Answer:
C. Points F, J, and H are collinear.
Step-by-step explanation:
Given
See attachment for triangle
Required
Which statement is false
Options A, B and D are true while C is false.
Two points are said to collinear if a straight line can pass through them.
From the attached triangle, we can see that a straight line cannot pass through F, J and H.
Hence, they are not collinear.
<em>Since the statement is false, then it cannot be used as part of the proof.</em>
Answer:
A) t = -3
Step-by-step explanation:
We have the expression and we have to find the value of t.
First we are going to reorder the expression:
Now we have to multiply each side by 2,
Subtract (-12) in both sides,
Divide both sides in 2,
The answer is option A) t = -3.
Answer: c. 7,999,999 phone numbers
A can be any digit 2-9, then there are 8 possible numbers.
B can be any digit 0-9, then there are 10 possible numbers.
C can be any digit 0-9, then there are 10 possible numbers.
X can be any digit 0-9, then there are 10 possible numbers.
X can be any digit 0-9, then there are 10 possible numbers.
X can be any digit 0-9, then there are 10 possible numbers.
X can be any digit 0-9, then there are 10 possible numbers.
Then are possible: 8·10·10·10·10·10·10 = 8·10⁶ = 8,000,000 phone numbers
But the number 867-5309 is not used then 8,000,000 - 1 = 7,999,999 possible phone numbers.
Answer: c. 7,999,999 phone numbers
