Answer:
The required integer is -15.
Step-by-step explanation:
Given,
The temperature dropped 3°c every hour,
So, the change in temperature every hour = -3°C
Total number of hours for which the temperature were changed = 5,
Thus, the total change in temperature = change for an hour × total number of hours,
= -3° × 5
= -15°
Hence, the integer that represents the change in temperature is -15.
i think its D
sry if im wrong
step-by-step explanation:
XZ,X(-10,9)
Y(-4,8)
is
X2,YZ(14-1)=12
x=16 x=2
x^2-18x+81=49
x^2-18x+81-49=0
x^2-18x+32=0
(x-16)(x-2)=0
x-16=0
+16+16
x=16
x-2=0
+2 +2
x=2
