Answer: y = x/2 + 3
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = intercept
Slope, m = change in value of y on the vertical axis / change in value of x on the horizontal axis
change in the value of y = y2 - y1
Change in value of x = x2 -x1
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
Looking at the graph,
y2 = 6
y1 = 4
x2 = 6
x1 = 2
Slope,m = (6 - 4)/(6 - 2) = 2/4 = 1/2
To determine the intercept, we would substitute x = 2, y = 4 and m= 1/2 into y = mx + c. It becomes
4 = 1/2 × 2 + c
4 = 1 + c
c = 4 - 1
c = 3
The equation becomes
y = x/2 + 3
Answer:
3.15
Step-by-step explanation:
4.99x.45=2.25 discount
4.99-2.25=2.74 sales price
2.74x.15=.41 sales tax
2.74+.41=3.15 total price
A) Linear velocity, v = ωr ω = Angular velocity, r = radius.
<span>ω = 5 revolutions per minute. 1 minute = (1/60) hour. </span>
<span>= 5*2π radians / (1/60) hour = 600π radians per hour π = 3.14 </span>
= 600*3.14 = 1884 radians / hour
<span>but radius, r = 10 feet, 5280 feet = 1 mile, 10 feet = (10/5280) mile </span>
Linear velocity, v = ωr
<span> v = 1884 radians / hour * (10/5280) mile </span>
v ≈ 3.568 miles / hour<span />
Answer:
Its 8% more on the whole amount. or use (Price x 1.08) to calculate total price
