Answer:

-x2*(9x-5)

Step-by-step explanation:

Answer:

x = -1

Step-by-step explanation:

-11 + 9(x+1) = 4(1+3x) - 3

9x + 9 - 11 = 12x + 4 -3

9x - 2 = 12x +1

-2 = 3x + 1

-3 = 3x

x = -1

Hope this helped

Answer:

5 cm/s

Step-by-step explanation:

The rate of change (ROC) is the speed at which the y variable (hieght) increases with the x variable (time). so ROC = 5.

the linear equation is y = mx + b, m is also the roc, b is the initial value, so,

if y = 60, x = 4 & b = 40, then making m the subject of equation will give the value of the ROC. i.e m = (y - b)/x = (60 - 40)/4.

Answer:

x = 1.25

Step-by-step explanation:

7(4 - 2x) - 6x = 3

(28 - 14x) - 6x = 3

-28                  - 28

- 14x - 6x = - 25

- 20x = - 25

/ -20    / -20

x = 1.25

Answer:

The answer is below

Step-by-step explanation:

From the image of the leaning tower of Pisa, we can see that it passes through the point (7.75, 0) and (10.75, 42).

a) The equation of a line in slope intercept form is given by y = mx + b, where m is the slope and b is the intercept. Also, the equation of line passing through

[tex](x_1,y_1)\ and\ (x_2,y_2)\ is:\\\\y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]

Hence since it passes through  (7.75, 0) and (10.75, 42), the equation is:

[tex]y-0=\frac{42-0}{10.75-7.75} (x-7.75)\\\\y=14(x-7.75)\\\\y=14x-108.5[/tex]

b) When the tower is 56 meters tall, i.e. y = 56, we need to find the value of x:

y = 14x - 108.5

56 = 14x - 108.5

56 + 108.5 = 14x

164.5=14x

x = 164.5/14

x = 11.75

When the tower is 56 meters tall, the top of the tower is 11.75 m off center

Answer:

Step-by-step explanation:

Answer:

A.

Step-by-step explanation:

y = mx + b

y = -2/3 x + b

(x, y) = (3, 0)

0 = -2/3 (3) + b

0 = -2 + b

b = 2

y = -2/3 x + 2

Answer: A.

Answer:

y = - 2/3 + 2

Step-by-step explanation:

Step 1:

y = mx + b     Slope Intercept Form

Step 2:

y = - 2/3x + b   Input Slope

Step 3:

0 = - 2/3 ( 3 ) + b       Input x and y

Step 4:

0 = - 2  + b     Multiply

Step 5:

2 = b       Add 2 on both sides

Answer:

y = - 2/3 + 2

Answer:

z = 14

Step-by-step explanation:

subtract 26 from both sides to isolate the variable, you should get: -z = -14

then divide both side by the negative sign, so you should get: z = 14

Answer:

z=14

Step-by-step explanation:

−z + 26 = 12

-z=12-26

-z=-14

z=14

These are just some equivalent fractions of 8/4:

= 82/41 = 84/42 = 86/43 = 88/44

= 90/45 = 92/46 = 94/47 = 96/48

= 194/97 = 196/98 = 198/99 = 200/100

So, yes.

Answer:

1. [tex]-5-\sqrt{x}[/tex]

2. [tex]7+\sqrt{b}[/tex]

Step-by-step explanation:

The conjugate of a radical expression

[tex]a+\sqrt{b}[/tex]

is the expression

[tex]a-\sqrt{b}[/tex]

And vice-versa.

The conjugate is mostly used to rationalize radical expressions because the expression by its conjugate produces another expression without the radicals.

The question asks to find the conjugate of:

1. [tex]-5+\sqrt{x}[/tex]

The conjugate is

[tex]-5-\sqrt{x}[/tex]

2. [tex]7-\sqrt{b}[/tex]

The conjugate is

[tex]7+\sqrt{b}[/tex]

Answer:

A. $ 58.50

B. $ 80

C. No, it did not mark up 30%

Step-by-step explanation:

Since,

A. We have,

Mark up percentage = 30%

Actual price = $ 45,

 B. We have,

SP = $ 104,

  C.  We have,

AP = $ 75,

SP = $100,

Thus, mark up percentage =  

= 33.33 %

Hence, store did not mark up the price by 30%.

Answer:

$ 72.80

Step-by-step explanation:

30% of 104 = 0.30 * 104

                  = $ 31.20

Money paid by the store = 104 - 31.20

                                         = $ 72.80

The value of  8/9/20 could be either 0.04 or 17.77.

In such a fraction, the value that appears above the horizontal line is referred to as the numerator.

In another word, the fraction is the division of the two numbers but the division is not wholly complete.

In another word, if we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

Given the fraction,8/9/20

Case 01)

(8/9)/20 = 0.888/20 = 0.044.

Case 02)

8/(9/20) = 8/0.45 = 17.77.

Hence "The value of  8/9/20 could be either 0.04 or 17.77".
