Answer:
y = 3x - 31
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 = 3, thus
y = 3x + c ← is the partial equation
To find c substitute (9, - 4) into the partial equation
- 4 = 27 + c ⇒ c = - 4 - 27 = - 31
y = 3x - 31 ← equation in slope- intercept form
Answer:
A
Step-by-step explanation:
15*18=270.
270-46.50=223.5
223.5-129.95=93.55.
A. $93.55
0.8888888 = 8/9
2.8888888 = 26/9
-2.888888 = -26/9
Answer:
229.18 degrees
Step-by-step explanation:
The circumference of a circle with radius r is 2×pi×r.
So if it has a radius of 1 mile, then the circumference is 2×pi×1=2pi miles.
So if we travel 4 miles, then the percentage of this circle we traveled is 4/(2pi)=63.66% approximately.
There are 360 degrees in a circle and we want to how much of that rotation belongs to traveling 4 miles of the circumference of a circle that measures 2pi miles. So 63.66%×360 degrees =229.18 degrees.
