Answer:
Take f(x) to be 4x^3-5x^2-4x-4Take g(x) to be 5x^2+xThen proceed to do f(x)/g(x)Perform synthetic or long division (which ever is your preferred method) Your remainder will be whatever is left over at the end of the division and the quotient will be the first variables.Jerry has a part-time job at a supermarket. The ordered pairs show the number of hours he worked for (input values) and the number of dollars (output values) he earned over a five week period. (6,72) (8,96) (5.5, 66) (9,108) (7,84) Are the ordered pairs a relation?
Answer:
Yes
Step-by-step explanation:
The ordered pairs are (6,72) (8,96) (5.5, 66) (9,108) (7,84).
The number of hours worked is [tex]x[/tex] and the money earned is [tex]y[/tex].
Let us divide the values of [tex]y[/tex] by [tex]x[/tex]
[tex]\dfrac{72}{6}=12[/tex]
[tex]\dfrac{96}{8}=12[/tex]
[tex]\dfrac{66}{5.5}=12[/tex]
[tex]\dfrac{108}{9}=12[/tex]
[tex]\dfrac{84}{7}=12[/tex]
The fuction which defines the above ordered pairs is [tex]y=12x[/tex]
It can be seen that the amount of money earned is 12 times the number of hours worked.
So, per hour Jerry earns 12 dollars.
Hence, the ordered pairs are relation.

Please help me circles.....
Answer:
95
Step-by-step explanation:
The equation is
x×2=285-x
3x=285
x=95
Answer:
x = 75°
Step-by-step explanation:
There are many Circle Geometry Rules. We will be using the following:
The angle at the centre of the circle is twice the angle at the circumference.
x = the angle opposite 285 - x.
This means that 360 - (285 - x) = 2x
360 - 285 + x = 2x
75 + x = 2x
We can simplify this by taking away x from both sides.
75 = x
We can check this by substituting x into the orginal equation.
360 - (285 - x) = 2x
360 - (285 - 75) = 2 * 75
360 - 210 = 2 * 75
150 = 2*75
150 = 150

find value of following : 2sin75°.cos15°
Answer:
[tex]\frac{2+\sqrt{3} }{2}[/tex]
Step-by-step explanation:
Using the product to sum formula
sinxcosy = [tex]\frac{1}{2}[/tex] [ sin(x + y) + sin(x - y) ] , then
2sinxcosy = sin(x + y) + sin(x - y)
Given
2sin75°cos15° ← with x = 75 and y = 15 , then
= sin(75 + 15) + sin(75 - 15)
= sin90° + sin60°
= 1 + [tex]\frac{\sqrt{3} }{2}[/tex]
= [tex]\frac{2+\sqrt{3} }{2}[/tex]
Can you solve this by explaining.
Answer:
The answer is 1
Step-by-step explanation:
Start by solving the division part of the equation. In order to do that, you have to flip the fraction (reciprocal) and switch from division to multiplication, thus getting 3 x 3 = 9. Now you have 9 – 9 + 1, and from there you can simply work from left to right and get your final answer: 1.

Answer:
The value of x is 20 ⇒ A
Step-by-step explanation:
When a line intersects two parallel lines, then some pairs of angles are formed
Alternate interior angles which equal in measuresAlternate exterior angles which equal in measuresCorresponding angles which equal in measuresAdjacent interior angles which are supplementary (the sum of their measures is 180°)In the given figure
∵ Lines l and m are parallel
∵ They are intersected by a line
∴ The angles of measures (3x + 5)° and 65° are alternate interior angles
→ That means they are equal in measures
∵ Alternate interior angles are equal in measures
∴ (3x + 5)° = 65°
→ Subtract 5 from both sides
∵ 3x + 5 - 5 = 65 - 5
∴ 3x = 60
→ Divide both sides by 3
∴ x = 20
∴ The value of x is 20

PLEASEEEEE HELPPPPPPPPPP
9514 1404 393
Answer:
p(x) = x^3 +x^2 -82x +80
Step-by-step explanation:
If a polynomial function has a zero at x=a, then (x -a) is a factor. Your list of zeros means the factors are ...
p(x) = (x -8)(x +10)(x -1) . . . . . . . . factored form
When this is multiplied out, it becomes ...
p(x) = x^3 +x^2 -82x +80 . . . . . . standard form
_____
The factored form can be multiplied out using the distributive property.
= ((x(x +10) -8(x +10))(x -1)
= (x^2 +10x -8x -80)(x -1)
= (x^2 +2x -80)x -(x^2 +2x -80)
= x^3 +2x^2 -80x -x^2 -2x +80
= x^3 +x^2 -82x +80

Josie has $30 to spend at a festival .It cost $5 to enter the festival and the game she wants to play cost $1.40 .Write the inequality and use it to determine the number of games that Josie can play
Answer:
At the maximum Josie can be 17 games.
Step-by-step explanation:
Given that:
Total money available with Josie to be spent at a festival = $30
Entry ticket for the festival = $5
Ticket for each game = $1.40
To find:
The inequality to represent the situation and the number of games that Josie can play.
Solution:
Ticket for 1 game = $1.40
Let [tex]n[/tex] number of games can be played.
So, Ticket for [tex]n[/tex] games = $1.40[tex]n[/tex]
Total money spent = $1.40[tex]n[/tex] + $5
It is should be lesser than or equal to $30.
[tex]1.40n + 5 \leq 30\\\Rightarrow 1.40n \leq 25\\\Rightarrow n \leq 17.8[/tex]
Therefore, at the maximum Josie can be 17 games.

Evaluate the expression 15g if g = 1/5.
Answer:
3
Step-by-step explanation:
15g
g=1/5
15×1/5
15/1×1/5=3
Answer:
3
Step-by-step explanation:
This is the answer because:
1) We have to substitute the value into the equation:
15(1/5)
2) Next, we have to mutiply 15 and 1/5 together since the g is just a variable that is supposed to be mutiplied with 15:
15(1/5) = 15/5 = 15 ÷ 5 = 3
Therefore, the answer is 3.

f the line with equation y=−2x+7 is rotated 90° clockwise about the origin, what are the coordinates of the image of its y-intercept?
A. (2,0)
B. (7,0)
C. (0,−7)
D. (−7,0)
Answer:
B
Step-by-step explanation:
I looked it up
The line with equation y=−2x+7 is rotated 90° clockwise about the origin, the coordinates of the image of its y-intercept is D (−7,0).
What is y-intercept of a function?The intersection of the graph of the function with the y-axis gives y-intercept of that function.
The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Assume that we've got: y = f(x)
At y-axis, we've got x = 0, so putting it will give us the y-intercept.
Thus, y-intercept of y = f(x) is y = f(0)
To find the y-intercept of the line y=-2x+7. When x=0 we have that y=-2·0+7, y=7,
then point (0,7) is the y-intercept.
When we rotate this line 90° clockwise about the origin, then point (0,7) will be placed on the x-axis in positive x-direction.
Rotation preserves the distances, then the coordinates of the image are (7,0).
The correct choice is D (−7,0).
