Answer:

628

Step-by-step explanation:

Deposit means money is going into the bank so add 129 onto 499

(b) writing a cheque means money is coming out of the bank so subtract 24 from your previous answer.

628 - 24 = 604

(d) round 604 to the nearest hundred

(it's between 600 and 610 but which is it closest to?)

Part A: If (72)x = 1, what is the value of x? Explain your answer. (5 points)

vichka [17]

Answer:

see below

Step-by-step explanation:

Part A: (72)^x = 1

Take the log base 72 of each side

log72(72^x) = log 72(1)

We know log a^b = b log a

x log72(72) = log72(1)

x = log72(1)

x = 0

Part A: (70)^x = 1

Take the log base 70 of each side

log70(70^x) = log70(1)

We know log a^b = b log a

x log70(70) = log70(1)

x = log70(1)

x = 0

–4x – 7 = y x2 – 2x – 6 = y Which statement is true? There are no real number solutions. There is one unique real number solutio

Aleksandr [31]

Answer:

<h3>There is one unique real number solution at (–1, –3)</h3>

Step-by-step explanation:

Given the two linear equation

–4x – 7 = y ...1

x² – 2x – 6 = y ...2

Equating the left hand side of both equations since they are equal to the same variable y will give;

$-4x-7=x^{2} -2x-6\\collecting\ the\ like\ terms\\x^{2} -2x+4x-6+7 = 0\\x^{2} +2x+1 = 0\\x^{2} +x+x+1 = 0\\x(x+1)+1(x+1)=0\\(x+1)^{2}=0\\ taking\ square\ root\ of\ both\ sides\\x+1 = 0\\x = -1\\$

Substituting x=1 into equation 1 we have;

$y=-4(-1)-7\\y=4-7\\y = -3$

This means there is only one unique real number solution at (-1, -3)
