Answer:
-5/4
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( -3 -2)/( 3 - -1)
= ( -3-2 ) /( 3+1)
= -5/4
Answer:
P = 25/42
Step-by-step explanation:
We are asked to calculate the probability that if two items are selected from two different boxes, what is the probability that bought are non-defective.
In the first box A, the probability of selecting a non-defective item is 5/7
In the second box B, the probability of selecting a non-defective item is 5/6
Now the probability of selecting 2 items, one from each of the boxes and both are non-defective are as follows;
5/6 * 5/7 = 25/42
Answer: if you know the square find the GCF
Step-by-step explanation: List the prime factors of each number.
Circle every common prime factor — that is, every prime factor that's a factor of every number in the set.
Multiply all the circled numbers. The result is the GCF. Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers. The square root of a number, n, written below is the number that gives n when multiplied by itself.
Answer:
x = 3
Step-by-step explanation:
x + 3 = 4x - 6
add 6 to both sides
x + 9 = 4x
subtract x from both sides
9 = 3x
divide 3 from both sides
x = 3
12 multiply by $45. Or divide $45 into $540 = 12
