Answer:
2y + 2z
6x³+2x²-10 + 2x²-24
6x³+4x²-34 ■
Step-by-step explanation:
The polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.
What is Polynomial?A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer.
Here, y = 3x³+x²-5 and z = x²-12
Now,
2 ( y + z ) = 2 ( 3x³+x²-5 + x²-12 )
2 ( y + z ) = 2 ( 3x³ + 2x² - 17 )
2 ( y + z ) = 6x³ + 4x² - 34
Thus, the polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.

Identify the conclusion of the statement.
If 2n-7 > 25, then n > 16
1- 2n-7 > 25
2- n > 16
3- 2n > 32
4- no conclusion can be made
Answer:
2) n > 16
Step-by-step explanation:
Usually, a statement is written as:
If P, then Q
Where P = hypothesis
Q = conclusion.
And our statement is:
if 2n - 7 > 25, then n > 16
(We can easily solve the inequality to get the thing in the right:
2n - 7 > 25
2n > 25 + 7 = 32
n > 32/2 = 16
n > 16 )
then:
P = (2n - 7)
Q = n > 16
Then the conclusion is: n > 16
The correct option is 2) n > 16

Find a coordinates of the midpoint of the line segment with the given endpoints (7,4), (9,-1)
Answer:
Coordinates of midpoint are (8,1.5).
Step-by-step explanation:
Given coordinates of end points are;
(7,4) and (9,-1)
we can find the coordinates of mid-point,
[tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Here,
x1 = 7 and y1 = 4
x2 = 9 and y2 = -1
Putting these values in formula
Coordinates of mid point = [tex](\frac{7+9}{2},\frac{4+(-1)}{2})\\[/tex]
Midpoint = [tex](\frac{16}{2},\frac{4-1}{2})[/tex]
Midpoint = [tex](\frac{16}{2},\frac{3}{2})[/tex]
Midpoint = 8 , 1.5
Hence,
Coordinates of midpoint are (8,1.5).

(A.P.E.X)
The function g(x) is g(x) = 4x² after applying the tansformation because the f(x) is the parent function option (A) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
The options are:
A. g(x)=4x²
B. g(x)=16x²
C. g(x)=1/4x²
D. g(x)=(4x)²
It is given that:
f(x) = x²
From the graph as we can see the function f(x) is the parent function and g(x) is transformed function.
The function g(x):
g(x) = ax²
Plug x = 1
g(x) = 4
4 = 1²a
a = 4
g(x) = 4x²
Thus, the function g(x) is g(x) = 4x² after applying the tansformation because the f(x) is the parent function option (A) is correct.

(just trying to check my work because i did this question twice and one answer was 6 the other was 11.4)
Answer:
The answer is 11.401754
Answer: Approximately 11.4 units
================================================
Work Shown:
(x1,y1) is the first point (-6,-2)
(x2,y2) is the second point (5,1)
Apply the distance formula
[tex]d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\d = \sqrt{(-6-5)^2+(-2-1)^2}\\\\d = \sqrt{(-11)^2+(-3)^2}\\\\d = \sqrt{121+9}\\\\d = \sqrt{130}\\\\d \approx 11.4017542509913\\\\d \approx 11.4\\\\[/tex]

From this information, how many people out of 100 would you expect to order chicken?
Answer:
36 people would order chicken.
Step-by-step explanation:
Case I: (50 People in Total)
Total Number of People Ordering=8+10+18+14=50
Percentage of People ordering chicken=people ordering chicken/total number of people=18/50=0.36%
Case II: (100 People in Total)
Number of People ordering chicken=percentage of people ordering chicken x total number of people=0.36 x 100=36
During crawfish season, Xavier sells crawfish for $62.50 per sack and charges a $20.00 delivery fee. Which equation best represents y, the total cost of x sacks of crawfish delivered to a customer?
A y = (62.50 + 20)x
B y = 62.50 + 20x
C y + 20 = 62.50x
D y = 62.50x + 20
Answer:
d
Step-by-step explanation:
The equation that best represents y, the total cost of x sacks of crawfish
delivered to a customer is y = 62.50x + 20
y = total cost of x sacks of crayfish
x = number of sacks of crayfish
Therefore,
delivery fee = $20.00
The delivery fee is just like a constant in the equation.
amount sold per sack = $62.50
The amount sold per sack is like the slope in the equation.
Therefore,
y = 62.50x + 20

The probability of picking a chocolate chip cookie is 1/3.
Given that, a box contains 5 chocolate chip cookies, 4 sugar and 6 oatmeal raisin.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes
Here,
Total number of outcomes =15
Number of favorable outcomes = 5
Probability of an event = 5/15
