As 27 will always be equal to 27, you can place whatever you want for x and y and the equation would still be satisfied, as it turns out that it doesn't depend on the x or y value.
Therefore, the system has infinite solutions.
Be safe!
Hi!
The equation to find the area of a triangle is...
(a = area
b = base
h = height)
Fill in the values that we already have.Divide both sides by 1/21722 = 82*h
Divide both sides by 82.1722/82 = 82/82*h
21 = h
The answer is B. 21 cmHope this helps! :)
Answer:
x = s, y = t, z = 8 -s -t
Step-by-step explanation:
It can work reasonably well to let s and t represent any of a pair of the variables. In the answer above, we have used x=s, y=t.
You could get more elaborate if you want:
x = 4-s, y = 4-t, z = s+t
Answer:
Step-by-step explanation:
we have
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
remember that
Answer is a= -5
Reason
Distribute multiply parentheses first
-3(a-8) +4a= -8(a+3)+3
-3a +24 +4a = -8a -24 +3
Now combine like terms to isolate “a”
-3a +4a +8a = -24 +3 -24
9a = -45
Now divide both sides by 9 to solve for “a”
a= -5
