-6,6
4, 1,3
0 -3,-1,4
o 1,3
Answer: option B
Step-by-step explanation:
-4, 1, 3
The roots of the polynomial equation x³ - 7x = 6x - 12 is given by the values x = -4 , 1 , 3
What is a polynomial?Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the polynomial equation be represented as A
Now , the value of A is
x³ - 7x = 6x - 12 be equation (1)
Now , it can be represented as 2 equations of the form
A = x³ - 7x be equation (2)
And , B = 6x - 12 be equation (3)
On plotting the graphs of the two equations , we get
The point of intersection of the equations is at P ( -4 , -36 ) , Q ( 1 , -6 ) and R ( 3 , 6 )
Therefore , the x coordinates of the points are x = -4 , 1 , 3
Hence , the roots of the polynomial is x = -4 , 1 , 3

Gabe bought five sacks of apples each sack weighed 12 lb he paid three for each pound of apples what was the total cost of all of the apples Gabe bought
Answer:
The cost of 12lbs of apples is $36.
Step-by-step explanation:
⟹ Lets Solve!
⟹ First we must define x and y.
x is the lb's of apples and y is the cost.
⟹ Now lets form our equation.
[tex]3x = y[/tex]
[tex]x = 12[/tex]
⟹ Since gabe bought 12 pounds of apples x = 12.
⟹ Now substitute x for 12.
[tex]3x = y[/tex]
[tex]3(12)= y[/tex]
⟹ Now multiply.
[tex]36 = y[/tex]
The cost of 12lbs of apples is $36.
Describe how to use scientific notation to write a very large number. Give an example written in both standard form and scientific notation.
Answer:
Scientific notation is simply changing a number to x times 10^n, where x is no more than 10 and more than 1.
For example, 134 would be 1.34 times 10^2.
choose the graph that represents the linear equation y = 2x + 1
Answer:
The third option is the answer.
Step-by-step explanation:
In the formula y = mx + b, using the equation given,
m = 2, which means that the line goes up 2 units and right 1 unit.b = 1, which means that the y-intercept, or where the line touches the y-axis, is 1.Answer:
the 3rd option
Step-by-step explanation:
In the formula y = tx + b, using the equation given,
t = 2, which means that the line goes up 2 units and right 1 unit.
b = 1, which means that the y-intercept, or where the line touches the y-axis, is 1.

Answer:
y=mx+b
Step-by-step explanation:
Answer:
y = (5/2)x - 5
Step-by-step explanation:
SLOPE:
The slope is rise over run, and in this case (thanks to the graph), we can do the [difference of y] / [difference of x] pretty easily. This is 5 / 2
Y-INTERCEPT:
Y-intercept is simple: where the line touches the y-axis. This happens at y = -5.

[tex]\bold{204.4~and~217.6.}[/tex]Solution Steps:
First you need to solve the real inequality to understand how to find the rest of the possible equations.
Subtract 13.2 from both sides:
[tex]13.2-13.2=[/tex] Cancels Out[tex]217.6-13.2=204.4[/tex]So now we know the real answer, but now we must find all the possible solutions.
(Means anything greater than or equal to 217.6 when you plug it into x + 13.2 ≥ 217.6.)
Numbers that are greater than 378:
1.) [tex]204.4+13.2=217.6[/tex] ≥ [tex]217.6[/tex] (True)
2.) [tex]217.6+13.2=230.8[/tex] ≥ [tex]217.6[/tex] (True)
3.) [tex]204.3+13.2=217.5[/tex] ≥ [tex]217.6[/tex] (False)
4.) [tex]0+13.2=13.2[/tex] ≥ [tex]217.6[/tex] (False)
5.) [tex]13.2+13.2=26.4[/tex] ≥ [tex]217.6[/tex] (False)
6.) [tex]200.4+13.2=213.6[/tex] ≥ [tex]217.6[/tex] (False)
7.) [tex]-200+13.2=-186.8[/tex] ≥ [tex]217.6[/tex] (False)

——PLEASEE HELP.!! ILL GIVE BRAINLIEST.!! *EXTRA POINTS* DONT SKIP:((———
Answer:
The slope is 0 because it is a straight line
Step-by-step explanation:
Answer:
undefined.
Step-by-step explanation:
You could be really formal and use the slope formula
The y values are both the same -- 4.
The x values are 3.5 and 6.5
Therefore the slope is (6.5 - 3.5) / (4 - 4)
The denominator is 0
The slope is undefined because 3/0 is not very well behaved.
A horizontal line always gives an undefined amount.

AVA HEART RATE IS 65 beats per minute. If Avas heart beat 604,800 times, how many full days would have elapsed
Answer:
520 full days.
Step-by-step explanation:
Since I'm not that smart I looked up how many minutes are in a day and got a total of 1440 minutes in a day. Then I took the amount of heart beats and divided it by 1440 so we know how many full days. This is what the equation would look like: 748,800/1440.

A company makes a profit of $1.38 million. This is $2.54 million more than last year. Write and solve an equation to find the profit p (in millions of dollars) last year. An equation is =1.38.
Answer: Required equation : 1.38 = p +2.54
Last year profit = $ -1.16 million or we can say loss =$ 1.15 million
Step-by-step explanation:
Given : A company makes a profit of $1.38 million. This is $2.54 million more than last year.
Profit this year = 2.54 + Profit in last year
Let p = profit (in millions of dollars) last year.
Then, 1.38 = p +2.54 , is the required equation.
⇒ p = 1.38-2.54
⇒ p= -1.16, which is loss because of negative sign.
Hence, last year profit = $ -1.16 million or we can say loss =$ 1.15 million
Answer: The profit from 2021 = $ -1.16 Million ($1.16 Million loss)
Step-by-step explanation:
Profit for 2022 = $ 1.38 Million
Profit for 2021 = Profit for 2022 - $ 2.54 Million
Algebraic equation:
p2021 = p2022 -$ 2.54 Million
p2021 = $ 1.38 Million - $ 2.54 Million
p2021 = $ -1.16 Million

2(b + 2) = 40
O C.
3(b- 2) = 24
OD
2(8 + b) = 42
OE.
3(b - 4) = 20
Answer: C. 3(b-2)=24
Step-by-step explanation: See since b equals ten and by the rules of P.E.M.D.A.S the parenthesis/brackets comes first so 10-2 equals 8 and three times 8 is 24 therefore the answer is 24
