Answer:
x³ - 7x² + 4x + 30
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
x(x² - 2x - 6) - 5(x² - 2x - 6) ← distribute both parenthesis
= x³ - 2x² - 6x - 5x² + 10x + 30 ← collect like terms
= x³ - 7x² + 4x + 30

The number c is a _______ of the polynomial function yequals=P(x) if and only if xminus−c is a _______ of the polynomial P(x).
Answer:
"The number c is a zero the polynomial function y=P(x) if and only if x-c is a factor of the polynomial P(x)."
Step-by-step explanation:
We have been given some statements with blank spaces:
"The number c is a _______ of the polynomial function y=P(x) if and only if x-c is a _______ of the polynomial P(x)."
Now we need to fill those blank spaces by suitable words.
We know that if x=5 is some root (zero or solution) of the polynomial function then (x-5) works as factor.
So using that logic, we can fill the blanks spaces as:
"The number c is a zero the polynomial function y=P(x) if and only if x-c is a factor of the polynomial P(x)."
Answer:
I am 86% sure that it is The number c is zero the polynomial function y=P(x) if and only if x-c is a factor of the polynomial P(x)

Write the point-slope form of the line's equation satisfying the given conditions. Then use the point-slope form of the equation to write the slope-intercept form of the equation.
Passing through (negative 2,4) and (3,4)
Answer:
y = 4
or
y - 4 = 0(x - 3)
Step-by-step explanation:
The points (-2,4) and (3,4) have the same y-value. Because of this, the slope of the line will be 0 and the line will be horizontal. This means the line will have the equation y = b where b is the y-coordinate. The equation of the line is
y = 4.
In point slope form, the equation will have m = 0.
y - 4 = 0(x -3)
Please help!! I need ASAP 10 points <3

A) translated 9 units up and then reflected across the y-axis
B) translated 6 units to the right then translated 9 units up
C) translated 9 units to the right then translated 6 units up
D) translated 6 units to the right and then reflected across the x-axis
Answer:
B) translated 6 units to the right then translated 9 units up
Step-by-step explanation:
Just use the graph to follow each translation until you get thee right answer, or you can count how many spaces are from the pre-image to the image. Just make sure to always use the same point.
The transformation from figure A to figure A' are:
Translating 6 units to the right.
Translated 9 units up.
Option B is the correct answer.
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
We will take two coordinates from the figure.
Figure A has the coordinates:
(-5, -2) and (-4, -2)
And,
Figure A' has the coordinates:
(1, 7) and (2, 7)
Now,
Translating 6 units to the right.
(-5, -2) = (-5 + 6, -2) = (1, -2)
And,
(-4, -2) = (-4 + 6, -2) = (2, -2) _____(1)
Again,
Translated 9 units up.
(1, -2) = (1, -2 + 9) = (1, 7)
And,
(2, -2) = (2, -2 + 9) = (2, 7) ______(2)
From (1) and (2) we see that,
Figure A to Figure A'.
Translating 6 units to the right.
Translated 9 units up.
Thus,
The transformation from figure A to figure A' are:
Translating 6 units to the right.
Translated 9 units up.

Step-by-step explanation:
Part a) The drawn in the attached figure
Part b) What is the slant height of the outside edge?
we have that
The diameter of the base of the cone is 12 in
so
[tex]r=12/2=6\ in[/tex] ----> the radius is half the diameter
[tex]h=8\ in[/tex]
Applying the Pythagoras Theorem find the slant height x

A group of students are planning a mural at a wall the rectangular wall has dimensions of (6x+7) by (8x+5) and they are planning the mural to be (x+4) by(2x+5) what is the area of the remaining wall after the mural has been Painted
Answer: [tex]46x^2+73x+15[/tex]
Step-by-step explanation:
The area of a rectangle can be calculated with the formula:
[tex]A=lw[/tex]
l: the length of the rectangle.
w: the width of the rectangle.
The area of the remaning wall after the mural has been painted, will be the difference of the area of the wall and the area of the mural.
Knowing that the dimensions of the wall are [tex](6x+7)[/tex] by [tex](8x+5)[/tex], its area is:
[tex]A_w=(6x+7)(8x+5)\\\\A_w=48x^2+30x+56x+35\\\\A_w=48x^2+86x+35[/tex]
As they are planning that the dimensions of the mural be [tex](x+4)[/tex] by [tex](2x+5)[/tex], its area is:
[tex]A_m=(x+4)(2x+5)\\\\A_m=2x^2+5x+8x+20\\\\A_m=2x^2+13x+20[/tex]
Then the area of the remaining wall after the mural has been painted is:
[tex]A_{(remaining)}=A_w-A_m\\\\A_{(remaining)}=48x^2+86x+35-(2x^2+13x+20)\\\\A_{(remaining)}=48x^2+86x+35-2x^2-13x-20\\\\A_{(remaining)}=46x^2+73x+15[/tex]

