Answer -4
3(0)^2= 0
-10(0)= 0
-4+0+0= -4
Answer:
x = -7.33 OR x = 
y = 13
Step-by-step explanation:
<u>→You can use the substitution method. First, make y by itself in (-2 + 2y = 24):</u>
-2 + 2y = 24
2y = 26
y = 13
<u>→Then, plug in 13 for y into the other equation:</u>
3x + 2y = 4
3x + 2(13) = 4
3x + 26 = 4
3x = -22
x = -7.33 OR x = 
There are 43 small dogs signed up in the competition
<h3>How to determine the number of small dogs?</h3>
Represent the small dogs with x and the large dogs with y.
So, we have the following equations
x + y = 50
x = 36 + y
Make y the subject in x = 36 + y
y = x - 36
Substitute y = x - 36 in x + y = 50
x + x - 36 = 50
Evaluate the like terms
2x = 86
Divide both sides by 2
x = 43
Hence, there are 43 small dogs in the competition
