Step-by-step explanation:
3^-1 = .33333333
1/4 = .25
1. y = 2/3x - 5
2. 4x - 6y = 30
Divide 2. by 2
3. 2x - 3y = 15
Substitute 1. into 3.
4. 2x - 3(2/3x - 5) = 15
5. 2x - 2x + 15 = 15
6. 15 = 15
False. There are an infinite number of solutions.

Step-by-step explanation:
Answer:
a) 1/2
Step-by-step explanation:
All we have to do is simply find the probability of selecting a triangle, find the probability of selecting a circle and then add them together.
There are a total of 10 shapes in the box.
There are 3 triangles, so, the probability of picking a triangle is:
3/10
There are 2 circles, so, the probability of selecting a circle is:
2/10
Adding them together yields:
3/10 + 2/10 = 5/10 = 1/2
The probability of selecting a triangle or circle is 1/2.
