Answer:
26
Step-by-step explanation:
18 - 2^4 * (-0.5)
Calculate 2 to the power of 4 and get 16.
18−16(−0.5)
Multiply 16 and −0.5 to get −8.
18−(−8)
The opposite of −8 is 8.
18+8
Add 18 and 8 to get 26.

Answer:
y=0
Step-by-step explanation:
The equation for the slope is
m = ( y2-y1)/(x2-x1)
-2 = (4-y)/(1-3)
-2 = (4-y)/-2
Multiply each side by -2
4 = 4-y
Subtract 4 from each side
4-4 = 4-y-4
0 = -y
0=y
It is 46/7 you could multiply 6x7 and then add 4 = 46/7
Answer:
the answer of the question is 9.5
Assume temp T = T0 (75 0) at Noon (00), To find out T after 4 hours at 4 p.m. or at the 8th period, each period being 0.5 hour. If the relationship is linear, i.e if temperature is dropping linearly each half an hour by 3 0, the T is a staight line T=m*t+ T0, in which the slope m=∇T/∇t = (-30/0.5 hr) = -60/hour (negative slope decreasing)
So at 4 p.m. for t=4, temp T = 750 -60/hour*4 hour= 750-240= 510
