Let the distance be D miles
Car A:- D = 2.4R and for Car B:- D = 4(R- 22)
therefore 2.4R = 4(R-22)
4R - 88 = 2.4R
1.6R = 88
R = 55mph Answer
Answer:
Step-by-step explanation:
The minimum daily requirement of vitamin c for a 14 year old is at least 50 milligrams per day. This means that it cannot be lesser than 50 milligrams.
An average sized apple contains 6 milligrams of vitamin c.
50 milligrams / 6 = 8.333 apples
Since the least amount per day is 50 milligrams and the apple is whole, the least number of apples will be 9 apples
The 14 year old will have to eat at least 9 apples each day to satisfy this requirement.
The equation in slope-intercept form represents a line that is parallel to y = 12x − 2 and passes through the point (−8,1) is y = 12x + 97
<em><u>Solution:</u></em>
Given that we have to write the equation in slope intercept form for line that is parallel to y = 12x − 2 and passes through the point (−8, 1)
<em><u>The slope intercept form is given as:</u></em>
y = mx + c ---- eqn 1
Where "m" is the slope of line and "c" is the y - intercept
Given equation of line is y = 12x - 2
On comparing the above equation with eqn 1,
m = 12
Thus slope of line is 12
We know that slopes of parallel lines are equal
Therefore, slope of line parallel to given line is also 12
Given point is (-8, 1)
We have to find the equation of line passing through (-8, 1) with slope m = 12
Substitute m = 12 and (x, y) = (-8, 1) in eqn 1
1 = 12(-8) + c
1 = -96 + c
c = 97
Substitute c = 97 and m = 12 in eqn 1
y = 12x + 97
Thus the required equation of line is found
