Answer:
The correct answer is option 2: -1
Step-by-step explanation:
In order to check if a number is zero of a function or not, the numer is put into the function in plave of variable. If the answer is zero thent he number is zero of the function and if the answer is not zero the given number is not a zero of the function.
Given function is:
[tex]x^3+x^2+x+1[/tex]
Putting x=1
[tex]=(1)^3+(1)^2+1+1\\=1+1+1+1\\=4[/tex]
1 is not zero of the function.
Putting x = -1
[tex]=(-1)^3+(-1)^2+(-1)+1\\=-1+1-1+1\\=0[/tex]
-1 is zero of the given function.
Hence,
The correct answer is option 2: -1

Find the value of c that completes the square
x^2-16x+c
Please help me with how to do this, and show me. Thank you.
Answer:
The value that completes the square is: c=8
Step-by-step explanation:
Find the value of c that completes the square [tex]x^2-16x+c[/tex]
The formula used is: [tex]a^2-2ab+b^2=(a-b)^2[/tex]
In the question given the value c can be found by breaking the middle term. we are given -16x while the general formula is 2ab for middle term so,
2(x)(8) = 16x
so, c= 8
Solving:
[tex]x^2-16x+c\\=x^2-2(x)(8)+(8)^2-(8)^2\\=(x-8)^2-64[/tex]
So, the value that completes the square is: c=8

Answer:
14x + 1
Step-by-step explanation:
4(2x-1)+3(2x+5) = 2x*4 - 1*4 + 2x*3 + 5*3
= 8x - 4 + 6x + 5
= 8x + 6x -4 + 5 {Combine like terms}

A company announces that it will be giving $4,200 of its profits to charity. If the company profits 28,000 what percent will the company give to charity
Given:
Company profits = $28,000
Charity = $4200
To find:
The percent that will the company give to charity.
Solution:
We have,
Company profits = $28,000
Charity = $4200
Now,
[tex]Charity\%=\dfrac{Charity}{Profit}\times 100[/tex]
[tex]Charity\%=\dfrac{4200}{28000}\times 100[/tex]
[tex]Charity\%=\dfrac{420}{28}\times 1[/tex]
[tex]Charity\%=15\%[/tex]
Therefore, the company will give 15% of its profit to charity.

Austin is planning a canoe trip with his dad and brother. They are taking a cooler and a few supplies that weigh a total of 89 pounds with them. The canoe has a maximum weight limit of 765 pounds. Which inequality can be used to find , the average allowable weight in pounds for each person in the canoe?
A. 3p - 89 > 765
B. 3p - 89 765
C. 3p + 89 > 765
D. 3p + 89 < 765
Answer:
3p + 89 < 765
Correct answer: D.
Step-by-step explanation:
Austin, his dad, and brother make a group of three people of varying weights. Assume their average weight is p and their total weight 3p.
The cooler and other supplies weigh 89 pounds in total.
The weight of the supplies and the three people in the canoe should not be equal or exceed the maximum allowable weight of the canoe of 765 pounds.
This leads to inequality:
3p + 89 < 765
Correct answer: D.

Answer:
the answer to your question is y = -30
Answer:
-30
-Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/2y+5=-10
Step 2: Subtract 5 from both sides.
1/2y+5-5=-10-5
1/2y+-15
Step 3: Multiply both sides by 2.
2*(1/2y)=(2)*(-15)
y=-30

What is the slope of the line that contains the points (-2, 2) and (3, 4)?
A.
O B. -
O c.
OD.
Answer: m = 2/5
Step-by-step explanation:
The formula for the slope is m = rise over run = y^2 - y^1 / x^2 - x^2
which makes it 4-2 over 3-(-2) which equals 2/5
Youre answer is 2/5
Answer:
The slope of the line that contains the points (-2, 2) and (3, 4) is 2/5.
Step-by-step explanation:
The slope of a line is denoted by m and is calculated using the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Here
[tex](x_1,y_1)[/tex] are the coordinates of the first point on line and
[tex](x_2,y_2)[/tex] are the coordinates of the second point on line
Given two points are:
(x1,y1) = (-2, 2)
(x2,y2) =(3, 4)
Putting the values in the formula
[tex]m = \frac{4-2}{3-(-2)}\\m = \frac{2}{3+2}\\m=\frac{2}{5}[/tex]
Hence,
The slope of the line that contains the points (-2, 2) and (3, 4) is 2/5.

-6a +3 =-3(2a-1) question number 2
Answer:
D. identity
Step-by-step explanation:
- 6a + 3 = - 3(2a - 1)
First, distribute -3 within the parenthesis.
- 6a + 3 = - 6a + 3
Subtract 3 from both sides of the equation
- 6a = - 6a
Divide - 6 on both sides of the equation
a = a
We know because both sides have the same equation, and that it is true, that this equation has infinite solutions, so the answer would be D. Identity
For those who don't know, identity in algebra means that the equation is true no matter what is substituted in for the variable. It will always be true.
I hope that this helps! :)