Step-by-step explanation:
13x=7
It would be fractional
The equation to find the number of 13-foot pieces from a 7-foot piece of wood is explained step-by-step.
The equation to calculate the number of 13-foot pieces that can be cut from a 7-foot piece of wood is:
Number of pieces = Total length of wood / Length of each piece
Plugging in the values:
Number of pieces = 7 ft / 13 ft = 0.538 or approximately 0.54 pieces
Two planes left simultaneously from the same airport and headed in the same direction towards another airport 1800 km away. The speed of one of the planes was 100 km/hour slower than the speed of the other plane, and so it arrived at its destination 36 minutes after the faster plane. Find the speeds of both planes.
Answer:
Faster plane --> 600km/hr
Slower Plane --> 500km/hr
Step-by-step explanation:
Use inequality: 1800/r = 1800/(r-100) + 3/5 and solve to get r = 600, so the plane which is r -100 is 500 km/hr.

Rebecca has a credit line of $6,500. She had a previous balance of $398.64 and made a payment of $250. The total of her purchases is $1,257.99. What is Rebecca's available credit?
Answer:
$5093.37
Step-by-step explanation:
To get Rebecca's available credit we need to take all of her payments and purchases and previous balance.
Previous balance = $398.64
Purchases = $1,257.99
Payment = $250
Credit Line = $6,500
Now first we add together her purchases and previous balance.
398.64 + 1,257.99
This will give us:
$1,656.63 Total deductions.
Now we subtract that to her credit line.
$6500.00 - $1656.63
$4843.37
Now we take her payment and add it to her credit line.
$4843.37 + $250
$5093.37
So Rebecca's available credit is $5093.37.

Answer:
The answer is C because when you substituted the coordinate pairs into the equation, both sides are equal which tells you that they're a solution to the equation.
Explanation:
All you do is substitute. (x,y)
A:
Substitute
1 = 4(2) - 7
Multiply the number inside the parentheses by the outside number.
1 = 8 - 7
Subtract to get your solution.
1 = 1
Both sides equal to each other so this means that this is a solution to the equation.
B:
Substitute
9 = 4(4) - 7
Multiply the number inside the parentheses by the outside number.
9 = 16 - 7
Subtract to get your solution.
9 = 9
Both sides equal to each other so this means that this is also a solution to the equation.
D:
Both ordered pair is a solution to the equation.

if you dig a 12 feet hole and you cover up that hole how deep is that hole
Answer:
If your definition of "Cover" is to fill it in, than there is no longer a hole.
If your definition of "Cover" is to simply "cover" the hole and not filling it, there is still a 12 feet hole.
Unless your perspective is that there is no hole simply because it was Covered.
Step-by-step explanation: Try again

12y^2–5y=2
thank you!
answer Y=1 over 4 and Y= 2 over 3 that is your answer and these are the steps I'm going to put a image hope this is useful to u and have a beuty day
Answer:
f(y) = 12y^2 -5y -2 = 0
a = 12 b =-5 c=-2
Using quadratic formula:
y = [-b +-sq root (b^2 -4ac)] / 2 a
y = [--5 +-sq root (25 -4*12*-2)] / 24
y = [5 +- sq root (25 + 96) ] / 24
y = [5 +- sq root (121) ] / 24
y = [5 + 11] / 24
y1 = (2/3) = .66666666666
y2 = 5 -11 / 24
y2 = -(1/4) = -.25

Step-by-step explanation:
r^(-7) + s^(-12) can be re-written as
1 1
------ + ------- by putting to use the rule:
r^7 s^12
1
x^(-a) = ----------
x^a
For this case, we must simplify the following expression:
[tex]r ^ {- 7} + s ^ {- 12}[/tex]
By definition of power properties we have to:
[tex]a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}[/tex]
So, rewriting the expression we have:
[tex]\frac {1} {r ^ 7} + \frac {1} {s ^ {12}}[/tex]
Answer:
[tex]\frac {1} {r ^ 7} + \frac {1} {s ^ {12}}[/tex]
