(Will l give 25 points!) Solve the system of linear equations by substitution. -8x + y = 5 and 5x - y = 3

Answers

Answer:

x = -8/3 and y = -49/3

Step-by-step explanation:

(Step 1) To solve using substitution, you first need to isolate a variable in one of these equations. I chose to isolate "y" in the following equation.

-8x + y = 5                                        <--- Original equation

y = 5 + 8x                                         <--- Add 8x to both sides

(Step 2) Now, substitute (5 + 8x) for "y" in the second equation.

5x - y = 3                                          <--- Original equation

5x - (5 + 8x) = 3                               <--- Substitute 5 + 8x for "y"

5x - 5 - 8x = 3                                  <--- Distribute (-) in the parentheses

-3x - 5 = 3                                        <--- Combine terms with "x"

-3x = 8                                              <--- Add 5 to both sides

x = -8/3                                             <--- Divide both sides by -3

(Step 3) Since you know the value of "x", plug it into one of the equations to solve for "y".

y = 5 + 8x                                         <--- Original (rearranged) equation

y = 5 + 8(-8/3)                                   <--- Plug (-8/3) for "x"

y = 5 - 64/3                                       <--- Multiply

y = 15/3 - 64/3                                   <--- Convert 5 into a fraction

y = -49/3                                           <--- Subtract

(Step 3.5) You can check your work by plugging "y" into the other equation to see if the answer for "x" is the same.

5x - y = 3                                             <--- Original equation

5(-8/3) - y = 3                                      <--- Plug (-8/3) for "x"

-40/3 - y = 3                                        <--- Multiply

-40/3 - y = 9/3                                     <--- Convert 3 into a fraction

-49/3 - y = 0                                        <--- Subtract both sides by 9/3

-49/3 = y                                             <--- Add both sides by "y"

The value of the system of equations is x = -8/3 and y = -49/3.

Answers

Answer:

A.) 15984.42cm^2/5088πcm^3

B.) 3466.56cm^2/1104πcm^2

Step-by-step explanation:

A.) fine the V of the cone and then cylinder then add them.

B.) The cone you have to find the LA (lateral area) to do that you would do is find S (slant) so you would do 12^2+16^2 which is 400 then u have to find the square root of it which is 20 which is that slant of the cone. After that you would do 12x20 which gives 240 that would be the LA of the cone.

Then you would find the LA of the cylinder which you have to do is 30x12 which is 360 then multiply it by 2 which gives 720.

Lastly you find the area of the base which in this case is a circle and that would be 144 add all of them then get the SA

a is true because the graph is measuring the weight of the box based on the number of cookies in it, and the box has weight even without cookies in it.

b is false because the slope of the line is 1/2, and each cookie weighs 1/4 oz.

c is false because there is an association between the number of cookies and the weight of the box.

d is false because that is the weight of one cookie, and doesn't take into account the weight of the box by itself.

e is true because the graph shows that at 13 cookies, the box weighs around 3.75 ounces.

To find the volume of a rectangular prism you multiply the 3 dimensions, length x width x height. What combination of numbers will give me a volume of 17?

Answers

1, 1 and 17. Since 17 is a prime number, there isn’t exactly numbers that are multiplied by each other that give 17.

Answer:

1, 1, 17

Step-by-step explanation:

17 is a prime number. This means the only factors are 1, and 17. This means that since only 17, and 1 multiply to 17, to get a volume of 17 you can only use 1, and 17 (1, 1, and 17)

Step-by-step explanation:

Let x, and x+1 be the consecutive numbers.

[tex]x + (x + 1) = 37[/tex]

[tex]2x + 1 = 37[/tex]

[tex]2x = 36[/tex]

[tex]x = 18[/tex]

Plug in 18 for x+1,

[tex]18 + 1 = 19[/tex]

So the numbers is 18,19

Answer:

18 and 19

Step-by-step explanation:

if you have two consecutive numbers, then using algebra, one unknown number is x and the other unknown consecutive number is x + 1

The equation x + x + 1 = 37

To solve this equation subtract 1 from both sides as one does in algebra.

x + x + 1 = 37 → x + x + 1 - 1 = 37 - 1

Now you have the equation x + x = 36

This can rewrite this as 2x = 36        2x means 2 times the value of x

To solve this part of the equation divide both sides by 2

2x / 2 = 36 / 2

x = 18

The next consecutive number x + 1 = 19, (18) + 1 = 19

check this by adding. 18 + 19 = 37.
