<h2>Linear equations</h2><h3>Concept</h3>

Linear equations, or a straight line on a graph, generally consist of two variables, x, and y - as well as slope.

<h3>Utilization</h3>

You have been provided a linear equation in slope-intercept form (y=mx+b). Let's look at the true and false statements now:

The graph of the equation is the set of all points that are solutions to the equation, TRUE or FALSE. The answer to this is true, because any point on the line should provide a valid solution to the problem. TRUE

The point (10, 3) is on the graph of the equation. We have already determined that in order for a point to be on the line - it must be a solution... so, plug it in and test:

y = 12x - 2\\3 = 12(10) - 2\\3 = 120 - 2\\3 = 118

3 is not equal to 118, so the point (10,3) is not on this line. FALSE

The point (−2,−1) is on the graph of the equation. Use the same setup as before:

y = 12x - 2\\-1 = 12(-2) - 1\\-1 = -24 - 1\\-1 = -25

-1 is not equal to -25, so this point is once again, not on the line. FALSE

The graph of the equation is a single point representing one solution to the equation. This is nearly the inverse of the first statement, so we can rule this out as well. FALSE

<h3>Answer</h3>

The only true statement here seems to be The graph of the equation is the set of all points that are solutions to the equation. Hope this helps you!

explain how you would find how many 1 1/2 cup servings there are in a pot that contains 22 1/2 cups of soup.
11Alexandr11 [23.1K]

Step-by-step explanation:

multiply the 1 1/2 by 2 to get 3.

find the closest number that is divisible by 3

3*7 is 21.

We now have to multiply 7 by 2 since we did that to our mixed number to get a whole number.

There is still a 1 1/2 left over. Simply add 1 to 14.

Jakobe runs a coffee cart where he sells coffee for $1.50 tea for $2 , and donuts for $0.75 . On Monday, he sold 320 items and m
Andreyy89

Jakobe sold 150 coffee, 50 tea and 120 donuts at the coffee cart on Monday.

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

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the amount of coffee, y represent the amount of tea and z represent the amount of donuts, hence:

x + y + z = 320    (1)

Also:

1.5x + 2y + 0.75z = 415     (2)

And:

x = 3y     (3)

From the equations:

x = 150, y= 50 and z = 120

Jakobe sold 150 coffee, 50 tea and 120 donuts at the coffee cart on Monday.

Solve y′′=sin(x) if y(0)=0 and y′(0)=5.<br><br> y(x)=?
Ksenya-84 [330]

Answer:

y(x)=6x-sin(x)

Step-by-step explanation:

Rewrite the differential equation as:

\frac{d^{2} y }{dx^{2} } =sin(x)

Integrate both sides with respect to x:

\int\ \frac{d^{2} y }{dx^{2} } dx = \int\ sin(x) dx

\frac{dy}{dx} =-cos(x)+C_1

Integrate one more time both sides with respect to x:

\int\ \frac{dy}{dx} = \int\ -cos(x)+C_1 dx

y(x)=-sin(x)+C_1x+C_2

Now that we find the solution, let's find its derivate:

y'(x)=C_1-cos(x)

Evaluating the initial conditions:

y(0)=C_1(0)+C_2-sin(0)=0\\C_2=0

y'(0)=C_1-cos(0)=5\\C_1=5+1=6

Replacing the value of the constants that we found in the differential equation solution:

y(x)=6x-sin(x)
