What is the image point of (-4, 8) after a translation right 4 units and up 2 units?
Answers
Given:
Point = ( -4,8).
To find:
The image point of (-4, 8) after a translation right 4 units and up 2 units.
Solution:
We know that, if a figure translated 4 units right and 2 units up, then the rule of translation is
[tex](x,y)\to (x+4,y+2)[/tex]
The point is (-4,8).
Putting x=-4 and y=8, we get
[tex](-4,2)\to (-4+4,8+2)[/tex]
[tex](-4,2)\to (0,10)[/tex]
Therefore, the image of point (-4,8) is (0,10).

Answers
Answer:
1/7
Step-by-step explanation:
Given that:
Using a scale factor of 7 ; the dimension of a rectangle is : 2 inches by 3 inches
In other to obtain the original size of the rectangle, all that is needed is to multiply the sacl d dimension by the reciprocal of the initi. Scale factor used, that is 1 / 7
This gives :
(2 inches by 3 inches) * 1/7
2/7 inches by 3/7 inches
Hence, required scale factor is 1/ 7

The total amount an aerobics teacher makes for teaching x number of students can be represented by the function T(x)=4x. If T(25)=100, then teaching ____ students makes the teacher ____$
Answers
Answer:
Teaching 25 students makes the teacher 100 dollars.
======================================================
Explanation:
The notation T(25) means "The value of T(x) when x = 25".
The instructions state that x represents the number of students. So x = 25 means the teacher has 25 students.
Writing T(25) = 100 means the teacher earns $100 from teaching 25 students.
We could also write T(x) = 100 when x = 25. Though it's more compact to say T(25) = 100.
--------------------------
Note that,
T(x) = 4x
T(25) = 4*25 ... replace x with 25
T(25) = 100
As you can probably see by now, each student pays $4 which is what leads to the $100 total.

Mr. Smith goes to the concession stand and buys 2 soft pretzels and 1 cheeseburger for $8.25. Mr. Martin goes to the same concession stand and buys 1 soft pretzel and 3 cheeseburgers for $13.50. Write a system of equations and solve to determine the cost of a cheesburger.
Answers
Answer:
$4.15
Step-by-step explanation:
Let the cost of a cheeseburger be x
Let the cost of a soft pretzels be y
If Mr. Smith goes to the concession stand and buys 2 soft pretzels and 1 cheeseburger for $8.25, this is expressed as;
x + 2y = 8.25 .... 1
Also, if Mr. Martin goes to the same concession stand and buys 1 soft pretzel and 3 cheeseburgers for $13.50, this is expressed as;
3x + y = 13. 50..... 2
The required equations are:
x + 2y = 8.25
3x + y = 13. 50
Find x and y by solving simultaneously:
From 1: x + 2y = 8.25
x = 8.25 - 2y ..... 3
Substitute 3 into 2
3(8.25-2y)+y = 13.50
24.75 - 6y+y = 13.50
24.75 - 5y = 13.50
-5y = 14.50 - 24.75
-5 y = 10.25
y = -10.25/-5
y = 2.05
Since x = 8.25 - 2y
x = 8.25 - 2(2.05)
x = 8.25 - 4.1
x = 4.15
Hence the cost of a cheesburger is $4.15

Answers
Answer:
3/8
Step-by-step explanation
A composite number is a positive integer that can be formed by multiplying two smaller positive integers. So 4,6,and 8 would be composite numbers. There's 8 numbers in total so 3/8.
The theoretical probability of the given event with one spin would be,
⇒ P(a composite number) = 3/ 8
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
We have to given that;
The spinner is used in a game.
Here, There are three (4, 6, 8) composite number.
And, Total numbers = 8
Hence, The theoretical probability of the given event with one spin would be,
⇒ P(a composite number) = 3/ 8
Thus, The theoretical probability of the given event with one spin would be,
⇒ P(a composite number) = 3/ 8
