Solve the system of linear equations by substitution

Elodia [21]

X= 5y + 1

-2x + 9y = -1

-2(5y + 1) + 9y = -1

-10y - 2 + 9y = -1

-y - 2 = -1

-y = 1

y = -1

x + 5 = 1

x = -4

(-4, -1)

How do you find the y intercept when given points

tia_tia [17]

Answer:

On graph Y is vertical line and the intercept is where it matches x , as x is horizontal and always first to find. The usual equation to find x = 0 will always give you the y value in the given equation.

When the coffee is brewed according to directions, a pound of coffee beans yields 50 cups of coffee (4 cups = 1 qt). How many kg

Basile [38]

we know that

$1\ pound=0.453592\ kg$

in this problem

a pound of coffee beans yields $50$ cups of coffee

by proportion

Find the kg of coffee that are required to produce $100$ cups of coffee

$\frac{0.453592}{50}\frac{kg}{cups} =\frac{x}{100}\frac{kg}{cups}\\ \\50*x=100*.453592\\ \\x =0.453592*100/50\\ \\x=0.907184\ kg$

therefore

<u>the answer is</u>

$0.907184\ kg$

Three students are working to find the solution set of this system of equations: y = 3x + 10 2y = 6x – 4

ivanzaharov [21]

Answer:

Step-by-step explanation:

Since this is a system with two equations, we can easily use a graphing calculator to find the solution

The intersection between the graphs of the equations

y = 3x + 10

2y = 6x – 4 (if we divide by two)

y = 3x - 2

However, we can see that the graphs have the same slope m = 3

Since both equations are not equal, there is no solution for this system

Please see attached graph. The lines are parallel and they never touch each other.

What are the removable discontinuities of the following function? f (x) = startfraction x squared minus 36 over x cubed minus 36

Lyrx [107]

The removable discontinuity is at negative 6 and 6. Then the correct option is B.

<h3>What is a function?</h3>

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The function is given as

$f\rm (x) =\rm \dfrac{x^2-36}{x^3-36x}$

The expression can be written as

$f\rm (x) =\rm \dfrac{x^2-36}{x(x^2-36)}$

$f\rm (x) = \dfrac{1}{x}$

The non-removable discontinuity is x = 0.

More about the function link is given below.
