N is equal to 11 because 5-2n=17 would be changed into 2n-5=17 because it would be -17 if it was the original problem so that is why
Answer:
A, C and D
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 (- 1, 4) into the partial equation
4 = 3 + c ⇒ c = 4 - 3 = 1
y = - 3x + 1 ← in slope- intercept form → C
Add 3x to both sides
3x + y = 1 ← in standard form → A
-----------------------------------------------------------
The equation of a line in slope- intercept form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = - 3 and (a, b) = (- 1, 4), thus
y - 4 = - 3(x + 1) ← in point- slope form → D
Answer:
12:07 pm
Step-by-step explanation:
The question is on relative speed
<u>Calculate the distance covered by truck after 3hours and 10 minutes</u>
Given; speed of truck= 40mph
Time the truck took to travel before the car started to drive from point A= 3h 10 minutes
Change hours to minutes= (60×3) + 10 = 190 minutes
Formulae for speed, S=d/t where S is speed of truck, d is distance covered and t is time
if S=d/t then distance d=S×t
d= 40×190/60 =380/3 =126.67 miles
<u>Finding the time the car catch up with the truck</u>
t=d/S where d=126.67 miles and speed of car = 60mph
t= 126.67/60 = 2.11 hours
Change hours to minutes
1 hr=60minutes
2.11 hrs= 2.11×60=126.67 minutes⇒2hrs and 6.67 minutes
t⇒2 hrs 7minutes
Add to the departure time
10.00 + 2: 07 = 12:07 pm
