The ordered pairs are (0,-7).
How Can an Ordered Pair Be Found?Any equation's ordered pair can be calculated by substituting any integer or the rational number for one of the variables, then solving for the remaining variable.
Consequently, we obtain values for both variables that meet the stated equation.
Solution:
5x - y = 7
Lets take, x = 0
Then,
5(0) - y = 7
y = -7
Then,
The ordered pair is (0,-7).

if the base of a rectangle is 12cm and the area is 345 cm², what is the height of the rectangle
Answers
Answer: 28.75 cm
Step-by-step explanation:
Using the formula for the area of a rectangle, we can plug in our known values and solve for the height.
A = B * H
(345 cm²) = (12cm) * H
28.75 cm = H

Answers
(-2, 4 1/2) (-1, 4) (0, 3 1/2) (1, 3) (2, 2 1/2) (3, 2)
Step by step
First I put our equation into y intercept form
2y = -1x + 7
Divide both sides by 2 to isolate y
2/2 y = -1/2x + 7/2
y = -1/2x + 3 1/2
Now we fill in your chart
From this we see the y intercept is at 3 1/2, so at (0, 3 1/2) is our coordinate on the y axis.
Enter this on your chart at 0x.
From here, we see our slope or rate of change is - 1/2 for every x value. So moving to the right from 0
3 1/2 + -1/2 = 3, (1, 3)
3 + -1/2 = 2 1/2 (2, 2 1/2)
2 1/2 + -1/2= 2 (3, 2)
Moving left from 0
3 1/2 - -1/2 = 4 (-1, 4)
4 - -1/2 = 4 1/2 (-2, 4 1/2)
Now you can graph your points

0 < - 27
Step-by-step explanation:
1. Distribute
3x + 6 < 3(x-7)
3x + 6 < 3x - 21
2. Subtract 6 from both sides
3x + 6 < 3x - 21
3x + 6 - 6 < 3x - 21 - 6
3. Simplify
subtract
3x + 6 - 6 < 3x - 21 - 6
3x < 3x - 21 - 6
subtract
3x < 3x - 21 - 6
3x < 3x - 27
4. Subtract 3x from both sides
3x < 3x - 27
3x - 3x < 3x - 27 - 3x
5. Simplify
combine like terms
3x - 3x < 3x - 27 - 3x

What is a coordinate system?A coordinate system is a method for determining how to place points or other geometrical objects on a manifold, such as Euclidean space, uniquely using one or more numbers, or coordinates.
how to locate Distance between two points?The length of the line segment bridging two locations in a plane is known as the distance between them. d=√((x2 – x1)² + (y2 – y1)²). is a typical formula for determining the separation between two places. Any two sites on an x-y plane or coordinate plane can have their distance between them calculated using this equation.
According to the given data:location of Arthur is (20, 30)
location of Jamie is (45, 60)
Let's apply the rule of distance to determine how far away they are because we know that :
d = √((X₂ - X₁)² + (Y₂ - Y₁)²)
let substituting the value we get:
d = √((X₂ - X₁)² + (Y₂ - Y₁)²)
d = √((45 - 20)² + (60 - 30)²)
= √(25)² + (30)²)
= 39.1

Phindi is an athlete . as part of her training, she runs around the outside of a circular track that has a radius of 88m. as part of her training, she has to run 12kmon the track. how many circuits of the track will she have to run?
Answers
It takes Phindi to run almost 22 tracks to cover 12kms
Given that,
First you have to figure out the length of the track whihc is circumference of circle ,
r is the radius of circular track which is 88m
The athlete has to run 12km on the track
Circumference of circle = 2πr
Solving circumference will give length of the circular track which is,
Circumference of circle = 2(3.14)(88)
=552.6 meters
If she covers 552.6 m whe runs one circular track then,
1 circular track -------- 552.6 meters
? circular track -------- 12000 meters or 12 kilometers
No of circular tracks = 12000/552.6 = 21.7 tracks
Therefore, It takes Phindi to run almost 22 tracks to cover 12kms

Answers
Answer:
x = 4 , x = 2.4
Step-by-step explanation:
[tex]\frac{4}{x-2}[/tex] + [tex]\frac{3}{x-3}[/tex] = 5
multiply through by (x - 2)(x - 3)
4(x - 3) + 3(x - 2) = 5(x - 2)(x - 3)
4x - 12 + 3x - 6 = 5(x² - 5x + 6)
7x - 18 = 5x² - 25x + 30 ( subtract 7x - 18 from both sides )
0 = 5x² - 32x + 48
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 5 × 48 = 240 and sum = - 32
the factors are - 20 and - 12
use these factors to split the x- term
0 = 5x² - 20x - 12x + 48 ( factor the first/second and third/fourth terms )
0 = 5x(x - 4) - 12(x - 4) ← factor out (x - 4) from each term
0 = (x - 4)(5x - 12)
equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
5x - 12 = 0 ⇒ 5x = 12 ⇒ x = 2.4

The given equation is

We want to test if x = 6 is a solution. We would substitute x = 6 into the equation. We have
5(6 - 3) = 6 + 13?
5(3) = 6 + 13?
15 = 19?
Since both sides of the equation is not equal, then
x = 6 is not a solution of the equation

Ashley is a software saleswoman. Her monthly salary is $2200 plus an additional $40 for every copy of math is fun she sells. Let S represent her total salary (In dollars), and let N represent the number of copies of math is fun she sells. Write an equation relating S to N and then graph your equation using the axes below
Answers
The equation of S in terms of N is S(N) = 2200 + 40N
How to determine the equation that relates S to NFrom the question, the given parameters are
Monthly salary = $2200
Additional earnings = $40 per copy of Math fun sold
The equation that relates S to N is then calculated as
Total = Monthly salary + Additional earnings x Number of copy of Math fun sold
Substitute the known values in the above equation
So, we have
S(N) = 2200 + 40N
So, the equation is S(N) = 2200 + 40N
