Answer:

These four points fall on that line:

(-1, 7), (0, 3), (0.75, 0), (1, -1)

To graph it, just plot any two of those points (as it's a linear equation), and trace the line that they both fall on.

Step-by-step explanation:

The easiest points to find usually involve one of the coordinates being equal to zero, one or another simple number. So with that in mind:

if x = 0, then y = 0 + 3 = 3

if x = 1, then y = -4 + 3, which equals -1

if x = -1, then y = 4 + 3, which equals 7

if y = 0, then -4x + 3 = 0, so 4x = 3, and x = 3/4, or 0.75

That gives us the points (-1, 7), (0, 3), (0.75, 0), (1, -1)

All you have to do is to reverse the order of the x and y components of (7,2):
(2,7).

Suppose two radii of a circle determine a 45° angle, and the length of both radii is 64 yards. What is the arc length formed by

Ilia_Sergeevich [38]

The arc length formed by the 2 radio is 15.24 yards

Step-by-step explanation:

Angle between the 2 radio = 45°

Radius = 64 yards

Arc length = (45/360) (2π) (64)

= (1/8) (2π) (64

= 16π

= 16(3.14)

=15.24 yards

The arc length formed by the 2 radio is 15.24 yards

C+ax=dx this one has all variables and no numbers

sergeinik [125]

That's OK, but you have not said which variable you want to solve it for.

To solve for 'x':
 c + ax = dx

Subtract c from each side: ax = dx - c

Subtract dx from each side: ax - dx = -c

Factor the left side: x (a - d) = -c

Divide each side by (a - d) : x = -c / (a - d) or x = c / (d - a) .

To solve for 'c': 
 c + ax = dx

Subtract ax from each side and factor: c = x (d - a) 

To solve for 'd': 
 c + ax = dx

Divide each side by 'x': d = c/x + a .

To solve for 'a':
 c + ax = dx

Subtract 'c' from each side: ax = dx - c

Divide each side by 'x': a = d - c/x .
