Answer:

Linear equations can take several forms, such as the point-slope formula, the slope-intercept formula, and the standard form of a linear equation. These forms allow mathematicians to describe the exact same line in different ways.

Answer:

(0,1)

Step-by-step explanation:

The zero of a function is where the answer is zero, so x=0 there. There's one point on this graph that has a point where x=0, and that is at y=1. Hope this helped :)

Answer:

157/ pi= 49.97 which is r squared, so the square root of 49.97= 7.06 or 7.1

so the radius of the rug is 7.1 ft

Step-by-step explanation:

Hello!

[tex]\large\boxed{V = 471cu ft}[/tex]

Find the volume of the cylinder using the formula:

[tex]V = h(\pi r^{2})[/tex]

We are given the diameter, so solve for the radius:

[tex]d = 2r\\\\10 = 2r\\\\r = 5 ft[/tex]

Use the given height and radius to solve for the volume:

[tex]V = 6(5^{2}\pi )\\V = 6 * 25\pi \\\\V = 471 cu ft[/tex]

Step-by-step explanation:

=========================================================

Explanation:

The point (0,0) means x = 0 and y = 0 pair up together.

Recall that any point is always of the form (x,y).

If we plug x = 0 and y = 0 into the equation, we end up with,

y = 3x

0 = 3*0

0 = 0

We get the same thing on both sides, so we have a true equation.

Since we have a true equation, we've shown that  (0,0) is a solution.

Visually this indicates (0,0) is on the line y = 3x. Put another way, the line y = 3x goes through the origin.

Answer:

$19.60

Step-by-step explanation:

245 is 100% of the total.

x is 108% of the total.

245/100 = x/108

245(108) = 26460

26460/100 = 264.6

264.6 - 245 = 19.6

The algebraic expression -5x+6y-3/x is not a polynomial.

The given polynomials are 7-z, 2p³q²-pq³ and -5x+6y-3/x.

A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.

Here,

In 7-z has non-negative integer as exponent

So, it is a polynomial

In 2p³q²-pq³ has non-negative integer as exponent

So, it is a polynomial

In -5x+6y-3/x has negative integer as exponent, which is [tex]x^{-1}[/tex]

So, it is not a polynomial

Hence, the algebraic expression -5x+6y-3/x is not a polynomial.

-(5x2 + 10x - 5)

=

7x^2-5x^2=2x^2

4x-10x=-6x

-9-(-5)=-4
