Answer:
A rectangle on a coordinate plane is translated 5 units up and 3 units to the left.
3) O(x,y)=(x-3,y+5)
The rule that describes the translation is (x, y) -> (x - 3, y + 5), the correct option is C.
How does transformation of a function happens?The transformation of a function may involve any change.
Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units:
y=f(x+c) (same output, but c units earlier)
Right shift by c units:
y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y =[tex]k \times f(x)[/tex]
Horizontal stretch by a factor k: y = [tex]f\left(\dfrac{x}{k}\right)[/tex]
We are given that;
5 units up and 3 units to the left
Now,
In this case, the rectangle is translated 5 units up and 3 units to the left. This means that the vertical shift is 5 and the horizontal shift is -3.
After transformation x=x - 3
Y=y + 5
Therefore, the transforming function will be (x, y) -> (x - 3, y + 5).

What proportion represents the percent of
strike outs per at bats?
Answer:
p = 31.19%
Step-by-step explanation:
Proportions and Percentages
A proportion is calculated as a division between two numbers. The result can be given as a decimal or as a percentage.
If we want to calculate the percent of a number N with respect to another number M, the formula is:
[tex]\displaystyle p=\frac{N}{M}*100\%[/tex]
Eli had some performances when playing baseball. Struck out 25 times in 75 times at bat, 30 times in 100 at-bats, and 37 times in 120 at-bats.
The total struck outs were: N= 25+30+37=92 and the total at-bats were: 75+100+120=295. The proportion of strikeout ber at-bats is:
[tex]\displaystyle p=\frac{92}{295}*100\%[/tex]
p = 31.19%

The function y= x2 - 10x+ 31 has a
value of
Answer:
y = 6 at x = 5Step-by-step explanation:
It is assumed the question is about finding the minimum value as the given function has no maximum value, it is + ∞ as the coefficient of x² is positive
The minimum/maximum value of a quadratic function is the vertex, which is at:
x = -b/2aFor the given function y = x² -10x + 31, the vertex is:
x = - (-10)/2*1 = 10/2 = 5The value of y at this point is:
y = 5² - 10*5 + 31 = 25 - 50 + 31 = 6The point is
(5, 6)To gather information on customer satisfaction, a researcher randomly selects four store locations and interviews all the customers at those selected stores. This sampling technique is called:
Answer:
This sampling technique is called cluster
Step-by-step explanation:
Samples may be classified as:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this question:
The population is divided into groups(by stores), and all elements of the groups(all customers at the stores are sampled), which is the characteristic of a cluster sampling.

324=4(3)2x
a. x=8
b. x=4
c. x=2
d. x = 1
Answer
C. x=2
Step-by-step explanation:
This is due to 2(2) = 4
then 3^4=81
81*4=324
The solution to equation [tex]324=4(3)^{2x}[/tex] is x = 2.
What is exponential function?An exponential function is a mathematical function of the following form:
[tex]f(x) = a^{x}[/tex]. where x is a variable, and a is a constant called the base of the function.
Given exponential equation
[tex]324=4(3)^{2x}[/tex]
[tex]4(3)^{2x}=324[/tex]
[tex]3^{2x} =\frac{324}{4}[/tex]
[tex]3^{2x}=81[/tex]
[tex]3^{2x}=3^{4}[/tex]
When bases are equal, power should be equal.
2x = 4
x = 2
Hence, the solution to equation [tex]324=4(3)^{2x}[/tex] is x = 2.
Option C is correct.

The system of equations y=-2x+3 and y=x is graohed. What is the solution to the system of equations
Answer:
The solution to this system of equations is y = 1, x = 1
Step-by-step explanation:
We know that...
(1) y = - 2x + 3
(2) y = x
Then we just substitute the value of x that we are given in equation (2).
And so we get....
y = -2x + 3
x = - 2x + 3
3x = 3
x = 1
From equation (2) we know that y = x, so since x equals 1 y is also 1. There for the solution to this system of equations is (1,1)

The question is incomplete. Here is the complete question.
m∠J and m∠Kare base angles of an isosceles trapezoid JKLM.
If m∠J = 18x + 8, and m∠M = 11x + 15 , find m∠K.
A. 1
B. 154
C. 77
D. 26
Answer: B. m∠K = 154
Step-by-step explanation: Isosceles trapezoid is a parallelogram with two parallel sides, called Base, and two non-parallel sides that have the same measure.
Related to internal angles, angles of the base are equal and opposite angles are supplementary.
In trapezoid JKLM, m∠J and m∠M are base angles, so they are equal:
18x + 8 = 11x + 15
7x = 7
x = 1
Now, m∠K is opposite so, they are supplementary, which means their sum results in 180°:
m∠J = 18(1) + 8
m∠J = 26
m∠K + m∠J = 180
m∠K + 26 = 180
m∠K = 154
The angle m∠K is 154°
Find x if:
- B is between A & C;
-AB = x + 5;
-BC = 2(x-3); and
-AB ~= BC
Answer:
The value of x = 11
Step-by-step explanation:
Given
B is between A and C.AB = x+5BC = 2(x - 3)[tex]{\displaystyle {\overline {AB}[/tex] ≅ [tex]{\displaystyle {\overline {BC}[/tex]Determining the value of x
As B is between A and C, so
[tex]{\displaystyle {\overline {AB}[/tex] ≅ [tex]{\displaystyle {\overline {BC}[/tex]
as
AB = x+5BC = 2(x - 3)so
x + 5 = 2(x-3)
x+5 = 2x-6
2x-x = 5+6
x = 11
Therefore, the value of x = 11

Cheryl is buying lace for her dance costume. One foot of lace costs 3 dollars. How much does each amount cost?
3/4 of a foot?
Answer:
3/4 of a foot will cost $2.25.
Step-by-step explanation:
This question is solved by rule of three, due to proportions.
One foot of lace costs 3 dollars. How much is 3/4 of a foot going to cost?
1 foot - 3 dollars
3/4 foot - x dollars
[tex]x = 3 \times \frac{3}{4} = \frac{9}{4} = 2.25[/tex]
So
3/4 of a foot will cost $2.25.
