10 POINTS!!!!
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)

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
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].

What is a function?"It defines a relation between input and output values.""In function, for each input there is exactly one output."What is cube root?"The function of the form [tex]f(x)=\sqrt[3]{x}[/tex] "
What is reciprocal function?"This function obtained by finding the inverse of a given function."
What is square root function?"The function of the form [tex]f(x)=\sqrt{x}[/tex] "
What is an absolute value function?"The function of the form f(x) = |x| "
For given question,
We have been given the graph of a function.
We need to identify the parent function for the given the graph.
We can observe that the graph increases slowly.
The range of the function is set of all positive values.
We know that the range of square root function is always positive.
If we draw the graph for following functions
i) cube root function
ii) reciprocal function
iii) square root function
iv) absolute value function
Then the parent function of given graph is a square root function

This is because 30d would be multiplying whatever the cost by 30, however with 0.3d you are taking 0.3 or 30% off of the whole number.
Write the word sentence as an inequality.
A number z times 3 is at most -4.8
Answer and you’ll get brainliest answer if correct!
Answer:
3z < -4.8
* be sure to use the less than or equal to sign
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

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

solve the following system of equations y=9x-9 y=9
Answer:
(x, y) = (2, 9)
Step-by-step explanation:
y = 9x - 9
y = 9
Substituting the value of y ( second equation) into the first eqaution, we get:
9 = 9x - 9
18 = 9x
x = 2.
Answer:
(x, y) = (2, 9)
Step-by-step explanation:
y = 9x - 9
y = 9
Substituting the value of y ( second equation) into the first eqaution, we get:
9 = 9x - 9
18 = 9x
x = 2.

Given:
Consider the expression is

Jeremy factored the given expression and his steps are given.
To find:
The error in his solution.
Solution:
We have,
[tex]144x^2-100[/tex]
It can be written as
[tex]=12^2x^2-10^2[/tex]
[tex]=(12x)^2-10^2[/tex]
[tex]=(12x+10)(12x-10)[/tex] [tex][\because a^2-b^2=(a+b)(a-b)][/tex]
Taking out common factors from each parenthesis.
[tex]=2(6x+5)2(6x-5)[/tex]
[tex]=4(6x+5)(6x-5)[/tex]
So, Jeremy was incorrect because the common factor is [tex]2\times 2=4[/tex] instead of 2.
Therefore, Jeremy made his mistake in his last step.

-3x-8>19?I have to solve for x
Answer:
x < -9
Step-by-step explanation:
Add 8 to both sides:
-3x - 8 > 19

Divide each side by -3:
-3x > 27
Dividing by a negative number on each side switches the inequality:
x < -9

Answer:
circle graph
Step-by-step explanation:
The function with range -4 ≤ y ≤ 3 and domain 0 ≤ x ≤ 3 represents a circle. The graph is shown below.
What is a graph?A graph is a diagram that depicts the relationship between two variables, usually measured along opposite axes in a pair, is used.
The range of the function is given below,
-4 ≤ y ≤ 3.
And the domain of the function is grater than or equal to 0 and less than or equal to 5.
Implies that,
0 ≤ x ≤ 3.
And the value of y varies from -4 to 3, for the values of x.
So the graph of the function can be a circle,
