Answer:

x + 4x = 5x

Step-by-step explanation:

An identity is a mathematical equation that is always true (here - for all possible x's).

a). x + 4x = 5x; this is true, because for any possible x

x+4x = (1 + 4)x = 5x; there's not much to add.

b). 6x=18; evaluates to

x = 3; so it only works for one x, not all possible xs.

c). 2x + 1 = 7

2x = 6

x = 3; so it only forks for one x

d). 7x + 9 = x

6x + 9 = 0; we could compute the exact x it works for from here, but suffice to say this doesn't work for x = 0.

In between these given equations, x + 4x = 5x is the correct identity here.

"An identity is an equality relating one mathematical expression A to another mathematical expression B, such that A and B produce the same value for all values of the variables within a certain range of validity."

Given equations are:

1. x + 4x = 5x

⇒ 5x = 5x

This equation is true for all values of 'x'.

Hence, this is a correct identity.

2. 6x = 18

⇒ x = 3

This equation is true when x = 3.

3. 2x + 1 = 7

⇒ 2x = 6

⇒ x = 3

This equation is true when x = 3.

4. 7x + 9 = x

⇒ 6x = - 9

⇒ x = - 9/6

⇒ x = - 3/2

This equation is true when x = - 3/2.

Answer:

4(7w+10)

Step-by-step explanation:

Answer:

4(7w+10)

Step-by-step explanation:

Answer:

a(n) = 12 + 8n

a1 = 20

a2 = 28 = 20 + 8

a3 = 36 = 20 + 8.2

a4 = 44 = 20 + 8.3

.......

=> this is a arithmetic with a1 = 20

d = 8

=> an = 20 + 8(n - 1) = 12 + 8n

Answer:

$45

Step-by-step explanation:

Given that :

Amount collected = $55

Amount left after purchasing sporting gear = $10

The cost of sorting gear:

Amount collected - amount left after purchase

$55 - $10 = $45

Answer: ≈ 551.71 ft²

All work is shown in the picture.

Answer:

551,7

see in the picture, this composite figure is made up of a rectangle and 2 halves of a circle

=> the area of this composite figure = the area of a rectangle + the area of a circle

+) the area of the rectangle = 15.25 = 375

+) the area of the circle = (15/2)².pi = 56,25pi

=> the area of this figure = 375 + 56,25pi = 551,7

Answer:

[tex]y-(9)=(-8)(x-8)\\[/tex]

Step-by-step explanation:

[tex](x_1, y_1) = (8, 9)\\(x_2, y_2) = (9,1)\\[/tex]

Step one: Find the slope (m)

[tex]slope=m=\frac{rise}{run} =\frac{y_2-y_1}{x_2-x_1} = \frac{1-9}{9-8} =\frac{-8}{1} =-8[/tex]

Step two: Plug your known values into the point-slope equation

[tex]m=-8\\y_1=9\\x_1=8\\[/tex]

Point-slope form is [tex]y-y_1=m(x-x_1)[/tex]

[tex]y-(9)=(-8)(x-8)\\[/tex]

If you want to convert point-slope form to general form, isolate for y.

[tex]y-9=-8x+64\\y=-8x+73[/tex]

Explicație pas cu pas:

Care este cel mai mic număr între 95.999; 96.959; 99.595 și 99.995, unde numărul de mii este 5

95.999 = Nouăzeci și cinci de mii nouă sute nouăzeci și nouă

96.959 = Nouăzeci și șase de mii nouă sute cincizeci și nouă

99595 = Nouăzeci și nouă de mii cinci sute nouăzeci și cinci

99995 = Nouăzeci și nouă de mii, Nouă sute nouăzeci și cinci.

Answer:

55 = 5x

Step-by-step explanation:

Sadie had 55 stickers. Each day she gave away 5 stickers to her friends.

Write an equation to model this situation in the form y = mx + b, but do not

include any spaces in your answers. (for example y=6x+1)

Equation to model this situation in the form y = mx + b,

y = Total number of stickers she had

x = Number of days that she gave away sticker

b = Fixed value = 0

Hence:

55 = 5x + b

b = Fixed value = 0

Therefore, the situation is represented as:

55 = 5x

3(2x+8)=0

Step 1: Simplify both sides of the equation.

3(2x+8)=0

(3)(2x)+(3)(8)=0(Distribute)

6x+24=0

Step 2: Subtract 24 from both sides.

6x+24−24=0−24

6x=−24

Step 3: Divide both sides by 6.

Answer:

Step-by-step explanation:

For option A: Earning = 0.06 x $73,620 = $4,417.20

For option B: Earning = $3,000 + 0.02 x $73,620 = $3,000 + $1,472.40 = $4,472.40

For option C: Earning = 0.04 x $50,000 + 0.09 x ($73,620 - $50,000) = $2,000 + 0.09 x $23,620 = $2,000 + $2,125.80 = $4,125.80

For option D: Earning = 0.05 x $35,000 + 0.07 x $(73,620 - 35,000) = $1,750 + 0.07 x $38,620 = $1,750 + $2,703.4 = $4,453.40
