What’s the equation for A slope =2 through the point (2,1)?

Mathematics

Answer:

y = 2x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, thus

y = 2x + c ← is the partial equation of the line

To find c substitute (2, 1) into the partial equation

1 = 4 + c ⇒ c = 1 - 4 = - 3

y = 2x - 3 ← equation of line

What is the x-coordinate of the solution of the system?<br> x+y+3<br> 4x-y=-38
steposvetlana [31]

<em>Note: I am assuming the first equation is:</em>

<em>x+y = 3</em>

Answer:

The solution to the system of equations is:

(x, y) = (-2, 36)

Therefore, the x-coordinate of the solution of the system

x = -2

Step-by-step explanation:

Given the system of equations

\begin{bmatrix}x+y=34\\ x-y=-38\end{bmatrix}

subtracting the equations

x-y=-38

-

\underline{x+y=34}

-2y=-72

solve -2y for y

-2y=-72

Divide both sides by -2

\frac{-2y}{-2}=\frac{-72}{-2}

y=36

For x+y=34 plug in y = 36

x+36=34

Subtract 36 from both sides

x+36-36=34-36

Simplify

x=-2

Thus, the solution to the system of equations is:

(x, y) = (-2, 36)

Therefore, the x-coordinate of the solution of the system

x = -2

how to find the area of each circle. use a calculator value of pi. round the answer to the nearest tenth
tankabanditka [31]

Answer:

A = 201.0 mi^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We know that r = 8

A = (3.14) *8^2

A = 3.14 * 64

A = 200.96 mi ^2

Rounding to the nearest tenth

A = 201.0 mi^2
