If b(x) = negative2(xminus50), what is the value of b(20)?
Answer:
b(20) = 60
Step-by-step explanation:
Here, given that ;
b(x) = -2(x-50)
we want to find the value of b(20)
what we need to do is to simply substitute x for 20
That will be:
b(20) = -2(20-50)
b(20) = -2(-30)
b(20) = 60

Which expression could be used to determine the cost of a $50 video game after a 20 percent discount?
50 dollars (0.20)
50 dollars minus left-bracket (50 dollars) (0.08) right-bracket
50 dollars minus 0.80
50 dollars (0.80). please a b c or d?
Answer:
d
Step-by-step explanation:
to find a discount you would multiply 50(0.20) whatever amount you get you would subtract that from 50
this is the same as 50(0.80)

Answer:
x = 7 or x = -8
Step-by-step explanation:
3|2x + 1| = 45
Divide both sides by 3.
|2x + 1| = 15
Separate into a compound equation.
2x + 1 = 15 or 2x + 1 = -15
2x = 14 or 2x = -16
x = 7 or x = -8

6. y) - (x+3)

D. (.y)-( y. x+3)
C
Given:
Consider triangle ABC is rotated 90 degrees counterclockwise and then translated 3 units up to form triangle A'B'C'.
To find:
The transformation that can be used to map each point (x,y) on Triangle ABC to its corresponding point on Triangle A'B'C'.
Solution:
If a figure rotated 90 degrees counterclockwise, then
[tex](x,y)\to (-y,x)[/tex]
[tex]P(x,y)\to P_1(-y,x)[/tex]
If a figure translated 3 units up, then
[tex](x,y)\to (x,y+3)[/tex]
[tex]P_1(-y,x)\to P'(-y,x+3)[/tex]
If triangle ABC is rotated 90 degrees counterclockwise and then translated 3 units up to form triangle A'B'C', then the rule of transformation is
[tex](x,y)\to (-y,x+3)[/tex]
Therefore, the required rule of transformation is [tex](x,y)\to (-y,x+3)[/tex].
Note: Option are not in proper form.
All the points of the triangle ABC(assuming it is in first quadrant) of the form (x,y) turns (-x,y+3) after applying considered transformations.
How does rotation by 90 degrees changes coordinates of a point if rotation is with respect to origin?Let the point be having coordinates (x,y).
Case 1: If the point is in first quadrant:Subcase: Clockwise rotation:
Then (x,y) → (x, -y)
Subcase: Counterclockwise rotation:
Then (x,y) → (-x, y)
Case 2: If the point is in second quadrant:Subcase: Clockwise rotation:
Then (x,y) → (-x, y)
Subcase: Counterclockwise rotation:
Then (x,y) → (x, -y)
Case 3: If the point is in third quadrant:Subcase: Clockwise rotation:
Then (x,y) → (x, -y)
Subcase: Counterclockwise rotation:
Then (x,y) → (-x, y)
Case 4: If the point is in fourth quadrant:Subcase: Clockwise rotation:
Then (x,y) → (-x, y)
Subcase: Counterclockwise rotation:
Then (x,y) → (x, -y)
Case 5: For points on axesYou can take that point in any of the two surrounding quadrants. Example, if the point is on positive x axis, then it can taken as of first quadrant or fourth quadrant.
Case 6: On originNo effect as we assumed rotation is being with respect to origin.
Since no quadrant is specified, we assume triangle is fully in first quadrant. That means all points (x,y) will turn (-x,y) after counter clockwise rotation.
Now translation of 3 units up means all y coordinates will be increased by 3, thus, all (x,y) points of triangle first become (-x,y) then (-x, y+3).
Thus, all the points of the triangle ABC(assuming it is in first quadrant) of the form (x,y) turns (-x,y+3) after applying considered transformations.

Which statement is true about the equations –3x + 4y = 12 and 1 x - y = 1?
O The system of the equations has exactly one solution at (-8, 3).
O The system of the equations has exactly one solution at (-4, 3).
The system of the equations has no solution; the two lines are parallel.
O The system of the equations has an infinite number of solutions represented by either equation.
Answer:
None of these answers is trueStep-by-step explanation:
1x - y = 1 ⇒ x - 1 = y
-3x + 4y = 12
-3x + 4(x - 1) = 12
-3x + 4x - 4 = 12
x - 4 = 12
x = 16 ⇒ 16 - 1 = y ⇒ y = 15
Therefore the system of the equations has exactly one solution at (16,15)
Answer:
D- There are infinite solutions
Step-by-step explanation:
-3x + 4y= 12 is the same as 1/4x -1/3y = 1.
1/4x multiplied by 12 is 3x
-1/3y multiplied by 12 is -4y
To flip the negatives you multiply by -1 to get -3x + 4y+ 12 on both equations

The range includes all numbers from 5 to 12.5.
The range includes all integers between 0 and 12.5.
The range includes all numbers from 0 to 8.5.
The range includes all numbers from 0 to 12.5.
Answer:
The range includes all numbers from 5 to 12.5.
Step-by-step explanation:
The range is along y- axis and the domain is along x- axis.
Range is given in heights and domain is given in time seconds.
It can depicted that for t= 0 secs the ball is at 5 feet and so on .
Therefore the range is given by numbers from 5 to 12.5.
Whereas the domain is given by numbers 0 t0 8.5 seconds
The range is the values of 'y' and the domain is the values of 'x'. So, the range of the includes all numbers between 5 and 12.5 and the domain includes all numbers between 0 and 8.5.
Given :
A child tosses a baseball up into the air. On its way down, it gets caught in a tree for several seconds before falling back down to the ground.
The graph attached below shows the given scenario that "A child tosses a baseball up into the air. On its way down, it gets caught in a tree for several seconds before falling back down to the ground".
The y-axis shows the height of the ball in feet from the ground and the x-axis shows the time in seconds.
The range is the values of 'y' and the domain is the values of 'x'. So, the range of the includes all numbers between 5 and 12.5 and the domain includes all numbers between 0 and 8.5.
Therefore, the correct option is A) The range includes all numbers from 5 to 12.5.
