Make the two equations equal together and solve for x
(x/3) = -2x+7 
multiple both sides by 3
x=-6x+21
solve for x
7x=21
x=3.
now plug in 3 into one of the equation to find your y value. 
y=-2(3)+7
y=1
write your answer as a coordinate; (3,1)

The ratio 400g:1kg can be written in the form 1:n<br> Find the value of n
nirvana33 [79]

Answer:

n = 0.0025

Step-by-step explanation:

400g —————> 1kg

Then

400g —————> 1000g

or 1000/400 = 2.5 ⇔ 400 × 2.5 = 1000

Then

1g ———————> 2.5 × 1 = 2.5g = 0.0025kg

The coordinates (-2, -2.5) and  (-1, -1) are satisfying the equation so pairs (A) and (B) will be correct.

<h3>What is the equation?</h3>

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.

A formula known as an equation uses the same sign to denote the equality of two expressions.

In another word, the equation must be constrained with some constraints.

Given the equation,

3x= 2y - 1

To know which coordinate satisfies the equation we need to put one by one all three coordinate,

Coordinate (A) ⇒ A) (-2, -2.5)

3(-2) = 2(-2.5) - 1 ⇒ -6 = -6 so it is satisfying.

Coordinate (B) ⇒ B) (0, -0.5)

3(0) = 2(-0.5) - 1 ⇒ 0 ≠ -2 so it is not satisfying.

Coordinate (C) ⇒C) (-1, -1)

3(-1) = 2(-1) - 1 ⇒ -3 = -3 so it is also satisfying.

Hence "The pair (-2, -2.5) and  (-1, -1) are satisfying".

Given a normally distributed data set with the mean = 88 and the standard deviation = 6, according to the empirical rule, what p
kumpel [21]

According to the empirical rule, the percent of the data points that are below 100 is; 95.44%

<h3>How to use Empirical Rule in Statistics?</h3>

We are given;

Mean; μ = 88

Standard deviation; σ = 6

Sample mean; x' = 100

Formula for z-score is;

z = (x' -  μ)/σ

z = (100 - 88)/6

z = 2

Now, from the empirical rule of normal distribution graph attached, we see that at z = 2, the percentage is 95.44%. However, we want to find the percentage that lie below 100. Thus, this is 95.44%
