Answer:
(4,-2)
Step-by-step explanation:
plug in and simplify;
y+2=-3(x-4)
-2+2=-3(x-4)
0=-3x+12
3x=12
x=4
No solution.
2y-x=6 =y=1/2x+3
Since 1/2x does not equal 1/2x+3, this is a false statement and therefore has no solution
Answer:
y= 3 when x= 0
y=3
Step-by-step explanation:
in the problem, there's a patten in the difference of X and Y,
at first, Y is 3 more than X (2 and 5)
then y is 4 more, 5 more, and 6 more.
y goes up by 1 each time
so if Y is 5 when X is 2, then when X is 1 Y is 4
when X is 0 Y is 3
The two cars will meet when the sum of the distances covered by the two cars is 330 kilometers.
distance = speed x time.
Let the time covered when they meet be x, then:
80x + 85x = 330
165x = 330
x = 330/165 = 2 hours.
In 2 hours, the canary will cover 90 x 2 = 180 kilometers.
Therefore, the has flown 180 kilometers when the cars collide..
