Answer:
Step-by-step explanation:
Given is an equation in xy as xy =12
WE are to complete the coordinate table for xy =12
Let us give different values for x and find corresponding values of y
Note that x or y cannot equal 0 in this
So let us give other values
x y
12 1
6 2
4 3
3 4
2 6
1 12
-1 -12
-2 -6
-3 -4
-4 -3
-5 -2.4
-6 -2
-12 -1
Answer:
1 spider, 3 cows, 5 birds.
Step-by-step explanation:
Cows (C): 4 legs, 2 eyes.
Birds (B): 2 legs, 2 eyes.
Spiders (S): 8 legs, 4 eyes.
The number of legs and eyes are given, respectively by:
Multiplying the second equation by -2 and adding it to the first one gives us the number of birds:
Rewriting the original equations with B =5:
Since the number of cows cannot be negative, and both C and S must be odd numbers, the only possible value of S is 1:

Answer:
140°
Step-by-step explanation:
<u>Given:</u>
Dana draws a triangle with one angle that has a measure of 40∘.
<u>Question asked:</u>
What is the measure of the angle’s adjacent exterior angle?
Solution:
<u>As we know:</u>
<u><em>Sum of the adjacent interior and exterior angles is 180°.</em></u>
Interior angle = 40°
Adjacent exterior angle = ?
Interior angle + Adjacent exterior angle = 180°
40° + Adjacent exterior angle = 180°
<u>By subtracting both sides by 40°</u>
40° - 40° + Adjacent exterior angle = 180° - 40°
Adjacent exterior angle = 140°
Therefore, the measure of the angle’s adjacent exterior angle will be 140°.
Answer:
x=4 and y=(-6)
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
