Given the quadrilateral ABCD with vertices A(1, 1), B(2, 3), C(4, 3) and D(5, 1)
What are the coordinates of each point after quadrilateral ABCD is rotated 270° about the origin?
Answers
Answer:
A (1,1) becomes (-1,1)
B (2,3) becomes (-3,2)
C( 4,3) becomes (-3,4)
D(5,1) becomes (-1,5)
Step-by-step explanation:
By rotation around the origin at the given degree;
Given it is a clockwise rotation;
(x,y) becomes (-y,x)
A (1,1) becomes (-1,1)
B (2,3) becomes (-3,2)
C( 4,3) becomes (-3,4)
D(5,1) becomes (-1,5)
Which ordered pair is the solution to the system
equations?
5 -5x – 3y = 12
1 = 0
y = X – 12
Which ordered pair is the solution to the system of equations?
Answers
Answer:
2 ordered pairs are solutions:
(1, -11) and (3, -9)
Step-by-step explanation:
The pairs (1, -11) and (3,-9) are the solution to the system of equations.
What are the roots of an equation?Roots of an equation are the solution of that equation since an equation consists of hidden values of the variable to determine them by different processes and then the resultant is called roots.
For example root of x -4 = 0 is x = 4 so 4 will be the only root of this linear equation.
If any coordinate or point is satisfy an equation then it will be solution of that equation.
Taking y = x - 12
If we keep all points one by one then we get to know that,
Point (1,11) and (3,-9) are satisfying;
(1, -11) ⇒ -11 = 1 - 12 = -11
(3,-9) ⇒ -9 = 3 - 12 = -9
Hence "The pairs (1, -11) and (3,-9) are the solution to the system of equations".

point G is rotated 90°. the coordinate of the pre-image G was (7,-5), and it’s image G’ is at the coordinate (5,7). What is the direction of the rotation
Answers
Answer:
The Direction of the rotation is counterclockwise around the origin.
What was Given was that Point G is rotated 90°. The coordinate of the pre-image point G was (7, –5), and its image G’ is at the coordinate (5, 7).
What you need to find was : What is the direction of the rotation.
So coming to conclusions is we have given that Point G is rotated 90°.
The Pre-image of G = ( 7, -5).
Translated image G' = ( 5 ,7).
By the Rotation rule of 90° is : (-y, x) 90 degree rotation counterclockwise around the origin.
(y, -x) 90 degree rotation clockwise about the origin.
We can from G (7,-5) and G'( 5 ,7) it is rotation counterclockwise around the origin.
Therefore, Direction of rotation is counterclockwise around the origin.

Make a conjecture of what the x-intercepts of the function
f(x) = (2x - 1)(x + 3) will be.
Answers
Answer:
x=-3,x1/2
Step-by-step explanation:
f(x)=(2x-1)(x+3)
TI find x intercept/zero substitute
f(x)=0
0=(2x-1)x(x+3)
swap the sides of the equation
(2x-1)x(x+3)=0
when the product of factors equals 0,at least one factor is zero
2x-1=0
x+3=0
solve the equation for x
x=1/2
x+3=0
solve the equation of x
x=-3
The equation has two solution
x=-3
x=1/2

Step-by-step explanation:
Her taxable income is $ 43,000 which lies in the tax category $ 31,850 to
$ 77,100.
Tax for $ 31,850 is $ 4,386
Plus 25% of the amount = ( $ 43,000- $ 31,850 )= $ 11,150 over
25 % of $ 11,150= $ 2,787.5
Total Tax= $ 4386 + $ 2787.5= $ 7,173.5

EXPLAIN why the solution to the absolute value inequality | 4x - 9 | ≥- 12 is all real numbers.
Answers
Answer:
no matter what value you substitute for x, the absolute value will force the result to be a positive number and any positive number is greater than -12
Answer: Since the absolute value of any number is always greater than or equal to zero, then the given inequality holds for every real number.
Explanation: It doesn't matter which number you substitute for x, as the absolute value will convert the number into a positive one, which will always be greater or equal to 0. Hence, every real number can be a possible answer.
