9.

Step-by-step explanation: First I take 6 divided by 2 and then I multiply by 3 to get the correct answer of 9. Or I could show you an equation that looks like this from: 6÷2(1+2) to 3*3=9; therefore, 1 is incorrect answer because it has an order of operations and 9 is the correct answer because it doesn’t have an order of the operations. I hoped this helps you! :D

Answer:

Leslie is NOT correct

Step-by-step explanation:

Leslie thinks that the number closer to 0 that's in the negatives it smaller because the number is smaller. But actually, the number farther from 0 that's in the negatives is smaller. So, -12 °C is warmer than -20 °C

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.

Answer:

y = 3x - 2

Step-by-step explanation:

Step 1: Look at the "y" axis and see what it is going through (-2)

Step 2: Check if the line if a positive slope or a negative slope (positive)

Step 3: Since we now know this is a positive slope, it cancels out "D" and "A".

Step 4: This would not be B because the rise is "1" and the run is "3"

Final Ansr: "C" because the rise is "3" and the run is "1" with a "-2" y-intercept.

Answer:

f(x)=-4x+-2

Step-by-step explanation:

Slope intercept form: f(x)=mx+b

m=slope=[tex]\frac{rise}{run}[/tex]

b=y-intercept=y value when x=0

Step-by-step explanation:

m< I = m < 2 = m < 3

2 X - 30= o

X= 15

substitute in I

7X= 14

y = 2

Answer:

the correct answer is 16

Step-by-step explanation:

Add  ⇒ 16 to each side x2 – 8x = 9 to complete the square.

Answer:

207 or option a is the answer

Answer:

Option A) [tex]207[/tex]

Step-by-step explanation:

[tex]230\%[/tex] can be written as [tex]\frac{230}{100}[/tex] which is equivalent to the decimal form [tex]2.3[/tex]. The word of indicates that you will need to use the multiplication operation:

[tex]230\%[/tex] of [tex]90 = 2.3\times90[/tex]

[tex]= 207[/tex]

∴ [tex]230\%[/tex] of [tex]90[/tex] is [tex]207[/tex].

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
