Answer:
yes it is a right triangle
it started at -10.5 then rose 5.2
-10.5 +5.2 = -5.3
then fell 3.6
-5.3 - 3.6 = -8.9
so it was -8.9 degrees Celcius
Answer:
B
Step-by-step explanation:
the question says -12x ≤ -72.the sign ≤ means less than or equal to. so we will divide both sides by -12 to get the value of x. and that wil give us x ≤ 6, the sign did not change because we used a sign common to both sides to divide it. that is slso the reason why we had a positive value.
Answer:
