2) The coordinates of the vertices of quadrilateral ABCD are A(-1,8),
B(0,4), C(-2,1), and D(-4,3). Quadrilateral A'B'C'D' is the image of
quadrilateral ABCD after a rotation of 180° about the origin. State the
coordinates of the vertices of A'B'C'D'.
Answer:
The coordinates of vertices of A'B'C'D' are:
A'(1,-8), B'(0,-4), C'(2,-1) and D'(4,-3)
Step-by-step explanation:
When a point (h,k) is roated 180 degrees about the origin it becomes (-h,-k) which means that the new point after rotation is the negative of the previous.
Given vertices are:
A(-1,8), B(0,4), C(-2,1), and D(-4,3)
The new vertices will be:
[tex]A(-1,8) => A'(1,-8)\\B(0,4)=> B'(0,-4)\\C(-2,1)=> C'(2,-1)\\D(-4,3)=> D'(4,-3)[/tex]
The coordinates of vertices of A'B'C'D' are:
A'(1,-8), B'(0,-4), C'(2,-1) and D'(4,-3)
Percentage Questions
Answer:
At the end of three months, you will owe £767
Step-by-step explanation:
First you find 7% of 1000
= 70
70 is added to the £1000 every month so
1070 - 150 = 920
990 - 150 = 840
917 - 150 = 767
From 82 books to 138 books
Find the percent increase. Round to the nearest percent.
Answer:
68%
Step-by-step explanation:
Calculate percentage change
from V1 = 82 to V2 = 138
(V2−V1)|V1|×100
=(138−82)|82|×100
=5682×100
=0.682927×100
=68.2927%change
=68.2927%increase
=68%

Answer:
6.305
Step-by-step explanation:
Given
6 * 10° + 3 * 10^-1 + 5 * 10^-3
Required
Solve the expression
6 * 10° + 3 * 10^-1 + 5 * 10^-3
[Express 10° as 1]
So, we have:
= 6 * 1 + 3 * 10^-1 + 5 * 10^-3
= 6 + 3 * 10^-1 + 5 * 10^-3
Express the exponents as fraction.
= 6 + 3 * ⅒ + 5 * 1/10³
= 6 + 3 * ⅒ + 5 *1/1000
= 6 + 3/10 + 5/1000
Convert fractions to decimals
= 6 + 0.3 + 0.005
= 6.305
Hence, the result of the expression is 6.305

What is the value of y in the solution for this system of equations? 2x – 3y = 13 1 7. y = 5x - 2
The value of y in the solution for this system of equations is -61/13.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
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:
2x – 3y = 13 and y = 5x - 2
Solving the Two Equation we get
2x - 3(5x -2) = 13
2x - 15x + 6 = 13
-13x = 13 -6
-13x = 7
x= -7/13
and, y= 5(-7/13)- 2
y = -35/13- 2
y = -61/13

Answer:
9^8
Step-by-step explanation:
you multiply the exponents
-2(x+4)=12
please explain what to do .
Answer:
x = -10
Step-by-step explanation:
First I would expand by distributing the left side.
Using distribution the new equation would be: -2x - 8 = 12
Now, I would move constants to one side and keep variables on the other side.
Doing this, my new equation would be -2x = 20
Now I would divide both sides by negative 2, giving the answer x = -10

1. Dilate A using P as the center of dilation and a scale factor of 3. Label the new point
A'.
2. Dilate Busing Pas the center of dilation and a scale factor of 2. Label the new point B'
Answer:
Step-by-step explanation:
Rule for the dilation of a point by a scale factor 'k',
(x, y) → (kx, ky)
If we impose this rule in this problem,
k = [tex]\frac{\text{Distance of A' from P}}{\text{Distance of A from P}}[/tex]
1). If k = 3
Therefore, Distance of A' from P = 3(Distance of A from P)
And point A' will be on the third circle.
2). If k = 2
Distance of B' from P = 2(Distance of B from P)
Since, B is on circle 2, B' will be on circle 4.
Now we can plot these points A' and B' on the graph.
After the dilation point A becomes A' and it is at a distance of 3 units from point P and after the dilation point B becomes B' and it is at a distance of 2 units from point P.
1)
Given :
Dilate A using P as the center of dilation and a scale factor of 3.
Let the coordinates of point A be (x,y) then after dilation point A becomes A'(3x , 3y). So, the distance of the point A' from the point P is 3 units
2)
Given :
Dilate Busing P as the center of dilation and a scale factor of 2.
Let the coordinates of point B be (x',y') then after dilation point B becomes B'(2x' , 2y'). So, the distance of the point B' from the point P is 2 units

In a cafeteria, 5/8 of the students are eating salads, and 1/4 are eating sandwiches. There are 24 students in the cafeteria. How many students are eating lunches other than salads or sandwiches?
Answer:
Step-by-step explanation:
first, you would want to find the common denominator
3/8 (salads) = 3/8
1/4 (sandwiches) = 2/8
add them together to find out how much students and eating either salads or sandwiches
3/8 + 2/8 = 5/8
this means 5/8 of 24 students are eating either salads or sandwiches
24 students = 24/24 as a fraction
find the common denominator of 5/8 and 24/24
24/24 = 24/24
5/8 = 15/24
the final answer would be that 15 students out of 24 are eating a lunch other than a salad or sandwich
The number of people eating lunches other than salads or sandwiches is 3.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, In a cafeteria, 5/8 of the students are eating salads, and 1/4 are eating sandwiches.
So, The number of people eating salads is (5/8)×24 = 15.
And the number of people eating sandwiches is (1/4)×24 = 6.
Therefore, The number of people eating lunches other than salads or sandwiches is (24 - 15 - 6) = 3.

Find the equation of the circle with center at (3,-2) and radius of 3.
Answer:
The equation of the circle is (x - 3)² + (y + 2)² = 9
Step-by-step explanation:
The form of the equation of a circle is (x - h)² + (y - k)² = r², where
h is the x-coordinate center of the circlek is the y-coordinate of the center of the circler is the radius of the circle∵ The center of a circle is (3, -2)
∴ x-coordinate of the center is 3
∴ y-coordinate of the center is -2
∴ h = 3 and k = -2
∵ The radius of the circle is 3
∴ r = 3
→ Substitute them in the form of the equation above
∵ (x - 3)² + (y - -2)² = (3)²
∴ (x - 3)² + (y + 2)² = 9
∴ The equation of the circle is (x - 3)² + (y + 2)² = 9
