Step-by-step explanation:

The associative property for multiplication: <em>(a · b) · c = a · (b · c)</em>

-\dfrac{5}{6}\cdot(12\cdot87)=\left(-\dfrac{5}{6\!\!\!\!\diagup_1}\cdot12\!\!\!\!\!\diagup^2\right)\cdot87=(-5\cdot2)\cdot87=(-10)(87)=-870

Could someone explain this to me
Bond [772]

Answer:

Step-by-step explanation:

The question is asking you to graph the equations.

The equations are in slope intercept form so y=mx+b

M is the slope and b is the y-intercept

First draw the y & x axis and label/number them

The y-intercept for the first equation is -1 so draw a dot on the -1 on the y-axis

The slope is 2/5 and you use rise/run to continue the slope.

you rise 2 on the y-axis and go right 5 times on the x-axis (for a negative number you go left/down)

For the second equation, you have to turn it into slope intercept form.

You should get y=2/3x+3

You graph this equation the same as you did the first one.

Olenka [21]

The question is an illustration of the Truth in Lending Act, and Dan is responsible for paying $0

<h3>Truth in Lending Act</h3>

The Truth in Lending Act is simply an act that protects people from unfair charges on their credit cards, especially in case of theft and card misplacement.

<h3>The scenarios</h3>

From the question, we have the following scenarios

  • His card got lost
  • He reported
  • Someone else saw the card and purchased goods worth over $200

Because Dan reported when his card got lost, he is protected by the Truth in Lending Act (TILA).

Hence, Dan is responsible for paying $0
