What is the slope of the line? 3x-4y=73x−4y=7
Andrei [34K]
To find the slope, we put this in y = mx + b form where m is ur slope.

3x - 4y = 7.....subtract 3x from both sides
-4y = -3x + 7 ...now we divide both sides by -4
(-4/-4)y = (-3/-4)x + (-7/4)...simplify
y = 3/4x - 7/4

y = mx + b
y = 3/4x - 7/4.....so the number in the m position is 3/4 <== ur slope

a circle has a radius of 9 inches. In inches, what is the length of the arc intercepted by central angle of 3.25 radians
frutty [35]

Answer:

\boxed {\boxed {\sf 29.25 \ inches}}

Step-by-step explanation:

Since we are given the central angle in radians, we should use the following formula for the arc length.

s= \theta r

Where <em>s</em> is the arc length, θ is the angle in radians, and <em>r</em> is the radius.

We know this circle has a radius of 9 inches and the central angle is 3.25 radians.

  • θ= 3.25
  • r= 9 in

Substitute the values into the formula

s= (3.25)( 9 \ in)

Multiply.

s= 29.25 \ in

The arc length is <u>29.25 inches. </u>
