Step-by-step explanation:

we start with the first and the third equations, as they have the same content structure.

we multiply the whole first equation by 2, so that the z terms become aligned, and then we add both equations :

-8x + 4z = 28

-2x - 4z = 22

--------------------

-10x + 0 = 50

x = -5

-2x - 4z = 22

-2×-5 - 4z = 22

10 - 4z = 22

-4z = 12

z = -3

y = x + z + 12

y = -5 - 3 + 12 = 4

Answer:

y=x+8

Step-by-step explanation:

The linear equation is given y=x+8

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here: Cost of entry=$8 and hourly rate of $1

Let the total cost is y and let the length of the rental in hours be x

then we construct an equation with linear relationship as follows:

y=x+8

Hence, The linear equation is given y=x+8

Half of 100 is 50

2/4 is half

Answer:

[tex]d = \frac{-1}{e} - \frac{7}{3}[/tex]

Step-by-step explanation:

In order to make d the subject of the formula, you need to isolate it.

- You started with d-7 = 4d + 3/e

- Move 4d to the left side by subtracting 4d from both sides to cancel it from the right so you have...

d - 7 = 4d + 3/e              This will leave you left with -3d - 7 = 3/e

-4d     -4d                          

- Then move over the -7 by adding 7 to both sides...

-3d - 7 = 3/e              This will leave you left with -3d = 3/e + 7

     +7          +7

- Finally to get d by itself divide both sides of the equation by -3 and you'll be left with...

[tex]d = \frac{3}{-3e} -\frac{7}{3}[/tex]

- You can cancel out the 3 in the -3/3e and make it -1/e so your final answer will be

[tex]d = \frac{-1}{e} - \frac{7}{3}[/tex]

Answer:

see the picture

Step-by-step explanation:

By the below figure (6) is the initial equation

(1) next added (b/2a)^2 on both sides to make it whole square on left side which gives (4) in (4) both terms are added on the right side to make it (5)

then square root on both sides gives (2) and now taking b/2a to the right side gives the final quadratic formula (3)

We can obtain the quadratic formula from completing the square method as shown.

The quadratic formula is derived from the completing the square method as follows;

Given the quadratic equation;

[tex]ax^{2} + bx + c =0[/tex]

Dividing through by a we have;

[tex]x^{2} + \frac{b}{a} + \frac{c}{a} = 0[/tex]

Adding half of b to both sides of the equation, we have;

[tex](x + \frac{b}{a}) ^{2} = \frac{-c}{a} + \frac{b^2}{4a^2}[/tex]

Taking LCM of the right hand side;

[tex](x + \frac{b}{2a})^{2} = \frac{b^2 - 4ac}{4a^2}[/tex]

Making x the subject of the formula;

[tex]x = \frac{-b + \sqrt{b^2 - 4ac} }{2a}[/tex]

Step-by-step explanation:

Number 1

m = (y2 - y1)/(x2 - x1)

m = (3 - 1)/(5 - 2)

m = 2/3 POSITIVE

Number 2

m = (y2 - y1)/(x2 - x1)

m = (-3 - 1)/(1 + 2)

m = -4/3 NEGATIVE

Number 3

m = (y2 - y1)/(x2 - x1)

m = (1 - 1)/(5 - 4)

m = 0/1

m = 0 ZERO

Number 4

m = (y2 - y1)/(x2 - x1)

m = (5 - 1)/(7 - 7)

m = 4/0

m = UNDEFINED

Number 5

m = (y2 - y1)/(x2 - x1)

m = (6 - 1)/(3 + 2)

m = 5/5

m = 1 POSITIVE

Answer:

One triangle could have one angle at 30 degrees and the other two angles at 75 degrees, while the other triangle could have two angles that are 30 degrees and one angle that is 120 degrees, therefore making them not similar.

Step-by-step explanation:

find the best fitting common multiple between 12 and 8.

let's start with the basic

8×12 = 96

96 fits 3 times into 300 with a remainder of 12.

so, 96 × 3 = 288

that means 288/12 = 24 packages of hot dogs and 288/8 = 36 packages of buns to create exactly 288 hot dogs.

any packages more or less would make the number of available buns and hot dogs "uneven".

Answer:

⇛-13/8 , -11/24, -7/16, -5/12 , -3/8

Step-by-step explanation:

Given numbers are -3/8 , 5/-12, -7/16, -13/18 , 11/-24

The can be written as -3/8, -5/12, -7/16, -13/18, -11/24

The denominators = 8,12,16,18,24

LCM of the denominators = 144

-3/8 = (-3/8)×(18/18) = -54/144

-5/12 = (-5/12)×(12/12) =-60/144

-7/16 = (-7/16)×(9/9) = -63/144

-13/18 = (-13/18)×(8/8) = -104/144

-11/24 = (-11/24)×(6/6) = -66/144

Ascending order of the numbers

= -104/144 , -66/144, -63/144, -60/144, -54/144

-13/8 , -11/24, -7/16, -5/12 , -3/8
