Answers

Answer:

(z - 2) (z^2 + 9)

Step-by-step explanation:

Factor the following:

z^3 - 2 z^2 + 9 z - 18

Hint: | Factor pairs of terms in z^3 - 2 z^2 + 9 z - 18 by grouping.

Factor terms by grouping. z^3 - 2 z^2 + 9 z - 18 = (z^3 - 2 z^2) + (9 z - 18) = z^2 (z - 2) + 9 (z - 2):

z^2 (z - 2) + 9 (z - 2)

Hint: | Factor common terms from z^2 (z - 2) + 9 (z - 2).

Factor z - 2 from z^2 (z - 2) + 9 (z - 2):

Answer: (z - 2) (z^2 + 9)

Answer:

The price of each big peach is: $0.45

Step-by-step explanation:

Given that

Total peaches = 270

The ratio of small to medium to big peaches

2:4:3

We can use this ratio to find the number of peaches in each group

First of all we have to find the sum of ratios

That is

2+4+3 = 9

Now

[tex]Small\ peaches = \frac{2}{9} * 270 = 60\\Medium\ peaches = \frac{4}{9}*270 = 120\\Big\ peaches = \frac{3}{9} *270 = 90[/tex]

It is also given that total cost is $91.50

We will have to find the cost of small and medium peaches and then subtract both from the total cost to find the price of big peaches.

So,

Price of one small peach = $0.25

Total cost = 0.25*60 = 15

Price of one medium peach = $0.30

Total cost = 0.30*120 = 36

[tex]Price\ of\ all\ medium\ peaches = Total\ cost-(Cost\ of\ small\ peaches+ Cost\ of\ medium\ peaches)\\= 91.50 - (15+36) \\=91.50-51\\=40.5[/tex]

To find the cost of one big peach, the cost of big peaches will be divided by total number of peaches

So,

[tex]Cost\ of\ one\ peach = \frac{40.5}{90} = 0.45[/tex]

Hence,

The price of each big peach is: $0.45

0.45 cent

Given that

Total peaches = 270

The ratio of small to medium to big peaches.

2:4:3

We can use this ratio to find the number of peaches in each group

First of all we have to find the sum of ratios

That is

2+4+3 = 9

It is also given that total cost is $91.50

We will have to find the cost of small and medium peaches and then subtract both from the total cost to find the price of big peaches.

So,

Price of one small peach = $0.25

Total cost = 0.25*60 = 15

Price of one medium peach = $0.30

Total cost = 0.30*120 = 36

To find the cost of one big peach, the cost of big peaches will be divided by total number of peaches.

So the price of each big peach is: $0.45

Step-by-step explanation:

The inequality for the A number z times 3 is at most -4.8 is 3x < -4.8

What is Inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

A number z times 3 is at most -4.8

Now, the mathematical expression is

3z < -4.8

and, z< -1.6

Hence, the inequality is 3x < -4.8

Step-by-step explanation:

The expression {8/10 + 2/6} is equivalent to 17/15.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is the expression as -

8/10 + 2/6

The given expression is -

8/10 + 2/6

(2 x 4)/(2 x 5) + (2 x 1)/(2 x 3)

4/5 + 1/3

(12 + 5)/15

17/15

Move the number that is not next to the variable to the other side of the equation by using the opposite operation Divide by the number next to the variable 8x -1 = -50

Answers

Given:

The equation is

[tex]8x-1=-50[/tex]

To find:

The value of x by separating the variable.

Solution:

We have,

[tex]8x-1=-50[/tex]

Here, -1 is not next to the variable. So, move -1 to the other side of the equation by using the opposite operation. After moving -1 to the right side of the equation it will become +1.

[tex]8x=-50+1[/tex]

[tex]8x=-49[/tex]

Divide both sides by 8.

[tex]x=\dfrac{-49}{8}[/tex]

Therefore, the value of x is [tex]\dfrac{-49}{8}[/tex].
