Solve The Following System of equations by graphing 3x + y = 5 x - 4y = 32

Nostrana [21]

first you convert to slope intercept form

3x+y = 5 is the same as y = -3x+5

x - 4y = 32 is the same as y = 4x-8

then you graph

(starting with the y-intercepts as your first points)

the point where the two lines intercept is your solution.

What is the value of n in the equation 1/2(n – 4) – 3 = 3 – (2n + 3)?

Travka [436]

Distribute 1/2 to (n – 4):

 $\frac{1}{2} \times n = \frac{1}{2}n$
$\frac{1}{2} \times -4 = -2$

Subtract (2n + 3):

 $- (2n + 3) = -2n -3$

Your equation should now look like this:

 $\frac{1}{2}n - 2 - 3 = 3 - 2n - 3$

Combine like terms on both sides:

 $-2 - 3 = -5$
$3 - 3 = 0$
$\frac{1}{2}n - 5 = -2n$

Subtract 1/2n from both sides:

 $-5 = -\frac{5}{2}n$

Divide both sides by -5/2 to get n by itself:

 $n = 2$

The value of n is 2.

A tangent is >insert answer here< to the radius that shares the point of tangency

tatuchka [14]

A tangent line is always perpendicular to the radius that shares the point of tangency. In other words, where your tangent line touches the circle (at only one point), that line is perpendicular to the radius at that point.
