Answer:
The point of intersection is (6, 8). This indicates that in 6 days, asteroid A and B will collide at a point that is 8 million miles away from asteroid A's current position and 12 million miles away from asteroid B's current position.
3(x - 1) = 2x + 9
3x - 3 = 2x + 9
3x (-2x) -3 (+3) = 2x (-2x) + 9 (+9)
(3x -2x) = (9 + 9)
(x) = (18)
x = 18
x = 18 is your answer
hope this helps
Answer:
The answer is A.
Step-by-step explanation:
Given that Winnona took 5 tests and retake Test 5. So the mean score for this question is Total number of scores divide by Total number of tests is equals to 87 :
Let Test 5's score be x,
Let mean score be 87,
Next you have to solve the value of x :
Answer:
C-----> x<-7
Step-by-step explanation:
first u do this to turn x in positive and consequently change the > to an <:
(-1).(-4x)>28.(-1)
so:
4x<-28
x<-7
# when multiplying each side by (-1), you have to change the symbol (>) to an (<), or (<) to an (>)
(2x-5)(3x-1)=0
2x-5 = 0 or 3x-1= 0
2x = 5 3x = 1
x = 5/2 x = 1/3
Answer: x=5/2; x=1/3
