Answer:

4x+10+14x+3=157

18x+13=157

18x=157-13

18x = 144

X = 144 /18

X= 8

NFE= 14x+3

= 14(8)+3

=112+3

=115

Step-by-step explanation:

x+7y+2z=−12

I'm not 100% sure though

Answer:

Another 2 1/5

Step-by-step explanation:

2.5 + 2.5 = 5.0 (You don't have to put the .0)

Another example would be:

5.5 + 5.5 = 11.0 (Again, you do not have to put the .0)

Answer:

The slope of line b would be -1/7.

Step-by-step explanation:

This happens because if you have the slope of any line and are trying to find the perpendicular line to said line, the slope of the perpendicular line will always be the opposite reciprocal of the original slope.

Then, all you need to do is find some points and graph the lines.

Answer:10

Step-by-step explanation:

Answer:

non linear

Step-by-step explanation:

when you graph it, the line is a zero slope

Answer:

y = -4x - 10

Step-by-step explanation:

y-6=-4(x+4)

1: distributive property

y-6= -4x - 16

2: add 6 both sides

y = -4x - 10

Answer:

-1+3=2

Step-by-step explanation:

answer:-1

Answer:

w=-13/4

w=2

Step-by-step explanation:

|8w+5|=21

Step by step solution :

STEP

1

:

Rearrange this Absolute Value Equation

Absolute value equalitiy entered

     |8w+5| = 21

STEP

2

:

Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |8w+5|

For the Negative case we'll use -(8w+5)

For the Positive case we'll use (8w+5)

STEP

3

:

Solve the Negative Case

     -(8w+5) = 21

    Multiply

     -8w-5 = 21

    Rearrange and Add up

     -8w = 26

    Divide both sides by 8

     -w = (13/4)

    Multiply both sides by (-1)

     w = -(13/4)

    Which is the solution for the Negative Case

STEP

4

:

Solve the Positive Case

     (8w+5) = 21

    Rearrange and Add up

     8w = 16

    Divide both sides by 8

     w = 2

    Which is the solution for the Positive Case

STEP

5

:

Wrap up the solution

w=-13/4

w=2

Answer:

35

Step-by-step explanation:

brackets symbolise multiplication,which means you have to multiply the numbers in both brackets by each other including their signs.

a negative multiplied by a negative is a positive and 7×5 is 35

therefore

-7×-5=35

Answer:

Question 1: [tex]x=4[/tex]

Question 2: [tex]x= \pm7[/tex]

Question 5: The dimensions of one face of the container are 6 by 6 inches.

Step-by-step explanation:

Hi there!

Question 1

[tex]x^3=64[/tex]

Rewrite 64 as a power of 3:

[tex]x^3=4^3[/tex]

(We could find that 4³ = 64 through trial and error)

This above equation makes it true that x=4. If aⁿ = bⁿ, then a=b:

[tex]x=4[/tex]

Question 2

[tex]x^2=49[/tex]

Rewrite 49 as a power of 2:

[tex]x^2=7^2[/tex]

Again, we could have found this through trial and error, or by looking at our multiplication tables.

[tex]x=7[/tex]

However, remember that positive and negative numbers will all square to be a positive number. So, therefore, x can be -7 OR 7 (since both, when squared, equal 49):

[tex]x= \pm7[/tex]

Question 5

Let x be equal to the length of one edge of the cube.

Volume of a cube formula: [tex]V=x^3[/tex]

Plug in the given information, when V is the volume:

[tex]216=x^3[/tex]

Rewrite 216 as a power of 3:

[tex]6^3=x^3[/tex]

^ We could have found this through trial and error.

[tex]x=6[/tex]

Therefore, the dimensions of one face of the container are 6 by 6 inches.

I hope this helps!

Answer:

The slope is 5/3

Step-by-step explanation:

-3 over to 0 is 3, so you get the run.

-2 up to 3 is 5, so you get the rise.

Slope is rise over run, which gives the answer of 5/3.

Good luck!

1. v= 0.013m/s

t = 60 seconds

d = v×t

= 0.013×60

= *0.78 m*

2. v= 17.6 m/s

d= 100m

t = d/t

= 100/17.6

= *5.68 s*

Answer:

Step-by-step explanation:

Let x, y, z represent the numbers of cheeseburgers, plain burgers, and chicken burgers ordered for the party.

We have three relations given. Each can be used to write an equation.

  x + y + z = 500 . . . . . . . . . a total of 500 meals were ordered

  2.50x +1.75y +3.20z = 1172.50 . . . . . the total cost

  0x +y -z = 100  . . . . . . . . . . 100 fewer chicken were ordered than plain

_____

Additional comment

We put the coefficient of x as 0 in the last equation to facilitate writing this system as an augmented matrix.

  [tex]\left[\begin{array}{ccc|c}1&1&1&500\\2.50&1.75&3.20&1172.50\\0&1&-1&100\end{array}\right][/tex]

The solution is (x, y, z) = (300, 150, 50).
