The answer to whether an equation can be true or false is; Yes
<h3>Equations</h3>
Yes an equation can be true or false. This is because for example if we have the equation;
3x + 5 < 12
For this equation to hold true, only certain values of x can be possible which we will call as possible solutions. Whereas any values outside of the possible range of x will make the equation to be false.

Answer:
p = 1.25
Step-by-step explanation:
varies inversely
p (q + 2)² = k
-----------------------
Find k
p=5 when q = 3
5(3 + 2)² = k
5(25) = k
125 = k
----------------------
Find p when q = 8
p(8 + 2)² = 125
p(100) = 125
divide both sides by 100
p = 1.25
Answer:
Step-by-step explanation:
11 degrees. 13 + -2 = 11. The starting temperature was 11 degrees farenheit
Move the 1st equation to get y by itself so it’s now y=-4x so you can substitute that in for the second equation 2y+x=-7 becomes 2(-4x)+x=-7
-8x+x=-7
-7x=-7
x=1
then plug that back in to find y
4(1)+y=0
4+y=0
y=-4
now you have x and y so your coordinate (the answer) is (1, -4) hope this helps!
