Answer:

[tex]y = -x[/tex]

Step-by-step explanation:

Given

[tex]x: 1\ \ ||\ 2\ \ \ ||\ \ \ 3\ ||\ \ 4\ ||\ \ \ 5\ ||\ \ \ 6\ ||\ \ 7\ ||\ \ \ 8\ ||\ 9\ \ \ ||\ \ 10\ ||\ \ \ 11\ ||\ 12\\ y: -1 || -2|| -3 || -4 || -5 || -6|| -7 || -8 || -9 || -10 || -11 || -12[/tex]

Required

Write the equation of the  line;

Start by picking any two corresponding x and y values

[tex](x_1,y_1) = (1,-1)[/tex]

[tex](x_2,y_2) = (12,-12)[/tex]

Next, determine the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{-12 - (-1)}{12 - 1}[/tex]

[tex]m = \frac{-12 +1}{11}[/tex]

[tex]m = \frac{-11}{11}[/tex]

[tex]m = -1[/tex]

The equation is then calculated using:

[tex]y - y_1 = m(x - x_1)[/tex]

[tex]y - (-1) = -1(x - 1)[/tex]

[tex]y + 1 = -x +1[/tex]

[tex]y = -x[/tex]

Hence, the line equation is:

[tex]y = -x[/tex]

Answer: y=1/2x+8                                                                                                             When line goes up, rise and slope are positive.}

When line goes up, rise and slope are positive.

Answer:

x = 2

y = 149

Step-by-step explanation:

these two angles are equal to one another

(8x+15) = (7x+17)

solve for x

x = 2

two angles are supplementary

8x + 15 + y = 180

we know 8x+15 since x =2

8(2) + 15 + y = 180

16 + 15 + y = 180

31 + y = 180

solve for y

y = 180 - 31 = 149

Answer:

8 batches of cookies

Step-by-step explanation:

From the above question, we know that:

2/3 cups of sugar = 1 batch of cookies

Hence:

2/3 cups of sugar = 1 batch of cookies

5 1/3 cups of sugar = x batches

Cross Multiply

2/3 × x = 5 1/3 × 1

x = 5 1/3 / 2/3

x = 5 1/3 ÷ 2/3

x = 16/3 ÷ 2/3

x = 16/3 × 3/2

x = 8 batches of cookies

Therefore, Elena mades 8 batches of cookies with 5 1/3 cups of sugar

The future value be $ 12050

Investment definition is an asset acquired or invested in to build wealth and save money from the hard earned income or appreciation. Investment meaning is primarily to obtain an additional source of income or gain profit from the investment over a specific period of time.

Given:

P= $10 000

R=  3.75%

T= 5 years

n=4

Now,

Future Value= P[tex](1+r/n)^{nT}[/tex]

=1000[tex](1+0.0375/4)^{4.5}[/tex]

= 1000[tex](1+0.0375/4)^{20}[/tex]

=1000* 1.20517

= 12051.8

= $ 12050

Hence, the future value is $ 12050.

Consider the below figure attached with this question.

Given:

[tex]-4x+6>18[/tex]

To find:

The number of line that represents the solution of given inequality.

Solution:

We have,

[tex]-4x+6>18[/tex]

Subtracting 6 from both sides, we get

[tex]-4x>18-6[/tex]

[tex]-4x>12[/tex]

If an inequality is multiplied or divide by a negative number, then the sign of inequality must be change.

Divide both sides by -4.

[tex]x<\dfrac{12}{-4}[/tex]

[tex]x<-3[/tex]

The value of x is less than -3. It means number of the left of -3 are included in the solution set but -3 is not included in the solution set.

So, there is an open circle at x=-3 on the number and an arrow from -3  towards left.

Therefore, the correct option is A.

I don't see that choice in this picture so I hope that those are not all the choices

Step-by-step explanation:

Lets find all the angles first, that highlighted red square means that angle is a right angle, also known as 90 degrees, and the missing angle will be represented with b, also a triangle equals 180 degrees:

48 + 90 + b = 180

138 + b = 180

b = 42

So the missing angle is 42. If u didn't know, how wide an angle is effects the length of the side that it's facing. So because one of the angle is 48 degrees, the length of the side facing it is 10. So we needed to find the missing angle first to determine x, which we already did. So lets find the scale factor, we're dividing 42 with 48:

42/48 = 7/8

Now multiply 7/8 with 10:

10(7/8) = 70/8 = 8.75 = 8.8

Answer:

Step-by-step explanation:

A fraction has a numerator (above the fraction bar) and denominator (below the fraction bar). The denominator tells you the number of equal pieces one whole is divided into. The numerator tells you how many of those pieces you have.

If you have fewer than the total number of pieces, you have less than the whole amount.

If the numerator and denominator are equal, you have exactly the whole amount.

If the numerator is larger than the denominator, you have more than the whole amount.

__

The first fraction, 72/72 is equal to 1. Multiplying by that value gives the original number. The product is equal to 409.

__

The second and third fractions have numerators less than their denominator. They represent less than the whole amount, so multiplying by those values will give a product less than the original number:

  less than 751

  less than 173

Answer:

6 19/24

Step-by-step explanation:

To get our answer, we need to add 4 1/8 and 2 2/3. To do this, we need to find the LCM of 8 and 3, when we do some math, we know this is 24. Now, we need to convert 4 1/8 and 2 2/3 to improper fraction form. When we do this, we get 33/8 and 8/3. Now, we mulitply 33/8 by 3/3. When we do this, we get 99/24. Now, let's multiply 8/3 by 8/8. When we do this, we get 64/24. Now, let's add 64/24 and 99/24 (make sure not to add the bottom numbers). When we do this, we get 163/24. Let's simplify. Divide 163 by 24. When we do this, we get 6 with a remainder of 19. In mixed number form, 6 will be our whole number, 24 will be the denominator, and 19 will be the numerator. Let's write this out. When we do that, we get 6 19/24. Since 19 is a prime number, we can't simplify it any more than that, so 6 19/24 is our answer. I hope this helps!

Perhaps you want to know how many hours it takes to build each item.

If we let f, b, c represent the number of hours for a frame, bookcase, and chair, respectively, the equations can be written as ...

Your graphing calculator or an on-line matrix solver can find the reduced row-echelon form of the augmented matrix ...

  [tex]\left[\begin{array}{ccc|c}4&1&3&78\\6&0&4&108\\3&5&2&74\end{array}\right][/tex]

That result will tell you ...

  (f, b, c) = (14, 4, 6)

It takes 14 hours to build a bed frame, 4 hours to build a bookcase, and 6 hours to build a chair.

the solution to the equation is m = 5.

To solve the equation 2(2m) + 4(4m + 2) = 108 for m, we simplify and apply the order of operations.

First, we distribute the multiplication:

4m + 16m + 8 = 108

Combine like terms:

20m + 8 = 108

Next, we isolate the term with the variable. Subtract 8 from both sides:

20m = 100

To solve for m, we divide both sides of the equation by 20:

m = 5

Therefore, the solution to the equation is m = 5.
