Answer:
c. 0
Step-by-step explanation:
3(x+8) - 1 = 3x+4
3x+24-1 = 3x+4
3x+23 = 3x+4
There are no solutions since both equations have the same slope meaning they are parallel and they will never intersect since they have different y-intercepts.
Answer:
(C) 32
Step-by-step explanation:
This is a problem of Permutation and Combination, not probability.
This clarification is given because most questions like this are on Probability and Statistics.
The researcher has recruited 8 participants and must divide them into two groups of 4 people each.
So there's:
GROUP A - Placebo Group
GROUP B - Experimental Group
Since the experiment is on humans - distinct objects - they will have distinct identities. Assume the 8 participants are lined up according to identities 1,2,3,4, 5,6,7,8
[2+2+2+2 +2+2+2+2] × 2 = 16×2 = 32
Answer:
y = (x+2)²-2
Step-by-step explanation:
Use the vertex form y = a(x-h)²+k. Plug in the vertex for h and k. Solve for a and you will get 1 for that value. You can check your answers by plugging in both of those points to make sure.
The line of symmetry can never be symmetrical. If you put a vertical line through the middle the sides aren't equal. Same for horizontal and diagonal.
First, convert 3 8/10 and 5 7/9 to improper fractions:
• 38/10 + 52/9
Next, find a common denominator, which is 90:
• 38/10 * 9 = 342/90
• 52/9 * 10 = 520/90
Now add them together and you’ll get 862/90.
It can be reduced to 431/45 or 9 26/45.
