Answer:
a = 4
Step-by-step explanation:
y = 2x + 1 ......(1)
Going through y - y1 = m(x - x1)
m is slope and it is 2
y1 = 9 and x1 = a
y - 9 = 2(x - a)
y - 9 = 2x - 2a
y = 2x - 2a + 9 ........(2)
Equating (1) and (2)
2x + 1 = 2x - 2a + 9
Collecting like terms
2x - 2x + 2a = 9 - 1
2a = 8
a = 8/2
a = 4
6 numbers per cube
if one is a 1, then the other one has to be a 2, 4 or 6 to be an odd sum
1+2=3, 1+4=5,1+6=7
since there are 3 numbers you can get that would be a 3/6 ( reduce to 1/2) probability
so 1/2 probability
Do 13,500 times .012. Take that answer and multiply it by 10. From that answer, subtract it from 13,500. That would be your final answer.
Answer: D (-∞, ³⁄₂)
1. Find non - negative values for radicals. x ≤ ³⁄₂
2. Find undefined (singularity) points. x = ³⁄₂
3. Combine real regions and undefined points for final domain.
Final answer: x < ³⁄₂
180-24=5
180-56=34
Both are equal
D
