The distances (y), in miles, of two cars from their starting points at certain times (x), in hours, are shown by the equations below:Car A
y = 55x + 32
Car B
y = 42x + 58
After how many hours will the two cars be at the same distance from their starting point and what will that distance be?
2 hours, 142 miles
2 hours, 145 miles
3 hours, 142 miles
3 hours, 145 miles
Answers
Answer:
Option A is correct
2 hours, 142 miles
Step-by-step explanation:
As per the statement:
The distances (y), in miles, of two cars from their starting points at certain times (x), in hours, are shown by the equations below:
Car A
y = 55x + 32 ....[1]
Car B
y = 42x + 58 ....[2]
We have to find after how many hours will the two cars be at the same distance from their starting point.
Since, two cars be at the same distance
equate [1] and [2] ;
⇒
Subtract 42x from both sides we have;
⇒
Subtract 32 from both sides we have;
Divide both sides by 13 we have;
x = 2 hours
Substitute in [1] we have;
miles
Therefore, after 2 hours will the two cars be at the same distance from their starting point and 142 miles will that distance be
42x+58=55x+32
13x=26
x=2hrs <---- answer
42*2+58=142
55*2+32=142mi <----answer

Answer:
(4, 7 )
Step-by-step explanation:
given the 2 equations
3x - 8y + 44 = 0 → (1)
7x = 12y - 56 ( subtract 12y - 56 from bpth sides )
7x - 12y + 56 = 0 → (2)
multiplying (1) by 7 and (2) by - 3 and adding the result will eliminate x
21x - 56y + 308 = 0 → (3)
-21x + 36y - 168 = 0 → (4)
add (3) and (4) term by term to eliminate x
(21x - 21x) + (- 56y + 36y) + (308 - 168) = 0
0 - 20y + 140 = 0 ( subtract 140 from both sides )
- 20y = - 140 ( divide both sides by - 20 )
y = 7
substitute y = 7 into either of the 2 orinal equations and solve for x
substituting into (1)
3x - 8(7) + 44 = 0
3x - 56 + 44 = 0
3x - 12 = 0 ( add 12 to both sides )
3x = 12 ( divide both sides by 3 )
x = 4
solution is (4, 7 )
