for a all you have to do is * you will find the answer. for b what ever yo answer was for a u will put that for the hours n what u had * u put for min for seconds
X=number of hours you read
y=number of pages
y=30x+70
number of pages after 3 hours:
y=30(3)+70
y=90+70
y=160
therefore, 160 pages after 3 hours

Answer:
a) SPAZ is equilateral.
b) Diagonals SA and PZ are perpendicular to each other.
c) Diagonals SA and PZ bisect each other.
Step-by-step explanation:
At first we form the triangle with the help of a graphing tool and whose result is attached below. It seems to be a paralellogram.
a) If figure is equilateral, then SP = PA = AZ = ZS:
![SP = \sqrt{[4-(-4)]^{2}+[(-2)-(-4)]^{2}}](https://tex.z-dn.net/?f=SP%20%3D%20%5Csqrt%7B%5B4-%28-4%29%5D%5E%7B2%7D%2B%5B%28-2%29-%28-4%29%5D%5E%7B2%7D%7D)
![PA = \sqrt{(6-4)^{2}+[6-(-2)]^{2}}](https://tex.z-dn.net/?f=PA%20%3D%20%5Csqrt%7B%286-4%29%5E%7B2%7D%2B%5B6-%28-2%29%5D%5E%7B2%7D%7D)
![ZS = \sqrt{[-4-(-2)]^{2}+(-4-4)^{2}}](https://tex.z-dn.net/?f=ZS%20%3D%20%5Csqrt%7B%5B-4-%28-2%29%5D%5E%7B2%7D%2B%28-4-4%29%5E%7B2%7D%7D)
Therefore, SPAZ is equilateral.
b) We use the slope formula to determine the inclination of diagonals SA and PZ:
Since 
, diagonals SA and PZ are perpendicular to each other.
c) The diagonals bisect each other if and only if both have the same midpoint. Now we proceed to determine the midpoints of each diagonal:
Then, the diagonals SA and PZ bisect each other.
Answer:
elevation of 3,234 feet above sea level Positive
losing $32.50 Negative
depositing $230 in an account Positive
withdrawing $2,432 from an account Negative
2°C below 0°C Negative
10 floors above ground level Positive
Step-by-step explanation:
elevation of 3,234 feet above sea level Positive This is above ground
losing $32.50 Negative it is less than you had
depositing $230 in an account Positive putting money in
withdrawing $2,432 from an account Negative taking money out
2°C below 0°C less than 0
10 floors above ground level above 0
Answer:
Yes
Step-by-step explanation:
