We know that the slope is -5, so:
y = -5x + b
Input (1, 2)
2 = -5 + b
b = 7
So:
y = -5x + 7
Let's analyse each option:
A.
Spending money means the money will decrease, so it would be represented by minus 32.
B.
Dropping a rock means its height will decrease, so minus 32 would fit better.
C.
The speed is decreasing, so minus 32 as well.
D.
The amount of books is increasing, so positive 32 fits better in this situation.
Therefore the correct option is D.
(B)
Step-by-step explanation:
Look at the triangle with the 65° angle. Note that the 65° angle is opposite the 24-ft side and p is the length of the triangle's hypotenuse so let's use the definition of sine 65°:
sin 65 = opposite/hypotenuse
= (24 ft)/p
Solving for p,
p = (24 ft)/(sin 65°)
= 26.48 ft
Answer:
They are the same
Step-by-step explanation:
One hundred draws are made at random.
The average of a list of numbers equals the sum of the numbers divided by how many numbers there are.
So, when the sum of the 100 draws is 710, the average of the draws will be
710/100 = 7.1
So, when the sum of the draws is bigger than 710, the average of the draws will be bigger than 7.1.
Therefore, the two chances are the same.
Answer:
323
Step-by-step explanation:
first of all we solve the bracket using bodmas then we multiply the thirty three by one one two then we multiply the minus sign by the answer we got earlier then we multiply the minus outside the whole bracket by the bracket then we add it to the number in front of the bracket
