The coordinates of J are (-12,1)

J(-7,-3) is the image of J after a translation along the vector (-5,4). What

To find the coordinates of J.

J(-7,-3), (-5,4)

J(-7-5, -3+4)= (-12,1)

Hence, The coordinates of J are (-12,1).

Coordinates are a pair of numbers that identify a specific point on a coordinate plane, which is a grid of integers. A point in a plane has specific coordinates, as we are aware.

Any point's location on a plane can be described by an ordered pair of values (x, y), which are referred to as coordinates. In our daily lives, we employ coordinates for things like map locations and in-class seating arrangements.

The cartesian coordinate system is used to find a point's location in a plane. The idea of two axes that are mutually perpendicular is used to represent a point's coordinate. In the two-dimensional plane, points are represented as an ordered pair of x and y coordinates, denoted as (x,y).

Associate the average of the numbers from 1 to n (where n is a positive integer value) with the variable avg.
Kaylis [27]
This is a simple programming question. To calculate the average of any two numbers, where one number is 1 and the other is n, simply add the two numbers and divide by 2. Therefore, the answer is:
<span>avg = (1 + n) / 2</span>

Kelko will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $57 and cost an add
Delicious77 [7]

Questions (contd)

(a) For what amount of driving do the two plans cost the same?

(b) What is the cost when the two plans cost the same?

Answer:

(a) 100 miles

(b) $65

Step-by-step explanation:

Given

Plan 1:

Initial\ Fee = \$57

Additional = \$0.08 per mile

Plan 2:

Initial\ Fee = \$50

Additional = \$0.10 per mile

Solving (a): Number of miles when both plans are equal

Represent the distance with x and the cost with y

So:

Plan 1:

y = 57 + 0.08 * x

Plan 2:

y = 50 + 0.10 * x

To solve (a), we equate both plans together; i.e.

y = y

57 + 0.08x = 50 + 0.10x

Collect Like Terms

0.08x - 0.10x= 50 - 57

-0.02x= -2

Solve for x

x = -2/-0.02

x = 100

Hence, 100 mile would cost both plans the same

Solving (b): Cost when both plans are the same:

In this case, we simply substitute 100 for x in any of the y equation.

y = 57 + 0.08 * x

y = 57 + 0.08 * 100

y = 57 + 8

y = 65

<em>Hence, the amount is $65</em>

Find the length and width of a rectangle whose perimeter is
Hoochie [10]

Answer:

11 and 7

Step-by-step explanation:

Perimeter is all of the sides added together

11+11+7+7=36

Area of a rectangle is length x width

7*11=77

The answers are 7 and 11 for the length and width

Whether which one is the width and which is the length depends on which side is the longest.

What is an equation of the line that passes through the points (4,-1) and (8,5)?
fiasKO [112]

Answer:

y=3/2x-7

Step-by-step explanation:

the equation of the line for slope-intercept form is y=mx+b, where  m is the slope and b is the y intercept.

we are given two points: (4,-1) and (8,5)

the equation for slope is (y2-y1)/(x2-x1)

label the points:

x1=4

y1=-1

x2=8

y2=5

now substitute into the equation:

m=(5--1)/(8-4)

m=6/4

m=3/2

the slope of the line is 3/2

here is our equation so far:

y=3/2x+b

we need to find b

since the equation will pass through the points, we can substitute either one into the equation to find b

let's use (4,-1) as an example

substitute into the equation

-1=3/2(4)+b

-1=6+b

-7=b

the y intercept is -7

so the equation is y=3/2x-7

hope this helps!
