Answer:
Yes the relationship is linear and given by:
(first option of your list)
Step-by-step explanation:
Yes, it is a linear expression. As we did in previous exercises, we calculate the difference between consecutive y values of the table, and write down the answers we get:
-7-(-2) = -7+2 = -5
-12-(-7) = -12 +7 = -5
-17 - (-12) = -17 + 12 = -5
We notice that all of them give "-5"
Now we evaluate the difference between consecutive x-values in a similar fashion:
-5 -(-9) = -5+9 = 4
-1-(-5) = -1+5 = 4
3-(-1) = 3+1 = 4
We see that they all give 4 as the difference.
That means that the rate of change 
This means that the slope (rate of change) of the line is "-5/4"
We can now use the general point-slope form to write the equation of the line, using the first pair of the table as our selected point, and using "-5/4" for the slope:
which is the first expression listed among your possible answer choices.
Answer:
Neither
Step-by-step explanation:
Can be determined because there is enough information (Length, width, and height).
Not congruent because from the picture itself, the figures are in different sizes.
Not similar because:
The height ratio is not the same as the ratios of other dimensions.
1 : 4 is not similar to 6 : 12 and 4 : 8
Answer:
take 45 degree as reference angle
use sin rule
sin 45=opposite/hypotenuse
1/
=b/10(do cross multiplication)
b=10
b=10/
Step-by-step explanation:
Answer:
- <u><em>31 animals</em></u>
Explanation:
The question is in French language. The translation to English is:
<em>1 rabbit saw 6 elephants while going to the river. Each elephant saw 2 monkeys go towards the river. Each monkey holds 1 parrot in its hands.</em>
<em>How many animals are going to the river?</em>
<em />
<h2>Solution</h2>
<em />
Animal amount
Rabbit 1
Elephants 6 (the rabbit saw 6 elephants)
Monkeys: 6 × 2 = 12 (2 monkeys per elephant)
Parrots: 12 × 1 = 12 (1 parrot per monkey)
=============================
Total: 1 + 6 + 12 + 12 = 31 animals ← answer
