-5x=-35
divide both sides by -5
-5x/-5 = -35/-5
simplify
x = 7
Answer:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 1010. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
7.1×1047.1×104
Answer:
Rate of change = -30
Initial value = 400
Step-by-step explanation:
Write the equation of the linear function representing this situation. Let
x = number of weeks Gandalf is spending money
y = amount of quibbles left in his account.
Gandalf has 400 quibbles in his account. This means,
is the initial value of quibbles Gandalf had in his account
He spends 30 quibbles each week, this means, that he spends 30x quibbles in x weeks and the amount left in his account is
![y=400-30x](https://tex.z-dn.net/?f=y%3D400-30x)
Therefore, the slope is
and this is the rate of change (negative because the amount of money in his account decreases each week)
