Answer:
There is no solution to this system of equations. So the answer will be No Solution.
Step-by-step explanation:
Since the lines never intersect and are parallel there can be no solution. Hope this helps
Answer:

Step-by-step explanation:
To factor the equation, break it into two binomials which multiply to make the equation. To write these binomials (x+a)(x+b), find factors which multiply to 30 and add to -13 for a and b.
30: 1, 2, 3, 5, 6, 10, 15, 30
-3+-10 = -13

Answer:
C
Step-by-step explanation:
They would be 3x more likely to choose football over tennis, since tennis is 13 and football is 39
39/3=13
Final answer is C
Since a right triangle has special rules to it such that the hypotenuse squared equals the sum of the squares of the other 2 sides. In other words, if the hypotenuse = c, and the 2 smaller sides are a and b, then:

Solving for c (hypotenuse), we get:

Therefore c is the root of the square of the other sides. So by having root18, it's like saying:

Getting rid of the square root, so sides a and b must have their squares total 18:
the only squares < 18 are: 16 (4×4), 9 (3×3), 4 (2×2), and 1 (1×1)
of those above added in any order of two of them, only 16+4



I HOPE THAT IS ALONG THE LINE THAT WAS ASKED FOR!!! :-D
Multiply the number of attempts with the probability,
160 x 0.8 = 128 attempts made.
Hope this helps.
