<u><em>Answer:</em></u>
-9
<u><em>Explanation:</em></u>
<u>From the first three </u><span><u>triominoes, we can note that:</u>
number on center = -first base - second base + vertex
<u>This is verified as follows:</u>
<u>For the first one:</u>
The two bases are 7 and 9 and the vertex is 1
- first base - second base + vertex = -7 -9 + 1 = -16 + 1 = -15
<u>For the second one:</u>
The two bases are 0 and 9 and the vertex is 8
- first base - second base + vertex = -0 -9 + 8 = -9 + 8 = -1
<u>For the third one:</u>
The two bases are 6 and 4 and the vertex is 2
- first base - second base + vertex = -6 - 4 + 2 = -10 + 2 = -8
<u>Applying the same procedure on the last one:</u>
The two bases are 7 and 2 and the vertex is 0
-first base - second base + vertex = -7 - 2 + 0 = -9 + 0 = -9
Hope this helps :)</span>

Answer:
51
Step-by-step explanation:
Given parameters:
Number of heads = 30 heads
Number of legs = 84 legs
Unknown:
Number of chickens and pigs = ?
Solution:
Since a chicken has one head, the number of chicken is the same as the number of heads;
Number of chicken = 30
A pig has 4 legs,
Number of pigs =
= 21pigs
Total number of pigs and chickens = 30chickens + 21 pigs = 51

y = 3x - 3
If a line is perpendicular to another line, they have negative reciprocal slopes.
So you would use the slope -1/3.
Use y - y₁ = m(x - x₁) to get an equation in slope intercept form.
Plug the numbers in.
y - 1 = -1/3(x - 3)
y - 1 = -1/3x + 1
y = -1/3x + 2
An equation of a line perpendicular to line CD is y = -1/3x + 2.
Given:
total cost : 28.70
cost per pint of fruit : 2.85
Formula:
5v + 7f = 28.70
5v + 7(2.85) = 28.70
5v + 19.95 = 28.70
5v = 28.70 - 19.95
5v = 8.75
5v/5 = 8.75/5
v = 1.75 cost per pint of veggies.
to check:
v = 1.75 ; f = 2.85 ; total cost = 28.70
5v + 7f = 28.70
5(1.75) + 7(2.85) = 28.70
8.75 + 19.95 = 28.70
28.70 = 28.70
